Wildlife Crime

  Wildlife Crime

Wildlife crimes involve the illegal killing, maiming or harassing of any wild animal. These crimes include killing animals without a permit, fishing or hunting out of season, killing more than the permitted number of a particular species, harassing wildlife, illegally baiting trail cameras, capturing wild animals for the exotic pet trade, taking the body parts of animals for decoration or “medicinal” uses, poisoning and much more. These are not only crimes against wildlife and nature, but also against anyone who derives enjoyment for the natural world. Whether actions like these are intentional or not, they should always be reported.

Crimes Against the WildWildlife crime is a more common problem in the United States than most people think.

Statistics regarding crimes involving wild animals native to the United States are difficult to come by. Much of the focus is on trafficking of exotic species from other nations. But our wild animals here at home are also at risk. Gamewarden.org emphasizes that poaching is “straining the resources of our nation’s game wardens and other law enforcement officers and decimating animal species at alarming rates.”

Unfortunately, assessing the full extent to which poaching, poisoning or “shoot, shovel, and shut up” occurs can be extremely difficult as these crimes are seldom reported. Even when there is sufficient evidence that a crime has been committed, it can be problematic to find and convict the offending party.

Poaching poses a significant issue for wildlife managers whose primary purpose is to protect and preserve biodiversity. If wild animals are being killed illegally and these deaths go unreported, then it is difficult for managers to efficiently oversee the well-being of a species. When people keep a careful eye on social media, they can sometimes bring questionable activities to the attention of authorities.

In May of 2018, CNN reported on a poaching operation in the Pacific Northwest that gives a sense of the scale these crimes can reach. The report details that “over text messages and social media, the poaching suspects boasted about the animals they illegally slaughtered.” They were accused of killing more than 200 animals including deer, bears, cougars, bobcats and a squirrel.

In 2010, California mountain lion P-15 was found decapitated, with all four paws severed and removed. Regrettably, after a long investigation, an arrest was never made. Mountain lions in California face threats that include habitat loss and degradation, conflicts with humans, roadkill, kitten orphaning, genetic isolation, wildfires, drought, and poisons. Coupled with these threats, poaching may potentially result in localized extinctions.

Take action to stop wildlife crime by learning your state’s wildlife laws and regulations. Be aware of the dates of hunting seasons and the legal limits on trapping.

Wildlife officers are employed throughout each state to respond to wildlife crimes. Report any suspicious activity or information to your state wildlife agency. This handy chart provides contact information for all 50 states.

In California, where actions against mountain lions are severely restricted, contact the California Department of Fish and Wildlife’s hotline for reporting wildlife crimes. Call: 1-888-334-CALTIP (888 334-2258) to reach a dispatcher who can send a local wildlife officer to investigate.

Even if you do not witness the act itself, you never know what investigation may be ongoing in an area. Your tip could make a difference in apprehending a wildlife criminal!

The Mountain Lion Foundation, the California Wildlife Officers Association, and The Oakland Zoo are conducting a social media campaign to thank the nation’s wildlife officers for the work they do to protect our native species. Please, take a photo of yourself and post on social media with the hashtag #IStandWithWildlifeOfficers. Every bit of gratitude is valuable.

Here are some things you can say in your post:

THANK YOU…
– For protecting wild animals from poachers.
– For patrolling in wildlands, towns, cities, and ports.
– For calmly resolving conflicts with wild animals.
– For preserving habitat and safeguarding ecosystems.
– For providing people with accurate information.
– For enforcing wildlife laws in the face of danger.
– For caring for people and the wild animals we respect.

Allies for the Wild Cats of Arizona

Allies for the Wild Cats of Arizona

Trophy hunting and trapping are hobbies that are struggling to justify themselves in today’s age of empathy, education, and conservation awareness. Despite Arizona voters’ disdain for animal cruelty, such practices are still wreaking havoc on the wild cats of the Grand Canyon State. That’s why the Mountain Lion Foundation (MLF) is partnering with Arizonans for Wildlife (AFW) to put an end to these senseless acts of cruelty once and for all. For 10 days MLF employees will be helping AFW gather signatures for a proposed November 2018 ballot measure that would ban the trophy hunting and trapping of all wild cat species within the state, including mountain lions, bobcats, jaguars, ocelots, and lynx.

Though Arizonans feel strongly about inhumane trapping practices, voting to ban the use of steel-jawed leghold traps, body-crushing traps, and snares on public land by an overwhelming majority in 1994, such devices are still used on private land (with cage traps being used on public land). Arizona currently has no limits on the number of bobcats that can be killed each year – over 4,000 bobcats have been killed on average each year for the past five years.

Trapping poses a serious and unnecessarily barbaric threat to all wildlife. As they’re indiscriminate and aren’t tailored to catch just one species, leghold traps and snares result in an inordinate amount of bycatch, which includes both endangered species like the jaguar and ocelot and domestic animals such as dogs. Arizona requires that trappers check their traps only once a day, which is plenty of time for a caught animal to sustain serious injuries to its limbs and teeth while attempting to chew through the trap/snare or even their own leg,or suffer from exposure and dehydration.

Trophy hunting exacerbates the pressures wild cat species face. Mountain lions and bobcats are usually hunted through hounding, which is currently permitted by the Arizona Game and Fish Department. Hounding involves the use of a guide with a pack of GPS-collared dogs that track, chase, and corner their query until the “hunter” follows the dogs to their location and shoots the cat at point-blank range.

Hounding is a dangerous activity for both wild cats and trained dogs. Cats don’t have the running endurance that dogs do and may turn around to fight instead of continuing to flee, leading to injuries to both parties. The heat stress put on animals during high-speed chases under the Arizona sun is serious and needless. Pursuit of endangered species like jaguars and ocelots is prohibited under federal law, but hounds can and will chase and harass any wild cat they find.

Besides the abject cruelty imposed upon wild cats, management of their populations through trapping and trophy hunting is not scientifically sound and has farther-reaching impacts than many realize. The killing of adult female mountain lions usually leads to the orphaning of 1-3 cubs that can’t fend for themselves or take down their own prey until they’re about 12 months old, with many remaining with their mothers until 2 years of age. Killing adult male cats opens territory for young males to move into; individuals that will kill any kittens they come across in an attempt to breed with their mothers.

Several extensive studies also show that killing mountain lions and bobcats only increases human-wildlife conflicts. The young, experienced males that move into a slain adult male’s previous habitat are more likely to engage in conflict with livestock and/or humans, though this is a rare occurrence considering the amount of humans and livestock that continue to encroach upon wild cat habitat. According to the most recent and widely accepted science, the best way to manage predators is with nonlethal methods that discourage or disable said predators from coming into contact with livestock and domestic animals.

We’re also fighting to save wild cats in Arizona to preserve the innumerable benefits they offer to native ecosystems. Top predators like mountain lions, jaguars, ocelots, lynx, and bobcats exist to provide a balance to the great quantities of herbivores (animals like deer, antelope, rodents, and hares) that populate the landscape. If predators didn’t exist, herbivore populations would rise exponentially until they eat themselves out of a home, which would devastate Arizona’s native wildlife communities that rely upon certain types of vegetation to persist. Just look at the reintroduction of wolves into Yellowstone National Park and the effect that had on various ecoregions where aspen stands overgrazed by elk began to regrow again, altering the hydrology of rivers and streams and restoring natural processes that had been absent for decades!

The presence of mountain lions has a similar regulatory effect that contributes to all levels of Arizonan ecosystems. Leftover mountain lion kills (primarily deer carcasses) attract the most scavenger species ever documented and subsequently provide food for other animals like black bears, California condors, eagles, and coyotes, not to mention the litany of invertebrates, fungi, and microscopic organisms that break down organic matter. This all eventually leads to the return of organic nutrients into soil, a critically important cycle vital to the health and growth of plants.

Wild cats are an essential component of the Arizonan landscape and must be managed humanely. Arguments in favor of trophy hunting and trapping have no scientific or ethical base to stand on, whereas our understanding of the importance of wild cats to native ecosystems is only increasing with research and study.

Mountain lions, bobcats, jaguars, lynx, and ocelots have a right to life without the danger of being pursued, trapped, snared, or shot inhumanely. Will you speak for our wild cats and help ensure their protection in Arizona?

Eastern Cougars Removed from Endangered Species List

Eastern Cougars Removed from Endangered Species List

On Monday, January 23, 2018 the U.S. Fish and Wildlife Service (USFWS) announcedthe official removal of the Eastern cougar from the Federal List of Threatened and Endangered Wildlife. The delisting will take effect February 22, 2018.When the Service first declared in 2011 that the eastern cougar was extinct, taxonomists replied that the subspecies never existed. The fact that the Service holds that “the eastern cougar listing cannot be used as a method to protect other cougars” demonstrates a serious flaw in Federal policy affecting species which have been intentionally extirpated across vast areas, damaging human and environmental health, but are not protected because they exist in a sustainable population somewhere else, far across the country.

In 2016, 73 conservation organizations submitted a letter to the USFWS stating that the problem with a decision to delist based on extinction is that no scientific evidence exists that the cougars which once ranged the East are different than other cougars throughout North America. The Service’s insistence that the cougar is extinct and therefore subject to delisting is a spurious argument that cannot be substantiated given the most up-to-date DNA analyses. It is a poor excuse for delisting given that cougars in the Eastern United States continue to meet all of the qualifications for protection under the Endangered Species Act.

“The USFWS cannot declare extinct a cougar subspecies our best science now understands never existed,” said Cougar Rewilding Foundation president, Christopher Spatz in 2016. “The USFWS needs to develop a federal recovery plan for the entire historic range of the North American cougar including the eastern U.S.”

Questions of Taxonomy

Currently, the puma species native to the western hemisphere taxonomically is named Puma concolor (also known as cougar, mountain lion, and panther). Listed as an endangered species in 1973, Puma concolor couguar, the eastern cougar, was just one of 32 subspecies described in 1946. However, genetic research in the 1990s determined there were just six subspecies, including the one that is widely distributed across North America, Puma concolor cougar.

In 2011 the USFWS opened comments on removing the Eastern Cougar from the Endangered Species List. The 2011 USFWS review acknowledges that the 1946 taxonomy of the eastern cougar is flawed. Modern research cannot distinguish between the thousands of cougars living throughout the western U.S. and the rare historic specimens tested east of the Mississippi River. Cougar biologists now generally agree there is a single North American subspecies.

Threats to Recolonization

“This is a simple case of a broadly-dispersed North American subspecies moving to recover its historic range east of the prairie states,” said Lynn Cullens of the Mountain Lion Foundation. “The big cats face no fewer threats than when they were originally listed. Federal action should include, not remove, protections for animals seeking territory within the former range.”

Photo of Cougar Rewilding Foundation ReportPuma concolor has been extirpated from the U.S. east of the Missouri River and north of Florida.
Recolonization has been characterized by cougars dispersing from prairie states into the Midwest for a generation, with rare evidence of the cats roaming as far afield as the Michigan Upper Peninsula, Kentucky and even Connecticut.

“The Midwest has been a cougar graveyard for 25 years,” said Spatz, “Females and wild kittens have not been documented east of the Missouri River.”

Potential for Protection

Cougars need federal protection under the Endangered Species Act (ESA) across their entire historic range. Cougars within their extirpated range meet all of the qualifications for protection under the Endangered Species Act. These include “(A) the present or threatened destruction, modification, or curtailment of the species’ habitat or range, (B) overutilization for commercial, recreational, scientific, or educational purposes, and (D) the inadequacy of existing regulatory mechanisms through all of the North American puma’s historic, extirpated range.” (Assessment of Species Status, ESA Section 4).

Designation of Eastern cougars as a Distinct Population Segment (DPS) is consistent with the intent of Congress in establishing the classification (61 Fed. Reg. 4722, 2/7/1996). The cougars are “distinct” as defined by USFWS since they are geographically isolated from breeding populations elsewhere in the United States. Second, the puma’s former range east of the Mississippi River and north of Florida presents a significant gap.

Adding to the complexity of the puma recovery effort is the fact that the endangered panther of Florida – until Monday, January 23 listed as a subspecies under the Endangered Species Act – shares the primary genetic makeup of the rest of the U.S. population. In a press release, the USFWS stated that “The Service’s removal of the eastern cougar from the endangered species list does not affect the status of the Florida panther, a separate cougar subspecies listed as endangered, and all other cougars that may be found in Florida, which are protected under a “similarity of appearance” designation to aid in protection of the Florida panther.”

“As the lone surviving cougar population in the East,” said Cullens, “the panther’s federal recovery plan, including reintroductions, is critical to recovery across the southeastern U.S., and the panther should remain fully protected by future USFWS decisions.”

The Value of Cougars

A 2016 scientific paper gave a strong boost to the human value of a federal recovery plan for cougars when it pointed out that deer in the U.S. (the cat’s main prey) cause 1.2 million deer-vehicle collisions annually, incurring $1.66 billion in damages, 29,000 injuries, and over 200 deaths. As many as 20 human deaths could be avoided annually if mountain lions were restored to the East.

And mountain lions contribute to the viability of other species and the environment generally. In 2017 Mark Elbroch published research showing that mountain lions contribute to over 3.3 million pounds of carrion to scavengers within North & South American ecosystems every day — that’s half a million pounds more than the amount of beef McDonald’s serves nationwide. 39 different bird & mammal species in the study area fed on kills left by mountain lions, representing an astounding 15% of local wildlife.Common visitors included usual suspects such as red foxes, but also extended to animals like chickadees, deer mice, and even flying squirrels. Myriad invertebrates, fungi, and bacteria that benefit from carcasses as well. Additionally, all that decomposing organic matter returns essential nutrients and elements to soil so that plants may take them up and start the nutrient cycle anew.

“Pumas are one of the most important ecosystem regulators we have,” notes Greg Costello of Wildlands Network in 2016. “When people see the economic and safety value of big carnivores doing their natural work, we’ll all benefit.”

Repercussions

Unfortunately, the delisting may enable individual states greater latitude to kill mountain lions as they re-establish populations in the East. Nebraska, with a recently established mountain lion population of less than 60 statewide, recently expressed its intention to reopen a hunt season on the big cats in 2018. Illinoisis the only state East of the Rockies (other than Florida) that has outlawed killing mountain lions without a state issued permit.

“We can’t rely on a shooting gallery of state laws that encourage everything from unenforced protections to ‘kill on sight’ to no policy at all,” notes Cullens. “State laws are real obstacles, sure as bullets, and cougars don’t see borders.”

When there’s a fire, where do the wild things go?

 

When there’s a fire, where do the wild things go?

Natural disturbances, such as fires, are regular components of all ecosystems and are important for ecosystem health. While the effects of these disruptions may be temporary on an ecological time scale, fires can significantly impact both humans and wildlife by displacing individuals and devastating habitat and homes.Behavior of wildlife in response to natural disturbances will differ based on the type and severity of the event, as well as the species of animal. Some animals will flee, some will fly away, others will burrow underground to escape the disturbance, and inevitably, some will die. Displaced wildlife, those that have lost their homes, will temporarily seek out food and shelter in non-affected areas, including both rural and urban areas.

With fires raging in Napa County, human encounters with displaced wildlife are imminent. Below are some recommendations for responding to displaced wildlife after a natural disturbance.

Wildlife that live in fire-prone ecosystems have evolved alongside fires and will use their keen senses (such as hearing, smell, and sight) to escape fire. The U.S. Fish & Wildlife Service reports that it is uncommon for large mammals to die in wildfires and do not need help escaping fire. However, habitat devastation by fire can lead to temporary displacement of animals, including mountain lions, bobcats, bears, and coyotes.

If you live near a fire, you may notice deer and other animals coming through your yard. Deer were seen seeking refuge in the backyards of residential areas in Burbank and surrounding areas during the fires in Southern California, and coyotes were spotted running down the hills, away from the flames.

The most vulnerable individuals in a fire are young animals who are still dependent on their mothers, as they may get lost if they are separated from them in a fire. We received the video below from a firefighter who recently came across the 3 mountain lion kittens on his way to fight a large forest fire in Northern California. He did not see the mother, however, she was likely nearby. Mother mountain lions leave their kittens when they go to hunt. As the kittens were not injured in any way, he behaved appropriately by quietly observing them and allowing them to pass undisturbed.

Video of Kittens Recently Seen by a Firefighter

In 2005 a mountain lion kitten was rescued from the Butte Fire, and in 2012 a bear cub with burnt paws was rescued from the Mustang Complex Fire in Idaho. California Department of Fish and Wildlife (CDFW) intercepted the kitten, and Idaho Fish and Game the bear, and both were treated for their wounds.

Stories like this are highly unusual, as wildlife can generally detect fires early enough to flee. For young animals that are still dependent on their mothers, becoming separated during a fire can be life threatening. Luckily, these two were rescued, rehabilitated, and re-released! If you come across injured wildlife, do not approach them. Contact your local wildlife agencies and report the incident.

The best thing for displaced wildlife is to pass through and move on to natural habitat with minimal human interaction. Feeding wildlife, such as deer, can provide a false sense of available resources and can result in them sticking around, which can attract predators to your property. To protect yourself and your pets, do NOT attempt to take selfies with wild animals. Be sure to keep all pets indoors and livestock in secure enclosures with a roof during this time. Mountain lions, coyotes, and bobcats will be stressed and in search of food until they, and their prey, can return home to their natural habitats.

If you do encounter a mountain lion, make yourself appear as large as possible and make as much noise as possible. Pick up small children and keep eye contact and slowly create distance between yourself and the mountain lion. If you are attacked, fight back and especially protect your neck and throat. Use branches, rocks, purses and your own hands, legs, or whatever you have to protect yourself. Your goal is to convince the mountain lion that you are a threat, not prey.

For help holding or reporting displaced or injured animals, contact local authorities, such as the animal control office or your local wildlife rehabilitation centers.

Trail Cameras – Location is Everything!

Trail Cameras – Location is Everything!

Our camera team gives careful consideration to where we place cameras in the field to best capture the most wildlife movement. Believe it or not, it’s a bit of an art to get the best coverage for the best results.When you’re working with an array of cameras, as the Cosumnes River Preserve lion camera team is, you have a few things to consider:

  • The size of the area
  • Access to the area
  • Human impact to the area
  • What wildlife is already known to be in the area
  • Where wildlife may be most likely to walk, known as wildlife travel corridors. (This can include game trails, roads and levees.)
  • What kind of wildlife you’re after

And nothing is written in stone. Cameras can always be moved depending on what kind of results you’re getting. It’s a fine balance when you’re working with a limited number of cameras as the rule of thumb when you’re doing this kind of camera trapping is consistency and patience. It will only take one lion walking by one of our cameras to be able to document an historical event – the first confirmed lion sighting on the Preserve captured on camera.

camera on treeCurrently, the team has eleven cameras deployed on the Preserve. Ten of those belong to the Mountain Lion Foundation, on loan for this lion study through a generous grant from the Sacramento Zoo. We’re using Browning Strike Force Extreme Model BTC-7FHD-PX trail cameras. It’s a good camera and gives us the results we want most of the time. We get good day shots and night shots are usually good although they can be blurry depending on how fast the animal is moving.

Adjustments can be made as to the photo quality – higher pixels means bigger photos. We usually use a standard 4 GB SD card for our camera checks. The bigger the photos, the larger the SD cards we’d need, and if the camera is in a high movement wildlife area, we’d need to check the camera more frequently, several times a week, so that the SD card doesn’t fill up, causing you to miss that mountain lion!

Other things we consider carefully are camera direction, height and angle. Once you’ve got an area that you know is a wildlife travel area, you have to pick an object to mount the camera on. On the Preserve, it’s usually an oak tree though several of our cameras are mounted on posts that have been installed by the Preserve. We always look for a north-facing mount, as that usually gives the best exposure throughout the day, with the sun never directly shining on the camera. Direct sun on a camera causes images to wash out, meaning you’re missing important wildlife movement. Next pick for direction would be a northwest mount, so that the camera is still not getting direct sun, and won’t get direct light from the west either, hopefully.

In our experience, an east-facing mount is totally washed out during sunrise and other times during the morning when there’s direct sun. The same goes for a direct west-facing mount during sunset hours. A south-facing mount can get sun all day long as well and can mean that you miss a lot of good shots. In some of the deeply wooded old oak forests, you can play around with the direction, as long as you test it and know your camera won’t get direct sun during the day.

We mount the cameras at least 5 feet high and this is because the Preserve floods. There are many thoughts as to camera height, some folks mount at 30 inches or so, which is a great height to get more eye-level shots of deer and mountain lions. But the Preserve floods almost every year. The higher we mount the cameras, the less chance they’ll be flooded out in the winter months. We’ve had several camera locations at about 4 feet high that went completely underwater during past winters! Using a shim can give you the best angle on a higher mount, casting the camera view a bit downward to better capture the passing wildlife.

Mountain Lion Dance Camera Test!The most important thing of all! Once you’ve picked a location, mounted a camera and got the batteries and SD card in, test, test, test! We let the camera arm and then one of our crew volunteers goes out in front of the camera to ‘walk like a mountain lion’ to make sure where camera locations will pick up a wildlife movement effectively. If the angle is a bit off, we adjust. And we format the SD cards in the field and test each one, each time on each camera to minimize the possibility of field malfunctions between camera checks.

With solid support from the Cosumnes River Preserve staff, our lion crew works hard in the field every week to make sure our cameras are operating at best capacity and are located in the most effective locations. Because it’s not about perfection, it’s about making sure we’re giving the study the best chance to find a lion.

The Bureau of Land Management initiated a mountain lion study on the Cosumnes River Preserve in collaboration with the California Department Fish and Wildlife in 2014. Currently, the study is being carried out by an all-volunteer crew of dedicated individuals who receive support and oversight from the Bureau of Land Management. The Sacramento Zoo has awarded a grant to the Mountain Lion Foundation which has allowed the Foundation to purchase and loan ten trail cameras to the Preserve to help carry out this study. The goal is to find and document a mountain lion on the Cosumnes River Preserve.

Who’s Scat is That?

Who’s Scat is That?

Being out on the Preserve, walking where wildlife walks, the camera crew comes across a lot of scat. Scat provides important information about what wildlife is in the area, what these animals are eating and what kinds of resources are available. The thing to know about all scat is that it comes in many forms, colors and sizes and identifying scat can be challenging! Often scat can seem definitely distinctive and best guesses can be correct. But the only real ways to know which scat belongs to who if identification seems a close call, is if you see the animal defecate or by collecting the scat and checking it’s DNA.

Of course we’re particularly interested in mountain lion scat and the camera crew carries a scat collection kit in our go pack so if we come across scat that is questionable – large, thick, tubular segments about 1 inch in diameter or more, or one long piece with blunt ends and some scratch marks nearby, for instance – we’ll be able to scoop it up for DNA analysis to determine if it is indeed mountain lion scat.

We also always carry a camera and a 6-inch ruler. When photographing scat, we place the ruler next to the scat and take several pictures from different angles before moving the scat. Scale is extremely important as identifying scat under the best of circumstances can be challenging considering the wide range of factors that are involved. Also a wider photo of the scat and it’s surroundings can help with identification – is it in the middle of a road, off to the side, next to a tree, near the water, are there scratch marks nearby?

Other animals on the Preserve produce large and variable scats, all inviting closer inspection to learn more about life on the Preserve. And diet can change how scat looks for every species so there are a lot of variables to consider out there!

Canids, or canines, like coyotes and foxes have diverse diets that can change with seasons and resource availability. Different diets will change the appearance of their scat. While canids do best with a significant amount of meat in their diets, they also supplement that diet with fruits, berries and other plant materials.

Felids, or felines, such as mountain lions and bobcats are obligate carnivores, meaning they absolutely need a diet of meat to survive. Scat of predators can look white or very light in color, and this can be from high calcium content, indicating the predator ate a fair amount of bone recently.

mountain lion scatMountain lion scat can be anywhere from 6 to 15 inches long and be about an inch or more in diameter. The scat can either be segmented or be one solid piece and segments are blunt-ended but there may be one end that is more pointed. You won’t find any fruit or berry seeds, but there will be hair and bone and maybe some grass. You might find this scat in the middle of a road or path or deposited off to the side. Sometimes, but not always, there will be a ‘scrape’ next to the scat pile, as the lion attempted to cover or mark the scat.

A Wet Year for Lions on the Preserve

 

A Wet Year for Lions on the Preserve

As the season warms up and everything gets drier, there will be a lot more walking out to the remote cameras as driving increases the fire danger. Our dedicated camera team is ready to employ foot power in the hopes of getting a mountain lion on a trail camera in the next few weeks on the Preserve.Our last camera check took all day as we were scouting out former camera locations to see if they are still underwater. Due to the historically wet rain season we’ve just had, it has taken a lot longer to deploy all our cameras back out onto the locations we use because they’ve been underwater much later into the season.

Tower pump roadOne of our most remote cameras is still inaccessible by vehicle or foot and if you need a boat to get to the location, you’re quite unlikely to see a lion floating by. While lions are known to swim, they’re not water babies and will do so generally to escape danger, get to another area of territory, or pursue food or a mate.

Unusually wet years like the one we’ve just had, require all the resident wildlife to adapt and use different resources and habitat for food and cover. Areas wildlife typically uses may be underwater or otherwise inaccessible due to the flooding. This also means that lions following prey and looking for dispersal routes might move differently, not just in the Valley, but possibly in the Sierra as the lower snow elevation would shift wildlife movement in the mountains as well.

Twin pumpsFor the other ten cameras we have deployed, we’re just about to hang the rubber boots up! The water is definitely receding and soon we anticipate that pathways will be dry enough to walk in regular boots. At some of the cameras that still have water close by, we see distinct tracks of coyotes, bobcats, river otters, raccoons and deer. We’ve not seen anything that can distinctly be identified as lion tracks near our cameras besides the area where we placed the carcass cameras.

As we approach each camera location we quietly observe the area for tracks, scat, scratch and other disturbance that could mean a large predator. In this way we’re ensuring a two-fold surveillance method of our camera sites – the physical activity that may be taking place, and what critters actually walk by the trail cameras.

We’re also looking ahead to the Sierra snow melt as the increased runoff from last winter’s dense snow pack could bring a new flood event, which would again create different wildlife travel patterns and require that the wildlife on the Preserve adapt to finding food and shelter on a wetter landscape.

We will have to see how the coming snow melt affects our study efforts!

So You Think You Saw a Mountain Lion?

So You Think You Saw a Mountain Lion?

Many people come back from hikes or drives certain they’ve seen a mountain lion. While lions are elusive and mainly avoid people, they do show up sunning on rocks, as an exciting and unexpected sight on a walk out in nature, or as a brief glimpse dashing across a road or highway.

But many folks mistake bobcats and even domestic cats for lions. In the adrenaline-filled moment when you think you’re seeing a lion, we can forget to look for the most distinctive details that will tell you whether the feline you’re seeing is a lion or not.

Here’s some ways to tell if you may be looking at a mountain lion.

Mountain lions are big. They can weigh anywhere from 75 pounds (a young female) to 200 pounds (a full-grown male.) When you think you’re seeing a lion, try to get a sense of how tall the animal is compared to the trees and vegetation behind the animal.

Mountain lions have a long, heavy tail. This is perhaps their most defining identifying characteristic. The tail of a mountain lion can be 1/3 its body length. Used for balance and rudder-like direction changes when chasing prey, it’s thick and muscular with a dark tip. Bobcats have a distinctive stub tail and even large domestic cats have smaller tails that don’t compare with the powerful back appendage of a lion!

Mountain lions are usually tawny in color with no stripes or markings. Their kittens however, are born with spots to help them blend in with the surrounding terrain. Kittens lose these spots as they grow. By around 2 months old, their spots start to fade and by one year old, their spots have faded significantly.

Safety First

If you think you’re seeing a mountain lion, first and foremost take careful steps to stay safe – appear large and loud, maintain eye contact, pick up small children and back away slowly, giving the cat an avenue for escape.

If you are seeing what you think is a mountain lion in a non-threatening situation, such as from a car or in the distance, walking or running away from you or appearing across a river or other natural barrier, don’t ever approach them but try and get a photograph so you can confirm your sighting later!

Seeing a mountain lion in the wild is a rare privilege and you’d be among the relatively few people who’ve actually seen these big cats in their native home.


The Bureau of Land Management initiated a mountain lion study on the Cosumnes River Preserve in collaboration with the California Department of Fish and Wildlife in 2014. The study is currently being carried forward by an all-volunteer crew of dedicated individuals with continued support and oversight from the Bureau of Land Management. The Sacramento Zoo has awarded a grant to the Mountain Lion Foundation which has allowed the Foundation to purchase and loan ten trail cameras to the Preserve to help carry out this study. The goal is to find and document a mountain lion on the Cosumnes River Preserve.

P-45 the Mountain Lion – UPDATE!

P-45 the Mountain Lion – UPDATE!

Over Thanksgiving weekend 2016, a rancher north of Malibu, CA lost 11 alpacas to depredation and P-45 stood accused of the deed. The Mountain Lion Foundation’s 12/04/2016 article tells the story here.P-45 continues to be known and loved by many as one of the few mountain lions who survive in the Santa Monica mountains despite encroaching roadways and ranchettes with livestock and pets that increasingly pop up in his dining room, the territory he calls home. The issuance of a depredation permit to kill P-45 sparked outrage and emotions ran high as many people fought to save this beloved lion. In the end, the rancher left the depredation permit unfulfilled and P-45 alive, while agreeing to let the Mountain Lion Foundation build lion-proof pens on the property to protect the 15 remaining alpacas.

UPDATE

In early December 2016, the Mountain Lion Foundation worked on the rancher’s property to erect 4 lion-proof pens that would keep both her alpacas and P-45 safe from further depredation. The Mountain Lion Foundation pens are 10×10 in size, inexpensive and generally not subject to County permitting because that size is considered a temporary building structure.

The November 30 ‘Living with Mountain Lions’ workshop in Agoura Hills drew close to 300 people and the Mountain Lion Foundation gave out over 100 copies of ‘How to Build a Pen.’ Because so many people expressed interest in building their own pens after the workshop and associated pen build, materials were sold out throughout the Los Angeles area. Fred Hull, the Mountain Lion Foundation’s pen build specialist, had to rent a big truck in Sacramento and pick up the materials for the four 10×10 pens at a Home Depot in Bakersfield!

Lion-proof pens can usually be constructed within a few hours with a small crew of 4 to 8 people. The pens built for the rancher in Malibu are meant specifically to keep mountain lions out. Since lions often attack from above, a sturdy roof was used, one that will hold the weight of a lion and with small enough chain link holes so lion paws won’t get caught in the fencing. Depending on the type of predators in the area, such as coyotes or other digging animals, a skirting or foundation may be needed around the pen to prevent animals from digging underneath the fencing.

To date, P-45 continues to patrol his territory and the rancher has had no more depredation occur on her property. The National Park Service will continue to monitor P-45’s movement through the GPS collar he wears and provide information about his activity. In the meantime, awareness is growing that the most successful way to live with lions like P-45 is for ranchers to protect their livestock and for pet-owners to keep pets inside and on leashes and provide access to lion-proof areas if pets must be outside.

P-45’s story is not over. As a breeeding-age male mountain lion he is invaluable to the survival of the small population of lions that continues to call the Santa Monica mountains their home. It is our responsibility to keep him and all lions safe, along with the livestock and pets who live in lion country. “Everywhere we study them in California, they are in serious danger. The future looks grim for them unless we find a way to better resolve the conflicts that can arise between them and domestic animals.” said Mountain Lion Foundation executive director Lynn Cullens, quoted in the New York Times on December 2, 2016.

So far, P-45’s story is a win-win for the lion and the rancher. Because the rancher has been willing to work with alternative strategies such as lion-proof pens, P-45 is safe for now. The Mountain Lion Foundation is grateful to the rancher for allowing the pen builds on her property to demonstrate that lion-proof pens can work. We’ll continue to encourage others in the Malibu hills and in lion country everywhere to build their own pens, making it more difficult for P-45 and other lions to find a meal among livestock, encouraging them to move on in search of more suitable prey like deer.

P-45’s plight was followed by concerned citizens across the country and has been covered in a number of media sources including the New York Times, Los Angeles Times, Chicago Tribune, The Mercury News, and most recently, the February 2017 issue of The New Yorker magazine.

Protecting both livestock and mountain lions and their habitat is not only possible, it’s essential. It’s up to us to share the landscape and to leave room for the lions who live there.
