MCP Field Notes: North Columbia Herd.

Looking out across the section of the Columbia Mountains I explored within the home range of the North Columbia Caribou herd.

The town of Revelstoke, British Columbia sits on the banks of the Columbia River. North of town, on both banks of the reservoir created by the impounded Columbia lives the North Columbia caribou herd. This herd has been fairing better in the past several years than many of the herds further south. The reasons for this appear to include a collection of issues including habitat protections, limits on recreational impacts from snowmobiling and helicopter ski opporations and a drastic reduction in moose populations (through human hunting) which has lead to a natural decline in wolf populations and in turn less pressure on caribou. This herd has also been the focus of a program to pen some of the herd's pregnant females during the spring and early summer. The females and their calves which were born in the protection of the pen are released in the midsummer where they rejoin the rest of the caribou in the wild. This project is in its second year (Learn more about it at Revelstoke Caribou Rearing in the Wild). I spent three days in the heart of their range for this herd in the mountains northwest of Revelstoke.

Numerous sets of fresh caribou tracks in the area told me I was in the right spot. Pictured is the hind foot of a bull caribou. Caribou are the only native North American hoofed mammal to regularly show dewclaws (the marks behind the main cleaves, feral pigs found in many places, though none in caribou habitat, also often register their dewclaws), though they show up more regularly in the fronts than hinds.

Early one morning, close to first light, I caught my first glimpse of a mountain caribou, a bull with antlers in velvet. Female caribou also have antlers, though smaller than the males, another unique feature of this species.

The subalpine landscape that caribou appear to prefer is one made of dense forests and wet meadows. This is a species that is definitely NOT afraid to get its feet wet.

The older tracks of a grizzly bear warned me that these creatures might be in the area. I spotted a mom and cub in the morning twilight on the day after I spotted the caribou. They didn’t spot me as they crossed an opening in the forest but also didn’t linger long enough for me to capture a photo of them. Though intrigued, I choose not to follow them to see if I might get another chance to see them. A little ways on I discovered the fresh tracks of a bull moose and calf heading into the same section of forest. An interesting story might have unfolded between these mothers and children of two of North America’s most ornery large mammals. I left this one as another one of the many mysteries that these dark forests hold.

The mosquitos and black flies were atrocious.

Mountain Caribou Project: Darkwoods Conservation Area

The South Selkirks herd is the last group of mountain caribou that still range back and forth across the international border between British Columbia and Washington and Idaho. Just north of the border Canadian Highway 3 crosses the Selkirk mountains over Kootenay Pass, where occasionally caribou are spotted by passing motorists, in Stagleap Provincial Park.

North of Stagleap, the Nature Conservancy of Canada has acquired a large parcel of land with the intention of preserving and restoring vital habitat for this herd of mountain caribou--the Darkwoods Conservation Area. However, these mountains are far from pristine--both the provincial lands and the Darkwoods Conservation Area are crisscrossed with forestry roads, and clearcuts of all sizes and ages. In many drainages, it is only the upper ends of the basin that have been spared cutting at one point or another. The Nature Conservancy of Canada purchased a large tract of land that had been previously managed for timber production. Since its purchase, along with stopping all timber harvest in caribou habitat within the preserve and protecting the existing uncut forest stands, the Nature Conservancy has been deactivating roads in caribou habitat.

Stand of mature western red cedar and western hemlock preserved within the Darkwoods Conservation Area. Late successional stands such as this one are very rare in the southern Selkirks after decades of logging and fires at low and middle elevations in the region.

This landscape creates a maze of fragmented forest types for caribou to navigate while also leading to increased moose and deer populations at higher elevations. Kim Shelton joined me for a week to help search for caribou sign and carry photo equipment on ridiculous buggy bushwacks to several promising remote corners of these mountains. In a week of searching, location after location, where caribou where once abundant, we discovered the tracks and sign of moose, deer, and elk but the only tracks we found of caribou in a week of searching were a set of old tracks close to Kootenay Pass on Highway 3.

Linear features such as this road and power line corridor in the range of the Southern Selkirk herd, often act as routes for wolves, who hunt caribou, and humans, who’s presence can displace caribou, to access mountain caribou habitat.

Wolf tracks along the road running alongside the power line corridor. The province of British Columbia has carried out extensive predator control in this area, killing wolves from three different packs in an attempt to protect the remaining 13 caribou in the South Selkirks herd. These predator control efforts have been extremely contentious amongst various groups involved in caribou conservation.

Porcupine Lake in the Darkwoods Conservation Area. The Nature Conservancy of Canada completely removed a road that had been built into this lake to reduce human access and increase the quality of habitat for caribou in this subalpine basin.

Mountain Caribou Project: The Adventure Begins

Tomorrow I embark on a month of travels through the interior of British Columbia to learn about and photograph the world of mountain caribou. The mountain caribou of British Columbia, Washington, and Idaho are one of the most southern herd of caribou found anywhere on earth and their continued existence is threatened by a myriad of conservation challenges. Follow along here and on my instagram feed to learn more about these beautiful and endangered throwbacks to the Pleistocene. Over the course of the month, besides exploring and photographing in caribou country, I will also be meeting with people involved in caribou conservation and scouting for future trips to the region to fully capture the story of mountain caribou and the wild lands they call home.  Below are a few photos of mine from past trips to mountain caribou country. Many more to follow!

Caribou trail in the Selkirk mountains of southern British Columbia.

Grizzly bear tracks just north of the Washington-British Columbia border. Grizzly bears are also a sensitive species in much of this region. Over the next month I will be exploring and documenting the ecology of caribou and how they interact with the mountains they call home, the other wildlife they share the landscape with, and the people that live, work, and play in caribou country.

Maligne Lake in Jasper National Park. Mountain caribou populations are being closely monitored in even large wilderness landscapes such as in the Canadian Rockies.

Trailing Black Bears in the North Cascades

This spring I spent a week out in the field with several colleagues from Cybertracker Conservation honing our tracking and trailing skills following the trails of black bears on the western slope of the North Cascades. I put together a brief video describing the art of trailing and documenting some of what we discovered on our adventures in the temperate rainforest. 

Interested in learning to trail bears and other wildlife? I offer custom classes in a wide variety of tracking subjects, including wildlife trailing.

A week at home in the Methow Valley.

With a bit more than a week at home between expeditions this June, besides catching up on emails and the odds and ends of keeping "the rest of my life" rolling, I managed to get a few outings done in my backyard here in the Methow Valley. These included a day of climbing with friends, a solo traverse of some of the local high country, retrieving remote camera's I had out for a bit over a month while I was gone, and an evening in a makeshift blind at a local beaver pond close to the Methow River. Here are a few of the images from my week....

Wildlife In the Methow Valley, Viewed Remotely

This winter I have been running remote cameras of mine, and assisting the Ray Robertson and the United States Forest Service with the deployment of several others in various locations around the Methow Valley here in north central Washington. Remote cameras are considered a non-invasive research method, as they provide a means to monitor wildlife without having to handle or even directly observe them. Remote cameras greatly increases the amount of time we can monitor a location and also reduces our impact on the species we are studying by limiting the amount of time we are actually in the field in their habitat. Remote cameras, if set thoughtfully can also provide beautiful images that both document various species of wildlife while also illustrating their relationship to their environment and each other. Here is some of what we have been finding this winter here on the eastern slope of the North Cascades.

Mule deer, such as these two are one of the most conspicuous species of wildlife in the Methow Valley and show up in camera sets in many low elevation camera traps around the valley.

A young mountain lion explores the same location where the deer from the previous image had visited earlier. Other images from this camera captured both this lion and its mother in the same location.

An adult mountain lion sniffs at the buried remains of a deer which had been cached about a week before by either himself or possibly another lion that uses this area. After inspecting the area briefly, this lion moved on without retrieving anything of the buried carcass.

Golden eagle and black-billed magpie feeding on the remains of this same carcass which had been excavated by a bobcat several days earlier. In this image I had the camera looking down on the sight from an overhanging tree branch.

A group of river otters bounds along the banks of the Methow River. I set this camera at a location where I had found sign of a number of species of wildlife and the set also captured images of mountain lion, deer and beaver.

A photo of myself. As part of setting a camera trap I will trigger the camera and then inspect the images it is capturing to make sure the focal area of the camera is capturing the area I am interested in. Behind me is the remains of a mule deer that had been killed and consumed by wolves several weeks earlier. Here I am using the carcass as an attractant to draw carnivores into the range of the camera.

A pair of coyotes inspecting the carcass. They scent marked the area and then left without scavenging on the carcass.

This bobcat was more interested in getting a meal out of the deer carcass!

Even after many other visitors, a hungry wolf returned to the carcass to feed on the bones and hide that remained.

A mule deer buck captured on a Forest Service camera set by Ray Robertson and I in a location we had found tracks of wolves.

A daytime image from the same camera. The short ears and stocky muzzle of this animal identify it as a wolf.

Several weeks later, this coyote was captured at the same location, identified by its more slender build and narrow snout.

Remote camera set targeting wolves and mountain lions along a game trail. For this camera set I am anticipating the travel route of these species through my interpretation of their tracks and knowledge of how they typically travel through this particular location. I expect that I will also get photos of mule deer, and coyotes as well as possibly bobcats and red squirrels. Will keep you posted on how this one turns out…its out there right now!

Productive remote camera traps aren't just created by sticking a camera up just anywhere in the woods. It requires careful observation of tracks and signs, knowledge of the target species biology and ecology, how to use natural and imported attractants, as well as specific tricks on how to get the most out of the equipment you are using in the field. Click here to learn more about remote cameras and other non-invasive wildlife research methods. David Moskowitz provides custom trainings on many of these methods and consulting services for projects looking to employ them effectively and efficiently in the field.

Wildlife Tracking Certifications In Europe

This fall Casey McFarland, Mark Elbroch and myself delivered wildlife tracking workshops and certifications in the United Kingdom, Slovakia, Germany and the Netherlands.

Footprints from a stone marten (Martes foina) found under a bridge in eastern Germany. Note that a Euro 2 cent peice is the same size as a US penny.

While Europe and North America share many similar species, there are a number of behaviors typical in Animals in each location which are not common in similar species in the other. The Great Spotted woodpecker, similar to the North American Hairy woodpecker, collects and breaks open pine and other conifer cones for the seeds within, in a mannor not typically observed in North America.

Numerous certificates where awarded in all 4 countries we visited including everyone who participated in the evaluation in Germany, pictured here. Congratulations to everyone. We will be finding an online home for the names and certification levels of folks certified in Europe through Cybertracker Conservation shortly. Stay tuned!

Afternoon with a Monk Seal

Endangered Hawaiian Monk Seals on Kauai's Napali Coast

During my recent trip to the Napali Coast in Hawaii I camped out on the Kalalau beach with Darcy Ottey. One afternoon, after a walk in the jungle, we returned to the beach to discover an endangered Hawaiian monk seal had hauled out on the beach. We watched it for several hours before it returned to the ocean during an evening downpour. A few weeks later the New York Times ran a really interesting article, "Who would kill a monk seal?" by Jon Mooallem which explores the complex history and current situation around the conservation of this species, endemic to the Hawaiian island chain.

Participant Lloyd Murray inspects wildlife sign on the edge of the Muddy River.

Apparently the world can be overwhelming, even for creatures that spend much of their time lounging on the beach in Hawaii.

While very graceful in the water, monk seals move awkwardly on land where they are vulnerable to harassment or worse from humans.

Once in the water, monk seals can move more easily.

Track and Sign Certification in the Swan Valley, Montana with Northwest Connections

Northwest Connections is an innovative organization which runs a variety of biological monitoring, conservation, and educational programs all revolving around the unique and wild landscape of the Swan Valley in northwestern Montana where they are based. In April, I delivered a Cybertracker Conservation Track and Sign Certification Event for them. A very talented group endured challenging field conditions (including about 5 inches of fresh snow Saturday night and Sunday!) and everyone in the group earned a Certificate. My friend and colleague Emily Gibson came along to take some photographs and I am grateful to her for sharing a number of the images for this post!

We started the evaluation on the Northwest Connections campus on the Swan River. Here I am explaining how the evaluation process works at the start of the first day.

The evaluation included a number of questions about the remains of a white-tailed deer which had been consumed by wolves.

Inspecting a leg bone from the deer which had been partially consumed by the wolves revealed the bone marrow which offers clues to the health of the deer at the time it died.

Heavy snow Saturday night and Sunday morning called for desperate measures. Here Adam Lieberg, Conservation Program Coordinator for Northwest Connections, uses a broom to brush snow off of sign we had found during our scouting for the evaluation.

Mike points out one of the questions on the evaluation about a mountain lion scat and scrape, created by a scent marking behavior of the large cat, found along the same game trail as the claw marks from the previous photo.

We took refuge under a bridge for a few questions on the snowy Sunday.

A blade of grass points to the tip of a mink track found under the bridge.

Every question on the evaluation is discussed thoroughly after all the participants have submitted their answers. Here we are discussing the sign left behind by an elk which used its incisors to peel bark on a small tree and then rub its head against the tree, a common scent marking behavior of elk.

The shredded bark has all been peeled upwards due to the fact that elk only have lower incisors. Numerous hairs from the elk got stuck in the ragged bark and sticky pitch of the tree.

Congratulations to everyone who participated in the evaluation. In this particularly talented group of wildlife trackers, everyone earned a Level 2 certificate or higher!

Level 2 Certificates Awarded: Jim Quinn, Trenton Harper, Scott Tomson, Andrea Stephens

Level 3 Certificates Awarded: Cassie March, Luke Lamar, Lara Arvidson, Mike Stevenson, Alissa Anderson, Rebekah Rafferty

The Remains of an Owl and Other Finds from the Field

This weekend was the 6th weekend of 9 for the year-long Wildlife Tracking Intensive I teach for Wilderness Awareness School. This month we spent Saturday searching for signs of large carnivores and other creatures in the dense rainforests of the Middle Fork of the Snoqualmie River on the western slope of the Cascades. Among other things we discovered the following tracks and signs:

• Feeeding and scent marking signs of black bears
• Scent marking signs of a mountain lion
• Beaver feeding and dam building activity
• Black-tailed deer and elk sign including antler rubs, trails, tracks, scats and feeding sign

Teaching assistant Dan Gusset and student Erin Campbell inspect the bite mark of a black bear found on a small tree along a game trail. Such marks are commonly produced by scent marking bears whom also claw and rub such trees in efforts to attach their scent to tree for other bears to find.

Douglas Cowan inspects a pika hay mound found under a bridge along the Snoqualmie River. Pika typically live at higher elevations in the Cascades but here were making use of the large boulders laid down at the base of the bridge which mimic higher elevation talus fields. Pika’s collect vegetation in mounds for later consumption in the rocks where they live.

Trever Ose examines some elk hair on an antler rub. Antler rubs are an important scent marking behavior of bull elk associated with the breeding season. After abraiding the bark of the tree with his antlers, the elk will then rub the tree with his face, shoulders and the base of his antlers to attach his scent to the tree. The scent acts as an advertisement to female elk in the area and a challenge to other males.

On Sunday we ventured out to the banks of the Puget Sound where students were quizzed on a wide variety of tracks and signs, including identifying and interpreting the story behind the remains of numerous species of birds we discovered. Tracks and signs we found included:

• Tracks of: racoon, river otter, feral house cat, mink, muskrat, opossum, black rat, deer mouse, shrew, American robin, sparrow, black-crowned night heron, teal.
• River otter scent marking sign
• Pellets from several species of owls containing vole remains
• Northern harrier pellets
• The remains of a barn owl, a short-eared owl, several snow geese, a female pheasant, and several species of ducks most of which appeared to have been predated by areal predators.

On Sunday, besides tracks and signs, the birding was quite good. We observed four snowy owls, a short-eared owl, numerous Northern harriers and other hawks, dunlin, yellow-legs, pintails, widgeons, western meadowlarks, snow geese, trumpeter swans, and many other species.

Feathers from a barn owl (left) and short-eared owl, both found on the edge of a large field filled with vole sign where each owl had likely been hunting when they were killed. The short-eared owl remains where found scattered in the brush bellow some trees in a location where a larger bird, such as a great-horned owl or bald eagle might perch to consume a meal. The barn owl feathers where found below another tree on the ground and was also likely consumed by a raptor.

The class under a particularly large Sitka spruce on the bank of the Middle Fork of the Snoqualmie River. The large amount of reddish debris at the base of the tree is the result of a feeding Douglas squirrel. Such a midden is created when the squirrel consumes conifer cones from a favored perch and discards the remains onto the forest floor below the perch.

Track and Sign Certification in southern Texas

In mid January, I made my first trip ever to Texas where I joined Texas State Wildlife Biologist and Cybertracker Evaluator Jonah Evans to deliver a Track and Sign Certification event for Urban Biologists from the Texas Parks and Wildlife Department (TPWD) in southern Texas. Jonah is also the author of an excellent Iphone App Tracking Guide and manages a website with a large collection of well organized track and sign photographs.

Track and Sign Evaluator and Texas Parks and Wildlife Biologist Jonah Evans leads a discussion about the tracks left by several coyotes traveling on the shore of Laguna Atascosa in southern Texas.

The wetlands and thickets of this part of Texas are a birding mecca, with over half of all the species of birds which can be found in the continental United States making their way through the region over the course of the year. Besides bird life, the area is home to a wide variety of mammal species including oceolots, a very rare species in the United States as well as feral pigs and a variety of other introduced exotic species.

Grand Canyon Wildlife, Birds, and Tracks

Wildlife and signs of wild animals abound along the Colorado River in the Grand Canyon. The silty banks of the river hold the tracks of many species large and small while birds, from tiny canyon wrens to California Condors can be spotted on the water, in the brush or soaring above the canyon walls. Here is a little bit of what I found on my recent float trip down the river.

Animal Tracks in the Grand Canyon

Footprints of a wild animals were abundant along the banks of the Colorado river. Here are a bunch of wildlife tracks I took while on the river along with a few clues on how to tell what they are!

 Grand Canyon Birds

Though I am not much of a birder I amassed a species list of about 35 birds during my November-December trip down the Canyon. The abundance and diversity of birds definately increased towards the end of the trip. Here are a few I managed to snap a photo of.

Ross’s x Snow goose hybrid. We saw a single pair on the river. They had probably stopped during their southern fall migration.

Canyon Wrens were one of the most common birds to see or hear along much of the river. Their beatiful lyrical song echoeing off the canyon walls was one of the most amazing sounds on the river. Grand Canyon, Arizona.

Grand Canyon Mammals

While footprints revealed the presence of a great many more species of mammals than we actually had live sightings of our party saw bighorn sheep on several occasions and had some notable interactions with ringtails. Perhaps most unusual was the discovery of a ringtail in one of our party's tent when he retired for the evening!

Another Look at Northern Flying Squirrel Tracks

Perhaps because of the forest habitat they occupy and tendency not to travel for long distances on the the ground, clear footprints of the northern flying squirrel (Glaucomys sabrinus) have rarely been detected in the wild, or at least rarely documented. I personally have never definitively identified this species's tracks in any substrate other than loose snow. As such producing reliable illustrations for the tracks of flying squirrels is challenging. In writing my field guide I had less direct field data on this species than any other mammal species whose tracks are illustrated in the book. The illustrations, measurements and description of northern flying squirrel tracks in Wildlife of the Pacific Northwest are based on the following data sources:

• Snow tracks found in conjunction with definitive flying squirrel sign, typically the landing mark at the end of a glide.
• A plaster cast of a number of tracks of a single flying squirrel which was collected for me by Kevin Mack,  at PAWS in Lynwood, WA from a captive female northern flying squirrel which was being rehabilitated for release there.
• Sketches, notes and photographs I took from study skins of northern flying squirrels from the Mammalogy Collection at the Burke Museum of Natural History and Culture at the University of Washington.
• Photographs and illustrations of the tracks and signs of this species from other wildlife tracking literature, (all included in the bibliography of my field guide).

In the spring of 2012, while delivering a Tracking Certification with Dr. Mark Elbroch, author of a number of books on wildlife tracks in North America, Mark offered me the feedback that his most recent research on this topic suggests that his original depiction of northern flying squirrel feet in Mammal Tracks: A Guide to North American Species, along with my own are inaccurate. In Mark Elbroch's most recent book, co-authored with Jonah Evans and Michael Kresky, Field Guide to Animal Tracks and Scats of California, the authors present a revised illustration of the tracks of this species based on their inspection of study skins and footprints collected from sooted track plates. Following this conversation, I revisiting my own original research materials, as well as the literature and made a follow up trip back to the Burke Museum, where I reexamined study skins as well as a fresh specimen which was waiting to be processed.

As Elbroch, Evans, and Kresky depict, northern flying squirrels do have a distinctive, though subtle, anatomical feature in their hind feet which is unique among squirrels in the Pacific Northwest and California. Toe number 5, the outside toe, is longer than is typical for squirrels or other rodents. Inspecting the actual feet of a frozen flying squirrel as well as numerous study skins, this toe, while not quite as long as the central three toes is nearly so, and visually apears in a similar plane to them, while toe 1 is distinctly shorter and falls on a seperate plane. This feature is present in the tracks collected from the sooted track plate which is published in Elbroch, Evans and Kresky. While the only clear tracks in a natural substrate I have been able to examine, those of the captive animal's which were collected in sand, do not show this characteristic as distinctively as it appears in sooted track plates and on the actual feet themselves, I suspect that it would likely often be apparent in tracks in natural substrates.  This characteristic, not currently illustrated or described in Wildlife of the Pacific Northwest, could be used to distinguish the tracks of this species from the related Douglas (Tamiasciurus douglasii) and red squirrels (Tamiasciurus hudsonicus) which share the Pacific Northwest and much of the rest of North America with northern flying squirrels.

Because there is such limited data on this topic, I have included photographs and sketches from my research for review by others. Similarly, if others have photographs, sketches or access to northern flying squirrel's I would love to see their material and explore this subject further. Thanks much to Jeff Bradley at the Burke Museum, and the Burke Museum in general, as well as Mark Elbroch for their assistance with this topic.

Wildlife Tracking in the Tatra Mountains of Slovakia

In late September, the Slovak Wildlife Society hosted a weekend Wildlife Tracking Workshop in Liptovský Mikuláš, a village in the Tatra Mountains of Slovakia. The Slovak Wildlife Society is involved with a range of conservation projects focusing primarily on the region's large carnivores including working to prevent negative interactions between wolves and bears with humans. Here are a few of the highlights from my trip to the region and the class with a collection of very fine European naturalists and wildlife trackers.

My initial impressions of northern Slovakia during my train ride through the country was that it reminded me much of the state of Montana, with the notable addition of castles.

16-20: The aroma of rotting salmon

A black bear carries its prize back to shore for a late afternoon meal.

Spent 4 of the last 5 nights out in the field, attaining a sense of oneness with the river, the tides, the migrating salmon, the moss and lichen cloaked trees of the rainforest, the bloodthirsty blackflies, and the ever present aroma of rotting fish carcasses--the good life. Several interesting encounters with wolves  which I'm sure will make it into the book.Flying south tomorrow and home the day after. Now that all the field work is completed, I reckon I'll be chained to my computer for the next month and half writing. Don't think I'll be posting daily updates.

Day 5: Puppies!

Three curious wolf pups in a wet meadow.

Doug and I walked into a area where he has found wolves fishing for salmon in past years to see if there were fish running in the stream yet. Apparently we weren't the only one's curious about it!

Huge western red ceder stump set amidst second growth forest of planted Douglas firs. Note that the original nurse log that the ceder tree started growing on in still under the stump, attesting to the volume of biomass in the previous ancient forest and the literally centuries it took to create the structural diversity so important to many Old growth obligate species.

Despite decades of conservation efforts, Clayoquot Sound, a UNESCO Biosphere Reserve,  faces numerous severe threats to its ecological integrity including clear cut logging of roadless old growth forests, industrial Atlantic salmon fish farms, and proposed open-pit copper mining.

Wolf Tracking in the Salmon River Mountains, Idaho

The landscape, typical of the mountains of central Idaho shows conifer forests, dominated by lodgepole pine (Pinus contorta) in various stages of regeneration after naturally occuring fires. Interspersed are large wet and dry meadow systems.

Don Taves inspects the trail of a wolf trotting down a dirt road.

The right front foot of a large wolf. The toes have splayed widely and the claws of each digit have dug in deeply, including in the reduced inside toe due to the fast speed of this animal. The bounding trail of this wolf was adjacent to the trail of two fleeing mule deer indicating a pursuit (apparently unsuccessful for the wolf).

A pine marten (Martes americana) peers down from a safe perch.

Sandhill crane (Grus canadensis) in flight. Cranes breed and rear young in the vast wet meadow systems of central Idaho.
