MCP: Finding Mountain Caribou in Summer

After 28 days searching for mountain caribou, exploring the places they call home, or have recently disappeared from, here is a summary of some of what I discovered:

• If you are in mountain caribou habitat, there is a pretty good chance you are either getting harassed by mosquitos, enduring a cold wet summer storm, or both.

• There are a lot of long logging roads in western Canada and if you are going to find mountain caribou, it will likely be all the way at the end of them, where clear cuts give way to the last stands of uncut forest at the tops of mountain valley and along ridge-lines.

The end of 88 km (55 miles) of logging roads in the Seymour River watershed. Here avalanche chutes mix with recent clearcuts of inland temperate rainforest and remnant patches of old cedar forests where caribou still linger.

• The threats to mountain caribou are varied across their range and even huge national parks and provincial preserves are not necessarily effective by themselves to protect these animals.

The Tonquin Valley, accessible only by trail, and completely contained within Jasper National Park, is home to the largest remaining concentration of caribou in the park but even here caribou numbers are declining rapidly.

• Climate change is here now.The effects of climate change are readily apparent already in many places where mountain caribou live.

Mount Edith Cavell, a famous peak and glacier in Jasper National Park and area still occupied by caribou. Like mountain environments around the globe, the glaciers in the Canadian Rockies and Columbia mountains are retreating quickly. Most of the glaciers I observed while in the field had no accumulation zone anymore, leaving them as large blocks of ice melting in the warming climate.

• Doing nothing is doing something, but perhaps not the something we want to do. Without landscape level conservation measures and ongoing agressive management of caribou and other species of wildlife caribou are ecologically connected to, mountain caribou will likely disappear very soon from much of their current range, as they already have from many places they recently existed. Much of this management is controversial and/or highly invasive to the wildlife and the humans who live, work, and play in caribou habitat including things like culling moose and deer populations, killing entire packs of wolves, landscape scale cessation of logging and or oil and gas mining activity which is the basis of the regional economy, restrictions on winter recreation activities, also an important regional revenue stream.

Moose tracks in the mud in the southern Selkirks. On my first trip to the area in 2009 I found only caribou sign in the area. On this trip all I could find was moose, elk and deer. Burgeoning moose and deer populations across much of the range of mountain caribou have lead to increased predation on caribou from wolves, mountain lions, and other carnivores whose populations are tied to moose and deer.

The survival of mountain caribou is not at all assured across much of their range. In the weeks and months to come I will continue to be researching this topic, planning future trips back to caribou country, collaborating with conservation organizations to help get the word out about this pressing conservation topic. Stay tuned!

MCP Field Notes: Cariboo Mountains

Looking across the Rocky Mountain Trench at the Hart Mountains from the Cariboo Mountains. The Fraser River oxbows through the trench which divides these two mountain ranges.

I made my furthest trip north for the project to explore a small corner of the Cariboo Mountains, just south of the town of Prince George, British Columbia. In these mountains and across the Rocky Mountain Trench, in the Hart Ranges, caribou numbers are fairing a bit better than further south. However, with lots of room to spread out in the summer across multiple vast mountain ranges, finding them this time of year proved to be a challenge. During the summer mountain caribou disperse across the subalpine forests of these mountains in order to reduce the chance of being detected by predators. This strategy apparently also works effective for avoiding curious humans as well!

Treeline meadows and ponds where I searched for caribou in the area.

The wet meadow system was miles from the closes road or trail. With huge amounts of inaccessible forested landscapes to spread out in, mountain caribou can seemingly disappear into these mountains.

MCP: Logging in Mountain Caribou Habitat

The timber industry has been the backbone of the economy in most of the interior of British Columbia for several generations. Industrial scale logging is also the primary source of the majority of challenges facing Mountain caribou. Because of this, sorting out how to protect caribou habitat while at the same time dealing with the demands of the very powerful timber industry (and modern civilization for that matter) for lumber has been an especially challenging task in attempts to conserve and restore caribou populations.

How well this has been done varies in different locations around the province. A few thing are clear. Mountain caribou depend on low and middle elevation old growth forests for early winter habitat, and high elevation old growth for winter habitat. Clearcuts and early stages of forest regeneration are prime habitat for moose and deer which attract attention from wolves and mountain lions who then prey on caribou more often in landscapes with a large logging footprint in them. Logging roads become access routes for humans on snowmobile in the winter to areas that are sensitive for caribou who are easily displaced by human recreation activities in the winter. A large amount of habitat has been set aside for mountain caribou which has curtailed logging in some areas and road use restrictions have been put in place as well. However, logging of both old growth and second growth forests continue in mountain caribou habitat in some places.

Mountain caribou conservation has put stresses on both in terms of restrictions on logging as well as the heliski and snowmobile recreation which are big business in the area.

British Columbia is the last place in the Pacific Northwest with significant stands of old growth forest still slatted for logging, both on the coast and in the interior. Conservation groups have used caribou protection as a tool to curtail logging in these ancient forests, much the spotted owl was used in the United States several decades ago—imperfectly in both cases. With caribou populations continueing to decline in much of their range logging interests have started looking at having these restrictions lifted once the caribou disappear from an area while conservation groups are looking at what might be the next lever for protecting whats left of this unique inland temperate rainforest.

Industrial scale logging which employs large machinery to cut and remove logs often leaves a devastated appearing landscape behind, including lots of wood cut and left on the ground, to expensive to transport out for the value of what can be made from it.

Kim Shelton takes in the grandeur of a remnant stand of old growth western red cedar close to Trout Lake British Columbia. How we as a society place value on forests and trees such as these is highly varied. Whether places such as this, and the animals such as mountain caribou whom depend on them, will continue to exist in any significant quantity for future generations to argue about seems tenuous at the moment.

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.

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!

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.
