North Cascades National Park Wildlife Tracking Certification

In mid-June North Cascades Institute hosted the first Wildlife Tracking Certification Event in North Cascades National Park. Besides a diversity of tracks and signs some challenging field conditions including some classic North Cascades rain and multi-element bushwacking/wading added to the experience for myself as the evaluator and for participants! Here are a few of the highlights from the Evaluation.

The right front foot of a mink (Neovison vison) in fine glacial silt found close to the mouth of Thunder Creek.

These tracks of a Douglas squirrel (Tamiasciurus douglasii) were found just down the shore from the mink.

This unusual sign of a beaver (Castor canadensis) in the riparian forest along Thunder Creek stumped many.

Roger Bean, who earned a Level III Track and Sign Certification contemplates the beaver feeding sign during the evaluation.

The weathered track of a black bear (Ursus americanus).

Terry Kem, founder of Deerdance, earned a Level III Cerftication as well on the evaluation, seen here photographing a sign post tree well used by black bears along Thunder Creek.

Moose (Alces alces) are rarely sighted in western portion of the North Cascades, but these pellets indicate one had passed by the Easy Pass Trailhead along the North Cascades Scenic Highway.

Scat from a bushytailed woodrat (left, Neotoma cinerea) and a pika (Ochotona princeps) were both discovered in a large talus field.

Susan Brown, a graduate student in the North Cascades Institutes Masters of Education program, assisted with the evaluation. Pictured here by a powerline pole that had been bitten and rubbed on by black bears.

Congratulations to everyone who participated in the Evaluation. Of 10 participants, 3 Level III , 3 Level II , and one Level I certificates were awarded. For a list of certified trackers in North America click here.

Cybertracker Conservation Track and Sign Certification Event in the Swan Valley, Montana

Congratulations to all 11 folks who participated in the Track and Sign Certification Event in wild Swan Valley of northwestern Montana this past weekend, all of whom earned a certificate through Cybertracker Conservation!


The event was hosted by Northwest Connections in the very quiet town of Condon. It was great getting to know more about this creative and inspiring organizaiton whose mission to "Integrate Science, Education and Community in the Conservation of Rural Working Landscapes". I highly recommend any and all of the various educational opportunities they have to offer and hope to be back there soon! A special thanks also to Nick Sharp, Wildlife Conservation Society Biologist, and Doctoral student at the University of Montana, who organized the event (and put in a stellar performance on the Evaluation!)


Over the course of the two days of the Evaluation, participants were given 70 different questions about tracks and signs discovered in the field. Species varied from voles to grizzly bears and the handiwork of everything from a bushytailed woodrat to a backhoe. Along with covering as diverse a set of tracks and signs as is possible over two days, the evaluation includes questions ranging from very simple (such as a clear deer track) to very challenging (such as interpreting the behavior of an elk which had scraped bark off of the trunk of an aspen with its incisors). For more information on Cybertracker Conservation Wildlife Tracking Evaluation methods click here.

Senior Tracker and Evaluator Mark Elbroch points out some of the finer details of a track during a discussion of one of the questions on the Evaluation

Senior Tracker Brian McConnell, who assisted in delivering the evaluation,  points out one of the questions, marks on an aspen tree to Adam Lieberg, Conservation Program Program Coordinator at Northwest Connections. Adam correctly interpreted them to be made by a black bear which had climbed the tree.

Here are photos of some of the things that were on the Evaluation and the questions about them. All questions are based on actual tracks and signs discovered in the field by evaluators during the Evaluation. After all of the participants have the opportunity to answer each question, the track or sign is discussed as a group and the evaluators carefully explain the correct answer and discuss why it could or could not be various other species, often using illustrations and other resources to help illustrate key features.

What species and which foot? Front and hind tracks of a red fox.

What species, which foot, and what was the sex of this animal? The left hind foot of a female mountain lion.

What species (in regards to the lower tracks)? The front and hind foot of a wolf (above are the track of a whitetailed deer).

What happened to these shrubs? Tim Nelson inspects the work of a buck deer which left these marks on a serviceberry shrub with its antlers the previous fall, a marking behavior associated with courtship and breeding activities.

Who removed the bark from this burl on a lodgepole pine? From left to right, Track and Sign Specialist Matt Nelson, Mark Elbroch, Preston Taylor and Adam Lieberg discuss a contentious question, a burl on a lodgepole pine which had been debarked by a red squirrel.

Who left this track? The weathered footprint of a grizzly bear.

Mark and Jenn Wolfe discuss one of the harder questions on the evaluation, the identity of a jawbone found in the field--in this case a wolf! Mandibles were not in short supply, and the striped skunk and black bear jawbone were also questions on the Evaluation.

Who made this hole? A foraging badger.

Congratulations to everyone who participated and earned a certificate at the event!

Wolf Tracking In Wisconsin

Just home from a week and a half of adventuring in northern Wisconsin where I participated in a collaboration between Teaching Drum Outdoor School and Wilderness Awareness School on Wisconsin Wolf Tracking Expedition, joined by former Wilderness Awareness School Instructor and founder of the Earth Native Wilderness School, David Scott. Teaching Drum hosted the program which was held very close to the School's home base near the town of Three Lakes, Wisconsin.


Despite unseasonably warm conditions on several of the days and a lack of fresh snow for the first half of the class, snow conditions allowed us to peice together some amazing stories about the wolves of the region and the other wildlife that share the North Woods with them.

David Scott and Teaching Drum staff member Chris Bean discuss the home range of the Giant Pine Pack which the class spent several days tracking.

Prior to the start of the program, Teaching Drum founder Tamarack Song took David Scott and I out to visit the folks participating in the rigorous 11 month long Wilderness Guides Program.

The participants in the Wilderness Guides Program invited us into their sleeping shelter, where they are weathering the snow and subzero temperatures of northern Wisconsin in relative comfort.

Do mink (Neovison vison) have webbed feet?

While researching and writing my field guide I encountered various published accounts of the foot structure of mink (Neovison vison). Because of these discrepancies I sought out specimens to examine personally. I examined the feet of 3 recently deceased mink, all from western Washington as well as about a dozen museum skins at the Burke Museum at the University of Washington. All of the green specimins I examined showed mesial webbing on both front and hind feet. Some of the museum skins did as well, while others where dried in such a way so as to make analysis of this impossible. None of the green specimins or museum skins were clearly lacking webbing between toes. The amount of webbing is slightly less than in their larger cousins, river otters (Lutra canadensis) but is none the less quite clear. As is typical with the tracks of most web-footed animals, webbing can be detected in footprints in deep substrates but is often not apparent where substrate is firmer.

The photos of actual feet bellow are from a male mink which was killed by a vehicle in the Snoqualmie River Valley, King County, Washington in 2009.

All four tracks of a mink in a typical loping pattern for the species. In this deep substrate the webbing between the toes has registered. Tracks from along the Snohomish River, Snohomish County, Washington.

Closer view of two tracks (left hind on top of left front) from the same set of tracks as above.

Tracks a small (likely female) mink from along the Yakima River in Kittatas County, Washington, also in a typical loping pattern. In this firmer substrate the mesial webbing has not registered.

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. Learn more about the region and how you can support conservation in the region at the following websites:

Atlantic salmon fish farm in Clayoquot Sound with uncut forest in background. Several rivers with no clearcuts or roads in them are seeing massive declines in salmon numbers due to sea lice and other issues associated with fish farming in the Sound. The smell is overwhelming, far worse than a dairy farm and totally shocking in such a wild setting.

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.
