Jamestown S’Klallam Gathering Steelhead DNA for Database

The Jamestown S’Klallam Tribe wants to know which age class of steelhead is surviving best within the Dungeness River watershed.

While checking smolt traps and conducting spawning ground surveys this spring, the tribe took tail and scale samples from 500 juvenile steelhead in five creeks between Sequim and Port Angeles: Seibert, McDonald, Matriotti, Bell and Jimmycomelately.

“We’re already counting the adults and juveniles every spring and fall, so why not take DNA samples and develop an age database for steelhead?” said natural resources technician Chris Burns.

Tribes sample elk DNA to track population

Wildlife biologists from Stillaguamish, Tulalip and Western Washington University sample DNA from elk scat.

Wildlife biologists from the Stillaguamish and Tulalip tribes are testing a new way to track the population of the Nooksack elk herd using the animals’ scat.

Tribal biologists have partnered with Western Washington University’s Huxley College of the Environment to determine the most efficient way to collect DNA from elk scat. Genetic material can be found in the intestinal mucus coating the pellets. This winter, biologists sampled fresh scat using toothpicks and cotton swabs, submitting the samples to a genetics lab to determine which method is most effective at providing an animal’s unique genotype.

“This is a non-invasive method that does not require collaring animals or helicopter time to survey them,” said Stillaguamish biologist Jennifer Sevigny. (more…)

Lower Elwha Klallam Tribe starts Roosevelt Elk Study

With an interest in the long-term sustainability of elk populations on the north Olympic Peninsula, the Lower Elwha Klallam Tribe has started a three-year research project aimed at gathering baseline data of the elk herds that reside between the Elwha River and Clallam Bay.

The tribe has two key goals: To gather basic ecological information on the Roosevelt elk that live in the Elwha River region prior to deconstruction of the Elwha dams in 2012; And to develop methods for longer-term monitoring of these herds. This will allow the tribe to determine if the elk population is increasing, decreasing, or remaining stable over time.  This study will provide the tribe with information about seasonal elk movement patterns, habitat requirements, and population size and structure.
