Managing Wildlife Populations
Sooty Grouse Surveys: Washington Department of Fish and Wildlife (WDFW) wildlife biologists in western Washington are in the second year of testing a survey method for sooty grouse (formerly called blue grouse). The effort involves establishing driving routes in the Cascade and Olympic mountains as well as the Willapa Hills.
The routes include 15 to 30 listening stops where biologists spend time listening for the calling of male sooty grouse during the early morning hours. The survey method is borrowed from Oregon Department of Fish and Wildlife as well as Oregon State University and we thank them for their development of the method and sharing. When fully developed and implemented, the survey will generate sooty grouse population trend estimates that are independent of grouse harvest. To date, Biologists Stephens, Holman, Wickhem, and Bergh, along with Conflict Specialist Aubrey and Cowlitz Wildlife Area Assistant Manager Steveson have conducted eight surveys.
An additional component of the work is to use listening devices called Acoustic Recording Units (ARUs) to better understand the timing of the sooty grouse breeding season. This is important since the survey methodology was developed at lower latitudes in Oregon where breeding timing could be different. The ARUs are placed near calling sooty grouse and left in place for approximately two months. During this time, the device records the calling grouse. With several of the units placed throughout western Washington, in aggregate this information can be used to adjust Oregon’s protocol to Washington’s grouse population. Biologist Holman, Conflict Specialist Aubrey, and Enforcement Officer Tippets placed three units in Cowlitz and Lewis counties.
Glenwood Valley Annual Sandhill Crane Survey: Biologists Wickhem, Bergh, and Ott; Data Manager Blatz, Volunteers Castagnoli, Flick, Steider, L. Robinson, D. Robinson, B. Roe, and J. Roe; staff members from Mount Adams Resource Stewards, and staff members from the U.S. Fish and Wildlife Service joined forces for the annual sandhill crane survey on and around Conboy Lake National Wildlife Refuge.
The Glenwood Valley is one of only a few areas in the state where sandhill cranes nest. Sandhill cranes mate for life and return to the same “territory” each year to mate and raise their colts before migrating south in the fall. For this survey, the groups split up into teams to drive and hike around different crane territories recording all cranes observed and specifically looking for crane nests. Wickhem and her survey partners confirmed three nests and observed a nest exchange (males and females take turns sitting on the nest)!
Townsend’s Ground Squirrel Surveys: In 2023, District 9 staff members visited 130 historic locations of Townsend’s ground squirrels in eastern Klickitat County to determine how many of these sites were still occupied. At a small number of those sites, occupancy was unconfirmed, meaning the surveyors found some signs of squirrels, but could not determine how fresh the signs were and did not see or hear any actual squirrels.
In April 2024, District 9 staff members revisited these sites to confirm if they were occupied or unoccupied. Unfortunately, each of these locations was determined to be unoccupied, but staff members were able to find squirrel colonies in a few new locations that had not been recorded in the past. Townsend’s ground squirrels are a Species of Greatest Conservation Need (SCGN) in Washington and are considered a candidate for state listing.
Mount St. Helens Elk Herd Population Survey: In late March, biologists from Region 5 conducted an aerial survey of the Mount St. Helens elk herd. In addition to the “core” herd area which consists of GMUs 520, 522, 524, 550, and 556 that has historically been surveyed annually or biannually, biologists also surveyed portions of the herd area to the south. The expanded survey area includes portions of GMUs 554, 560, 568, and 572. These areas are generally more difficult to survey because they have fewer clear cuts or other openings that allow observers to detect elk that are present.
Within the “core” GMUs, the same survey units are surveyed from year to year and a sight ability estimate is applied to the data collected. The estimate for the core area was 2,097 elk. This is a 38% increase from the last time this area was surveyed in March 2022 with a total of 1,522 elk. A big thanks to JL Aviation’s Pilot Pete Emmerson for his safe and skillful flying.
Providing Recreation Opportunities
Vandalism in Klickitat County: The restroom at the Turkey Hole Access Area was severely vandalized with graffiti in early April. Vandalism to this extent is unusual and very disappointing for Klickitat County. With two trips and multiple coats of paint, Natural Resources Specialist Celaya was able to make the restroom look respectable again.
Conserving Natural Landscapes
English Ivy Removal: Cowlitz Wildlife Area staff members, with the help of master hunters and Rocky Mountain Elk Foundation volunteers who donated approximately 700 hours of their time over the four days of the project, removed over 26,000 pounds of vegetation (mostly English ivy) from the Mossyrock Unit.
The ivy is well established within the area and surgically removing the ivy without impacting the desirable vegetation is not an option. The first weekend the sun was shining, the temperature was perfect, and the crew removed 11,000 pounds of vegetation. The second week, the weather turned vengeful and kept the crew wet and cold. However, the crew rallied and removed 15,000 pounds of vegetation.
This was tough work, and the wildlife area staff members could not have done this without the volunteer help. Also essential to the success of the project were Rodger and Ramona Wallace. Rodger and Ramona not only saw the possibilities and encouraged wildlife area staff members to embrace the use of volunteers, but they also reached out to their network of volunteers and single handedly organized an army of individuals. Then, to keep morale high, they organized a potluck lunch every day of the project. With the food provided by the volunteers, you can’t beat a meal of elk burgers, German sausages, elk stew, chili, and all of the sides one could want.
Conducting Business Operations and Policy
Chemical Immobilization Training: District biologists, conflict specialists, and enforcement staff members attended chemical immobilization training in Ridgefield. The training is required every five years for staff members who use chemical immobilization drugs.
Chemical immobilization is used when marking or collaring wildlife for research and in conflict situations when an animal may need to be removed from a dangerous situation. The training covered the types of immobilization drugs, the equipment used in immobilizations, different capture situations, and human and animal safety, among other topics. The class was capped off with dart gun practice and immobilizing domestic goats. All of the goats responded well to the drugs, maintained healthy vital signs throughout, and woke up without a problem.
