Biweekly report Apr16-30 2024 - Region 4 (North Puget Sound)
Managing Wildlife Populations
Beaver Rehabilitation – Successful Release and Establishment: A Washington Department of Fish and Wildlife biologist from King County (District 12), worked with PAWS Wildlife Rehabilitation Center to identify potential locations for beaver release. In collaboration with Vashon-Maury Island Land Trust, a site was chosen on Vashon-Maury. The land trust has reported that the beaver released there are hanging around the site and appear to be doing great. It is rare to be able to release beaver in suburban/rural areas of King County, which makes this site unique.
Snow Goose Survey: Wildlife Biologists Waddell and Soltysiak conducted the annual snow goose survey. This survey was conducted in a small single engine airplane and encompassed an area from southern British Columbia southward to northern King County. Flocks of snow geese were photographed for later analysis by AI software.
Purple Martin Colony Maintenance: District 12 collaborated with volunteers to maintain the Seattle waterfront purple martin colonies at Duwamish Waterway and Shilshole Bay. Overall, roughly 100 nest gourds were cleaned and maintained for reuse this season (with the bulk of those also used last season). The purple martin is North America’s largest swallow that is a state Species of Greatest Conservation Need under the State Wildlife Action Plan. It is largely dependent on human nest boxes, nest gourds, and other human structures for nesting.
The purple martin is a cavity nesting species that needs snags that are over or adjacent to water to build their nests. Snags are dead or dying trees. Snags are a very specialized and limited habitat type that tends to be very patchy in occurrence. For purple martins, removing a group of snags with cavities that they use can take out an entire local martin colony. Snags are often taken down because they can be a safety hazard, and are also removed to preserve views. Simple management of snags, in the appropriate situation where hazards are not of concern, not only provides habitat, but also great wildlife attraction and watching opportunities.
Sooty Grouse Survey: Westside district staff are in ongoing monitoring surveys for sooty grouse, a harvestable forest grouse species, this month and next.
Common Loon Platform Maintenance and Launch: District 12 maintained platforms on two separate territorial common loon lakes. Loons were observed at both lakes. The common loon is a state listed species (Sensitive) and a Species of Greatest Conservation Need in the State Wildlife Action Plan.
Improving Bat Roosting Habitat in Island and San Juan Counties: Biologist Licence, in collaboration with the Watchable Wildlife Program, Master Hunter Program, Diversity Division, State Parks, Girl Scouts, Bats Northwest, Happy Valley Bats Rehab Center, private citizens/landowners and other partners recently built over 50 multi-chambered bat boxes for distribution to stewards throughout the district.
This group rallied to install nine boxes at Deception Pass State Park. These boxes will provide additional living space for up to 2,250 bats in an area where bat exclusion has occurred over multiple winters in private dwellings nearby. Journalists from the Washington Post and a reporter from the Whidbey News-Times attended the event and conducted interviews.
Many of the additional boxes were donated to homeowners with bats regularly roosting in or near their property and are currently in the process of installing boxes. Fifteen more bat boxes were donated to the San Juan Island Land Bank for mounting and monitoring across San Juan and Orcas islands.
Beach Clean-up Efforts on Whidbey Island: Biologist Licence and master hunters represented Washington Department of Fish and Wildlife to support efforts by the Washington State University Island County Extension Office and Naval Air Station Whidbey to remove litter from beaches with a specific focus on collecting and quantifying plastic shotgun wad debris.
In the past month two separate events took place, one in early April at Windjammer Park in Oak Harbor and the other at Crescent Beach on Earth Day. Combined, volunteers collected hundreds of pounds of litter and well over 1000 shotgun wads.
Island Marble Butterfly Spring Monitoring on San Juan Island: Biologist Licence and Pollinator Specialist Combs initiated another year of island marble butterfly (IMB) monitoring on San Juan Island. This week of monitoring included adult relative abundance transects, detection/no detection surveys in known IMB occurrence areas, as well as egg and larvae monitoring at the Cattle Point, Department of Natural Resources property. Staff members also value this time to communicate and build relationships with local conservation partners. The IMB season appears to be earlier this year than in the past and staff members counted 34 recently laid eggs where in recent history no eggs were counted during this early season survey.
Bat Acoustic Activity Monitoring: Biologist Anderson maintained three solar powered acoustic bat recorders that are running year-round in the district. These are used for various trends in activity – emergence periods, species activity at a site, etc.
Providing Conflict Prevention and Education
Bobcat and Wallabies – Conflict Prevention: Wildlife Conflict Specialist O’Connor responded to a call regarding a depredation to captive wallabies. Upon arriving at the site, O’Connor noted a bobcat in the wallaby pen, jumping out as he approached. O’Connor went through exclusionary needs and other conflict reduction management techniques.
Providing Education and Outreach
Protected Wildlife – Trail Building Concerns: Biologist Anderson met with Seattle Parks and Recreation, as well as a citizens group, regarding a local natural area that has a mountain bike trail proposed and in the process of development. A state protected active Cooper’s hawk nest was located right above the trail. They determined currently there is no conflict because the trail building will be well away from the active nest.
Conducting Business Operations and Policy
Westside Necropsy Training: Wildlife health staff members provided a necropsy training and refresher for staff members for both west and east of the crest. In the west training, one of the specimens acquired was an elk from North Bend that had been spinning and appeared disoriented. Necropsy participants found an injury to the head/base of antler that created an injury, and infection and an abscess on the brain that likely created all the behavioral issues the animal exhibited.
