About Jen Poirier

Jennifer is part of the Strategic Habitat Conservation Group where she provides her expertise to the Pacific Lamprey Conservation Initiative, U.S. v. Oregon Production Advisory Committee, and aquatic invasive species invasive species
An invasive species is any plant or animal that has spread or been introduced into a new area where they are, or could, cause harm to the environment, economy, or human, animal, or plant health. Their unwelcome presence can destroy ecosystems and cost millions of dollars.

prevention efforts. Her duties include working collaboratively with Conservation Initiative partners (i.e., States, Tribes, Federal agencies, watershed councils) developing Regional Implementation Plans, and identifying funding sources for projects that support Pacific Lamprey conservation, performing aquatic invasive species monitoring at lower Columbia River National Fish Hatcheries, and conducting training sessions to disseminate new aquatic invasive species management information (e.g. disinfection protocols, AIS identification, reporting protocols, and USFWS Invasive Species Policy guidelines).

Program: Passage and Habitat Assessment

Current Projects:

1. Coordinating activities that support the Pacific Lamprey Conservation Initiative

   a. Leading Pacific Lamprey Regional Management Unit (RMU) meetings.

   b. Working collaboratively with RMU partners to identify specific projects and research needed to address critical threats to lampreys within the region

   c. Working with regional partners to develop Regional Implementation Plans and revise the Pacific Lamprey Risk Assessment

   d. Identifying potential funding sources for high priority conservation actions

   e. Providing technical assistance to identify critical information gaps, research, and conservation needs for Pacific Lamprey and other lamprey species

2. Serving as the assistant Aquatic Invasive Species Coordinator for Oregon

   a. Alternating as a FWS representative on the Oregon Invasive Species Council (OISC)

   b. Conducting aquatic invasive species monitoring at lower Columbia River Basin National Fish Hatcheries using eDNA and visual surveys

   c. Evaluating the effectiveness of a biological control strategy to eradicate non-native Brook Trout at Carson National Fish Hatchery

3. Providing technical assistance to partners, teachers, and natural resource professionals on aquatic invasive species identification, Pacific Lamprey and Pacific Salmon ecology

Past Projects:

1. Developed the Columbia River Aquatic Nuisance Species education trunk

2. Implemented a multi-year radio telemetry study to investigate migration timing and survival of Warm Springs National Fish Hatchery juvenile spring Chinook in the Deschutes Basin.

3. Constructed, installed and maintained half duplex (HDX) and full duplex (FDX) Passive Integrated Transponder (PIT) antennas to monitor fish distribution and movement through natural streams, culverts, fish ladders, and hatchery raceways.

4. Performed large-scale fish salvage effort on lower White Salmon River to mitigate effects of Condit Dam breach and removal.

5. Performed occupancy and mark/recapture sampling in freshwater rivers and streams throughout Oregon to investigate the abundance, distribution, survival, recruitment, movement and life history characteristics of juvenile salmonids and char.

6. Assessed the effects of habitat restoration actions on fish populations and aquatic habitats within sloughs in the lower Columbia River estuary.

7. Monitored trends in abundance and factors limiting production of ESA-listed Chum salmon below Bonneville Dam.

8. Implemented a radio telemetry study to investigate habitat selection, movement among spawning areas, and stream residence timing of adult Chum Salmon in tributaries below Bonneville Dam.


Jennifer spent four years working as a field technician for the Washington Department of Fish and Wildlife and Pacific States Marine Fisheries Commission where she conducted spawning ground surveys on adult salmon and Steelhead populations on lower Columbia River tributaries, coordinated and performed genetic sampling for the Zone 6 tribal fishery, and monitored commercial and sport fisheries (smelt, salmon, sturgeon) on the lower Columbia River. She also spent two summers conducting juvenile and adult salmonid snorkel surveys and stream habitat assessments in the Tillamook and Nooksack River basins for The Wild Salmon Center and Ecotrust, .

YY Male Brook Trout Stocking and Population Monitoring in Tyee Springs

Tyee Springs is located directly upstream of Carson National Fish Hatchery and is home to a thriving population of nonnative Brook Trout. This population has been a hatchery management concern and past attempts at suppressing or eradicating the Brook Trout population have been unsuccessful In...

Reliability of visual surveys and eDNA sampling to detect a new invasion of New Zealand mudsnail

Early detection and monitoring of aquatic invasive species (AIS) are vital in preventing their establishment and reducing their spread in aquatic habitats. The New Zealand mudsnail (NZMS), Potamopyrgus antipodarum, is an invasive aquatic snail that poses a threat to National Fish Hatcheries (...

Pacific Lamprey Conservation Initiative Regional Management Units and Regional Implementation Plans

The Pacific Lamprey Conservation Initiative (PLCI) is a collaborative effort among natural resource agencies and tribes to reduce threats to Pacific Lamprey and promote the implementation of restoration and conservation measures throughout Alaska, California, Oregon, Washington, and Idaho. To...

Aquatic Invasive Species Monitoring at Lower Columbia River Basin National Fish Hatcheries using eDNA and Visual Surveys

National Fish Hatcheries (NFHs) produce fish that provide commercial and recreational fishing opportunities, fulfil tribal trust and mitigation responsibilities and contribute to the recovery of threatened and endangered species. Managing the threat of aquatic invasive species (AIS) is one of...

Feasibility Assessment of Stocking YY Males to Eradicate Nonnative Brook Trout from Tyee Springs

An established population of nonnative Brook Trout resides in Tyee Springs directly upstream from Carson National Fish Hatchery. The potential for Brook Trout to escape from Tyee Springs and enter the hatchery is a concern because the hatchery releases spring Chinook yearlings into the Wind...
