1 Invasive Species Monitoring Aquatic and Riparian Effectiveness Monitoring Program (AREMP) Peter Gruendike

2 AREMP Overview Assess watershed condition status and trend in 6 th field watersheds Monitor the effectiveness of the Northwest Forest Plans Aquatic Conservation Strategy in maintaining and restoring watershed condition

3 Study Design 250 randomly selected watersheds Minimum of 25% federal ownership

4 Study Design 250 randomly selected watersheds Minimum of 25% federal ownership

5 Field Data Collection Channel morphology Bankfull width, depth, sinuosity, gradient Habitat characteristics Wood and pool frequency, residual pool depth, substrate size Biological characteristics Amphibians, benthic invertebrates

6 Invasive Species Monitoring Invasive species identified as a critical threat to National Forests Opportunity for spatial distribution information and possible early detection

7 Species of Concern Experts from Oregon State Univ and Portland State Univ helped choose 23 species of primary concern. Based on three criteria: 1. Invades stream or riparian habitats; and 2. On the Oregon Invasive Species Councils 100 most dangerous list or 3. Has a large management program which could benefit from additional spatial distribution knowledge

9 Protocol Development Opportunistic surveys were implemented during 2007 field season Adopted standardized survey protocols for 2008 field season

10 Aquatic Methods Plants - Each stream reach is surveyed for invasive aquatic plants Animals - Benthic macroinvertebrate samples are used to detect presence of invasive snails, mussels, and crayfish.

11 Terrestrial Methods Plants- Six time constrained searches are performed in the riparian area Animals- During large wood surveys, the site is examined for the presence of feral swine (digouts, feces, tracks)

12 Documentation Field crews collect spatial information, photographs, and specimens Photographs and specimens are verified by experts

13 Results In 2008, AREMP field crews surveyed 167 sites in 31 unique watersheds Himalayan blackberry was found at 16 sites in 7 watersheds Reed Canary Grass found at 2 sites in 1 watershed

14 Challenges Commonly misidentified species - Garlic mustard and Giant Hogweed Funding is uncertain Data sharing among agencies

15 The Future Continue to improve training and ID materials $$$- ~$7,000/year Standardize reporting pathways and data sharing

16 Decontamination Field crews are potential vectors in the spread of invasive species AREMP is committed to good environmental stewardship

17 Decontamination - Field Gear Gear types - waders, boots, nets, sieves, gloves, brushes Method - Scrub at stream, boil at camp Done prior to entering a new 6 th field watershed

18 Decontamination - Vehicles Gear types - Vehicles Method - High pressure car wash Done prior to entering a new 6 th field watershed
