Invasive species are second only to habitat destruction as a threat to biodiversity

• $143 billion/year in U.S. economic impacts.

• Over $82 million/year spent in California.

• Early detection, control, and eradication yields a cost-to-benefit of $17-$34 for every $1 invested.

• 4,600 Western wildland acres/day are lost to invasive plants.

• Over 3,300 non-native plant species have naturalized in the lower 48.

• At least 60 of these species cause major ecological/economic impact.

• San Francisco Bay is one of the most invaded aquatic

ecosystems in the world. As of 2003 at least 167 species

have been introduced and established into its marine and

brackish waters. Today’s # might be closer to 200.

“Early detection is the single most important element in successful and economical

eradication of new weeds before they become permanently

established in new localities.”- 2005 California State Noxious

Weed Action Plan

Goals of BAEDN include:

• Ensure effective detection efforts covering the region

• Garner funds to eradicate priority invaders while still cost-effective

• Increase effectiveness and strategic nature of regional invasive species management

• Involve and train citizen detection partners

• Realize a coordinated system of regional early detection networks across all California

• Seeking additional $$ to realize full scope

What YOU Can Do

1. Report non-native plant occurrences and/or upload entire datasets

to the Calflora database.

2. Join or start a “Weed Watcher” volunteer invasive plant detection

program. Existing programs are run by Golden Gate National

Recreation Area, Point Reyes National Seashore, Marin Municipal

Water District, Audubon Canyon Ranch, and San Pablo Bay

National Wildlife Refuge.

3. Subscribe to the BAEDN partners listserve for BAEDN

announcements.

4. Register your organization as a BAEDN partner.

5. Join a BAEDN working group:

– Priority Weed List Group

– Data mining Group/Mapping Group

– Rapid Response Group

– Training, Protocols, and Methods Group
