1 Dry Creek Red Sesbania Management Program By Lizette Longacre Natural Resource Manager Administered by Placer RCD

2 Red Sesbania (Sesbania punicea) Facts  AKA: rattlebush, scarlet wisteria,  Native to South America  Introduced as an ornamental  High seed production  Grows/matures fast  Seeds toxic to poultry, cattle, sheep, goats and humans  “Q” Listed by Ca Dept. of Food and Agriculture

3  Project Funding - Proposition 13 Flood Protection Corridor Program Grant - provided by the CA DWR  Project Oversight – Management Advisory Team: Sacramento and Placer County, City of Sacramento and City of Roseville, SAFCA, Placer County Agricultural Commissioner, California Dept. of Fish and Game, U.S. Fish and Wildlife Service, and NOAA Fisheries  Project Management – SAFCA and May & Associates, Inc. provided hands-on project management Initial Treatment and Funding ( )

4 Project Objectives  Improve floodwater conveyance  Aid the restoration of natural processes  Contribute to a statewide effort to control red sesbania  Eliminate a large key source population of red sesbania  Restore recreational and habitat values along Dry Creek.

5 Baseline Red Sesbania Mapping Approximately 26 linear miles (14 acres) of Red Sesbania were mapped within the 100-square mile watershed boundary

9  Project Management – Placer RCD administrating program –SAFCA providing technical support  Success Criterion: less than 1% remaining in treatment area Maintenance Program ( )

10 Stimulus ( ) City of Sacramento, Parks ( ) County of Sacramento, DWR ( ) Sacramento Area Flood Control Agency ( ) Water Forum ( ) Placer County Planning Dept. - CALFED ( ) Ducks Unlimited (2009) CDFA, Placer Co. WMA grant ( ) County of Placer ( ) City of Roseville ( ) County of Sacramento, Parks (2008) Maintenance Funding

11  Crew of ~13 people  Two treatments between June and Oct.- hand removal or application of Aquamaster  Collect lawn-sized bags of seed pods Photographs courtesy of Agri-Chemical Management Highlights

12 Results  Contractor met performance criterion by removing 99% of red sesbania from Dry Creek Watershed  All seed pods removed from watershed  Increased effort in high water years  reduced amount of herbicide but no decrease in removal effort to date  No of seedlings/year still high, especially in lower watershed

13 Statewide Efforts  Dry Creek data added to statewide RS mapping effort in 2010  Dry Creek watershed identified as heaviest infestation area in state  Other areas of infestation: –Churn Creek – Shasta County –Oroville area- downstream into Feather River –San Joaquin River - Fresno County  Sacramento/Placer Dry Creek project - largest regional management effort in state

14 Lessons Learned  Weed control is a long-term objective; the project should be long term too!  Red sesbania can germinate, grow to 6 feet tall and produce flowers/seeds within 6 weeks  Re-treatments are a MUST!  Don ’ t start something you can ’ t finish

15 Lessons Learned (Continued)  Maximize your funds with efficient use of paid staff partnered with volunteers  Partner- Look for other programs that can maximize your program  Line out your grants so there is no gap in funding

16 Lessons Learned (Continued)  Don ’ t forget the permits (allow 3-6 months minimum for permit processing time).  Restoration (passive or active) following weed control is important.  Keep up to date on similar projects and effectiveness of various techniques.

17 Lessons Learned (Continued)  Document your progress – a picture is worth a thousand words!  Record your successes and failures in project notes.  NEVER GIVE UP!!!

18 Next Steps  Confirm upper watershed infestations –biologist to map identified sites –seek to have Ag Commissioner’s field crew spot treat identified sites  Engage contractor to treat watershed following prior years’ protocol – two sweeps  Distribute postcards to adjacent property owners  Recruit additional funding commitments from partners – new/old
