1 Dry Creek Red Sesbania Management Program 2004-2010 Administered by Placer RCDAdd Placer RCD Logo and other group logosBy Lizette LongacreNatural Resource Manager
2 Red Sesbania (Sesbania punicea) Facts AKA: rattlebush, scarlet wisteria,Native to South AmericaIntroduced as an ornamentalHigh seed productionGrows/matures fastSeeds toxic to poultry, cattle, sheep, goats and humans“Q” Listed by Ca Dept. of Food and Agriculture
3 Initial Treatment and Funding (2004-2006) Project Funding - Proposition 13 Flood Protection Corridor Program Grant - provided by the CA DWRProject 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 FisheriesProject Management – SAFCA and May & Associates, Inc. provided hands-on project management
4 Project Objectives Improve floodwater conveyance Aid the restoration of natural processesContribute to a statewide effort to control red sesbaniaEliminate a large key source population of red sesbaniaRestore 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 Maintenance Program (2007-2011) Project Management – Placer RCD administrating programSAFCA providing technical supportSuccess Criterion: less than 1% remaining in treatment area
10 Maintenance Funding Stimulus (2010-2011) 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)Add Placer RCD Logo and other group logos
11 2007-2010 Management Highlights Crew of ~13 peopleTwo treatments between June and Oct.- hand removal or application of AquamasterCollect lawn-sized bags of seed podsPhotographs courtesy of Agri-Chemical
12 ResultsContractor met performance criterion by removing 99% of red sesbania from Dry Creek WatershedAll seed pods removed from watershedIncreased effort in high water yearsreduced amount of herbicide but no decrease in removal effort to dateNo of seedlings/year still high, especially in lower watershed
13 Statewide EffortsDry Creek data added to statewide RS mapping effort in 2010Dry Creek watershed identified as heaviest infestation area in stateOther areas of infestation:Churn Creek – Shasta CountyOroville area- downstream into Feather RiverSan Joaquin River - Fresno CountySacramento/Placer Dry Creek project - largest regional management effort in state
14 Lessons LearnedWeed 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 volunteersPartner- Look for other programs that can maximize your programLine 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 sitesseek to have Ag Commissioner’s field crew spot treat identified sitesEngage contractor to treat watershed following prior years’ protocol – two sweepsDistribute postcards to adjacent property ownersRecruit additional funding commitments from partners – new/old
