Since 2005, Huron WMD has been implementing a volunteer-driven, 3-part approach to inventorying and monitoring invasive species. This proposal would allow Huron WMD to attain the funding necessary to support the administration, volunteer stipend, and travel needed to further implement this successful program. Part 1 (Inventory) utilizes volunteers to conduct a comprehensive inventory of all upland vegetation that is >50% invaded and >¼ acre in patch size. Funding for 2008 is necessary to support 1 full-time summer volunteer to inventory the remaining 1,038 acres that have not been mapped and to continue to monitor vegetation response to Early Detection Rapid Response. The remaining unmapped 1,038 acres would be thoroughly inventoried for invasive species. Early Detection Rapid Response would be employed to successfully reduce invasive species on the remaining acreage. Thus far, >7,500 acres of invasive species were identified and mapped. This thorough inventory is 86% complete and is slated for completion with volunteers in 2008 provided adequate funding is available. Part 2 (Early Detection Rapid Response) has been effectively implemented by USFWS staff on the 14,920 acres inventoried by volunteers between 2005 and 2007. Part 3 (Monitoring Control Response with Advanced Technology) involves the use of volunteers to quantify the post-treatment response of invasive species. Following Early Detection Rapid Response, treatment effectiveness is precisely quantified either by re-mapping the treated area with a GPS or by using belt transects to measure vegetation response to treatment. These monitoring techniques have allowed Huron WMD to quantify progress towards reducing invasive species.

Describe the type of work the volunteers performed. (Up to 150 words)
Work is conducted as part of the duties of 2 volunteers; one SCA intern and 1 USFWS volunteer. The volunteers help monitor control response by quantifying the post-treatment response of invasive species. Following Early Detection Rapid Response, volunteers precisely quantify treatment effectiveness either by re-mapping the treated area with a GPS or by using belt transects to measure vegetation response to treatment. These monitoring techniques have allowed Huron WMD to quantify progress towards reducing invasive species and therefore, objectively assess treatment efficacy. In addition, volunteers help archive the following data in the RLGIS weed control database: Control method, growth stage, equipment used, weather, and if chemical – chemicals used; date, rate, and method of application.
Total Number of Volunteers: 2
Total Number of Volunteer Hours: 442
List both new and existing partnerships utilized in this project. (Up to 150 words).
We partnered with the Student Conservation Association to successfully recruit 1 SCA intern. Maps of invasive species infestation and treatment provide visually valid data for presentation to collaborative partners, including the District’s 8 County Weed Boards, 8 County Commissions, and the USFWS’s Private Lands Program. Our excellent relationship with these partners is bolstered thanks to the assistance of volunteers, who make it possible for us to (1) locate and initiate control efforts on new infestations and (2) communicate valid conclusions and interpretations of our control efforts for invasive species to our partners.


Project Results:
Give an overview of the results of the project. Include quantifiable measure of success, such as maps produced, efficacy of control measures, number of sites where invasions were detected early and responded to, number of community contacts, etc. (Up to 250 words).
This year, with assistance from 2 volunteers, a baseline map of vegetative cover was developed in GIS for approximately 1,038 acres. Combined with previous years' efforts, a total of 17,500 acres on 61 Waterfowl Production Areas (WPA) will be mapped. Through this mapping effort, 37 acres of Canada thistle and sow thistle, 6.3 acres of Russian olive, 22.9 acres of Siberian elm, 18.1 acres of eastern red cedar, 0.6 acres of leafy spurge, and 8,170 acres of invasive non-native grasses in patches >1/4 acre have been identified and mapped. In 2008, a new infestation of wormwood was discovered while volunteers were conducting the baseline inventory of our newest WPA. No patches yellow or dalmation toadflax, salt cedar, spotted or Russian knapweed, or purple loosestrife were identified. Thanks to the second phase of this effort (Early Detection Rapid Response), a coordinated response has already resulted in the restoration of 29 acres of Canada thistle and sow thistle to planted natives and all identified leafy spurge infestations have been treated using biological control. Since the inception of volunteer inventory and mapping project, 9.2-acres of Siberian elm, 1 acre of eastern red cedar, and 0.7 acres of Russian olive have been mechanically removed (7.7 acres in 2008). Grazing and prescribed fire were used for the specific objective of suppressing invasive grasses on 4,826 acres. The success of prescribed burns in suppressing invasive grasses was assessed on 928 acres of native prairie under Phase 3 (Monitoring Control Response with Advanced Technology).
