Describe Projects Initiated with Follow-Up Funds ($10,000): The ongoing efforts to detect and eliminate invasive threats at Pondicherry needs to continue. Early detection and rapid response by volunteers working with trained staff is the most cost effective way to deal with invasive threats. The refuge has seen a continued and hard to eradicate purple loosestrife infestation at the outlet of Cherry Pond, Cedar Marsh and Hazens Pond and the junction of the rail trail and Route 115A. We need to prevent Purple Loosestrife from expanding from the outlet of Cherry Pond and spreading to Moorhen Marsh or along the Johns River and the Deadwater. The Pondicherry team plans to use herbicide injectors (NH DOT) again in August 2009 as a way to eliminate Japanese Knotweed from Route 115. A monitoring report will be prepared in 2009 to document the effectiveness of herbicide application in 2006, 2007 and 2008 along Route 115. We will need 1,000 loosestrife eating beetles in 2009 for use at Hazens Pond, Cedar Marsh, Cinder Road and the junction of the rail trail and Route 115A. A publication from NH DOT on Best Management Practices for Controlling Invasives along Roads was completed in 2008. This document uses some of the lessons learned at Pondicherry for controlling Japanese knotweed. We anticipate that Balsam Wooly Adelgid will become a bigger problem in 2009 affecting balsam fir stands. We have no practical control methods. We are concerned that the Emerald Ash Borer may appear in the area as early as 2015 from the mid-west and we will continue monitoring for that and the hemlock Wooly Adelgid which is not present yet. Results: Acres Intensive Survey: 184 acres Miles Intensive Survey: 18 miles (roads, rail grades, trails, streams, lakes, openings) Methodology: We used a minimum distance of 33 feet (66 feet total) on both sides of linear searches along roads, trails, and streams. Many searches were conducted more than once and efforts concentrated on searching disturbed areas on foot and shorelines via canoe. Plants Destroyed: Approximately 300 Japanese Knotweed, 81 Spotted Knapweed, 389 Purple Loosestrife, 10 Canada Thistle, and no Morrows Honeysuckle. Invasive Species: 1 insect (Balsam Wooly Adelgid); 7 plants (Purple Loosestrife, Japanese Knotweed, Spotted Knapweed, Coltsfoot, Morrow’s Honeysuckle, Canada Thistle, Sweet Clover)
Total Number of Acres Treated with Follow-up Funding: 2
Total Number of Acres Restored with Follow-up Funding: treatments are ongoing
Total Number of Volunteers Engaged in Treatment and/or Restoration: 12


How has this Project Benefited Invasive Species Management Efforts at Your Station? Pondicherry is an unstaffed station. The dedication & perserverance of the volunteers has allowed us to know the extent of the infestations & provided a means of annual treatments. Japanese knotweed & purple loosestrife are serious threats that require the annual monitoring & treatments provided by the volunteers.
What are some of the Lessons Learned and/or Troubleshooting Points that could be Shared with Others Engaged in Similar Activity?
We did not have success with the original hand-held computers. Our volunteers prefer Garmin GPSMAP 76CS units.
