14 Reed Canary Grass Control And Succession to Wetland Forest and Meadow Three districts on Upper Miss participating in FWS inter-region study on rcg

15 Study Questions –Rcg adjacent to floodplain forest: effect of seed rain following rcg eradication –Rcg in understory of forest: effect of seed rain following rcg eradication –Rcg-dominated meadow: success of reseeding after eradicating all vegetation –Native-dominated meadow: ability of native species to prevent rcg growth following rcg eradication.

16 Fall Determined management units - Set up monitoring wells and gauges -Collected soil samples -Collected seedbank samples in meadows

17 Spring/Summer Marked vegetation sampling plots -Sampled plots pre- treatment and peak biomass -Set up and monitored seed traps in forest units -Contracted herbicide treatment -High water issues

18 Collect seedbank samples in forest units Continue monitoring vegetation plots, wells, seed traps Treat all sites a second time Prepare for reseeding 2009 Field Season

19 Veg Ad Hoc’s Pool 3 Vegetation Sampling 20 crews 10 agencies Sampled between Red Wing, MN and Hastings, MN

20 57 vegetated sites 227 NOAQVG sites (includes 15 too deep to rake) 15 sites on land or inaccessible 13 species submersed vegetation 4 species emergent vegetation 2 species rooted floating-leaved Preliminary results

21 Comparison to previous sampling efforts
