| Short Description |
The objectives of the Aquatic Plant Technical Assistance Program are to: 1. Provide advice on aquatic plant identification, biology, and management to government agencies and the public. 2. Document aquatic plant distribution and habitat through site visits. 3. Assist with evaluating projects supported by Freshwater Aquatic Weed Program grant money. During the 1999 field season, aquatic plant data were gathered at 86 different waterbodies located throughout the state. Several previously unknown populations of non-native invasive aquatic plants were recorded. (Also see abstract below) | |

| Abstract | Long Description |
The objectives of the Aquatic Plant Technical Assistance Program are to: 1. Provide advice on aquatic plant identification, biology, and management to government agencies and the public. 2. Document aquatic plant distribution and habitat through site visits. 3. Assist with evaluating projects supported by Freshwater Aquatic Weed Program grant money. During the 1999 field season, aquatic plant data were gathered at 86 different waterbodies located throughout the state. Several previously unknown populations of non-native invasive aquatic plants were recorded. Myriophyllum spicatum (Eurasian watermilfoil) was found in Palmer Lake, Okanogan County; Black Lake, Pacific County; Marshall Lake, Pend Oreille County; and Drano Lake, Skamania County. Egeria densa (Brazilian elodea) was found for the first time in Loomis Lake, Pacific County. A population of Myriophyllum aquaticum (parrotfeather) was found in Brooks Slough, Wahkiakum County. The emergent species Lysimachia vulgaris (garden loosestrife) was found in the wetlands around Fish Lake, Chelan County and Lake Alice, King County. Lythrum salicaria (purple loosestrife) was previously unknown from Riley Lake in Snohomish County, as was Epilobium hirsutum (hairy willow-herb) at Spearfish Lake, Klickitat County. Also Typha angustifolia (lesser cat-tail) was first noted in Tanwax Lake, Pierce County and Sixteen Lake, Skagit County this year. In addition to routine aquatic plant monitoring, we completed the data collection and analysis for the 2,4-D demonstration project that was started in 1998 in Loon Lake, Stevens County. We also collected biomass data from Long Lake, Kitsap County as part of a study looking at long-term trends in the Egeria densa population. Additional plants for the herbarium collection were gathered, and we provided educational and technical outreach and assisted with projects funded by Freshwater Aquatic Weed Program grant money. |
