SALIX AssOCIATEs FEBRUARY 1997 <br /> (2 week frequency appropriate?) <br /> Bullfrog Surveys. Visual surveys for bullfrogs will be conducted concurrently with visual surveys for <br /> turtles. <br /> Fence monitoring. The condition of the fence around the turtle habitat areas will be monitored <br /> annually by volunteers. Openings in the fence large enough to permit passage of people or predators <br /> such as cats and dogs will be reported to PWM. <br /> Water quality monitoring. (MEDIUM) The water of the pond and of Spring Creek upstream of the <br /> pond will be tested every 5 years beginning in 1997 to determine if water quality is being degraded by <br /> pollutants that could be harmful to the turtle population. The analysis in 1997 will provide baseline <br /> data for comparison with future analyses. <br /> (City already funded to do water quality testing? Check with Deborah Evans.) <br /> Vegetation monitoring - plantings. (LOW) Plantings for habitat improvement will be monitored by <br /> volunteers to assure good survival. Planted stock will be examined for vigor, drought stress and animal <br /> damage (e.g., beavers). Monitoring will occur every 2 weeks during the first and second summers <br /> following planting from early June to early September. The site will also be monitored for invasive <br /> vegetation <br /> Vegetation monitoring - invasive plants. (MEDIUM) The entire turtle preserve will be monitored <br /> every 2 years for invasive plants that could impact habitat quality. Monitoring will be done by a <br /> qualified botanist or trained volunteer. Target species will include purple loosestrife (Lythrum <br /> salicaria), Eurasian water-milfoil (Myriophyllum spicatum), Himalayan blackberry (Rubus discolor), <br /> Scot's broom (Cytisus scoparius). Designated turtle nesting habitat areas will be monitored for <br /> invading woody vegetation. In addition these areas will be checked to make sure that herbaceous <br /> vegetation is mowed often enough to prevent excessive shading. <br /> • <br /> Other species? <br /> Destination for reports. All monitoring projects should be recorded on a data sheet, listing date, <br /> persons involved, tasks accomplished, and other observations. All reports shoud be kept on file at the <br /> PWM office. <br /> IX.
