Information regarding upland species and <br />wildlife can be obtained in VoJume II of this report. The data reported here is comprised <br />of data gathered by various monitoring agencies as well as data from observations during <br />three visits to Trott Brook during October, 1996. <br /> <br />Table 2. <br /> <br />Observed(*) and potential aquatic organisms of the Northfork <br />Development Area, Anoka County, Minnesota, 1982 (Boos, 1995) <br /> <br /> <br />* Snapping turtle <br />Painted turtle <br />Blanding's turtle <br />Spiny softshell <br /> <br />Chelydra serpentina <br />Chrysemys picta <br />Emydoidea blandingii <br />Trionyx spiniferus <br /> <br /> <br />American toad <br /> <br />Bufo americanus <br /> <br />Gray treefrog <br />Striped chorus frog <br />Mink frog <br />*Northem leopard frog <br />Green frog <br />Wood frog <br /> <br />Hyla bersicolor <br />Pseudacris triseriata <br /> <br />Rana septentrional is <br />Rana pipiens <br />Rana clamitans <br /> <br />Rana catesbiana <br /> <br />Table 2 lists various biological organisms other than Insects found in or around <br />the waters of Trott Brook. Table 2 provides data on organisms which could be observed <br />during educational classes or hikes and which could be described on interpretive signs <br />along a trail system near the Brook. These organisms have found sufficient food and <br />shelter to make the brook their habitat. Table 3 lists the benthic macro invertebrates found <br />in Trott Brook on October 15, 1996. <br /> <br />7 <br />
