Herpetelogical Visual Encounter Survey point locations fall along these lines. Contains distance data for the use in a repeatable density analysis: encounters per distance. Herpetological Visual Encounter Survey.
The purposes of this project are 1) to better understand the distribution and abundance of northern leopard frogs on OSMP; 2) to identify best opportunities for habitat restoration to improve habitat conditions for northern leopard frogs; 3) to attain objectives outlined in the Grassland Plan: to increase the percentage of surveyed ponds supporting only native amphibians to 50% and to increase the number of OSMP ponds where northern leopard frogs are present but non-native, invasive American bullfrogs (Lithobates catesbeianus) are absent. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Study routes for amphibian visual encounters survey. Routes are next to streams and pond/lake perimeters.</SPAN></P><P><SPAN>Since 2006, staff have conducted visual encounter surveys in one form or another (VES) to assess amphibian distribution and abundance. OSMP staff monitor wetlands for the presence of native amphibians with a focus on locating sites that support northern leopard frogs (Lithobates pipiens)—a state sensitive species and one that staff specifically manage for as outlined in the Grassland Ecosystem Management Plan (Grassland Plan). The Grassland Plan contains three management objectives related to amphibians: 1) to increase the percentage of surveyed ponds supporting only native amphibians to 50%; 2) to increase the number of OSMP ponds where northern leopard frogs are present but non-native, invasive American bullfrogs (Lithobates catesbeianus) are absent, and 3) to minimize undesignated trail density in northern leopard frog habitat blocks.</SPAN></P></DIV></DIV></DIV> |
