Razorback Musk Turtle

neers (USACE) reservoirs may impact critical habitat parameters for mud and musk turtle spe-cies. This technical note identifies mud and musk turtle species and habitats potentially impacted by USACE reservoir or other water-control projects as reported by resource managers (Table 1). Current state and/or Federal legal pro-tection status is summarized (Figure 1, Table 2), as is the distribution of USACE Districts and res-ervoir projects potentially impacted by mud and musk turtle conservation issues. Life-history summaries and habitat requirement descriptions are given for each mud and musk turtle species identified as potentially impacted at reservoir operations. This group includes 10 species with legal protection in at least one state and one Feder-ally threatened species. Three of these species are associated with environmental issues at 23 USACE projects from 1 USACE District. The collective range for these 10 environmentally sensitive species is widespread throughout the central, southeastern, and Atlantic coastal regions of the United States (Figure 2). Mud and musk turtles are found in almost any quiet water within their range to include: swamps, wetlands, sink-holes, rivers, creeks, ponds, lakes, reservoirs, etc. Mud and musk turtles are placed in a separate group because of morphological and behavioral differences as well as the diversity of aquatic systems inhabited.
