noted earlier in this document, aquatic vegetation, invertebrate and water quality monitoring <br />(e.g., dissolved oxygen, clarity, salinity) will be conducted by Refuge staffand volunteers. <br />Monitoring not only providescritical information regarding the health of Round Lake, it <br />providesinformation regardingthe condition and abundance of waterfowl foods. Information <br />obtained by sampling aquatic vegetation and invertebrateswill be used to track the results of <br />water level management activities. We expect to conduct vegetation surveys at intervals ranging <br />from 1 –5 years, depending on water level management activitiesor natural climatic events, <br />such as droughts.Regular monitoring and sampling of aquatic invertebrates, including those <br />residing in the substrate, also isnecessary becausethey provide an additional source of <br />waterfowl foods. Habitat monitoring in the uplands alsoisimportant. The ability of a habitat to <br />support wildlife is dependent on the species composition and structure of the habitat. Surveys to <br />identify thesecomponents, aswell asthe presence of invasive species,will be performed. The <br />monitoring results will enable refuge staff to identify what management actions are necessary <br />and appropriate. <br />Wildlife monitoring will include surveys relating to eagle nest success, bird migration, invasive <br />species, amphibians,and reptiles. Surveys specifically targeted for listed state or federal species, <br />such as Blanding’sturtles, as well as general wildlife use will be conducted as needed.As with <br />other Refuge waterbodies, fish surveys will be conducted on a 3 –5 year cycle. Fish surveys <br />provide information regarding habitat management and also support the Refuge fishing program, <br />and potentially,the MNDNR FIN program. <br />Following the remediation of TCAAP-sourcecontamination in Round Lake, we expect that there <br />will be additional monitoring of natural resources in the larger environment within which the <br />Round Lake Unit is located.While we do not anticipate being the lead agency for such <br />landscape level natural resource monitoring, we will be actively involved as a natural resource <br />partner in that monitoring as well. <br />Epilogue <br />The future value of the Round Lake Unit of the Minnesota Valley National Wildlife Refuge for <br />wildlife conservation and its use by othersfor wildlife-dependent recreation depends upon the <br />level of clean-up attained via the Superfund remediation project. The Service presumes that the <br />current ecological risk posed to the Round Lake ecosystem will be mitigated via the actions of <br />the Superfund remediation project in such a manner that enable this vision to be fulfilled. <br />8/6/2013 18 USFWS RLMP <br />
