Comments: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>These data show the data from 2018 for Stream Condition Index (SCI) for Florida.</SPAN></SPAN></P><P><SPAN>River/Stream SCI is an ecological indicator for the Landscape Conservation Project for Florida. The project entails a large-scale assessment of and planning for the health of important natural resources, known as Conservation Assets (CAs), in Florida. Conservation planning at the landscape scale provides a framework for safeguarding functional ecosystems, and their interconnected processes necessary to achieve true preservation of healthy resources. Spatially explicit data from the project informs coordination and prioritization for making conservation decisions. And suite of ecological indicators was carefully selected for each CA to represent important characteristics of each Asset and offers metrics that serve to evaluate current status, monitor trends over time, and guide conservation activities with clear measures of effectiveness of the outcomes. Results are shared routinely on the Florida Conservation Planning Atlas website (</SPAN><A href="http://www.floridacpa.com"><SPAN><SPAN>www.floridacpa.com</SPAN></SPAN></A><SPAN>) and periodically in a summary report card that will be available for managers and the wider public.</SPAN></P><P><SPAN>Overall water quality is highly correlated to human disturbance (negative relationship) and to macroinvertebrate communities (positive). Because of these well-established relationships, macroinvertebrates can provide important information on impacts of human disturbance. The SCI is an index based on macroinvertebrate communities that FDEP developed to provide a robust but fairly simple measure to assess water quality throughout Florida. FDEP developed biologically-based criteria for SCI through a process of sampling in extreme conditions (relatively undisturbed vs. highly disturbed), and along a gradient of human disturbance between these two reference conditions. Results of macroinvertebrate sampling were calibrated to impacts using the Human Disturbance Gradient Index. This index is related to development intensity, habitat scores for sample sites, degree of hydrological modification, and ammonia concentrations. FDEP tested a wide variety of macroinvertebrate metrics and then chose only those metrics that were consistent and statistically-robus at discriminating 3-5 categories of flowing water quality. For additional information on SCI, see the FDEP website: https://floridadep.gov/dear/bioassessment/content/bioassessment-methods#Streams.</SPAN></P><P><SPAN /></P><P><SPAN /></P><P><SPAN /></P><P><SPAN /></P><P><SPAN /></P><P><SPAN /></P></DIV></DIV></DIV>
