These data show the results from the Lake Vegetation Index (LVI) for Lakes and Ponds of Florida for 2018. The LVI is one of the procedures that FDEP uses in its Bioassessment and Restoration programs to determine the health of vegetation of lakes and ponds. LVI has been adopted as one of the ecological indicators of the health of lakes and ponds. LVI is an ongoing program with continued data collection in sample sites that may vary over time but are regularly collected in widespread sample sites throughout the state of Florida. <\/SPAN><\/SPAN><\/P>

LVI is an ecological indicator for the Lakes and Ponds Conservation Asset of the Florida Landscape Conservation Project (LCP). The LCP 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 required for maintaining healthy resources. Spatially explicit data from the project informs coordination and prioritization for making conservation decisions. Additionally, a 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 management effectiveness. Results are shared routinely on the Florida Conservation Planning Atlas website (<\/SPAN><\/SPAN>www.floridacpa.com<\/SPAN><\/SPAN><\/A>) and periodically in a summary report card that will be available for managers and the wider public.<\/SPAN><\/SPAN><\/P>

The Lake Vegetation Index is a bioassessment procedure that measures the degree to which a freshwater lake supports a healthy, well-balanced plant community. The LVI is a multi-metric index that evaluates how closely a lake plant community resembles one which would be expected in a condition of minimal human disturbance. It is based on a rapid field assessment of aquatic and wetland plants as integrators of various effects of human disturbance over time. Plants respond to physical disturbances such as the introduction of exotic species or lakeshore alterations, and chemical disturbances such as the introduction of excess nutrients, particulates, or herbicides from surrounding land uses.<\/SPAN><\/SPAN><\/P>

Four metrics comprise the index: % native taxa, % FLEPPC Category 1 invasive exotic taxa (determined by the Florida Exotic Pest Plant Council [FLEPPC]), coefficient of conservatism (C of C) of the dominant taxon or co-dominant taxa, and % sensitive taxa (C of C ≥ 7). The coefficient of conservatism is a number from 0 to 10 that indicates how broad or narrow a taxon\u2019s ecological niche is, as determined by expert botanists. Exotic and ubiquitous weedy native taxa have low C of C scores, and taxa that display fidelity to a particular community and are sensitive to disturbance have high C of C scores.<\/SPAN><\/SPAN><\/P>

The LVI was developed in 2005 by relating plant metrics with indicators of human disturbance, so that the index responds to the effects of human disturbance rather than natural variability among lake plant communities.
