- Summary
- The project quantified seagrass occurrence and density using in situ observations based on a random design that locates sampling points throughout the Loxahatchee River estuary. At each sampling point, a 9m2 collapsible quadrat was used to collect seagrass presence/absence within each 1m2 square of the 9m2 grid. Results from this project provide landscape-scale, species specific assessment of seagrasses in the estuary.
- Parameters
- seagrass presence, 2010 data includes Water depth (cm), predominant substrate type (much, sand, rock/shell, detritus), muck depth if present, Density (m2), acreage.
- Notes
- Data after 10/21/2007 is excluded from SEACAR because Program 3017 has quadrat level detailed data for Loxahatchee seagrass starting after this date.

- Method
- Landscape-scale Mapping Methods: performed while snorkeling. Quantifed seagrass presence or absence by deploying a 9m2 quadrat at each sample point. 2010 data includes water depth and seagrass density: visually estimated in cells where seagrass was present, using the following categories: (1) low density (< 5% coverage); (2) moderate density (> 5% but < 90% coverage); and (3) high density (= 90% coverage)
