Description

Seagrass percent cover data from long-term monitoring of 20 selected sites sampled through the Texas Seagrass Monitoring program from August 2011 to September 2018.

Methods & Sampling

Species composition and areal coverage were obtained from two replicate quadrat samples per station at two cardinal locations from the vessel boat (starboard-bow and starboard-stern). Percent cover of areal biomass was estimated by direct observation, looking down at the seagrass canopy through the water using a 0.25 m2 quadrat framer subdivided into 100 cells.

Additionally, we include percent cover data from long-term monitoring (2011-2018) of 20 selected sites sampled through the Texas Seagrass Monitoring program. Survey methods are described in Congdon et al. 2019.
