Leschenault Estuary (WA) Seagrass Cover 2009-2020
Aquatic flora surveys were conducted in the Leschenault Estuary between 2009 and 2020. Surveys were initially conducted in 2009 by the WA Government Department of Water (described by 2013 "Synthesis of seagrass mapping studies"), and again annually in 2015-2020 by the Department of Water and Environmental Regulation "Leschenault Estuary Seagrass Survey - Cover (DWER-105)".
Data access is provided to the initial WA DoW surveys. See associated DWER record in Data WA catalogue for access to newer surveys.

- Statement
- Surveys were conducted in April 2009, February 2015, February and March 2016, February 2017, February and March 2018, February 2019, February and March 2020. Seagrass species distribution and cover (as percentage cover in categories: 0, 1-10%, 10-25%, 25-50%, 50-75%, 75-90%, 90-100%), epiphytic cover from 2020 (as none, low, medium or high) and macroalgae cover (as percentage cover in categories: 0, 1-10%, 10-25%, 25-50%, 50-75%, 75-90%, 90-100%) were recorded at each site, using underwater video (drop camera and video tows). At approximately a third of the sites, physical water profiles, secchi depth and euphotic depth were conducted from 2018 onwards.
