Brief description

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.
