Brief description

Aquatic flora surveys of the Hardy Inlet were conducted from the top of Molloy Island and the Scott River Basin to the mouth of the Inlet. Surveys were initially conducted in 2008 by the WA Government Department of Water (described by 2013 "Synthesis of seagrass mapping studies"), and again in 2008 & 2020 by the Department of Water and Environmental Regulation "Hardy Inlet Seagrass Survey - Cover (DWER-112)". Data access is provided to the initial WA DoW surveys. See associated DWER record in Data WA catalogue for access to newer surveys.
