Sydenham Inlet Seagrass 1999 

Alternate title

SEAGRASS_SYDENHAM_INLET_1999 

Purpose

This layer is the result of a baseline survey of seagrass within Victoria. Ecological research into the health of seagrass meadows requires the type of detailed information collected in this baseline survey. 

Supplemental Information

Current Design Issues: This information represents a "snap-shot" in time of the spatial extent of seagrass meadows in Sydenham inlet. The area of coverage and density of the various species of seagrass changes with time, both seasonally and yearly. Future Design Issues: Future design considerations may include the adding extra species and recording the condition of the seagrass in relation to epiphyte coverage. Related Documents: None
