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 Tamboon 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

Description

The delineation of the seagrass meadows was conducted through Aerial Photograph Interpretation. The linework was digitized from stable base overlays plotted on 1:10,000 colour photo prints. Polygons were attributed with species and density from data collected at sample sites in the field. 

Statement

Dataset Source: 1:20,000 Colour Aerial Photography enlarged to a scale of 1:10,000 Photography flown on the 26th of April, 1999. Dataset Originality: Primary
