Title

Native Vegetation Time Stamping Dataset - Melbourne Growth Areas (VC68) 

Alternate title

NV2011_TS_GA 

Purpose

The Time Stamping Project has captured and "time stamped" native vegetation information within the area of the Melbourne growth corridors covered by the Biodiversity Conservation Strategy. This has established a definitive native vegetation dataset which has been used to determine habitat compensation obligations for future development proposals within these areas. The Time Stamping Project is a commitment under the Melbourne Strategic Assessment.

Statement

Dataset Source: 1. Modelled NV 2005 EVCs and QUALITY data (Source: DSE estimated data) Vegetation Type (EVC) modelling was developed at scales between 1:100,000 and 1:25,000 as a result of a number mapping projects during the 1990s and 2000s. This data is extracted from the dataset NV2005_EVCBCS. Native Vegetation Quality data produced largely from image analysis of LANDSAT imagery and thousands of site-based surveys covering Victoria. This data is extracted from NV2005_QUAL. 2. Rapid vegetation assessments ie. Better than the modelled NV2005 data but not the full on-site vegetation survey (Source: DSE estimated data) Rapid Assessments of vegetation type and quality have been carried out by experts using a combination of Air Photo Interpretation, over the fence surveillance and general expertise. Only summary attributes from the survey data have been included (see attributes) 3. Full Vegetation Quality Assessments. (Source: Site Survey Data) All Site Survey Data was captured according to the Vegetation Quality Assessment Manual (2004) between 2008 and 2011and has undergone rigorous Quality Assurance procedures. These include DSE trained and registered Vegetation Quality Assessors. Random Audits of assessors work. Thorough checking of submitted data. 4. Road extents and Man Made Features (Source: DSE estimated data) Road Extents: Using Vic Map data, roads were buffered by a minimum estimated width to exclude any DSE estimated native vegetation data, as follows: Local and collector roads were buffered by 5m either side of the centre line, freeways, sub-arterial, arterial and highways were buffered by 10m either side of the centre line. Other man-made features include buildings, water-bodies and driveways. These were captured using Aerial Photo Interpretation. Man Made Features and Road extents are identified as Non native vegetation. 5.
