Alternative title(s)

fe_coast_1750_VISmap_3786

Abstract

This is the original extant Forest Ecosystem map for the South Coast sub-region, comprising a number of different models and API data. Expert botanists developed the map within extant vegetation, by assigning API polygons to vegetation groups, determined by an ecological classification process using PATN software. The processes used were approved and signed off by a review team of expert botanists including two independents, one NPWS representative and one SFNSW representative. On cleared land, a combination of soils, GAMs modelling, and classified site data was used to assign vegetation groups to distinct topographic and soil patterns. The extant map was derived from masking the pre-1750 map to the extant vegetation. 101 distinct ecosystems have been mapped in the extant map for this sub-region.; ; VIS_ID 3786; ; ANZLIC: ANZNS0208000141

Note that this map was superseded by VIS_IDs 3858 & 3859

Lineage

Extant vegetation was mapped for the South Coast sub-region of the Southern CRA area, using a multi-stepped approach. The pre-1750 vegetation map was compiled using the procedure described below, and then cut with a mask of extant vegetation derived from the Aerial Photograph Interpretation layer (see CRAFTI API project report, DUAP in prep) and the Eastern Bushland Database for two small sections not covered by API mapping. The coverage of existing vegetation was derived by gridding all API codes other than plantations (P and PP), excluded areas (EX), bare ground (A) and exotic forest (CV).Firstly 3740 full floristic vegetation survey sites were classified into vegetation communities using PATN software. Then Aerial Photograph Interpretation polygons were assigned to the PATN classes (note: air photos were flown between 1990 and 1997). Modelling of pre-1750 vegetation on cleared land used the following approach. Twenty Generalised Additive Models (GAMs) identified the environmental envelopes, and mapped areas with high probabilities of occurrence, for all ecosystems with ten sites or more. The soil landscape data layer (Lithology and Soils Project report, DLWC 1999) was used to identify likely pre-1750 vegetation. Expert models were used in a few instances where botanical experts were able to identify the suite of conditions associated with a particular ecosystem, but GAMs were not possible. Order of precedence for the 33 layers incorporated in the map, was based on the opinion of expert botanists and confidence in each model (those with lowest confidence were placed under those of higher confidence).

Explanation

Conceptual Consistency

Explanation

Logical consistency tests were performed on all layers used in the modelling process. These included checking for consistency in origin and geo-referencing between layers. A small number of forest ecosystems were not mapped due either to a lack of data, or the scale of the regional map. These were FES's 26, 30, 31, 33,105,125142, and143.

Topological Consistency

Explanation

Checked for missing attributes All attributes were checked

Absolute External Positional Accuracy

Explanation

The derived forest ecosystem type layer is georeferenced. Precision with respect to linear features: 10m to 50m. Positional accuracy estimate determined from comparisons with Landsat imagery, geo-referenced to level 10.

Non Quantitative Attribute Accuracy

Explanation

The attribute of this dataset is the forest ecosystem type which is defined as any group of tree-dominated stands which possess a general similarity in composition and character. There are approx. 200 forest ecosystem types identified and described across the whole of the CRA Region. A subset of these vegetation types were found in the South Coast sub-region. Spatial units were attributed as described in the Lineage section of this metadata statement. While the experts and field assessors undertook a limited accuracy assessment, it is not possible to give a percentage value of how well the attributes conform to the classification method. A more detailed assessment will be provided in the final project report. Modelled forest ecosystem types were given a reliability code, rated from 1 (high) to 5 (low).
