Title

Phytophthora cinnamomi - Likely Loss from Infection 

Alternate title

PC_RISK_0610 

Resource Type

Dataset  

Purpose

This dataset is a whole of landscape surface which shows the risk of vegetation loss from infection of Phytophthora cinnamomi. This dataset is not designed for use at a site or property scale. The three classes of loss are for display purposes at broader landscape scales, and may not reflect the risk of vegetation loss due to infection at any particular site. The datasets accuracy is dependent on modelled data. As more data is acquired to improve the model, this dataset will be reviewed. The model should not be relied upon as a sole source of risk to an area i.e. other areas may be at risk that are not shown. Furthermore, the map does not show the extent of any infection. Local advice about the potential and known impact of Phythophthora cinnamomi should be sought before undertaking high risk activities.

Refer to the metadata for the Vegetation Loss of Understorey Cover from Phytophthora cinnamomi to see how losses due to infection were modelled

Statement

Dataset Source: The Pc Risk dataset was a derived using the following process: 1. Using Species Distribution Modelling approach, create habitat model of Phytophthora cinnamomi where habitat is defined as a probability > 0.384 (95% of records fall within this threshold). 2. Create Vegetation Loss of Understorey Cover from Phytophthora cinnamomi model. 3. Clip Pc habitat model to Pc veg loss model to create Pc Risk model. 4. Pc Risk was originally classed into Low, Medium and High through standard deviations from the mean loss. 5. The ranges for Medium and High were adjusted through expert consultation to produce the following classes: 1- 23: Low >23 - 41: Medium >41: High Dataset Originality: Primary & Derived
