9-second gridded continental Australia change in effective area of similar ecological environments (cleared natural areas) for Amphibians 1990:1990 (GDM: AMP_r2_PTS1)


Proportional change in effective area of similar ecological environments for Amphibians as a function of land clearing within the present long term (30 year average) climate (1990 centred) based on Generalised Dissimilarity Modelling (GDM) of compositional turnover. This metric describes the effects of land clearing on the area of similar enviro... more

Proportional change in the area of similar ecological environments was calculated using the highly parallel bespoke CSIRO Muru software running on a LINUX high-performance-computing cluster, taking GDM model transformed environmental grids as inputs. Proportional change was calculated by taking the area of present ecological environments similar to each present cell as the denominator and the area of present cells with their contribution scaled by the natural areas condition index (0 degraded to 1 intact) as the numerator. More detail of the calculations and methods are given in the document “9sMethodsSummary.pdf” provided with the data download.

About this Project

1173.3 Strat: WPC Global Prot Area Ass


This project employs macroecological modelling and analysis techniques pioneered by CSIRO to assess present and future representation of terrestrial biodiversity within the world’s protected-area system. The project aims to address four main questions: 1. How adequately does the world’s protected-area system represent current patterns of compositio... more

Biodiversity Impact Analyses


This activity brings together the modelled patterns of species compositional turnover over time with the contextual land use data layers to estimate a range of metrics of projected change for biodiversity for all locations in Australia. The magnitude and character of climatic changes are described for each cell, based on the overall (whole landscap... more
