NSW Forest Monitoring and Improvement Program Biodiversity Model Outputs: SOMs, Maxent & NARCliM (climate) Projections
This dataset contains a series of spatial outputs describing probabilistic species predictive occupancy (Species Occupancy Models, or SOM) & habitat suitability (Maximum Entropy, or Maxent) surfaces, the underlying data used to calculate these models & model projections predicting the impact of climate change on flora Maxent surfaces.
<br>
Model outputs are combination outputs dependent on known species occurrence in the landscape, the species relationship with environmental variables (covariates) such as temperature, rainfall and topography; and its predicted occurrence based on covariate analysis. Maxent models do not predict actual occupancy, but rather habitat suitability, while SOMs predict actual occupancy. confounding factors such as inter-species competition, geographical barriers and disturbance events play a significant role in species occurrence, and are not considered in Maxent or SOM.
Flora Maxent climate change projections used NSW and Australian Regional Climate Modelling (NARCliM) variables to predict habitat suitability for a baseline year 2000 and projections for 2030 and 2070.
<br>
Covariates, Fauna & Flora survey records used to create the models are included.
<br>
More detailed information regarding each model, its processes and outputs are included in the dataset.

- Data has been subject to a data assurance process. There are no known gaps in the data or if there are gaps or, if there are gaps they have been identified in caveats attached to the dataset. No changes have been made or other factors identified (for example: weighting, rounding, de-identification of data, changes or flaws in data collection or verification methods) that could affect the validity of the data; or any changes/factors have been identified in caveats attached to the asset. The data correctly represents what it was designed to measure, monitor or report.

- Statement
- <b>SOM:</b> Species occurrence data was sourced from NPWS (1994) Fauna of north-east NSW forests (NSW National Parks and Wildlife Service), as well as unpublished data held by the NSW DPI Forest Science unit. Covariate data was sourced in the main from the State Vegetation Type Map (SVTM) Modelling Grid Collection (https://datasets.seed.nsw.gov.au/dataset/svtm-modelling-grid-collection) with additional data as described in ‘NSW Forest Monitoring and Improvement Program: Final Report. Project 2: Baselines, drivers and trends for species occupancy and distribution.’ Model outputs (statistical analyses and predictive surfaces) were generated using the RPresence kernel from the R Project https://cran.r-project.org/ <p> <b>Maxent: </b>Species occurrence data from systematic fauna surveys conducted between 1991 and 1998 was sourced from NSW DPIE (e.g. NPWS 1994 Fauna of north-east NSW forests, NSW National Parks and Wildlife Service), as well as unpublished data held by the NSW DPI Forest Science unit. Additional occurrence data over the same period and spatial extent was extracted from the Atlas of Living Australia. Covariate data was sourced in the main from the State Vegetation Type Map (SVTM) Modelling Grid Collection (https://datasets.seed.nsw.gov.au/dataset/svtm-modelling-grid-collection) with additional data as described in ‘NSW Forest Monitoring and Improvement Program: Final Report. Project 2: Baselines, drivers and trends for species occupancy and distribution.’ Model outputs (statistical analyses and predictive surfaces) were generated using the Maxent kernel from the R Project https://cran.r-project.org/ <p> <b>NARCliM Projections:</b> Species occurrence data was sourced from Bionet, based on systematic NPWS surveys conducted ~1989-2000 [cf. NPWS (1994). Fauna of north-east NSW forests. (NSW National Parks and Wildlife Service)]. Additional occurrence data from 1991-1998 and equivalent spatial extent was extracted from the Atlas of Living Australia. NARCliM variables (GCM MIROC3.1; RCM R1 provided by the Science, Economics and Insights Division of DPIE NSW) along with relevant topographic layers from the State Vegetation Type Map (SVTM) Modelling Grid Collection (https://datasets.seed.nsw.gov.au/dataset/svtm-modelling-grid-collection) as described in the NRC publication ‘NSW Forest Monitoring and Improvement Program: Final Report.
