Flying Fox habitat spatial data (Edition 1, last revised 08 April 2011): https://datasets.seed.nsw.gov.au/dataset/grey-headed-flying-fox-foraging-habitat2f40a
The above data was processed and visualized using a combination of ArcGIS (fire severity and NVIS was analyzed in version 2.6, all other data was analyzed in version 2.5) and R version 3.7. All required input data are provided in the data folder. R code to process spatial products and analyze data are in the following scripts:
- ghff_2012_2013_fire_response.R: mixed effect models to evaluate factors affecting grey-headed flying fox (GHFF) response to fires
- burned_habitat_comparisons.R: GAMs (generalised additive models) to explain variation in burned foraging habitat between previous focal and anomalous fire seasons
- fire_and_forest_vizualizations.R: plots vizualizing main text figures
