Distribution of Deer on Victorian Public Land_OLD

dataset: DEER_DISTRIBUTION_OLD
Model-based predictions of the distribution of deer on Victorian public land. Model predictions are based on camera-trap and deer sign surveys at 317 sites across Victoria conducted between 2021 and 2023. The raster data is divided into four layers/bands for the four species analysed in this study: Sambar deer (Cervus unicolor), Fallow deer (Dama dama), Red deer (Cervus elaphus) and Hog deer (Axis porcinus). Distribution estimates are presented as a categorical value of model confidence in deer occupancy per square kilometre of public land within each grid cell. The values represent (i) the Smallest estimated range (5th percentile), (ii) the Average/median estimated range (50th percentile), and (iii) the Largest estimated range (95th percentile). The technical report accompanying this data is available from the Arthur Rylah Institute (ARI) website: https://www.ari.vic.gov.au/__data/assets/pdf_file/0035/686591/ARI-Technical-Report-368-Deer-abundance-in-Victoria.pdf The raster data may be loaded into programs such as R or QGIS for analysis. When opening the data in QGIS, undertake the following steps: 1) Follow 'Layer > Add Later > Add Raster Layer' to select the tif file to be added 2) Right-click on the added layer in the 'Layers' panel and select 'Properties' 3) Visualise the distribution of one of the four species of deer by selecting 'Symbology > Band Rendering > Render Type = Paletted/Unique Values' 4) Choose the band (species) you wish to display 5) Click the 'Classify' button 6) The layer values can be renamed according to the associated XML datafile. The values are: 0 = Not present, 1 = Largest estimated range (95th percentile), 2 = the Average/median estimated range (50th percentile), and 3 = Smallest estimated range (5th percentile)
