Part 1<\/strong><\/p>\n

For this group of exercises (6, 7 and 8), species distribution modelling is demonstrated using Maxent (Philipps et al., 2006) to show how to produce the suitability maps for a species based on its occurrence and environmental layers for the area covered.<\/p>\n

Downloading Bioclim Data and processing in ArcMap<\/span><\/b><\/div>\n
    \n
      \n
    1. The Bioclim files are found at http:\/\/worldclim.org\/download<\/a><\/li>\n
    2. Click on Current conditions select the Generic grid->30 second resolution->Bioclim 1-9 & 10-18 and the available Tiles will come up<\/li>\n
    3. Click on 411 which contains New Zealand; unzip the resulting download<\/li>\n
    4. Open a new Arcmap, set the projection to WGS84 and add the New Zealand coastline shapefile (nzcoast.shp) and the unzipped Bioclim layers<\/li>\n
    5. Use ModelBuilder to define the Bioclim layer projections and clip to the NZ coastline.<\/li>\n<\/ol>\n<\/ol>\n
