Habitat Analysis
Tutorial data
About this folder
The data in this folder forms the tutorial data for the book
Using ArcGIS Geoprocessing Tools. In the tutorial you'll locate areas with the best
potential for supporting the Californian gnatcatcher, a non-migratory songbird
that lives in south-western California and north-western Baja. Like so many
species today, the gnatcatcher population has been in decline due to urban
areas encroaching on its habitat. In exercise 1 you'll find patches of coastal sage scrub near proposed roads.
In exercise 2 you'll join fields to the vegetation data.
In exercise 3 you'll add a script to a toolbox to clip multiple datasets. In
exercise 4 you'll create a new model to find potential high quality habitat patches.
In exercise 5 you'll create a new model, add the model created in exercise
4, and find areas of high quality habitat that might be impacted by the proposed roads.
The impacted high quality habitat patches should be identified to see if there are indeed gnatcatchers present, and the roads
impacting habitat patches should be assessed to see if there alternative routes that can be taken.
Below are brief descriptions of the data sources used in the tutorial.
Climate
- Shapefile representing general climate zones.
Elevlt250
- Shapefile representing areas where the
elevation is less than 250m.

study area.
Slopelt40
- Shapefile representing areas where the slope of the
land is less than 40%.
Veg_table
- DBF file containing information to be
joined to vegtype.
Vegtype
