Evaluating Landscape Permeability in Quantum

Disclaimer

Please note that this Wiki tutorial has been produced for the GEOM4008 Advanced topic in Geographic Information Systems class at Carleton University.

Introduction

The objective of this project was to develop a method to evaluate landscape permeability for large carnivores using only free and open-source software (FOSS). This tutorial has been created to allow non-GIS individuals to successfully complete this analysis in Quantum GIS (QGIS) using the Grass Plugin. This tutorial will be carried out while analyzing the landscape permeability for grey wolf movement on Vancouver Island. The final result from this project will be a landscape permeability map and provide invaluable insight into the movement of the grey wolf. This information can be used to implement more successful conservation strategies, facilitate ecosystem-based management (EMB), and better understand the genetic flow in the island’s population.

Data

Before beginning this tutorial in QGIS a variety of data is needed. In order to evaluate landscape permeability the data must be specific to the area and animal chosen to analyse. After the animal has been chosen parameters that would inhibit movement in the study area should be studied and then data must be located. For our analysis of movement on the grey wolf on Vancouver Island we used a combination of freely available data, privately owned data, as well as data we created for the purpose of this tutorial. See Table 1 for the data used and the source of the data.
