Geographical Information System (GIS) and remote sensing tools have become an essential component in wildlife research. Open source geospatial (FOSS4G) tools were shown to hold tremendous opportunity. In fact, there is a great potential for the use of free and open source geospatial tools in wildlife ecology research. Wildlife ecologists and practitioners can advocate concentrated efforts towards a common, customisable and free research platform. We introduce the concepts and terms related to the free and open source geospatial software; and then compare the open source tools with the proprietary ones. We finally train the students in applying these tools to solve wildlife and conservation problems through hands on approach.
