There is a very good book in spatial analysis that you could learn concepts from in case you are thinking about what analysis you will end up doing. The book is by Marie-Josée Fortin and Mark Dale called Spatial Analysis: A Guide for Ecologists.
If you want to learn how to you a GIS software, I recommend you ESRI materials, such as this file: https://www.esri.com/library/bestpractices/forestry.pdf
ESRI provides a lot of material and courses for free online.
If you want to talk about what exactly you want to do, I might be able to help you more.
