I am displaying three different layers on a map, essentially three separate habitat types. Each have their own colour. In cases, 2 or 3 of the layers overlap in part (essentially showing where habitat types overlap). How can I display this overlap in the legend?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
If you have more time to play with data, you can intersect only two layers a time just to identify and symbolise intersections of each shapefile (1 and 2, 1 and 3, 2 and 3)
