Question 3 gets to the heart of the analysis: What is the connection between warbler territory locations and vegetation?
Now that the pattern of warbler abundances has been elucidated, we can determine whether warblers and vegetation are associated. Within BoundarySeer, this can be accomplished using boundary overlap statistics (Jacquez 1995). Overlap looks at the spatial association between two sets of boundaries (or a set of boundaries and a set of other spatial features).
