I want to measure the relative usage of riparian corridors and measure how pressures, like vineyards and vineyard fence types, outside the corridor affect the diversity and density of the wildlife species using the corridors. 

The types of vineyard fencing being: high exclusion, no fencing, and whether we can determine how trellises affect diversity, density, and use.

My advisor wants to know how I'd tell who is migrant and who is a resident.

Other than visually, using genetic testing, or tagging, I'm not sure how I'd be able to determine who was a migrant using the corridor and who found it to be a suitable habitat (enough to reside there permanently). A friend of mine said mentioned a statistical analysis one can do that basically assumes who falls into what category, but I can't find an example of the analysis.

Anyone have some ideas? It would be greatly appreciated.
