What is it about?

I use GIS and a series of historical aerial photographs to understand how the foredune habitat necessary for Western Snowy Plovers changed over time at Coal Oil Point Reserve near Santa Barbara, CA. It shows how critical the meandering slough mouth is in maintaining this habitat.

Why is it important?

The methods described here are a simple, yet effective way to understand how a foredune or sandy beach habitat is changing spatially. Many beaches are undergoing erosion due to a number of factors (dams limiting sand supply, channelization of rivers, sand retention structures like jetties, etc.). This method provides a way to determine the extent and rates of change.


This method could be implemented with existing photos & updated as new imagery becomes available.
