Data

    This project examines seventeen Valley Oak saplings that were recruited between 1994 and 2001 (dates were determined by the authors in a previous study).  The specimens’ locations were determined in 2009 by Professor James Hayes of the CSUN Geography Department using a GPS device in the field.

    The aerial photograph of the site was obtained through the Bing Maps Aerial server.  Both the road layer and the streams layers were digitized. 

    A DEM of the Santa Monica Mountains was obtained from the USGS seamless server.  A slope layer was then created using this DEM which depicts slope in degrees.
