Proposed areas where connectiviy and linkages between isolated habitat on the San Joaquin Valley floor and natural lands in the surrounding foothills should be promoted.
To illustate Valley Floor Linage areas listed in Table 11. of the Recovery Plan for Upland Species of the San Joaquin Valley.

The attributes assigned to the polygon areas are from Table 11 of the SJV Recovery Plan and should be as accurate.
Arcs connect to each other at nodes. Arcs have direction and left and right sides. Arcs that connect to surround an area define a polygon.
The coverage does not show actual locations for potential linkages, but general geographic areas within which connectivity and linkages should be promoted.
This coverage is extremely generalized to show general geographic areas and not actual parcel locations on the ground.

The locations of non-native grassland on the valley floor of the San Joaquin Valley.
Dan Williams and Patrick Kelly of ESRP used the locations of existing non-native grassland and scrub communities on the valley floor as well as physical features such as the Chowchilla Canal to determine the locations for areas where connectivity and linkages should be promoted. The selected areas were created as polygon coverages in ARC/INFO by Nancy Norvell of ESRP. Subsequent edits to the polygon locations were done in ARC/INFO by Scott Phillips of ESRP.
