   Source_Contribution:

   The locations of non-native grassland on the valley floor of the San Joaquin Valley.

2. What changes have been made?

   Date: 1996 (change 1 of 1)

   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.

1. How well have the observations been checked?

   The attributes assigned to the polygon areas are from Table 11 of the SJV Recovery Plan and should be as accurate.

2. How accurate are the geographic locations?

   This coverage is extremely generalized to show general geographic areas and not actual parcel locations on the ground.

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   The coverage does not show actual locations for potential linkages, but general geographic areas within which connectivity and linkages should be promoted.

5. How consistent are the relationships among the observations, including topology?

   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.

Are there legal restrictions on access or use of the data?

Access_Constraints: none

Use_Constraints:

None. Acknowledgement of the Endangered Species Recovery Program would be appreciated in products derived from this data.
