Wallkill River National Wildlife Refuge in New Jersey

These selected areas were outlined in the 1995 Environmental Assessment entitled, "Proposal to Establish the Rappahannock River Valley National Wildlife Refuge". The purpose of this data is to serve as a spatial reference of refuge boundaries for other data layers in GIS and mapping applications. It is specifically not intended to be used as a land survey or representation of land for conveyance or tax purposes.

Survey file was imported to ArcInfo, boundaries were digitized and labeled. Updates to the file have included a tract by tract update in 2000 using survey files and the survey scale factor that needed to be applied to rectify past position problems. Digital file was subsequently updated using survey and collateral data for newly acquired tracts, then stepped through 3 levels of quality-control review for spatial and thematic accuracy.

Refuge boundaries define areas that are approved by U.S. Congress for acquisition into the National Wildlife Refuge System, or are currently owned by USFWS. Arcs are coded with an item "boundary" with the type of boundary line; polygons are coded with an item "status" that describes their ownership status.
