New England Protected Open Space

The New England Protected Open Space dataset maintained by Harvard Forest is a compilation of existing open space datasets in the New England region including The Nature Conservancy's Secured Areas, National Conservation Easement Database, Protected Areas Database of the U.S., and data provided by states and land trusts.

Two formats of the data are available here: a file geodatabase feature class (POS.gdb.zip) and a shapefile (POS_shp.zip).

It is recommended to use the geodatabase feature class if you have access to Esri products, as the POS field names are all longer than 10 characters and are truncated in the shapefile version.

Version 1.1 is a partial update, rather than an exhaustive update using all data sources - please read the metadata for more details!
