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. See metadata for each version for version-specific information and information about fields.

Important note about versions of NE POS: NE POS is a dataset we maintain for research purposes, and research projects can take varying lengths of time. Versions of NE POS may be uploaded to Zenodo "out of order," meaning older versions of data may be uploaded after more recent versions have been published.  Use the version number to identify the recency of the data rather than the date of upload.

Version 1.0.1 was uploaded in January 2023 but has the same spatial data as v1.0.0. Version 1.0.1 has an extra column that was used for analysis, and the upload is provided with a subset of all NE POS fields. For the same spatial data with all NE POS fields, or a geodatabase feature class, use v1.0.0.
