Phase I: Using GIS to Identify Target Areas with Maximum Environmental Impact


With the support of a 2016 Janice Hollmann Grant from the Maryland Environmental Trust (MET), a statewide land trust and independent unit of the Maryland Department of Natural Resources, UER developed a series of GIS maps and strategic search capabilities to identify optimal locations for Eco-Functioning Spaces in Montgomery and Prince George's Counties.  UER was assisted in the creation of three specific maps by Salisbury University's Eastern Shore Regional GIS Cooperative.

As part of the grant-funded work, UER identified areas of both counties that, if restored with Eco-Functioning Spaces (EFS), will materially strengthen the natural environment in some of the most degraded areas of Montgomery County and Prince George’s County. Part of this strategy will be to identify and target privately-owned land parcels that are:

  • Adjacent to protected natural areas,
  • Adjacent to other lands that have already received public investments in green infrastructure, or
  • Unprotected natural areas that significantly affect environmental quality.

EFS in these private lands will enable UER to magnify the collective environmental impact of large public investments in ecosystem restoration.

The funds for this work were provided by the Maryland State Highway Administration (SHA).  We thank MET and SHA for their support and partnership.
