PEC is a proud recipient of software grants through the Earth Science Research Institute’s (ESRI) Conservation GIS Program.

PEC uses ESRI’s ArcGIS software to produce high-quality maps and to analyze potential project impacts. This helps us convey important information to the public, partner groups and decision-makers about land use proposals, active campaigns, as well as land conservation successes and opportunities.

This grant provides PEC with up-to-date mapping software and skills training, allowing us to continue to innovate.

A big thank you to ESRI’s Conservation Program for their continued support of non-profit work in the conservation field!
