PORTLAND – Portland Trails announced Monday that Kara Wooldrik will be its new executive director, replacing Nan Cumming, who left the organization last month.

Wooldrik is now education director for Maine Audubon. She is expected to become Portland Trails’ full-time director in early April, the organization said in a news release.

Wooldrik has undergraduate and graduate degrees in environmental education.

She will be only the third full-time executive director of the 20-year-old Portland Trails, a nonprofit urban land trust and trail building organization.

Alix Hopkins led Portland Trails during its early years, and Cumming served for the past 12 years.

Cumming resigned in January to take a position with the Maine Crafts Association.

“We see ourselves as being more than a simply trail-building group,” said Aurelia Scott, the agency’s interim director. Scott said Portland Trails wants to make Portland a model for people-powered recreation and transportation.
