Joselin Matkins, executive director of Teton Regional Land Trust and a highly involved and beloved Teton Valley community member, died Friday.

The Teton County, Idaho, coroner’s office ruled her death a suicide.

Matkins, 42, was an East Idaho native who left a lasting impact on conservation in the region, first leading the Sagebrush Steppe Land Trust in Pocatello, then moving to Teton Valley in 2013 to work for and then direct the Teton Regional Land Trust.

She served on several nonprofit boards, including Teton County Idaho Search and Rescue, for which she also volunteered. In 2020, she received the Dawn Banks Nonprofit Leadership Award for her collaboration with other organizations on conservation projects.

When she wasn’t watching sandhill cranes or inventorying land for conservation easements, she enjoyed mountain biking, boating and skiing.

Matkins departed her Tetonia home for a bike ride Friday morning, the Teton County Sheriff’s Office reported. Her partner became concerned for her welfare and called the sheriff’s office about an hour and a half later.

Teton County Idaho Search and Rescue mobilized and began sending small teams to comb neighborhoods of north Alta and east Tetonia as well as the nearby public land access points.

An hours-long search of the northern corner of the valley, which involved most of SAR’s manpower as well as Air Idaho Rescue, found Matkins at 6:55 p.m. on private property in the North Leigh area.

“We are very appreciative of SAR and their efforts,” TCSO public information officer Mitch Golden said.
