Zack Porter, Executive Director
Zack Porter is a co-founder of Standing Trees and a passionate advocate for America's wildest places. Born and raised in New England, Zack developed a deep bond with wild nature at an early age, and he has dedicated both his personal and professional lives to the cause of its protection and restoration. Zack's career in public land management and wildlands advocacy began two decades ago with the US Forest Service in Washington's North Cascades and Idaho's Northern Rockies. A graduate of the University of Montana, Zack worked for a decade to protect wild rivers, mountains, and prairies with Montana Wilderness Association and All Against The Haul. Among Zack's proudest accomplishments are working with indigenous communities in the US and Canada to successfully block ExxonMobil from expanding Tar Sands strip mining operations in northern Alberta, and protecting western Montana's wildlife and wildlands from motorized recreation and resource extraction. Returning with his family to New England in 2018, Zack worked with Northeast Wilderness Trust and Conservation Law Foundation, meanwhile co-founding Standing Trees to fill a gap in the regional environmental nonprofit community. Today, Zack is grateful for the opportunity to take Standing Trees to the next level as its first Executive Director, and enjoys keeping one foot (or at least a few toes) west of the 100th meridian as the Land Protection Committee Chair for The Wilderness Land Trust. When not working to protect wild places, Zack can be found exploring them with his wife, daughter, and black lab.
