• Location: Nationwide (national parks, forests, wildlife refuges across the U.S.)
• Benefits: Hands-on conservation fieldwork; residential team experience; leadership and outdoor skills; pathway to advanced SCA roles

SCA Residential Internships place you directly in the field, working on conservation projects at national parks, forests, and wildlife refuges. As part of a National Conservation Crew, you live on-site with a small team of other high school students and spend your days doing physical, hands-on environmental work.

Your work may include trail building and maintenance, habitat restoration, invasive species removal, and ecosystem protection projects. You’ll live in tents or basic housing, cook meals with your crew, and work under experienced adult field leaders who teach you outdoor safety, teamwork, and leadership. The experience is demanding, but it builds resilience, collaboration, and confidence in a way few programs do.

National Conservation Crews are typically open to high school students ages 15–19. Most crews run 2–5 weeks during the summer and prioritize students who are comfortable working outdoors and motivated by service and conservation.

7. Conservation Corps North Carolina – Youth Conservation Crews

You can choose from several crew types—trail work in Raleigh or Davidson, habitat restoration in Durham, or Forest Service projects in Pisgah National Forest. If you want a deeper outdoor experience, the Youth Camping Crew spends the entire session living and working in the forest. Day crews return home each evening.

Your work may involve trail building, invasive species removal, habitat restoration, forestry projects, sign installation, and land stewardship tasks.

To join, you must be a North Carolina resident, age 15–18, and available for the full program dates. Prior experience isn’t required. Applications open in early March, with interest forms available year-round.
