"The following internships are available at the World Wildlife Fund – United States. They are designed typically for graduate students, although some may be appropriate for advanced undergraduates. Projects can be undertaken over the summer (with extensions, as necessary, into the fall semester).
Most projects could also be extended over the course of one or two semesters as part of a student’s course work or thesis requirements; advance arrangements would be necessary with faculty advisors. Internships are typically unpaid unless otherwise noted, but facilities, library resources, and computers at WWF headquarters are available. Hours are flexible. To qualify for an unpaid internship, the student must provide documentation that they are receiving credit from their university, or that the work they will be performing is consistent with a course requirement."
