Julia Washburn is associate director of education and interpretation for the National Park Service. She says in a time of budget cuts, the agency has to find ways to still meet its goals. "We are not likely to get a lot of money in this current economy. This is about doing different work with the money that we have and redirecting resources into it. Ms. Washburn says one of the most important services that the Park Service provides every day is nature interpretation. she says, "Interpretation is a form of informal education. Essentially, it is a word that we use for the people in parks that explain the park or help orient you. So park rangers are interpreters. They orient you to the place you are in and help you make connections, emotional and intellectual connections, with the place.
