The American Society for the Protection of Nature in Israel (ASPNI) was founded in 1953 to protect pristine and unique natural areas from heedless development. The system of National Parks and Preserves of Israel were designated, and today SPNI operates a system of field schools throughout the land to provide Israelis with direct contact and appreciation of nature, and thus provide a supportive base for SPNI's environmental initiatives and campaigns, such as: preservation of open space, mass transit, protection of coast lines, clean water and air, protection of endangered species and habitat.

The Walden Woods Project was founded in 1990 to protect land of ecological and historic significance surrounding Walden Pond. At that time nearly half of the Walden Woods' 2,680 acres remained unprotected from development. Two large tracts of land (a total of 43 acres) were under immediate threat as developers sought to construct an office park and a large condominium complex in close proximity to Walden Pond. In January 1991, the Walden Woods Project raised enough money to buy the 25-acre Bear Garden Hill site. A few years later, the Project acquired a second parcel, known as Brister?s Hill. In 1998, the Walden Woods Project opened The Thoreau Institute at Walden Woods containing over 8,000 volumes and 60,000 items of Thoreau-related materials and launched its two trademark teacher education programs, Approaching Walden and Finding Walden.
