The Natural History of the Cornelia Warren Estate: Camp Cedar Hill, Girl Scouts of Eastern Massachusetts by Lesley Sneddon Now Available! Camp Cedar Hill is a portion of the former estate of Cornelia Warren . In keeping with her desire to maintain the land for public benefit, Ms. Warren wished to carry this tradition beyond her life by stating so in her will.  After her death, the Trustees of Cedar Hill deeded five parcels of the estate among several beneficiaries, including the Massachusetts Girl Scouts (now the Girl Scouts of Eastern Massachusetts). To this day, Cornelia Warren’s legacy of philanthropy and social welfare continue to benefit the residents of Waltham and beyond.

BY CYD ABNET ● ENVIRONMENT ● JULY 19, 2026 The drought has significantly affected Waltham’s local flora and fauna. According to Waltham Land Trust Executive Director Sonja Wadman, the effects are cascading. “Water sources like the Charles River, Hardy Pond and our brooks shrink, resulting in concentrated amounts of pollutants and exposing critical habitat for fish, migrating birds and amphibians found along the edges of waterways and in wetlands,” she explained. Wadman also noted that trees and plants are affected by the lack of water and often die as a result. “Our volunteer trail and land restoration stewards are very busy trying their best to keep our recently planted and even more established vegetation moist,” she said.
