Conservation Land

Vine BrookConservation Areas

Lexington has over 1,300 acres of conservation land, including 26 conservation areas with trail access. This conservation land creates a patchwork of forests, fields, and wetlands that provides habitat for plants and wildlife and adds to the quality of life for Lexington residents.

On Lexington's conservation land, visitors find the opportunity to walk, jog, picnic, birdwatch, cross-country ski, bicycle, and garden. Over 50 miles of trails cross our conservation land, many with boardwalks over wet areas.

Volunteers of the Lexington Conservation Stewards help to care for Lexington's conservation land and keep the trails open for everyone to enjoy.

Land Management Planning

The Lexington Conservation Commission, Conservation Division staff, and volunteer Conservation Stewards are committed to managing Lexington’s conservation land for:

  • passive recreation and education programs
  • protection of habitat for plants and animals;
  • provision of ecosystem services such as flood protection, nutrient cycling, and purification of air and water;
  • open space connectivity for both wildlife and trail users; and
  • preservation of community character including scenic views and historic features.

Managing these elements responsibly over time requires careful planning, on both the town-wide and individual property scale. In 2014, the Lexington Conservation Commission worked closely with the Massachusetts Audubon Ecological Extension to develop a comprehensive conservation management guide, Principles and Policies for Management of Lexington Conservation Land. The Commission formally approved this guide in February 2015.

This guide, as well as all individual conservation property land management plans approved by the Commission, can be found HERE. Currently, the Commission has approved land management plans for Cotton Farm, the Leary Parcel, and Idylwilde Conservation Area.

Walking your Dog on Conservation Land

The Conservation Commission has passed regulations regarding the walking of dogs on conservation land. These regulations are in place to ensure that all visitors have a safe and comfortable visit to Lexington's conservation areas. For more information, read the press release>>

  • stay at the guardian’s command;
  • do not charge or chase any person, dog or wildlife, nor engage in any aggressive behavior;

  • No more than 2 dogs per person are permitted
  • Guardians must carry a waste bag for each dog in their care and pick up and properly dispose of their dogs' waste
  • Guardians must carry a leash for each dog in their care
