The Land Alliance owns and/or manages eight nature preserves, totaling 166 acres.  The majority of these preserves were gifts from The Nature Conservancy and ExxonMobil Corporation, though the Land Alliance has also worked with private parties and municipalities to acquire preserves, such as the Wawapek Preserve in Cold Spring Harbor.  In addition, the Land Alliance holds conservation easements on 195 acres of privately held land.

Land protection is the first important step, but without ongoing stewardship, land is vulnerable to impact from invasive plants and animals that can render it unhealthy.  Key facets of stewardship include:

  • Trail maintenance
  • Managing invasive species
  • Monitoring flora and fauna
  • Periodic boundary checks
  • Occasional plantings
  • Public programming

With a small stewardship staff, the Land Alliance relies heavily on volunteers and organizational partners to carry out these activities. We are most grateful to our volunteers, businesses and other partners who mow fields, remove unhealthy trees and keep meadows open, often donating their time and expertise to maintain these special places in our community.

Our 195 acres in conservation easements require an annual monitoring visit to ensure that activities on the conserved properties are in compliance with the terms of the easement.  When an easement is established a baseline inventory is generated to provide a record of the condition of the property at the time the easement goes into effect. Land Alliance staff work with property owners to best preserve the conservation value of their land.
