990 for the year ended December 31, 2025

Program accomplishments

  • Easement Acquisition: PTLT continued to acquire new easements to protect property in Southern Maryland in perpetuity. Two new easements were established in 2025 protecting 240.58 additional acres of land and bringing our total land protected to 7,115.65 acres. PTLT continues to work with the State of Maryland's Rural Legacy (RL) Program, St. Mary's County, and the Department of Defense Readiness and Environmental Protection Integration (REPI) Program to fund projects. PTLT continued working with landowners to place easements on properties within the Huntersville Rural Legacy Area in mid St. Mary's County Maryland. Five easements projects are in work and scheduled to close by December 2026.
    Expenses $74,134 · grants $18,000
  • Easement Monitoring: PTLT uses a volunteer team of monitors under the oversight of a volunteer Monitoring Coordinator and the Executive Director. This group identifies and evaluates potential issues on existing easements and completes, files, and distributes monitoring reports for each property. These reports are submitted to the easement co-holders and sponsors. This labor-intensive effort, while not consuming significant funding, is critical to ensuring that the conservation value of the properties is maintained and no easement violations occur. The Maryland Rural Legacy program grants PTLT funds to monitor properties for which they are co-holders.
    Expenses $2,475
  • Easement Compliance: Due in part to our thorough monitoring program, PTLT has had few easement compliance issues and tries hard to resolve these amicably with landowners. Our volunteer board members investigate, document, and resolve each issue. PTLT holds reserve funds received from the Rural Legacy program in a restricted account and holds insurance to address any violations that would require legal or technical expertise. PTLT continues to follow up with landowners on potential easement issues to help them address emerging problems in a timely manner. PTLT has a policy of requiring easement properties to be free of dumping prior to closing. This ensures our monitors can spot dumping changes on the properties easier. As part of easement compliance, PTLT is also keeping notes on inland erosion which has become an increasing issue in the Huntersville area after Hurricane Isaias in 2020. Examples of compliance issues that have been successfully addressed are vegetative buffer restoration, erosion remediation, and removal of material in violation of dumping restrictions.
    Expenses $11,545
  • PTLT received the Rural Legacy administrative fee from 4 easement completions in 2025, totaling $75,016.72. This is to be used for future acquisition, monitoring, compliance, and administrative costs.
    revenue $75,017
