Weir Farm National Historic Site was home to three generations of American artists. Julian Alden Weir, a leading figure in American art and the development of American Impressionism, acquired the farm in 1882. After Weir, the artistic legacy was continued by his daughter, painter Dorothy Weir Young and her husband, sculptor Mahonri Young, followed by New England painters Sperry and Doris Andrews.

Established in 1990, the park preserves the home of Julian Alden Weir and protects one of the last intact landscapes associated with American Impressionism. It is situated in the towns of Ridgefield and Wilton and helps preserve a significant portion of open space.The 68-acre park is located in the Southern New England Coastal Plains and Hills ecoregion in the southern part of Connecticut, and is within 25 miles of the Long Island Sound Atlantic coast. The park contains open fields, successional forest, and several wetland complexes and ephemeral surface streams. The ecological value of this small park is enhanced by adjacent forested land protected by the Weir Preserve and the Town of Ridgefield.

This area is part of the New England Upland section of the New England Province in the larger Appalachian Highlands. The region is characterized by north-south trending bands of rock reflecting a long history of Appalachian mountain building and ice age glaciation.


The goals of NETN's Vital Signs Monitoring in the park include:

  1. Determine the status and trends in selected indicators of the condition of park ecosystems to allow managers to make better-informed decisions and to work more effectively with other agencies and individuals for the benefit of park resources.
  2. Provide early warning of abnormal conditions of selected resources to help develop effective mitigation measures and reduce costs of management.
  3. Provide data to better understand the dynamic nature and condition of park ecosystems and to provide reference points for comparisons with other, altered environments.
  4. Provide data to meet certain legal and Congressional mandates related to natural resource protection and visitor enjoyment.
  5. Provide a means of measuring progress towards performance goals.

Because most protocols address multiple vital signs, the NETN program is organized around protocols, rather than vital signs. The drop-down lists below show monitoring and inventory activity, as well as all park briefs for Weir Farm NHS. The protocol drop-downs also show the relative vital signs that are addressed by each protocol.

Park Basline Inventories:

The Inventory and Monitoring Program provides guidance, funding, and technical assistance for parks to complete a set of 12 baseline, or "basic", natural resource inventories. These basic inventories are common to all parks with significant natural resources, and are intended to provide park managers with the minimum information needed to effectively manage the natural resources of their park. For more information, read the Fact Sheets for each of the inventories (PDF) by clicking here or on each individual inventory name.
