Natural Resource Monitoring at Weir Farm NHS

A fall day at Weir Farm NHS

 

Overview

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.

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.

Park Species Lists

Species lists are available from NPSpecies, the National Park Service's tool for documenting park biodiversity. Keep in mind that these species lists are a work-in-progress. Changes and updates are made as more species are shepherded through a rigorous vetting process. The absence of a species from a list produced with the tool below doesn't necessarily mean the species is absent from a park.

Species Attribute Definitions

Definitions

Occurrence

Occurrence values are defined below. One or more Occurrence Tags may be associated with each Occurrence value.

Present: Species occurs in park; current, reliable evidence available.

Probably Present: High confidence species occurs in park but current, verified evidence needed.

Unconfirmed: Species is attributed to park but evidence is weak or absent.

Not In Park: Species is not known to occur in park.

---

Occurrence Tags

Adjacent: Species is known to occur in areas near to or contiguous with park boundaries.

False Report: Species was reported to occur within the park, but current evidence indicates the report was based on misidentification, a taxonomic concept no longer accepted, or other similar problem of error or interpretation.

Historical: Species' historical occurrence in park is documented. Assigned based on judgment as opposed to determination based on age of the most recent evidence.

---

Abundance

Abundant:

• Animals: May be seen daily, in suitable habitat and season, and counted in relatively large numbers.
• Plants: Large number of individuals; wide ecological amplitude or occurring in habitats covering a large portion of the park.

Common:

• Animals: May be seen daily, in suitable habitat and season, but not in large numbers.
• Plants: Large numbers of individuals predictably occurring in commonly encountered habitats but not those covering a large portion of the park.

Uncommon:

• Animals: Likely to be seen monthly in appropriate habitat and season. May be locally common.
• Plants: Few to moderate numbers of individuals; occurring either sporadically in commonly encountered habitats or in uncommon habitats.

Rare:

• Animals: Present, but usually seen only a few times each year.
• Plants: Few individuals, usually restricted to small areas of rare habitat.

Occasional:

• Animals: Occurs in the park at least once every few years, varying in numbers, but not necessarily every year.
• Plants: Abundance variable from year to year (e.g., desert plants).

Unknown: Abundance unknown

---

Nativeness

Native: Species naturally occurs in park or region.

Non-native: Species occurs on park lands as a result of deliberate or accidental human activities.

Unknown: Nativeness status is unknown or ambiguous.

List Differences

The Checklist contains only those species that are designated as "present" or "probably present" in the park.

The Full List includes all the checklist species in addition to species that are unconfirmed, historically detected, or incorrectly reported as being found in the park. The full list also contains species that are "in review" because their status in the park hasn't been fully determined. Additional details about the status of each species is included in the full list.

The checklist will almost always contain fewer species than the full list.
