The Natural Resource Condition Assessment (NRCA) Program provides framework, funding, and publishing support to parks to aid in the synthesis and documentation of natural resource conditions. Condition assessment reports are a tool to describe selected park resources, and record a snapshot of their current condition, identify trends, and identify potential or current threats and stressors. Understanding the condition and trend of natural resources is key for parks and NPS planners to appropriately prioritize and allocate stewardship resources.

Traditional NRCA Report: 2016
In an effort to better understand the natural resources and processes within this Historic Site, a Natural Resource Condition Assessment was conducted and published in 2016. Available data and the needs of the National Historic Site were evaluated, and the following resources were chosen to be evaluated:
- Air and climate |
||
- Geology and soils |
||
- Water |
||
- Biological integrity |
||
- Human use |
||
- Landscapes |
The indicators within each of these resources were mixed in condition ratings. Seven indicators were in good condition; ten indicators were in a condition of moderate concern; ten indicators were in a condition of significant concern; and four indicators were not assigned a condition score, due to lack of data or undefined metrics. Overall, assessment of natural resource condition at Weir Farms National Historic Site reflects condition supportive of a wide variety of native flora and fauna within the park ecosystems. Resource managers will continue to manage wetlands, forests, and native vegetation and to steward all other resources found within the park.
