About this file

This document is an Excel file titled "Exhibit 2a All Rare Plants List" that contains a list of rare plant species found in Idaho. It provides detailed information on each species, including the scientific name, common name, INPS status, IDNHP rank, range, number of occurrences, county, habitat, threats, and recommendations.

The key details from this document are:

  • The list contains 225 rare plant species found in Idaho, including information on their conservation status, distribution, habitat, and threats.
  • Many of the species are considered rare (INPS status of "RARE") or have a state rank of S1 or S2, indicating they are critically imperiled or imperiled in Idaho.
  • Threats to the rare plants include development, grazing, invasive species, climate change, recreation, and other human activities.
  • The document provides recommendations for managing and conserving these rare plant species, including adding them to special status lists, monitoring populations, and addressing specific threats.

This information may be relevant to the Invasive Species/Rare Plants Vegetation Management Services IDIQ contract opportunity, which seeks services to manage invasive species and rare plants on National Forest lands.
