Grassland Habitat Monitoring for Wintering Chestnut-collared Longspur

Arizona
2025
Overview

For over ten years, the Tucson Audubon Society has collaborated with Audubon Southwest through the Important Bird Area (IBA) program to develop a protocol that protects the Chestnut-collared Longspur (Calcarius ornatus; CCLO). They monitored the CCLO population through volunteer-led in-person surveys and audio recordings, analyzed the conditions of cattle tanks, and documented the presence of invasive Lehmann’s lovegrass.

Methodology

Approach

This project implemented a comprehensive grassland conservation and restoration restoration approach, combining scientific research with community engagement and traditional ecological knowledge.

Implementation Steps

  1. Baseline assessment and site selection
  2. Stakeholder consultation and community engagement
  3. Design and planning phase with technical experts
  4. Implementation with local workforce training
  5. Monitoring and adaptive management

Timeline

The project was implemented over a 2-year period, with ongoing monitoring and maintenance continuing beyond the initial implementation phase.

Increasing Habitat Connectivity and Permeability for Pronghorn in Southeastern Arizona

Arizona

The Southeast Arizona Collaborative Grassland Workgroup was created in 2010 to develop a southeastern Arizona Regional Pronghorn Strategy to increase pronghorn population numbers, distribution, and connectedness. The project aimed to improve habitat connectivity and access to available water sources through strategic fence modifications, and improve habitat quality through grassland restoration and addition of water sources.

Ecological Benefits of Compost for Rangeland Plant and Soil Health

New Mexico

The use of organic amendments such as compost is a potential tool for grassland restoration. Compost additions can promote soil water retention and plant productivity, and reduce erosion. Cost is a major barrier to this technique. This study worked to understand and quantify the ecological benefits of compost addition, in the hopes of promoting its economic viability as a restoration method.
