JB MDL Military Conservation Partnership Award & CWF Projects

by Meaghan Lyon, Wildlife Biologist

Earlier this year, the U.S. Fish and Wildlife Service (USFWS) awarded Joint Base McGuire, Fort Dix, and Lakehurst (JB MDL) with the Military Conservation Partnership Award for outstanding efforts to protect both State and Federally listed threatened and endangered species. The award recognizes significant natural resource management achievements by military installations, particularly the conservation of important wildlife and their habitats through cooperative work with USFWS and other partners. CWF has been a major partner on many projects at JB MDL spanning from grassland habitat restoration and monitoring, myotis bat surveys and tracking, and a full mammal inventory.

Over the past six years, long term efforts have been ongoing to expand and protect grassland habitat at the McGuire Airfield. So far, roughly 600 acres have been restored to native warm season grasses with another 100 acres to be completed by next spring. The planting of species like little bluestem, sideoats grama, and blue grama has helped to create grassland bird nesting habitat. Grassland bird surveys are conducted each summer to monitor success of species like upland sandpiper and bobolink.

2022 Upland Sandpiper Survey Results

by Meaghan Lyon, Wildlife Biologist

The results are in! It wasn’t a great year for upland sandpipers at the McGuire Airfield. Numbers of breeding pairs at this location have decreased to an estimated two pairs. Numbers can be variable from year to year so there is still hope for better news in 2023.

Upland sandpipers typically require a minimum of 100 acres for breeding habitat and so large expanses of open, grassy land is a high priority. Over the past five years, long term efforts have been ongoing to complete a large-scale grassland restoration at the McGuire Airfield. So far, roughly 500 acres have been converted to native warm season grasses with another 100 acres to be completed by next spring. Our goal is to help create and maintain grassland bird nesting habitat for Upland sandpipers and other species.

Ongoing Grassland Restoration Efforts Improve Conditions for Grassland Nesting Birds

by Meaghan Lyon, Wildlife Biologist

Over the past five years, long term efforts have been ongoing to complete a large-scale grassland restoration at the McGuire Airfield. So far, roughly 500 acres have been treated and seeded to encourage the growth of native warm season grasses with another 100 acres to be completed by next spring. The planting of species like little bluestem, sideoats grama, and blue grama has helped to create grassland bird nesting habitat and conserve existing habitat, while accommodating necessary airfield procedures and safety.

Keeping the vegetation on the airfield short is important to ensure airport safety and to achieve that goal, the fields must be mowed. When the vegetation reaches 12-14 inches, the area is mowed back down to 7 inches. The vegetation before the start of the restoration project was a mix of native and non-native woody, forb, and grass species, with some plants growing at a faster rate than others. The quicker these plants grow, the more frequent mowing must occur. It’s for this reason why native warm season grasses were planted, which have a slower growth rate and tend not to grow more than 12-14 inches. By planting these species and reducing mowing frequency, the grassland birds have less disturbance and human impacts on their nesting season.

This work is done in cooperation with the USFWS New Jersey Field Office, and grassland bird surveys are completed throughout the summer to monitor success. Stay tuned to learn more about our grassland bird results for the 2022 breeding season.

Vegetation must be mowed when grasses exceed 12 inches.
