Species Distribution in Massachusetts


Federal Rank: None

Massachusetts State Rank: Endangered

Habitat Description

Open to partially shaded sites of disturbance-dependent habitats, such as grassland sand plains, pine barrens, pitch pine-scrub oak barrens and dry open woodland edges. Substrate is dry sandy or clay soil.

Threats to Survival

Declining habitat quality and natural succession resulting in over-shading.

Actions Recommended to Ensure Survival

A vegetation management plan should be constructed if native and invasive plant species become too aggressive and over-shade the habitat. Management for this can include mowing, tree removal, prescribed burning or targeted invasive plant removal. Areas that see heavy recreational use should be carefully monitored for plant damage or soil disturbance.
