Why have they reached this list?
The main threat facing the Southeastern
beach mouse is continued development
along beaches. Development along
beaches can cause destruction or degradation to sand dunes limiting areas of habitat for the beach mouse, and
increasing fragmentation, leading to isolation of populations. Increased traffic on sand dunes is also a threat for the beach mouse, as the increased traffic damages vegetation on dunes that the beach mice depend on for food and shelter. Hurricanes also pose a risk to the beach mouse as they can cause damage and destruction to their sand dune habitat.
Their niche.
Primary dune vegetation described from southeastern beach mouse habitat includes sea oats, dune panic grass, railroad vine, beach morning glory, salt meadow cordgrass, lambs quarters, saltgrass, and camphor weed.

Coastal strand and inland vegetation is more diverse, and can include beach tea, prickly pear cactus, saw palmetto, wax myrtle, rosemary, sea grape, oaks and sand pine.

EFFORTS TO SAVE THEM.
- Most of the remaining habitat for the species is on public land,
- and management efforts have centered on
- maintaining suitable habitat.
- The long- term persistence of the southeastern beach mice depends
- on reintroducing into areas.
