## Ecology

### Habitat

Discus catskillensis is found in cooler climates and moist deciduous forests, at wooded ridges and slopes, around logs, stumps, rock talus, and dead leaves, or in small openings, in hedgerows, farms, yards and old fields where there is cover.[3][4]

### Range

It is native to the northeastern United States, particularly the Catskill Mountains and surrounding regions. It is rated by NatureServe as Secure in New Brunswick, Apparently Secure in Ontario and Manitoba, Vulnerable in Virginia and Pennsylvania, Critically Imperiled in West Virginia and Maryland, and Presumed Extirpated in Kentucky, Indiana and Mississippi.[1]

### Diet

Like other members of the family Discidae, this snail feeds on fungi and decomposing plant material, playing a small but important role in forest nutrient cycling.
