The federal wildfire occurrence database lists 36 fires within 5 miles of Derwent between 2009 and 2020, burning about 81 acres in total. None started naturally. 2 were recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Pleasant City
• Buffalo
• Fairview

Museums hold 295 specimens collected within 10 miles of Derwent between 1875 and 1975: 133 Fungi, 102 Animalia, 56 Plantae, 2 Unrecorded, 2 Protozoa. 12 distinct Species records are shown. Collected by Adams, W. (William), Adams, W. (William), Trautman, M. B. (Milton Bernard) et al., Adams, W.; Adams, S. and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1064534.
