The federal wildfire occurrence database lists 56 fires within 5 miles of Mill Valley between 2001 and 2020, burning about 303 acres in total. 2 started naturally. None was 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:

• Amherst
• Amherst Center
• North Amherst
• Cushman
• East Hadley
• East Village

Every fire recorded in Hampshire County

Museums hold 10,103 specimens collected within 10 miles of Mill Valley between 1781 and 1975: 4,144 Animalia, 3,550 Plantae, 2,184 Fungi, 132 Chromista, 80 Protozoa, 12 Unrecorded, 1 Bacteria. 12 distinct Species records are shown. Collected by A V Osmun, A. Albee, A. Allen 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.
