Dos & don'ts
Local etiquette that keeps wildlife wild.
Do
- Hike Ramsey Canyon for hummingbird diversity.
- Report jaguar or ocelot sightings to Sky Island Alliance.
- Keep distance — use zoom or binoculars, never bait animals closer.
- Stay on marked trails to avoid trampling nests, burrows and plants.
Don't
- Don't drive off-road in tortoise habitat.
- Don't collect wildflowers — most are legally protected.
- Never feed wildlife — human food changes behaviour and shortens lives.
- Don't share exact locations of nests, dens or rare species online.
