Rattlesnakes in the Scottsdale Preserve

When temperatures are between 60°F and 90°F, the cold-blooded reptiles of the Preserve will emerge from hibernation; this includes rattlesnakes. Rattlesnakes are an important part of the Preserve ecosystem and are a protected species. While you visit their natural habitat, it is important to remember a few tips to ensure a safe experience for you and your dog.

To avoid a close encounter with a rattlesnake in the Preserve:

  • Always stay ALERT and AWARE of your surroundings
  • Travel only on designated and posted trails
  • DO NOT TRAVEL OFF TRAIL
  • Do not place your hands or feet in places you cannot see
  • Always keep your dog(s) on a leash

If you encounter a rattlesnake on the trail:

  • PAUSE and quickly locate the snake
  • Move slowly and deliberately to a safe distance
  • Rattlesnakes will not chase you
  • DO NOT go off trail to avoid the rattlesnake; there might be another one in the brush
  • Provide a caution to other users in the area about the snake’s presence
  • Most importantly - LEAVE IT ALONE

If a rattlesnake bite occurs:

  • Carefully move away from the snake
  • Call 911 and get medical help as soon as possible
  • Remove jewelry and tight-fitting clothing in case of swelling
  • Immobilize the extremity and keep it below the heart
  • Remain calm and try to decrease total body activity

If bit by a rattlesnake in the state of Arizona, do not catch, try to identify or kill it. This can risk in a second bite and will waste time that needs to be focused on getting medical attention. Medical professionals treat all rattlesnake bites with the same antivenom, regardless of species.
