Native Plants & Wildlife

It wasn't very long ago that Mansfield was a tiny stop sign in the wild, wild west. Even with all the growth, a trip to your nearest park will prove it's still got a little bit of that wild left!

Please do not attempt to touch, pet, feed or catch any wildlife you see. You are a visitor in their home and they should be left alone! If you are concerned about a possible dangerous animal, please contact Animal Care & Control at (817) 276-4799.

Where to Look

Your best chance of seeing wildlife is along the Walnut Creek Linear Trail or in the larger parks with more undeveloped space, like Elmer W. Oliver Nature Park, Katherine Rose Memorial Park and Town Park. If you spot a little creature on your next visit, please take a photo and share it with us on social media (@MansfieldTxParks on Facebook or Instagram) so we can all enjoy your discovery!
