Head out with your camera and take photos of the plants and animals you see within Bull's Run. We are using the free iNaturalist app to gather data on the various species of plants and animals living at Bull's Run. All you need is your phone and the app.
How: Take close up pictures and it will directly input them into our project (location needs to be turned on). The newest release of iNaturalist makes suggestions for the species you are submitting.
Why: We use the data you collect to figure out if there are critters or plants living there that need extra protection, or if there are invasives that we need to work on clearing out.
When: Our BioBlitz runs all September and October. You can visit the arboretum anytime from dawn til dusk. Spend 5 minutes or 5 hours, this is totally up to you.
See the results: You can visit the project to see other peoples submissions at https://www.inaturalist.org/projects/fall-2025-bull-s-run-arboretum-bioblitz
Get the app or use a traditional camera: You will need to either download iNaturalist to your phone and have location turned on. Or, if you use a traditional camera you can submit online. Both the app link and the online submissions can be found at https://www.inaturalist.org/
Parking and Map: Free onsite parking and a trail map is located at the entrance.
