Bio Blitz 2020

Thanks to the National Recreation and Park Association (NRPA) and The Scotts Miracle-Gro Foundation, the Dallas Park and Recreation Department is hosting a BioBlitz for the whole month of September in support of the Parks for Pollinators campaign.

Like Pokemon Go, we use iNaturalist, an app to take pictures of plants, insects and animals to see what wildlife is in the park and it provide us with more information about pollinators, which are essential to our ecosystem. This information will help us understand how we can better protect pollinators and other important wildlife in our community. Sign-up to participate in our BioBlitz in one or two ways!

Option 1: Collect as many different species all month long. The winner with the most gets a social media shout out. Join the “Dallas Park and Recreation Department: NRPA 2020 “Parks for Pollinators BioBlitz”” project on the iNaturalist app. 

Option 2: You could earn the title of Master Collector for your region! Visit one of the four regional events and race against the clock to collect the most observations. Click on the links to register for the event!

Adopt a Prairie Program


The Adopt-A-Prairie Program gives volunteer groups the opportunity to engage in the restoration and maintenance of the Blackland Prairie remnants found in Dallas parks. Fourteen prairie remnants totaling more than 162 acres have been identified, of which seven prairie parcels have been adopted by various groups. The prairie remnants were assessed based on their biological diversity, abundance of invasive species and overall management challenges. Learn how you or your organization can adopt a prairie by submitting an Adopt a Prairie Form.
