BioBlitzs are events that focus on finding and identifying as many organisms as possible within a specific area over a short period of time.  They rely on the expertise of biological specialists and scientists, but are also a great way to get out in nature and see what is found.  Preservation Parks of Delaware County is hosting a BioBlitz on Friday, Sept. 7th - 8th at Deer Haven Park.  Visit the Preservation Parks Website for more information, or to learn about all they have to offer.
