What is a BioBlitz?

A BioBlitz is a period of biological surveying to record the living species within a designated area. It allows us to better understand what creatures are in our park at the time of the survey. It is interesting to learn what creatures use our very urban national park, but the project also has a larger significance. As human populations urbanize, gathering good data about what landscape features promote biodiversity in urban areas is more important than ever.
