Many thanks to the trailblazing volunteers who made the Lincoln Park Conservancy’s pilot BioBlitz a big success. Twenty-one adventurous participants documented over 220 species in just one morning of observations! The data collected will be stored on iNaturalist, compiled, and used to inform future management decisions in and around the North Pond Nature Sanctuary with the goal of fostering wildlife and Chicagoans’ appreciation for it.
