Why be a community scientist?

Listen to these words from Prof. Chroman – Field biologist, Certified CA Naturalist Instructor, science professor (or click here to read the transcript)

from the Urban Wildlife & Community Science Event with Prof. Chroman

What makes LA County Special?
“Located in a global hotspot for biodiversity, Los Angeles County is home to more than 4,000 distinct species of plants and animals, including 52 endangered species — more than any county outside of Hawaii.” – L.A. County’s biodiversity is on the map, thanks to UCLA researchers

WHY BE A COMMUNITY SCIENTIST? Prof. Chroman explains!
“[W]hen we join with you, and you join and engage in science with us, together we are capable of doing many magnitudes more for data collection, for study, for discovery, and for understanding. . . . [Y]ou, regardless of your degree, your age, your nationality, your ethnic group, your level of education, . . . you can help us understand something greater. Thank you for that.” – Prof. Lauren Chroman
