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

Get Ready for the City Nature Challenge this Earth Day @ the Natural History Museum of LA County

Members of Team Nature for All will be panelists at this event!

The City Nature Challenge is an annual competition between 100s of cities around the world that helps people better understand urban biodiversity by having them find and document nature in their community.

In celebration of Earth Day and in preparation for the 2021 City Nature Challenge, we’ll take a look at how community scientists are making a global impact by getting outdoors and looking closely at nature all around us. As a bonus, we’re offering an iNaturalist training so you’ll be ready to join the challenge!

*This event will be available with English and Spanish captions.

Decolonizing Knowledge from the Field with Sallqa-Tuwa

🔎🌿Dive into the field with Ph.D. candidate Sallqa-Tuwa as she draws on her experiences studying dragonflies and damselflies across borders.

📚Who’s name and knowledge gets left behind when scientific discoveries are publicized to the world? Register now for your spot in this important conversation!

Sallqa-Tuwa BondocGawa Mafla is a Pilipina-Ecuatoriana PhD candidate studying dragonflies and damselflies, known as the order Odonata, with Dr. Jessica Ware at the American Museum of Natural History and Rutgers University-Newark. Her research aims to answer questions regarding the dispersal, migration, and conservation of Tropical Odonata throughout species rich hotpots, such as her ancestral islands and mountains. An integral part of her work focuses on Indigenizing and Decolonizing Entomology, and Biology as a whole. Sallqa-Tuwa advocates for making space for Indigenous and Native naturalists, entomologists, and biologists to lead and collaborate on research projects undertaken in the Tropics and Global South, particularly across the Pacific Ocean and Ecuador, ultimately working for acknowledgement of Traditional Ecological Knowledge in a White-dominanted field.
