The Central Valley has undergone massive habitat change in the past century, creating a heterogeneous landscape. Many researchers lack the ability to undertake long-term biological monitoring on restoration projects and to measure long-term success, particularly on understudied private lands. What’s a researcher to do?

To find out, join Yolo Audubon’s virtual January Members Meeting to hear featured speaker, Danielle Fradet, describe one possible solution, Automated Recorder Units, (ARU). Ms. Fradet is the first recipient of the Yolo Audubon Small Grant Program. 

Automated Recorder Units can be used to saturate a large landscape with time dependent surveys of birds, thus gathering more data on bird presence than traditional point counts. Ms. Fradet’s study tests if the ARU method can be applied on a smaller scale for long-term monitoring on specific restored sites. Her work was done on a ranch with heterogeneous habitat of rice, wetlands, and riparian systems.

Danielle Fradet is a recent graduate from UC Davis, earning a B.S. in Wildlife, Fish, & Conservation Biology. Danielle grew up in Southern California and first found an interest in wildlife watching Animal Planet on TV. However, she discovered her passion for birds in her first year of college while interning at the UC Davis Museum of Wildlife and Fish Biology (MWFB). Today, Danielle works in the MWFB, doing field work with small mammals, birds, bats, and herpetofauna in the Sacramento-San Joaquin Delta.
