IEP Newsletter

The IEP Newsletter is a triannual publication that provides IEP program and science highlights as well as in-depth articles on scientific topics for resource managers, scientists, and the public.

IEP Newsletters are usually shorter articles intended for rapid communication. Articles in the IEP newsletter do not undergo external peer review. All primary research results should be interpreted with caution.

Upcoming Issue

The U.S. Fish and Wildlife Service is in the process of completing the Summer/Fall 2022 issue of the IEP Newsletter, and it should be ready for release by end of December 2022.

The next issue will be the Winter Volume 42, Issue 1, 2023, which will be edited by the California Department of Water Resources. Article submission deadline is February 15, 2023. If you would like to submit an article, contact Daphne Gille at Daphne.Gille@water.ca.gov.
