Dr. Stephen Goldberg, a frequent amphibian contributor to California Fish and Wildlife, included an interesting note on the reproduction of Cascades frog, a candidate species for listing under the California Endangered Species Act (CESA). Another frequent contributor, Dr. Vernon Bleich (former Editor-in-Chief of this Journal) provided two submissions—a note on Woodhouse’s toad locations suggesting that major storm events have likely facilitated expansion of the species in California as well as an obituary for Robert L. Vernoy, a long- time biologist for the Department. Dr. Travis Longcore, from the University of California, Los Angeles, and his co-authors presented a thought-provoking essay on Monarch butterflies and their use of non-native trees when overwintering in California. Next, Dr. Barbara Clu- cas, from the well-known Wildlife Department at Humboldt State University, developed, along with several of her students, a new method for monitoring raptors in agricultural areas using camera traps and artificial perches. And finally, Dr. David Boughton of the National Marine Fisheries Service at the Southwest Fisheries Science Center, provided a review of the striped bass in coastal California—a non-native species introduced in California in the late 1800s for sport fishing. Our editorial team gained another excellent member recently. Mario Klip joined the Department in 2012 with the North Central Region. He obtained a PhD in Environmental Sciences Policy at the University of California, Berkeley in 2018, with a focus on black bears, and he completed his master’s in biology at Sonoma State University in 2012. Ma- rio had a very different career before joining CDFW; prior to working with wildlife and conserved lands, he worked in the IT industry, and he holds a bachelor’s in international management and marketing and master’s in in management accounting from the University of Amsterdam. He moved from the Netherlands to California for various projects and ended up in Silicon Valley and held various senior positions before drastically change careers to pursue a life-long passion focused on wildlife. He is passionate about conducting applied research to better inform wildlife and land use decisions. We also had a wonderful guest editor for the raptor manuscript in this issue. Carie Battistone received two degrees from the University of California, Davis: a bachelor’s in Wildlife Biology and a master’s in Avian Ecology. She currently serves as CDFW’s State- wide Raptor Conservation Coordinator, a position she has had for over 10 years. In this coordinator role, Carie manages CDFW’s efforts related to conservation, policy, regulation, and research for raptor species in California. A reminder that many of the Journal’s Special Issues will be coming out this year! We have explored the impacts of fire, cannabis, and human recreation on fish and wildlife resources. The recreation issue came out in April, and the others will be out later this sum- mer. Additionally, we are now accepting submissions for two new special issues—one on the California Endangered Species Act (CESA) and one on Human-Wildlife Interactions.

Many artificial raptor perches have been constructed as a solution to this deficiency, however, monitoring the benefits of these perches has proved challenging. We developed a method using artificial perches and camera traps mounted on poles that allows for 24-hour monitor- ing of perch utilization. We tested
