Using a 20-year dataset, we found that a common kelp forest fish in southern California has periodic peaks and troughs in recruitment, with a ~6 year cycle. Then, using age-structured population models we found that whether a new marine protected area was put in place during a peak or a trough either enhanced or delayed (respectively) post-protected population increases. That makes it more difficult to determine whether the reserve is successfully enhancing the population. Helpfully we also found that using before-after control-impact designs for monitoring helped mitigate this issue.<\/p>\n\n\n\n<p>This project is a product<a href=\"https:\/\/www.piscoweb.org\"> of the  Partnership for the Interdisciplinary Study of Coastal Oceans<\/a>, and we hope it will inform the assessment of marine protected areas in California and Oregon in 2023.<\/p>\n\n\n\n<p>Email <a href=\"mailto:will.white@oregonstate.edu\">will.white@oregonstate.edu<\/a> if you would like a copy of the manuscript.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hopf et al.
