The decision by the U.S. Fish and Wildlife Service comes after a lawsuit by multiple conservation groups required the government to reassess a Trump administration decision not to protect the brown and white birds.
The habitat of the medium-sized brown owl with white spots on its head and chest and a barred tail is under serious threat from current logging practices and climate change, including increased drought, disease and more extreme wildfires.
The only available demographic data on spotted owls living in coastal and Southern California was collected in San Bernardino National Forest and shows a decline of 9%, the federal wildlife service said.The Sierra Nevada population shows declines ranging from 50% to 31% percent in some areas, the agency said.
Augustine said he planned to use the 60-day public comment period to push for more protections for the California spotted population in the Sierra Nevada.

Long-Term Effects of the Cleaner Fish Labroides dimidiatus on Coral Reef Fish CommunitiesCleaning behaviour is deemed a mutualism, however the benefit of cleaning interactions to client individuals is unknown. Furthermore, mechanisms that may shift fish community structure in the presence of cleaning organisms are unclear. Here we show that on patch reefs (61–285 m2) which had all cleaner wrasse Labroides dimidiatus (Labridae) experimentally removed (1–5 adults reef−1) and which were then maintained cleaner-fish free over 8.5 years, individuals of two site-attached (resident) client damselfishes (Pomacentridae) were smaller compared to those on control reefs. Furthermore, resident fishes were 37% less abundant and 23% less species rich per reef, compared to control reefs. Such changes in site-attached fish may reflect lower fish growth rates and/or survivorship. Additionally, juveniles of visitors (fish likely to move between reefs) were 65% less abundant on removal reefs suggesting cleaners may also affect recruitment. This may, in part, explain the 23% lower abundance and 33% lower species richness of visitor fishes, and 66% lower abundance of visitor herbivores (Acanthuridae) on removal reefs that we also observed. This is the first study to demonstrate a benefit of cleaning behaviour to client individuals, in the form of increased size, and to elucidate potential mechanisms leading to community-wide effects on the fish population. Many of the fish groups affected may also indirectly affect other reef organisms, thus further impacting the reef community. The large-scale effect of the presence of the relatively small and uncommon fish, Labroides dimidiadus, on other fishes is unparalleled on coral reefs.
