Larry frequently cautions us about the different kinds of owl habitat, so I thought I’d post this handy table from the 2019 Forest Service CASPO conservation strategy.
Anonymous posted this link under “Topics of Interest”. It says it’s a proposed rule..
We, the U.S. Fish and Wildlife Service (Service), propose to list two distinct population segments (DPSs) of the California spotted owl (Strix occidentalis occidentalis), a bird species from California and Nevada, under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12- month finding on a petition to list the California spotted owl. After a review of the best available scientific and commercial information, we find that listing the Coastal-Southern California DPS as endangered is warranted, and that listing the Sierra Nevada DPS as threatened is warranted. Accordingly, we propose to list the Coastal-Southern California DPS as an endangered species under the Act and the Sierra Nevada DPS as a threatened species with a rule issued under section 4(d) of the Act (‘‘4(d) rule’’). If we finalize this rule as proposed, it will add these two DPSs to the List of Endangered and Threatened Wildlife and extend the Act’s protections to them.
She/he/they added .. “including a bunk 4(d) rule.”
Steve posted on the E&E news story here.
Claudia Elliott asked how this determination of “threatened” might change the management of giant sequoias and asked for our help and insights. Also, she asked what is a 4(d) rule?
It would be great if someone could explain the steps in the process from here on in, and especially how that ultimately gets translated into management direction, including where the public might be involved. Thanks!

We can also discuss 2ndLaws comment under Steve’s post. Hopefully it won’t be confusing to focus all the current CASPO discussion on this thread. Here’s 2nds comment:
This listing announcement is foreshadowing a aggressive program of “logging it to save it” even though it is well-established (thanks to the state-and-transition models used by carbon scientists) that the adverse effects of fuel reduction logging, plus unavoidable wildfire, are worse for spotted owls than the effects of wildfire alone, due in large part to the low probability that fuel logging will interact with wildfire during the brief period that treatments are effective.
Raphael et al (2013) used a state-and-transition model to explore the effects of landscape fuel reduction logging on spotted owls and found:
Active fuel reduction activities in moderate habitat contributed to substantial short-term (simulation years 0 to 30) population declines under the larger area, higher intensity scenarios. … The combination of BDOW interactions and high-intensity, larger-area treatments contributed to the most substantial NSO population bottlenecks. … It appears that management regimes that take out owl habitat through treatments (either current or potential future) do not reduce the amount of habitat that is lost to wildfire enough to make up for the habitats lost through treatments.
