The U.S. Fish and Wildlife Service (Service) proposes to revise the designated critical habitat for the northern spotted owl (Strix occidentalis caurina) under the Endangered Species Act of 1973, as amended (Act). Consistent with the best scientific data available, the standards of the Act, our regulations, and agency practice, we have initially identified, for public comment, approximately 13,962,449 acres (ac) (5,649,660 hectares (ha)) in 11 units and 63 subunits in California, Oregon, and Washington that meet the definition of critical habitat. In addition, however, the Act provides the Secretary with the discretion to exclude certain areas from the final designation after taking into consideration economic impacts, impacts on national security, and any other relevant impacts of spec...

Hotter temperatures are already occurring in New Mexico, he says, and scientists have been predicting the likelihood of more extreme weather events. "Well, we've certainly seen that here in New Mexico in the last five years-, droughts and floods," [Jim Norton] says, adding that scientists warning of climate change have indeed been correct. "It's not anymore just a future worry," he says, "It's an issue that's right here in front of us. All these places are seeing signs of diebacks of forests and woodlands-it's patchy in places, but it's starting to show up, and people are starting to see it," he says. Warmer temperatures in these places-considered "vulnerable" ecosystems because they are already arid-are pushing forests over the edge, Alien says. "We've started to see patterns emerge ...

If you read my last article, about tulips, you probably realize that I'm traveling. My peregrinations began in London. I've now worked my way south to the Mediterranean. With each stop, one of the first things that I look for is a botanical garden. Aside from my fascination with plants in general, these green sanctuaries give me a chance to become acquainted with the local flora, and in turn, the climate of the region.
