florida gators... never threatened!

If you ain't a Gator, you should be! Alligators (and endangered crocs) are important indicator species atop their food chains, with sensitivity to pollution and pesticides akin to humans. See ESA blawg. Gator blood could be our pharmaceutical future, too. See ESA musing.

Follow the truth.

"This institution will be based on the illimitable freedom of the human mind. For here we are not afraid to follow truth wherever it may lead, nor to tolerate any error so long as reason is left free to combat it." -- Thomas Jefferson to William Roscoe, December 27, 1820.

73 Fed. Reg. 39790 (Thursday, July 10, 20087)(Department of the Interior; Fish and Wildlife Service; 50 CFR Part 17; Endangered and Threatened Wildlife and Plants; Final Rule To Amend the Listing for the Preble’s Meadow Jumping Mouse (Zapus hudsonius preblei) To Specify Over What Portion of Its Range the Subspecies Is Threatened; Final Rule)

Meadow jumping mice (Zapus hudsonius) are small rodents with long tails, large hind feet, and long hind legs. They are primarily nocturnal or crepuscular (active during twilight), but also may be active during the day.  High-use habitat areas for Prebles tended to be close to creeks and small drainages, and are positively associated with the percentage of shrubs, grasses, and woody debris.   Photo from FWS.

SUMMARY: We, the U.S. Fish and Wildlife Service (Service/USFWS), under the authority of the Endangered Species Act of 1973, as amended (Act), amend the listing for the Preble’s meadow jumping mouse (Zapus hudsonius preblei) (Prebles) to specify over what portion of its range the subspecies is threatened. Based on the best scientific and commercial data available, we have determined that the Prebles is a valid subspecies and should not be delisted based upon taxonomic revision; the subspecies is not threatened throughout all of its range; and the portion of the subspecies’ current range located in Colorado represents a significant portion of the current range where the subspecies should retain its threatened status. This determination is based on a thorough review of all available information, which indicates that Prebles’ populations in Wyoming are more widespread and threats to the subspecies less severe than those known at the time of listing, but that in Colorado the Prebles is likely to become endangered within the foreseeable future. This rule is effective August 11, 2008.

NOTEWORTHY EXCERPT: We conclude that the loss of the Prebles within Colorado would result in a decrease in the ability to conserve the subspecies. We have determined that, based on its importance to the conservation of the subspecies and because it contributes meaningfully to Prebles’ representation, resiliency, or redundancy, the Colorado portion of the range constitutes a significant portion of the subspecies’ range as described in the Act.
