CHUGWATER, Wyoming (AP) -- Amy and Steve LeSatz want to be able to teach their clients the finer points of riding and roping without having to trailer their animals 25 miles to the nearest public indoor arena whenever the weather turns miserable.

But the LeSatzes aren't able to build their own riding arena. The only decent site on their property in southeastern Wyoming lies within 300 feet of Chugwater Creek, and building there is far too expensive because of Endangered Species Act restrictions intended to protect the Preble's meadow jumping mouse.

"The mouse that doesn't exist," Amy LeSatz noted drily.

After six years of regulations and restrictions that have cost builders, local governments and landowners on the western fringe of the Great Plains as much as $100 million by some estimates, new research suggests the Preble's mouse in fact never existed. It instead seems to be genetically identical to one of its cousins, the Bear Lodge meadow jumping mouse, which is considered common enough not to need protection.

The new research could lead to loss of the Preble's "threatened" status and removal from Endangered Species Act protection. The U.S. Fish and Wildlife Service plans to decide that question in December.

"We're trying to be deliberate in our work, trying to get the best science we can and review of the science we do have, in making this decision. Because we know it is very important and serious to a lot of people," said Ralph Morgenweck, regional director of the U.S. Fish and Wildlife Service in Denver. "But I would also say it is a lot more complicated than what it appears to be."

Far from closing the book on the Preble's mouse, the research by the Denver Museum of Nature and Science has opened a new volume of questions -- including what to do about landowners who have been affected, whether the Bear Lodge mouse also needs protection and whether the Endangered Species Act itself needs changes.

"If we've shown that the mouse doesn't exist, what happens to all that has been set aside? Because that's been a huge economic burden," wondered Brian Garber, assistant director of governmental relations for the Colorado Contractors Association.

Meadow jumping mice live near streams, and nearly 31,000 acres along streams in Colorado and Wyoming have been designated critical mouse habitat. That includes large parts of the Colorado Front Range, which over the past several years has been rapidly developed with strip malls and housing subdivisions.

Front Range developers and local governments have had to set aside a lot of land to protect the mouse, though if protections are lifted, that does not mean all that land can be developed. Subdivisions, for example, have roads, sewers, water lines and other infrastructure designed for a certain number of homes. In many cases, adding more homes is not feasible.

But developers would like to see restrictions, which can be both expensive and annoying, ended for future development. In one Colorado Springs, Colorado, subdivision, for example, the restrictions include a requirement that cats be kept on leashes.

In rural areas, protecting the mouse has meant telling ranchers they cannot clear weeds out of their irrigation canals, reducing the amount of water that gets to their hay fields in the middle of summer. They are also restricted in how they can allow their animals to graze along streams, another regulation the LeSatzes have to work around.

On top of that, the mouse also has blocked the construction of reservoirs amid a five-year drought in the Rocky Mountains.

"The bottom line is, it has been a wonderful tool for environmental groups to try to stop things," said Kent Holsinger, attorney for Coloradans for Water Conservation and Development, which has asked the Fish and Wildlife Service to remove the mouse from federal protection.

Indeed, environmental groups are now calling for Endangered Species Act protection for the Bear Lodge mouse. They say that subspecies -- which had been thought to be limited to the Black Hills of South Dakota and Wyoming but now appears to exist as far south as Colorado Springs -- suffers from the same habitat degradation.

The Preble's mouse was established as a distinct subspecies by a study 50 years ago that was cited in the 1998 decision to declare it threatened.

The man who did the 1954 study, Philip Krutzsch, now a professor emeritus with the University of Arizona, had examined the skulls of three mice and the skins of 11 others. It was an acceptable level of scrutiny at the time but "an extremely weak inference by today's standards," said Rob Roy Ramey II, curator at the Denver Museum of Nature and Science and project leader on the new DNA research that overturns Krutzsch's conclusion.

Ramey and his colleagues analyzed mitochondrial DNA, the cell's genetic code, from several of the 12 subspecies of meadow jumping mice, which range from the Pacific to Atlantic and as far south as Georgia.

They also repeated Krutzsch's skeleton measurements, using more specimens -- mainly from university and museum collections -- and more accurate tools. They concluded that the Preble's mouse is actually a Bear Lodge meadow jumping mouse, not a separate subspecies.

Despite being reversed, Krutzsch endorses the new research and its conclusion: "It's at the cutting edge of science today and it's very thorough and comprehensive. I think it clearly defines what is true biologically."

But, inadequate as it may have been, Krutzsch's old study was the best science that had been done up until the listing of the Preble's mouse. The Endangered Species Act only requires that species protection be based on the best available science -- not the best possible science.

Ramey's DNA study seems likely to usurp Krutzsch's as the best science to date. But environmental groups are not willing to surrender.

They point out that Ramey's study has not been peer-reviewed. They also highlight criticism from Ramey's scientific peers that he did not compare the nuclear DNA, the molecular building blocks of entire organisms, of the mice subspecies -- something Ramey has begun examining at the Fish and Wildlife Service's request.

And Jeremy Nichols, spokesman for the Biodiversity Conservation Alliance in Laramie, Wyoming, attacked Ramey's impartiality.

"Ramey has a clear anti-Endangered Species Act agenda," he said. "He's been testifying in Washington, D.C., in front of committees headed by members of Congress who would like nothing better than having the Endangered Species Act thrown away."

Ramey, who has studied endangered species more than 20 years, did testify in April before a House subcommittee that the Preble's mouse shows how the Endangered Species Act needs major changes. But he said his advocacy is for better science to bolster the legitimacy of endangered species status.

"I care about the act. I care about habitat. And that's why it's important to lay the issues out on the table," he said.

Ramey thinks the question of to-list or not-to-list should be based on the most up-to-date science and modern techniques. He also wants more science used in deciding the details of protecting species.

"You need to convince me that the hypothetical threats are real and observable and quantified, and set up a testable hypothesis," he said. "Otherwise it's opinion, and I don't trust opinion."

The LeSatzes, meanwhile, say the Preble's mouse has nearly caused them to throw in the towel several times. But they hope they will at last be able to build their riding arena -- by doing much of the design work and construction themselves -- if the regulations are lifted.

"A tiny little mouse comes in and changes your whole perspective," Amy LeSatz said. "I've had more of an education in endangered species than I've ever wanted."

Another glareing example why, gumint belongs, just barely, in Washington and far from people's lives and property.

Let's keep prayer out of schools while we're at it.

The whole enviromental protection act is such bull chit
why save a mouse? for what purpose?
other countrys see us and laugh at stuff like this.

[Rufus Rhastus J]

Seriously, I wonder what other countries really think about laws like this.

Dennis must not be a hunter. Fish and wildlife make sure there are good deer seasons etc.

Not every application of the laws protecting our environment makes sense, but they are not stupid.

Other countries have even tougher laws on the enviorment.

Germany is far worse, and so is England. Before long they will grant companion animals equal rights....dont laugh, Germany just passed some really rediculous animal rights legislation....

I am a hunter and I think the protection act is a bunch of bunk -- why protect a mouse or a bug they server no purpose and its just a tool for tree huggers to use to annoy people and spend tax dollars. Look at how they wiped out the complete ecomony of Oregon over the Spotted Owl -- In Oregon most people will shoot a spotted owl on site because of what they have done to peoples lives.

You must have gotten a gentleman's "C" in biology.

can't remember what I got that was Highschool
