The Many Unique Species on Mt. Graham

There are at least 18 plants and animals unique to the world that
have evolved on Mt. Graham's Galapagos-like, "sky island" Hudsonian
forest summit ecosystem. These include three mammals, three flowering
species, three unique mollusks and many arthropods (see below). They
are adapted for survival to subzero boreal forest winters. Many other
species on Mt. Graham remain to be identified.

The U.S. Fish and Wildlife Service (USFWS) pointed out that the
telescope project was located in the heart of the "best" 472 acres of
the Mt. Graham Red Squirrel's critical habitat, namely, the flattest,
most fully canopied portion of Mt. Graham's summit Hudsonian (boreal)
forest. The USFWS Biological Opinion states that the 8.6-acre, 3-scope
project "permanently destroys" 47 acres or 10% of the squirrel's "best"
472 acres of intact, canopied habitat through indirect and direct
ecological effects. Indirect effects include habitat desiccation and
fragmentation of the adjacent forest. Would one destroy 10% of
America's best farmland, let alone 10% of the best habitat of one of
the most endangered mammals in North America?

Prior to the construction of the UA's brand new, all-weather
telescope access road to the summit telescope area, this was a
pristine, undeveloped Hudsonian forest gem and cradle of evolution. It
was unaffected by the various prior human developments farther down at
the lower elevations on the mountain such as the old, rustic summer
cabins, antennas, campgrounds, etc. That the astronomers habitually
pretend to confuse the pristine, summit boreal forest with the
developed, lower altitude, non-boreal forest ecosystems on the
mountains shows their unwillingness to address in a scholarly and
scientific manner the simplest facts of this mountain's biogeography.
