<br />5) 147,8 mile RR Seep, UTM coordinates N4023876, E350129,
<br />This site has no known recreation use, and low vulnerability to natural disturbance, There are
<br />small patches of primary vegetation which could only support a small KAS population, This
<br />site is located along the river conidor and accessible by existing game trails, There is two
<br />genera oflandsnails at this site, '
<br />
<br />6) Showerbath Spring (12,9 km up Kanab Crk), UTM coordinates: N4035700, E353000,
<br />This site has low recreation use, and low vulnerability to natural disturbance, This site could
<br />support a moderate-size KAS population A large patch of primary vegetation is located on
<br />the upper slope of an overhang, 3-m above the creek--the overhang is inaccessible without
<br />technical climbing gear, This site is located approximately 8 miles (12,9 km) from the river
<br />conidor, and accessible by a primitive trail, Overnight backpacking and technical climbing
<br />gear would be required
<br />
<br />7) Saddle Canyon (470 mile RR), UTM coordinates: N4024050, E4l8850,
<br />This site has high recreation use, but most visitors stay out of potential habitat (trampled veg
<br />at lower stream crossings) Abundant amount of primary vegetation could support a large
<br />KAS population, Potential release area was identified away from visitor trails, but still
<br />vulnerable to moderate natural disturbance, This site is accessed by a 3/4 mile (1,2 km) hike
<br />from the river conidor,
<br />
<br />Site Set 3, Sites rated as optimum or more desirable habitat, but with high management concerns:
<br />
<br />8) Thunder River (upper Tapeats Crk), UTM coordinates: N4028650, E369350,
<br />The entire site has moderate recreation use (limited to 35 campers/night at the Tapeats
<br />primitive campsite), but most visitors stay out of potential habitat (minor trampled veg at
<br />lower stream crossing), This area is one of the more popular backcountry recreation sites in
<br />the Canyon and NPS has significant management concerns with KAS introduction in this high
<br />use area, Numerous areas of primary vegetation could support a large KAS population,
<br />Potential release areas were identified away from visitor trails, and were less likely to be
<br />affected by natural disturbances, This site is accessed by a 2-mile (3,2 km) hike from the river
<br />conidor, There are eight genera oflandsnails existing at this site,
<br />
<br />9) Roaring Springs (N, Kaibab Trail), UTM coordinates N4006077, E406809,
<br />NPS has management concerns on water use restrictions--springs are the main water source
<br />for North and South Rim resorts, This site has high recreation use (> I 00 visitors/day), but
<br />most visitors stay out of potential habitat (some trampled veg along the creek and lower
<br />drainages), Numerous areas of 1'": 'f vegetation would support a large KAS population,
<br />Tbis site is accessed by a 4,5-mile (7,2 km) hike from the North Rim (North Kaibab Trail)
<br />There Me . least . genera oflandsnails existing at this site,
