Show Patton, J. L. 2015 Great Basin National Park 21-25 August 2015 Using the midpointofthis line to designate coordinates and elevation for the locality, this would be: Lehman Cave, Snake Range, Great Basin National Park, White Pine Co.., Nevada 6969 ft 39. 00348°N 114. 22108°W 14’ precision WGS84 datum This trapline goes up fairly steep (ca. 45° aspect), north-facing slope for the first 7 stations and then extendsacrosstherelatively flat top ofthe hill until its end. The habitat is uniform pifion-juniper woodland with the same two species of conifers as on trapline 4; the canopy coveris similarly variable, from 25 to 50%, and thus in both aspects this trapline is similar to the conditions of trapline 4. The underlying substrate, however, is quite different and, consequently, so is the understory community. The soil is the same loamy-sand covered by very abundant small rocks, from pebble to sizes < 5 cm. There are no limestone outcrops anywhere along the line exceptat the initial part of the upward slope from stations 1 and 2,andin this respect trapline 5 is visibly quite distinct from line 4. The understory itself is open, largely bare ground, with only the very occasional clumps of Purshia, Artemisia, Ephedra, and Opuntia; only one small clump of Pterophytum were encountered along the line; forbs and grasses were similarly rare, all of short stature, and completely dried at this time of the year. Otherwise, in comparisonto line 4, this is a more open habitat at ground level with few plants of any kind or height, few to no large outcrops or boulder-sized rocks, but more fallen limbs and other woodydebris. |
