Station #17 (cont'd) tussocked w/ Eriophorum vaginatum / Betula nana up to 30 cm high. ungodly walking. Some polygonized ground of Ledum / Rubus tundra.
Station #18 deep rolling foothills, ~ in the Saguan Uplands. Salix sp. flucht in fairly
prostrate form (up to 25 cm, very thick) along creek. Shapy overcapping rocks. Eriophorum vaginatum
tussock tundra away from creek basin w/ Ledum, Betula, Salix pulchra mixed in tussock
Station #19 braided
river terrace on coastal plain. Low thick mat of Salix [illegible] between ground braids.
Eriophorum vaginatum tussocks in upland dry mecca. Carex bigelowii + Salix laurata in slightly
wetter tussock, Betula nana, Carex, Ledum along edge of braided area.
Station #20 - heavily evaporated pond w/ lake edge, Carex aquatilis dominated [illegible] w/ Eriophorum
vaginatum angustifolium in margin also. Mounds + polygonized ground between small set of
ponds covered by Ledum - Rubus - Betula tundra. Upland tundra in the area largely
Eriophorum vaginatum. Low relief.
Station #21 very slight relief w/ shallow stream flanna beds moving toward Sag Basin, then
growing into deeper channel lined by Salix alaxensis and S. glauca. Upland is Eriophorum
vaginatum w/ Carex bigelowii and Salix laurata. On leeward of stream beds, dense stands
of Eriophorum angustifolium.
Station #22 - a broad area curssed from the road by a series of pond slabs, low Carex mainly,
polygonized w/ flow centers and low rivers, less than 30 cm high. Many roadside ponds covered by
accumming of drainage pulley. Carex saxatilis, Carex aquatilis in center of LCP's. Upland tundra is
Carex aquatilis, Carex bigelowii, Dryas, Salix reticulata, Salix laurata & Eriophorum vaginatum
For location of these sites see map on opposite page. For bird list see following two pages,
broken down by site. Overall general description:
Station 1-3 Picea glauca / riparian area ~ 600 m elevation
Stations 4-8 alpine tundra, riparian area 700 - 1100 m
Stations 9-18 foothills province w/ riparian sites 800-700 m
Stations 19-22 coastal plain, river floodplain ~ 200 m
Almost all areas contained some drainage system varying from Alnus fruticosa at (3 to [illegible])
