August
(cont'd)
STATION #8 (cont'd). Lowland by river low stature Salix alaxensis
STATION #9 Toolik LAKE - large (<1 mi diameter fresh water lake surrounded by
upland tundra, rolling foothills. Upland tundra in Baldy Ridge area w/ Betula nana, Dryas, Arctostaphylos
Carriaga (Bryophyta) many ericaceae in nearshore zone.
Station #10 - Broad stream valley w/ outcrops of rocks downhills slope. Upland tundra above foothills on
Walker-Walker site #10. Dryas + Arctostaphylos dominants exposed knolls; Carex bigelowii tundra in more
moist site, slightly mossy w/ Vaccinium vitis-idaea, V. uliginosum, Ledum, Salix pulchra. Larger Salix
sp along creek basin in narrow band up to 1m high.
Station #11 - Kuyanuk River crossing - deep broad valley of extensive willow thickets up to 1m high, very
thick (i.e. impenetrable)
Station #12 - Tussock upland tundra of Eriophorum vaginatum, then some polygonized ground w/ good stands
of Ledum, Betula, Ribes, Vaccinium vitis-idaea.
Station #13 - High bluff overlooking Sag River valley. Knolls covered w/ Dryas-Arctostaphylos; Carex bigelowii
dominating upland tundra w/ much Dryas mixed in. Polygonum bistorta also evident. Some willow thicket
along Upper Oksu Kuyik Creek; lake area with a few ericaceae set in deep basin.
Station #14 - Disturbed pond w/ altered drainage due to close pipeline/haul road. Undisturbed site in area
thick will developed tussock tundra w/ Eriophorum vaginatum, Betula nana, Salix pulchra etc.
Pond site a thick Carex marsh w/ bare edge due to receding water, other ericaceae also present.
Pond ~30m across. Eriophorum angustifolium well developed in winter road passage site. Low overall relief.
Station #15 - Bluff overlooking Sag River + river terrace: bluff will develop E.vag/Betula kendra; side
of bluff varies from prostrate Arctostaphylos tundra to thick Salix sp w/ strong understory of Betula, Vaccinium uliginosum
thickets running down more than 50cm. At base of bluff polygonized Carex-Arctopanacodus marsh in centers with
very slightly higher river, then along drained creek good willow growth up to 1.5m in some sites.
Station #16 - Disturbed pond created by pipeline from wet area in Erioph. vag. tussock tundra
some Carex marsh must have been present but not exclusive (20m x 100 m).
Station #17 - Creek basin lined w/ Salix up to 2.5m high, broadening into slight fan - reminiscent of
crevatura U.S. creek bottom. B. Rangifer and B. Moose present. Upland area very heavily
