| General Description |
Mature white spruce spruce stand on a south-facing slope
|
| Vegetation Description |
This mature white spruce stand originated in approximately 1780 as a result of wildfire. Picea glauca is the dominant tree but occasional Betula papyrifera and Populus tremuloides persist beneath the spruce canopy. Diameters of the dominant spruce range from 35 to 45 cm, and heights average 25 m with some individuals of 36 m. Spruce tree density in 1993 was 493/ha with a basal area of 32 m2/ha.
Scattered shrubs of Alnus crispa and Viburnum edule make up less than 1% cover. Herbaceous cover is also low and consists primarily of Calamagrostis canadensis, Geocaulon lividum, and Pyrola secunda. The forest floor is covered by a moss mat of Hylocomium splendens.

| History |
This white spruce stand has been the subject of intense studies of white spruce cone and seed production since the mid 1950's. It was a "semi-intensive site during the Black spruce Ecosystem studies in the mid to late 1970's. Permanent vegetation plots were established in 1975 and haver been used as part of the LTER studies. Two studies have been published comparing this stand with an adjacent north slope black spruce stand. A weather station has been maintained periodically at the site during the past 20 years.
