Glacier National Park, British Columbia, Canada - Beaver Valley

 

Large areas in the park are covered by rock, ice, alpine meadows and subalpine parkland. However, the forests in Beaver Valley are classified as ”Inland Rainforest” or ”Columbian Forest”, an interesting mixture of the coastal rainforests and the forests of the Canadian Rockies. On the valley bottom (elevation 950-1100 metres) the forest is composed mainly of four tree species, two of which - Opens internal link in current windowTsuga heterophylla (western hemlock) and Opens internal link in current windowThuja plicata (western redcedar) - are also components of the coastal forests, and the other two - Opens internal link in current windowPicea engelmannii × Opens internal link in current windowglauca (Engelmann × white Spruce) and Opens internal link in current windowAbies lasiocarpa (subalpine fir) - occur in the Rockies. Picea is the tallest tree here. The stoutest is Thuja although it does not become as large here as nearer the coast. Tree species diversity is low and most species are easy to identify.

 

Camping outside the designated areas is permitted beyond 5 km from pavement. The spiny shrub Oplopanax horridus (devil’s club) is abundant, making off-trail hiking rather difficult.
