The mountain ecotype of the woodland caribou (Rangifer tarandus caribou) is highly dependent on the arboreal hair lichens Bryoria spp. and Alectoria sarmentosa during winter. In parts of British Columbia, partial-cutting silvicultural systems have been us... see more

Habitat management for woodland caribou (Rangifer tarandus caribou) in southeastern British Columbia has generally focussed on protecting old-growth forests from logging. As that strategy becomes more difficult to maintain, biologists are beginning to exp... see more

The study was carried out in Kuusamo (66°15'N, 29°05'E) and Inari (68°30'N, 28°15'E), northern Finland, where 24 and 22 Scots pine stands were studied respectively. Clear-cutting (logging residue) caused a decline in lichen biomass for some few years, but... see more

Rapid climate change is predicted for British Columbia’s Inland Temperate Rainforest (ITR), a globally unique ecosystem. Lichens, which may serve as effective biomonitors of ecosystem health, have been proposed for use as climate change indicators for a v... see more

Epiphytic lichen thalli on trees may protect arthropods - herbivores or their natural enemies. Although the relationships between lichens on the forest floor to arthropods have been widely studied in boreal regions, those between epiphytic lichens and the... see more

The chemical composition and nutritive value of different forage plants and commercial feeds of reindeer were studied by standard methods in the Finnish reindeer herding area during 1980-86. The nutritive values, particularly the protein and mineral conte... see more

Woodland caribou (Rangifer tarandus caribou) in southeastern British Columbia feed mainly on arboreal lichens in winter. Some modified forestry practices that have been used or proposed for caribou ranges are reviewed. Partial cutting results in the reten... see more

Reindeer husbandry and forestry are practised in Finland in the same areas and practisers of these sources of livelihood not been able to avoid conflicts. Large clear-cutting and ploughed areas especially have diminshed the reindeer's winter ranges. In wi... see more

In the 1970s, mean lichen biomass ranged by the earmark districts (comprising of 2-9 adjacent herding associations) between 54 kg and 380 kg DM per ha correlating negatively with animal density per lichen ranges (range 1.5 - 14.3 ind. per km2). Biomasses ... see more
