Browse And Herbage Yield Following Clearing In The Alberta Montane Aspen Ecoregion, Edmund S. Telfer
Aspen Bibliography
Small openings were cleared by bulldozing in montane aspen Populus tremuloides forest in southwestern Alberta in 1976. Production of browse, forbs and grasses was measured at the end of the growing season 2 and 7 years later. In the 2nd year production of woody twigs was significantly higher than on uncut controls (87.0 kg/ha compared to 56.0 kg/ha). In the 7th year twig production on cut blocks still exceeded that on the control blocks (53.9 kg/ha compared to 35.5 g/ha). Leaf production was also significantly higher on the treated blocks during both years. Forb production and species composition was not …

Moose (Alces Alces L.) Browsing In Young Scots Pine Stands In Relation To The Characteristics Of Their Winter Habitats, Risto Heikkila, Sauli Harkonen
Aspen Bibliography
Moose (Alces alces L.) browsing was studied in young Scots pine (Pinus sylvestris L.) stands mixed with deciduous trees in high-density winter ranges. The proportional use of twig biomass decreased as the availability increased. The total as well as proportional biomass consumption were higher on the moist than on the dry type of forest. The per tree consumption of pine was higher on the moist type, where the availability of pine was lower. Deciduous trees were more consumed on the moist type, where their availability was relatively high. The consumption of pine saplings increased as the availability of …
