Disturbance and succession have long been of interest in ecology, but how landscape patterns of ecosystem structure and function evolve following large disturbances is poorly understood. After nearly 25 years, lodgepole pine (Pinus contorta var. latifolia) forests that regenerated after the 1988 Yellowstone Fires (Wyoming, USA) offer a prime opportunity to track the fate of disturbance-created ...

ISSN 1652-6880, ISBN 91-576-7055-2 This thesis includes five papers from four studies on lichen diversity in its broad sense. The overall objectives were to examine species richness, composition, distribution, an...

In Finland, the forest resource data for management planning is traditionally collected by periodic standwise field inventories, which are usually carried-out over different regions during 10–15 year intervals. The data is used for the compilation of management plans for forest estates. Between inventories the plan and the original stand data can be used, e.g., in the operational planning of ti...

• Novel stand-level biomass models developed for 9 shrubland types, by groups and all together. Nonlinear iterative seemingly unrelated regression used to fit systems of integrated additive equations. Models were also standing fuel loads size condition, litter. Predictor variables stand height alone or with cover litter depth. Generally, performed reasonably well even those based on alone. Shru...

selection cutting using skidding system often causes physical damage to residual stand through felling and skidding resulting decline of bole quality and tree value. this research evaluated logging damage using skidding system on residual trees and stand regeneration in uneven aged hardwood forest of asalem, were selection cutting was practiced. in this regard, systematic sampling method was us...
