Historical forest landscape dynamics include consideration of spatial and temporal distributions of forest conditions over recent history and also historical disturbance regimes. Understanding of historical landscape dynamics in these senses is relevant to planning future management of federal forest lands on both policy and ecological grounds. Although some particular elements of our policy fr...

The current growing body of evidence for diversity-disturbance relationships suggests that the peaked pattern predicted by the intermediate disturbance hypothesis (IDH) may not be the rule. Even if ecologists could quantify the diversity-disturbance relationship consistent with the IDH, the applicability of the IDH to land management has rarely been addressed. We examined two hypotheses related...

Dependency analyses have become crucial in today’s enterprise architecture practices, which usually face complex IT landscapes with highly interdependent applications. In such environments, a deep understanding of the application’s context is essential to determine its qualities and project its further evolution. However, method support for making this context a tangible IT landscape management...

The effects of different combinations of multiple, variable-intensity silvicultural treatments on fire and habitat management objectives were evaluated for a ±6,000 ha forest reserve using simulation models and optimization techniques. Our methods help identify areas within the reserve where opportunities exist to minimize conflict between the dual landscape objectives. Results suggest that mos...

The overall aim of this dissertation was to study the public’s preferences for forest regeneration fellings and field afforestations, as well as to find out the relations of these preferences to landscape management instructions, to ecological healthiness, and to the contemporary theories for predicting landscape preferences. This dissertation includes four case studies in Finland, each based o...
