Silviculture adapted to multiple goals in Swedish small scale forestry

Hörnfeldt, Roland

Abstract

During recent decades a new type of private forest owner has appeared in Sweden, with forestry goals other than simply generating money from wood production; these goals include hunting, maintaining biodiversity, cultural aspects and historical values. However, multiple goals often conflict with each other, leading to a problem of finding practices that can deliver several goals at the same time. Recently, there has been an increasing move to continuous cover forestry and other systems or practices that are considered more likely than clear cutting to fulfil multiple goals. However, an additional problem is that much of what is said about the suitability of different practices is partly based upon beliefs rather than on sound data, so more research is needed in this domain. Finally, identifying stands that are suited to specific practices represents another challenge. The main objective of the research presented in this thesis was to identify tools that can help foresters to select appropriate practices and suitable forest stands that will allow them to achieve the multiple goals of small-scale forest owners. Silvicultural practices were identified through a literature search and their appropriateness and value was determined using matrices summarizing the results of published studies. The results indicated that thinning and successive felling were most suitable for delivering the goals considered. Passive practices were less well adapted. Further literature reviews were undertaken to find criteria relevant to six different situations. In order to determine the link between management practices and results, checklists were created for field-testing. Checklists were also intended to be useful in other situations, and two additional lists, ‘Optimizing natural regeneration of Scots pine (Pinus sylvestris L.)’, and ‘Avoiding false heartwood in ash (Fraxinus excelsior L.)’, were proposed as further examples of useful checklists.
