Book excerpt: Scots pine (Pinus sylvestris L.) is the most widely distributed conifer in the world and, presently, the second most important commercial tree species in Sweden after Norway spruce (Picea Abies L.). However, the share of Scots pine in regenerations in southern Sweden has decreased alarmingly during the last twenty years, yielding space to Norway spruce. Recent surveys have shown that Scots pine is rarely the species of future crop trees in young stands. Forest ownersu2019 perception of the uncertainty of Scots pine regeneration outcomes has been identified as one of the main factors causing this trend. Conventional regeneration methods for Scot Pine in southern Sweden are planting, direct seeding and natural regeneration with seed trees or under shelterwood. There is still a lack of knowledge about the long term effects of the regeneration method on growth and economy of Scots pine stands in the region. In present study long term development of Scots pine stands is simulated starting from short term regeneration outcomes observed in actual field experiments. Economy of the stand management is analysed in terms of cash-flow and Land Expectation Value (LEV), volume growth in terms of mean annual increment (MAI) for whole rotation. Effects of different discount rates and regeneration costs on the LEV outcomes are tested.

This book was released on 1997 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the changes in the spatial distribution of lodgepole pine stands as regeneration proceeds. Data were collected from 29 plots established in regenerating lodgepole pine stands and remeasured two years later. Nine of these plots had sufficient ingrowth to warrant an analysis of their spatial distribution dynamics. Ripley's K(t) statistic was used to identify the spatial pattern of the trees at the initial measurement, the ingrowth trees, and the combined initial and ingrowth trees. The K(t) statistic was also employed to detect correlation between the locations of the initial and the ingrowth trees. The spatial patterns were modelled by a Poisson cluster process, a Poisson process, or a Markov point process when the trees were aggregated, random, or regularly distributed, respectively.
