We examined the fire–climate relationship at the northern limit of commercial forest in western Quebec, a region where forest management is currently competing with fires for mature stands. The main objective was to determine if a particular climate signal would control the fire activity in this region when compared with other parts of the Quebec boreal forest. We used 500-hPa spatial correlation maps to compare the atmospheric patterns associated with the annual area burned (AAB) in the study area, the entire province of Quebec, the intensive (southern Quebec), and the restricted (northern Quebec) fire management zones. Next, dendroclimatic analyses were used to obtain tree-ring estimates of the AAB back to 1904 and to investigate the temporal stability of the fire–climate relationship. The climate controls associated with the AAB of the study area are intermediate between those associated with the AAB of the intensive and restricted fire management zones. The 500-hPa correlation patterns for the 1948–71 and 1972–2001 periods were relatively stable through time for the study area and for the restricted fire management zone. Our results provide a plausible mechanism for explaining the link between sea surface temperature and regional fire activity established in previous studies. They also provide information complementary to the Canadian fire danger rating system that uses daily weather data.

Abstract Since 1955 commercial forest land in east Texas has declined 6 percent while growing stock volume per acre has almost doubled. At the same time, the southern pine beetle population has increased tenfold. It is postulated that increasing numbers of high-density pine stands susceptible to southern pine beetle attack have become available for infestation. This trend will continue for at least 20 to 30 years. At present, the only method available to land managers to reduce the risk of timber loss to the southern pine beetle is to practice intensive forest management.

 O objetivo do presente trabalho foi ajustar, avaliar e selecionar funções de afilamento para a estimativa de diâmetros ao longo do fuste para espécies florestais comercialmente exploradas na Amazônia Mato-grossense. O estudo foi desenvolvido em unidades de manejo florestal, em áreas de Floresta Amazônica, localizadas no município de Santa Carmem, estado do Mato Grosso. Para o ajuste das funções de afilamento, foram cubadas 449 árvores das espécies florestais Goupia glabra, Qualea albiflora, Trattinnickia burseraefolia, Erisma uncinatam e Mezilaurus itauba. Foram ajustados os modelos não segmentados de Schöepfer (1966), Kozak et al. (1969), Hradetzky (1976) e Demaerschalk (1972) adaptado por Moura (1994) e o modelo segmentado de Max e Burkhart (1976). Para avaliar a acuracidade dos ajustes, foi utilizado o coeficiente de determinação ajustado, o erro padrão de estimativa em porcentagem e a análise gráfica dos resíduos, além do valor ponderado dos escores estatísticos e do cálculo das estatísticas auxiliares: desvio, desvio padrão das diferenças, somatório dos quadrados dos resíduos relativos e resíduos percentuais. A função de afilamento de Demaerschalk (1972) adaptada foi a mais acurada para estimar os diâmetros ao longo do fuste de espécies florestais da Amazônia Mato-grossense. Essa função permite descrever a forma dos troncos e possibilita a determinação de sortimentos para múltiplos produtos da madeira.Palavras-chave: Floresta Amazônica; taper; valor ponderado de escores estatísticos. AbstractEvaluation of taper functions for diameter estimated of commercial forest species in amazon matogrossense biome. The aim of this work was to adjust, evaluate and select taper functions for estimating diameters along the stem for commercially exploited species in the Amazon Rainforest in Mato Grosso State. The research was conducted in forest management units in areas of the Amazon Rainforest, located in Santa Carmen, Mato Grosso State. To adjust the taper functions,  449 trees were cubed, of the following species: Goupia glabra, Qualea albiflora, Trattinnickia burseraefolia, Erisma uncinatam and Mezilaurus Itauba. The non-segmented models of Schöepfer (1966), Kozak et al. (1969), Hradetzky (1976), and Demaerschalk (1972), adapted for Moura (1994), and segmented model of Max e Burkhart (1976) were fitted. In order to evaluate the accuracy of adjustments we used the determination coefficient, standard error of estimate in percentage and graphical analysis of the waste, weighted value of statistical scores, and auxiliary statistics: standard deviation, standard deviation of differences, sum of squared residuals and relative percent residue. The function of taper Demaerschalk (1972) was the most accurate to estimate the diameter along the stem for forest species of Amazon Matogrossense. Such function allows to describe the shape of the stem as well as the possibility of determining assortments for multiple products of wood. Keywords: Amazon Rainforest; taper; weighted value of statistical scores.

Commercial Forest

Due to traditional forest management, the primary goal of which is the production of raw wood material, commercial forest stands are characterized by low biodiversity. At the same time, commercial forests make up the majority of forests in the Central European region, which means a significant impact on the biodiversity of the entire large region. Saproxylic species of organisms are a frequently used criterion of biodiversity in forests. Based upon the analysis of 155 scientific works, this paper defines the fundamental attributes of the active management supporting biodiversity as well as the preservation of the production function. Using these attributes, a model management proposal was created for three tree species, which takes into account the results of research carried out in the territory of the University Forest Enterprise of the Czech University of Life Sciences Prague, since 2019. The optimum constant volume of deadwood in commercial stands was set at 40–60 m3/ha, 20% of which should be standing deadwood. The time framework is scheduled for an average rotation period of the model tree species, while the location of deadwood and frequency of enrichment must comply with the rate of decomposition, the requirement for the bulkiest dimensions of deadwood possible, and the planned time of tending and regeneration operations in accordance with the models used in the Czech Republic. The goal of active management is to maintain the continuity of suitable habitats for sensitive and endangered species. The estimates of the value of retained wood for decomposition can be as high as 45–70 EUR/ha/year for spruce and beech, and about 30 EUR /ha/year for oak.
