Anticosti Island

The knowledge of natural disturbance dynamics and preindustrial landscapes is essential to implement sustainable forest management. Recent findings identify the lack of a forest dynamics model, different from the standard cyclic model of Baskerville (1975. For. Chron. 51: 138–140), for balsam fir ( Abies balsamea (L.) Mill.) ecosystems of maritime eastern Canada. With the use of historical forest maps and dendrochronology, we reconstructed the range of variability of the preindustrial landscape (6798 km2) and inferred on the natural disturbance dynamics of the balsam fir forest of Anticosti Island. The preindustrial landscape was characterized by a forest matrix of overmature softwood stands with inclusions of younger softwood stands ranging from 0.1 to 7837 ha in size. Widespread stand-initiating events were apparently rare in the preindustrial landscape over the last 160 years. Since our results were not well represented by the cyclic model, which predicts the occurrence of a mosaic of stands in different age classes, we proposed an alternative forest dynamics model for eastern balsam fir ecosystems near the Gulf of St. Lawrence. Forest management inspired by this alternative model may be more appropriate to maintain or restore ecological characteristics of balsam fir forests of this region within their range of natural variability.

Landscape Models

Forest management practices conducted primarily at the stand scale result in simplified forests with regeneration problems and low structural and biological diversity. Landscape models have been used to help design management strategies to address these problems. However, there remains a great deal of uncertainty that the actual management practices result in the desired sustainable landscape structure. To investigate our ability to meet sustainable forest management goals across scales, we assessed how two models of forest dynamics, a scaled-up individual-tree model and a landscape model, simulate forest dynamics under three types of harvesting regimes: clearcut, gap, and uniform thinning. Althougth 50–100 year forecasts predicted average successional patterns that differed by less than 20% between models, understory dynamics of the landscape model were simplified relative to the scaled-up tree model, whereas successional patterns of the scaled-up tree model deviated from empirical studies on the driest and wettest landtypes. The scale dependencies of both models revealed important weaknesses when the models were used alone; however, when used together, they could provide a heuristic method that could improve our ability to design sustainable forest management practices.

Dynamics of Lecythidaceae species were evaluated 13 years after logging in a dense tropical rain forest located in the municipality of Moju, Pará (02º 08’ 14’’ and 02º 12’ 26” S; 48º 47’ 34”S and 48º 48’ 14” W - SAD 69). Two hundred ha out of a 1,050 ha forest area were selectively logged for timber (23 m3 ha-1 harvested from 25 species) in 1997. Twenty-two permanent sample plots of 0.5 ha (11 ha sample area) were established and all trees with DBH ≥ 10 cm were measured and identified in 1995, 1998 and 2010. Density (trees ha-1) and basal area (m2 ha-1) of the species were evaluated in the three occasions. The opening of canopy caused by logging reduced the density and basal area of five species, but produced a positive response in nine species, boosting their natural regeneration and allowing the ingrowth of one species that was not present in the studied area in the beginning.Keywords: Forest dynamics; Tauari; forest management; Amazon Forest. ResumoEfeito da exploração de madeiras na densidade e área basal de espécies de Lecythidaceae no leste da Amazônia. Analisou-se a dinâmica de espécies de Lecythidaceae 13 anos após a exploração madeireira, em uma Floresta Ombrófila Densa no município de Moju, Pará (02º 08’ 14’’ e 02º 12’ 26” S; 48º 47’ 34”S e 48º 48’ 14” W - SAD 69). De uma área de floresta de 1.050 ha, foram selecionados 200 ha para exploração seletiva, em 1997, de 25 espécies comerciais madeireiras (intensidade de 23 m3 ha-1). Foram alocadas 22 parcelas permanentes de 0,5 ha, totalizando 11 ha amostrais, onde foram medidas todas as árvores com DAP≥ 10 cm, nos anos de 1995, 1998 e 2010. Analisou-se a densidade (árvores ha-1) e área basal (m2 ha-1) das espécies, nas três ocasiões. A abertura do dossel causada pela exploração reduziu a densidade e a área basal de cinco espécies, porém produziu impacto positivo em nove espécies, estimulando a sua regeneração natural e, inclusive, proporcionando o ingresso de uma espécie que não estava presente na área monitoradaPalavras-chave: Dinâmica da floresta; Tauarí; manejo florestal; Floresta Amazônica.
