Certificação florestal no Brasil: uma ferramenta eficaz para a conservação das florestas naturais?

A certificação florestal é descrita como instrumento de mercado para apoiar um manejo florestal sustentável. Um foco especial é dado pela certificação sob FSC, mas também pelo sistema esquema nacional de certificação florestal no Brasil, o CERFLOR. O que se questiona é se a certificação poderá contribuir com a adoção de práticas de bom manejo pela motivação devido às vantagens advindas da certificação ou pela conscientização do consumidor. As principais forças motrizes do desmatamento nas florestas brasileiras ainda existem, por isso a contribuição da certificação para a conservação das florestas naturais parece ser limitada.

Borboletas (Lepidoptera: Hesperioidea e papilionoidea) de val de serra, região central do rio grande do sul, Brasil

The butterfly fauna of the Atlantic Forest Biome is reasonably well-known up to the southern limit of its distribution. However, there are knowledge gaps nearby the central region of Rio Grande do Sul State, whose forest areas are considered priorities for biological conservation. This study investigated the butterfly assemblage of a riparian fragment in an ecotone area between Mixed Ombrophilous Forest and Seasonal Decidous Forest, in Itaara municipality. From September 2005 to September 2006, after 105 net-hours through active search sampling, 877 butterflies were registered representing 104 species. Three more species were registered posteriorly, increasing total richness to 107. The most abundant species were the Nymphalidae Hermeuptychia hermes (Fabricius, 1775), Yphthimoides celmis (Godart, [1824]), Agraulis vanillae maculosa (Stichel, [1908]), Tegosa claudina (Eschscholtz, 1821) and Vanessa braziliensis (Moore, 1883). One new record for the State and four new ones for the central region were registered besides the southern endemic Papilionidae Euryades corethrus (Boisduval, 1836) and the Lycaenidae Arcas ducalis (Westwood, 1852), considered indicator of Atlantic forest preserved areas. Due to the representativeness of the registered fauna, it is suggested the increase of conservation efforts in the area and stimulation of new ecological studies with the local biodiversity

Suitability of close-to-nature silviculture for adapting temperate European forests to climate change

In many parts of Europe, close-to-nature silviculture (CNS) has been widely advocated as being the best approach for managing forests to cope with future climate change. In this review, we identify and evaluate six principles for enhancing the adaptive capacity of European temperate forests in a changing climate: (1) increase tree species richness, (2) increase structural diversity, (3) maintain and increase genetic variation within tree species, (4) increase resistance of individual trees to biotic and abiotic stress, (5) replace high-risk stands and (6) keep average growing stocks low. We use these principles to examine how three CNS systems (single-tree selection, group selection and shelterwood) serve adaptation strategies. Many attributes of CNS can increase the adaptive capacity of European temperate forests to a changing climate. CNS promotes structural diversity and tree resistance to stressors, and growing stocks can be kept at low levels. However, some deficiencies exist in relation to the adaptation principles of increasing tree species richness, maintaining and increasing genetic variation, and replacing high-risk stands. To address these shortcomings, CNS should make increased use of a range of regeneration methods, in order to promote light-demanding tree species, non-native species and non-local provenances

Adaptive measures: integrating adaptive forest management and forest landscape restoration

Key message Adaptive Forest Management and Forest Landscape Restoration do not contradict \u2013 ecosystemintegrityand health are benefits and central goals in both concepts, and thus can beintegrated. The Adaptive Measures concept can be helpful in streamlining and focusing existingconcepts on forest adaptation and restoration as well as to help forest restoration to focusmore on the ability of ecosystems to selforganize in the future and to adapt to changingenvironmental conditions instead of attempting to restore to a previous historical state.There is an urgent need to consider novel or no-analogue ecosystems to potentially providethe best mix of ecosystem services in the future under uncertaint
