The three-toed woodpecker (Picoides tridactylus)was first observed in the region of Pays-d'Enhaut ten years ago and is a great specialist of dead wood. This species is a suitable indicator for the quantitative and qualitative evaluation of ecological forest quality. The investigation results originating from five spruce mountain forests where the bird is present and three forests where it is assert are inventoried in the Pays-d'Enhaut region of Switzerland. The results suggest that the emergence of the woodpecker population could be due to under-management of the forest over the last forty years. The dead wood volumes in the forest with the woodpecker are similar to those of other unmanaged European forests. Forests situated above 1400 m above sea-level are recommended to be considered as ‹forest reserves›, whereas in managed forests up to an altitude of 1400 m, all trees with woodpecker's beakmarks and all snags with DBH over 30 cm should be left.

Natural forest reserves: selection criteria, where and what for? (Essay) The question “How large should the total extent of strict natural forest reserves be?” dominates the current debate about the need of unmanaged forests for biodiversity conservation in Central Europe. However, within a system of close-to-nature forest management, the quality, location, composition and distribution of natural forest reserves might have higher impacts on the diversity of species, communities and natural processes than the reserves' extent alone. Strictly speaking, the correct answer about the minimal required surface is directly related to the superior conservation objectives. In addition, the required ratio of forest reserves in relation to the total forest area is influenced by other factors such as the abundance and distribution of forests pirmarily managed for conservation objective, protected forest biotopes and old-growth stands as well as the general standards for an integrative, close-to-nature silviculture. Since concrete, superior objectives for forest biodiversity conservation are still missing in Central Europe, we put the focus of this article on the criteria that influence the conservation-specific impact and quality of strict natural forest reserves. These are amongst others the extent and compactness of a reserve, its habitat continuity and connectivity, the representativeness of forest types, their species composition and biogeographic distribution, a reserve's site heterogeneity and naturalness of its vegetation as well as the abundance of key structures and target species.

AbstractThe protected area network of Africa has grown from nothing to over 2 million km2 in the past 110 years. This network covers parts of all biomes and priority areas for biodiversity conservation but protected area gaps remain, as identified at the 5th World Parks Congress in 2003. Forest reserves, managed by Forest Departments, are typically excluded from global protected area lists, but in Africa they are found in 23 countries and cover at least 549,788 km2, adding 25% to the conservation estate. Forest reserves protect 5.3% (2,027 km2) of the dry forest habitats, 5% (165,285 km2) of lowland and montane moist forests, 2.6% (364,354 km2) of savannah woodlands, 1.8% (10,561 km2) of flooded grasslands, and 1.65% (1,177 km2) of mangroves. Forest reserves also protect parts of three conservation schemes: 6.5% (61,630 km2) of BirdLife's Endemic Bird Areas, 3.4% (147,718 km2) of Conservation International's Hotpots and 3.4% (346,864 km2) of WWF's Global 200 Ecoregions. Several of the global protected area gaps identified in Africa are also covered by forest reserves, in the Eastern Arc Mountains, Eastern African coastal forests, Kenyan Highlands, Cameroon-Nigerian Mountains, West African Forests and mountain areas of Malawi, Zimbabwe, Mozambique and Zambia. Some African forest reserves have a legally defined role in biodiversity conservation and are strictly protected; they thus fit criteria for protected areas. Working with forest departments in individual countries may help develop a more comprehensive protected area network without creating additional new reserves.

Reducing emission from deforestation and forest degradation (REDD+) programme has prime concern to carbon stock enhancement rather than biodiversity conservation. Participatory managed forest has been preparing to get benefit under this programme, and collaborative forest is one of them in Nepal. Hence, this research is intended to assess the relationship between carbon stock and biodiversity. Three collaborative forests (CFMs) were selected as study sites in Mahottari district, Nepal. Altogether 96 sample plots were established applying stratified random sampling. The plot size for tree was 20 m × 25 m. Similarly, other concentric plots were established. Diameter at breast height (DBH) and height were measured, species were counted, and soil samples were collected from 0–0.1, 0.1–0.3, and 0.3–0.6 m depths. The biomass was calculated using equation of Chave et al. and converted into carbon, soil carbon was analyzed in laboratory, and plant biodiversity was calculated. Then, relation between carbon stock and biodiversity was developed. Estimated carbon stocks were 197.10, 222.58, and 274.66 ton ha−1 in Banke-Maraha, Tuteshwarnath, and Gadhanta-Bardibas CFMs, respectively. The values of Shannon-Wiener Biodiversity Index ranged 2.21–2.33. Any significant relationship between carbon stock and biodiversity, and was not found hence REDD+ programme should emphasize on biodiversity conservation.

Unlike the numerous works concerning the effect of management on the forest mycobiome, only a few studies have addressed how fungi from different trophic groups recover from natural and anthropogenic disturbances and develop structural features typical of unmanaged old-growth forests. Our objective is to compare the soil fungal assemblages represented by different functional/trophic groups in protected and managed stands located in European mixed forests dominated by Scots pine. Fungal communities were analyzed using high-throughput Illumina MiSeq sequencing of fungal internal transcribed spacer 1 (ITS1) amplicons. Formerly managed forest reserves (established around 50 years ago) and forests under standard forest management appeared to be similar in terms of total and mean species richness of all fungal operational taxonomic units (OTUs), as well as OTUs assigned to different functional trophic groups. Among the 599 recorded OTUs, 497 (83%) were shared between both management types, whereas 9.5% of taxa were unique to forest reserves and 7.5% were unique to managed stands. Ascomycota and Basidiomycota were the predominant phyla, comprising 88% of all identified fungi. The main functional components of soil fungal assemblages consisted of saprotrophic (42% fungal OTUs; 27% reads) and ectomycorrhizal fungi (16%; 47%). Two-way analysis of similarities (ANOSIM) revealed that both site and management strategy influenced the species composition of soil fungal communities, with site being a primary effect for saprotrophic and ectomycorrhizal fungi. Volume of coarse and very fine woody debris and soil pH significantly influenced the ectomycorrhizal fungal community, whereas saprotrophic fungi were influenced primarily by volume of coarse woody debris and soil nitrate concentration. Among the identified fungal OTUs, 18 red-listed fungal species were identified from both forest reserves and managed forests, comprising two ECM fungi and four saprotrophs from the category of endangered species. Our results suggest that the transformation of fungal diversity after cessation of forest management is rather slow, and that both forest reserves and managed forests help uphold fungal diversity.
