The paper presents the results of assessing the phytocenotic and sozological significance of the beech forests of Dagestan, which have been preserved in the study area since the tertiary period in a depleted and transformed form. Occupying a fairly large area, they perform functions that maintain balance in the ecoregion of the Eastern Caucasus. In addition, the beech forests of Dagestan are rich in hyrkanian and colchian relict and endemic elements, rare protected species. Based on the geobotanical description of seventy-three trial plots in various physical and geographical areas of Dagestan using the ecological and phytocenotic method, nineteen associations were identified, to identify the environmental value of which a system of criteria for determining the environmental significance of associations was applied. It was revealed that the greatest conservation value (P4) is represented by associations growing in the lowland and foothill parts: Fagetum taxosoilexosum (area less than 1 ha), Fagetum qercoso-euphorbosum, represented by insignificant in derivatives of hyrkan forests and Fagetum taxoso-varioherbosum, extremely rare throughout the interrupted strip of beech forests of foothill Dagestan. Such associations of foothill beech forests as Fagetum nudum, Fagetum compositum loniceroso-varioherbosum, Fagetum sambucoso-efemeroso-filicosum, and Fagetum efemer-oso-varioherbosum, which also occupy relatively small areas, have a high conservation value (P3). The associations Fagetum compositum fruticoso-varioherbosum, Fagetum compositum carpinoso-varioherbosum, Fagetum filicosum, Fagetum festucosum, and Fagetum rubosum are classified as communities with an average conservation value of P2. All associations of beech forests of the foot-hills of Dagestan are subject to reduction of areas under the influence of high anthropogenic load: logging, cattle grazing, economic development of the territory. In subalpine beech forests, the asso-ciations Fagetum filicoso-varioherbosum and Fagetum myrtilloso-varioherbosum — P3 are of high conservation value. Communities with average values of conservation value (P2) include the following associations: Fagetum fruticoso-filicoso-varioherbosum, Fagetum compositum varioherbosum, Fagetum compositum filicoso-varioherbosum. Associations Fagetum festucosa-varioherbosum, Fagetum compositum festucoso-vatioherbosum are classified as communities with low conservation value-P1. In this area, there is no reduction in areas due to the inaccessibility of forest areas for timber harvesting.

Estimation of changes in the microclimatic parameters of beech forests of the Stilsky Hillside, by measuring the water-temperature indicators of the soil regime and bryoindication, were performed. Fragmentation of forest causes significant changes in microclimatic parameters in bondary habitats areas, which leads to both biodiversity loss and a decrease of the unchanged forest areas. In fragmented beech forests, the influence of the edge effect on the water-temperature regime of soils is observed within a distance of 20-40 meters, but the eco-floristic structure of nemoral moss vegetation is stabilized only at a distance from 160 m. Thus, bryobiontes are a shown to be a sensitive marker of the microclimatic regime changes in a fragmented ecosystem. In the studied beeches Metzgeria furcata, Radula complanata, Anomodon attenuatus, A. viticulosus, Cirriphyllum crassinervium are indicators of the "interior forest". The determined amplitude of the edge effect indicates the fragmentation as a crucial factor on the small areas of forest and its role in the loss of climate-sensitive groups of biota, primarily mosses.

Forest Stewardship

The concept of "High Conservation Value" which was initially used by the Forest Stewardship Council, now plays an increasingly important role in several areas, and most significantly in the design and implementation of development projects. Within the framework of certification of community forests in Cameroon, this concept has been implemented in close collaboration with interested communities. Based on the activities conducted, it is worth noting that the consideration of informal management methods appear to result in better protection of biodiversity. Several categories of High Conservation Values were identified in 2 community-managed forests (Coopérative des Paysans de la Lékié & Bimbia Bonadikombo Community Forests) in Cameroon. Rare or endangered ecosystems, more than 300 plant species and more than 20 wildlife species, including endemic, rare, threatened or endangered species were found. Traditional conservation methods based on culture, as well as some ancestral practices and beliefs help to achieve this protection. Decision-makers and academics should learn from this empirical knowledge for protection programmes and projects of biodiversity.

AbstractWetlands have recently become of high environmental interest. The restoration effects on habitats like fens are one of the main topics of recent restoration ecology, especially due to their interconnection with other ecosystems. We studied the manual mowing effect on abandoned fen using the response of three study taxa: diurnal butterflies, flower-visiting beetles and vascular plants. Our results showed that butterflies seems to be quickly-responding indicator taxon for evaluation and that restored management had a positive effect on both species richness and composition of this insect group. The results indicated that the manual mowing effect could be rapid. In comparison with the surrounding landscape, we found that: (i) the manually mowed site was most similar to strictly protected area, (ii) some species of high conservation value could reach higher abundance in restored than protected site, and (iii) manual mowing could bring a new type of habitat (i.e., spatial heterogeneity) compared to the other management types (abandonment, conservation and agri-environmental mowing). The main implication seems to be optimistic for practice: The manual mowing of long-term abandoned fen is leading to the creation of habitat with high conservation value in a relatively short time.

Within the Project “Animal Biodiversity Monitoring in the Alpine Environment” the Orthoptera fauna has been studied in a three-year period (2013-2015). The first check-list of the protected area, with ecological and biogeographical notes, is presented. We found 40 species (16 Ensifera, 24 Caelifera), corresponding to 11% of the Italian Orthoptera fauna. A geographic differentiation in species distribution among the three areas (Alto Adige - BZ, Trentino - TN and Lombardy - BS and SO) has been detected. The genus Barbitistes is represented by B. serricauda in Alto Adige and B. alpinus in Trentino and Lombardy. Kisella irena is restricted to Peio and Rabbi Valleys only, in connection with this species distribution in Trentino. Within the Park, Euthystira brachyptera is distributed only in Lombardy, despite its habitat is apparently extensively available also in Trentino and Alto Adige. We found Omocestus haemorrhoidalis and Chorthippus vagans only in Val Venosta (BZ). Only two species, previously reported for the study area, has not been detected during our surveys: Celes variabilis and Ruspolia nitidula. The first site of presence of Tettigonia caudata, rare in Italy, within the Park boundaries has been discovered near Martello (BZ). Two endangered taxa of high conservation value, Epacromius tergestinus ponticus and Crysochraon dispar, reported in the last Century just outside the Park boundaries, are probably extinct today due to habitat loss.

High Conservation Value Forest (HCVF) is the identification of High Conservation Values that are important and need to be protected. Under FSC certification mechanism, HCVF becomes one of Principles and Criteria to attain certification. In this study, we identify the existence of HCVF in Perum Perhutani KPH Kendal to support implementation process of FSC certification. Qualitative method was conducted through observation and secondary data from Perum Perhutani KPH Kendal. Data analysis showed through ecolabel certification, Perum Perhutani KPH Kendal has been identified HCVF area covering 2,715.5 hectares consists of HCV 1 until 6. Secondary Natural Forest (HAS) Subah and Kaliwungu for Ulolanang and Pagerwunung Nature Reserve buffer zone include as HCV 1.1, conservation area of leopard (Panthera pardus melas) and Pangolin (Manis javanica).for HCV 1.2, conservation area of lutung (Trachypiyhecus auratus) as endemic species for CITES App I and Critically Endangered species include as HCV 1.3, Goa kiskendo for bats species habitat include as HCV 1.4, regions of interest species for Deer (Cervus timorensis) and Kepodang (Oriolus chinensis) as HCV 2.3, Germplasm Protection Region/ KPPN area with high biodiversity include as HCV 3, river border area and water springs for HCV 4. While, utilization of firewood, grass for cattle fodder include as HCV 5 and 14 cultural sites include as HCV 6. From monitoring and evaluation of HCVF data, showed that in 2011-2015 the level of diversity for flora and fauna were increased.
