“…For biodiversity conservation in the management of Natura 2000 forest areas, it is fundamental to know the resilience of each habitat type and the fragility of the vegetation (Velázquez et al 2010). This means that it is important to know the rate at which the habitat recovers to its initial status after a perturbation occurs.…”

In Slovenia, the Natura 2000 network covers more than 37% of the country. Forests dominate more than 70% of this area, and forest management is a significant driver of diversity. Depending on the options applied, forest management may enhance or decrease forest biodiversity. Dinaric fir-beech forests (part of Natura 2000 habitat type) with remarkable nature-conservation interest and timber production functions were selected for this study. With the aim of testing the effects of different silvicultural measures on plant diversity in these forests, and consequently on biodiversity in a broader sense, three sites in the Slovenian part of a Dinaric fir-beech forest range were studied. The plant species diversity was assessed before and after the implementation of silvicultural measures of three intensities: (1) control plots -no logging; (2) logging of 50% of the growing stock; and (3) logging of 100% of the growing stock. Before the implementation of the silvicultural measures, the mean number of plant species per 400 m² vegetation plots was 48.8, and the mean value of the Shannon's diversity index was 2.41. Two years after the measures were implemented, different magnitudes of plant species turnover were observed. There were no significant changes in plant diversity status and vegetation composition in the control plots. Two years after 50% of the growing stock was logged, the mean number of species was 73.3, and the mean value of the Shannon index was 3.21. In the plots where all the trees were removed, the mean number of species was 87.4, and the mean value of the Shannon index was 3.42. In parallel with the increases in the diversity parameters, the cover of the herbaceous layer increased significantly with an increase in the silvicultural intensity, indicating that short-term species turnover can mostly be attributed to herbaceous plant species. As a result of changed stand and ecological conditions, an increased plant diversity, a greater biodiversity in a broader sense and an improved habitat suitability for different animal species could be expected.

“…Gradients between or at the edge of community clusters are likely to represent patterns of processes that determine habitat structure. Such multidimensional transition areas are of utmost importance in ecosystem management as required in the Natura 2000 network, where gradual differences in habitat conditions determine the required management actions [25]. In contrast to a pre-definition of discrete habitat units, n-dimensional representation of species-environmental interrelations can be described quantitatively using ordination techniques [26].…”

Abstract:The monitoring of ecosystems alterations has become a crucial task in order to develop valuable habitats for rare and threatened species. The information extracted from hyperspectral remote sensing data enables the generation of highly spatially resolved analyses of such species' habitats. In our study we combine information from a species ordination with hyperspectral reflectance signatures to predict occurrence probabilities for Natura 2000 habitat types and their conservation status. We examine how accurate habitat types and habitat threat, expressed by pressure indicators, can be described in an ordination space using spatial correlation functions from the geostatistic approach. We modeled habitat quality assessment parameters using floristic gradients derived by non-metric multidimensional scaling on the basis of 58 field plots. In the resulting ordination space, the variance structure of habitat types and pressure indicators could be explained by 69% up to 95% with fitted variogram models with a correlation to terrestrial mapping of >0.8. OPEN ACCESSRemote Sens. 2015, 7 2872Models could be used to predict habitat type probability, habitat transition, and pressure indicators continuously over the whole ordination space. Finally, partial least squares regression (PLSR) was used to relate spectral information from AISA DUAL imagery to floristic pattern and related habitat quality. In general, spectral transferability is supported by strong correlation to ordination axes scores (R 2 = 0.79-0.85), whereas second axis of dry heaths (R 2 = 0.13) and first axis for pioneer grasslands (R 2 = 0.49) are more difficult to describe.

“…The main threat to the areas in the Natura Network 2000 in Spain is forest fires (Velázquez et al, 2010) due to the lack of connection between biodiversity conservation and management based on objectives centered on economic activities (Hoyos et al, 2012). Some parts of the study area were declared protected areas in 2004, without a participation process or an explanation of the consequences for the local population.…”

Aim of study: To develop a methodology to obtain knowledge in public participation processes.Area of study: Fonsagrada-Os Ancares (Spain), region located in the northern Iberian Peninsula.Material and methods: This study proposes a new method for generating questionnaire survey in participative forest plan with four stages. The validation of this method is performed in the context of a tactical sub-regional forest plan.Main results: The questionnaires based on criteria and indicators proved to be effective in obtaining key information for planning. The method used offers tools to reach the consensus on natural resource management, through the knowledge gained by selecting relevant information (preferences, opinions, and expectations) from past, present, and future forest activity, focusing on solutions to conflicts.Research highlights: The use of appropriate indicators and criteria in the planning phase allows for obtaining knowledge concerning the preferences and future challenges for forest management.
