The use of water buffalos for landscape maintenance started ten years ago in Germany. Now, more than 2,100 buffalos are kept by about 90 breeders, and first results concerning their usefulness for landscape management are available. Buffalos are mainly used on particularly wet sites which cannot be grazed by cattle or other domestic animals. Although grazing of wetlands, river banks and water bodies is still controversial, early results from literature and our own research clearly indicate the beneficial impact of moderate grazing on such sites for birds, amphibians, vegetation and insects. This paper presents a short literature review and the first results of the BUBALUS project at Brandenburg University of Technology (BTU) and general experience from other projects. Source

Effectiveness of Protection Areas for the Conservation of Rare and Endangered Vascular Plant Species - Investigation in the Lowlands of Lower Saxony, Germany The establishment of protected areas is a central tool in species conservation. Using the 41 geographical regions of the lowlands of Lower Saxony as a model region, the study introduces a method to test the effectiveness of nature protection areas and Natura 2000 sites for the conservation of rare and endangered vascular plant species (RL, Red List species). The results show that RL species are effectively protected by nature protection areas in 85% of the geographical regions; for RL species depending on forest habitats this is the case in only 61% of the geographical regions. The extension of the protection area system to include Natura 2000 sites considerably improves the situation. The approach allows the identification of regions with high species richness of endangered plants (hotspots) that should be particularly considered for conservation and management actions. Source

The German National Natural Heritage scheme comprises ca. 125,000 ha of outstanding protected areas in natural and semi-natural environments. Approximately 60,000 ha of this land will be transferred to the private ownership of the German Federal Foundation for the Environment (DBU). A monitoring system is currently being developed in order to have a means of tracking the effectiveness of nature conservation measures on DBU Natural Heritage sites. Based on conservation goals for each site (including predefined standards and norms), the monitoring concept will include nine modules. The modules are categorised in terms of major conservation strategies (conservation of man-made habitats, maintenance of natural processes), vegetation classification (forest, open habitats, transition habitats) and scale of observation (entire area of all natural heritage sites, representative sampling areas, and data counting areas). These modules can be applied on a national, regional or local scale. An integrative approach is applied to develop meaningful and comprehensive indicators by pre-screening existing indicator sets. Thanks to the modular concept, this monitoring approach will be transferable to further National Natural Heritage sites. Source

Biomass equations are a helpful tool to estimate the tree and stand biomass production and standing stock. Such estimations are of great interest for science but also of great importance for global reports on the carbon cycle and the global climate system. Even though there are various collections and generic meta-analyses available with biomass equations for mature trees, reports on biomass equations for juvenile trees (seedlings and saplings) are mainly missing. Against the background of an increasing amount of reforestation and afforestation projects and forests in young successional stages, such equations are required. In this study we have collected data from various studies on the aboveground woody biomass of 19 common tree species growing in Europe. The aim of this paper was to calculate species-specific biomass equations for the aboveground woody biomass of single trees in dependence of root-collar-diameter (RCD), height (H) and the combination of the two (RCD2 H). Next to calculating species-specific biomass equations for the species available in the dataset, we also calculated generic biomass equations for all broadleaved species and all conifer species. The biomass equations should be a contribution to the pool of published biomass equations, whereas the novelty is here that the equations were exclusively derived for young trees. © 2016 Springer-Verlag Berlin Heidelberg Source
