Species protection in settlements between legal and technical demands and conflicting practice
Summary
Although human demands on form and function are the primary objectives regarding buildings, animal species protection also has its entitlement and specific requirements in settlements. Those must be addressed in planning and implementation procedures, even in the case of single building refurbishments, not least because of existing legal regulations. Biodiversity decline does not stop at the boundaries of settlements, which in addition are expanding at the expense of the surrounding landscape. Qualities and quantities of structures and functional interconnections necessary for species protection have to be ensured. The amount of useable habitats for bats and birds is directly connected with the structure of buildings, especially on or in facades and roofs. Important breeding and resting sites are to be found not only in churches or other historical buildings, but also in industrial buildings and “standard” detached houses or apartment buildings. Technical aspects by way of examples and the legal background are summarized. Experience to date shows that those who are involved (even professionally) in construction or refurbishment procedures have very different levels of knowledge concerning species protection. In some projects, the legal requirements of species protection have been violated due to lack of knowledge. In many cases there is no sufficient and systematic examination of building applications relating to the aspects of species protection. In the county of Tübingen (Baden-Württemberg) a project was launched in 2014 to serve as a model, supported by Stiftung Naturschutzfonds Baden-Württemberg with earmarked revenues from the “Glücksspirale” lottery. The focus is on public relations, advice for architects and building clients, as well as further development of information materials. Most of the resulting materials, which are of general interest in numerous points, will be made publicly available via the website www.artenschutz-am-haus.de. Among other things, a checklist was compiled to support preliminary assessments regarding the identification of potential conflicts and further need for investigation.

Concept and implementation of vertical greening to reduce urban fine particles
Summary
Greening of urban sites is becoming more and more interesting due to increasing urbanization. On the one hand green areas are used as design elements and on the other hand greening can contribute to noise or fine dust reduction and rainwater retention. Furthermore, greening can improve the microclimate and contribute to energy saving due to insulating or cooling effects. In this paper the possibilities for vertical greening of buildings are described. Current research results concerning fine dust reduction in urban space are explained. Afterwards a new concept for vertical greening and its realization are described. Elements based on mineral materials are used in this concept. The elements are scalable and can make a contribution to the sorption of fine dust.

Urban biodiversity needs (more) space
Summary
Understanding levels of biodiversity within cities is pivotal to protect it in an era of progressive global urbanization. We here present the first meta-analysis of the drivers of intra-urban biodiversity across numerous taxonomic groups for 75 cities worldwide (Beninde et al. 2015). Our results show that patch size and corridors have the strongest positive effects on biodiversity, followed by vegetation structure. Habitat patches of at least 50 ha are necessary to maintain area-sensitive species within cities.

Evaluation of open Pine forest restoration in Börstig nature reserve, near Hallstadt (Bavaria)
Summary
This paper presents first monitoring results of restoration of open Pine forests on sandy soils in "Börstig bei Hallstadt" nature reserve, carried out by the landcare association of the district of Bamberg (Northern Bavaria). Following heavy thinning of the formally monotonous forest with removal of nearly all rootstocks and the top soil horizon, a large amount of plants and hymenopterans of open sandy habitats migrated into the cleared areas. Bembix rostrata (Hymenoptera/Sphecidae) – a suitable indicator for success – populated the new nearly vegetation-free sandy habitats. From the flora, as well as from the entomological point of view, the landcare activity has been very successful. But even in the future it is important to protect the created open areas from the regrowth of higher vegetation. Therefore, grazing with goats and sheep will be used and problematic species will be reduced mechanically. A complete list of all recorded Hymenoptera species can be downloaded under URL 1 (2015).

Nature conservation with grazing donkeys – conclusions and management implications
Summary
Dwarf Bulrush (Typha minima Hoppe), a specialist of natural riverine landscapes, is endangered throughout Europe. In Austria, Tiroler Lech Nature Park is one of only a few places where this rare plant species still occurs. More than ten years ago, a species conservation programme was initiated aimed at protecting the remaining populations and ensuring the survival of the species in the Tiroler Lech valley. In addition to reintroduction measures, we studied the genetic diversity of the remaining populations and compared it to other European populations. As Dwarf Bulrush can propagate vegetative via rhizomes, we also determined the clonality of populations. The experiences from the species conservation programme and the molecular genetic studies lead to recommendations relevant for nature conservation: if possible, plant material for reintroductions should stem from the same river system. But, because small populations can consist of only a few clones, rather large populations should serve as source populations. In ex-situ culture, seeds germinate well on sand mixtures if sown shortly after harvesting. Reintroductions were most successful with young plants and on freshly created dead branches, as well as in young side channels recharged by slope water.

Biodiversity in the classroom – a concept for the implementation of the Bavarian Biodiversity Strategy in schools
Summary
Biodiversity education is considered to be one of the most important strategies for the protection of biodiversity. Based on the existing educational policy mandate, the cornerstones of a concept for a school biodiversity education are formulated. Many topics of biodiversity make special demands on didactics and methodology and require new didactic models as well as specific skills and methods. Of particular relevance are the acquisition of knowledge about species and life forms within the context of direct encounters with nature and a cross-curricular, interdisciplinary treatment of the subject. The subject of biology plays a central role in conveying biological diversity in context; however, it requires the cooperation of all disciplines, in particular the subjects of economics, geography and social studies. The subject of geography offers an ideal way for the possibility of addressing spatial issues and landscape change. Important relationships are also found in the subjects of ethics and religion. Cooperation should be further promoted at all school levels for extracurricular environmental education, but this requires a stronger networking of all stakeholders.

Central European Habitat map (CEH) – a new high definition GIS-dataset of european habitats
Summary
Central European Habitat map (CEH) is a new helpful opportunity for trans-regional analysis within environmental monitoring or landscape planning. The high-resolution, cross-border habitat distribution map is freely available for non-commercial use. As an additional result it became clear that GIS-datasets should be better referenced between each other to facilitate such tasks in the future. A review.

Maintaining hedges in accordance with the Bavarian conservation law
Summary
Hedgerows are vital habitats for plants and provide food and shelter for wildlife, especially in intensively managed landscapes. To maintain the characteristic structure of hedges, continuous circumspective management is necessary. In cases where unsuitable maintenance equipment is used, for example to save costs, hedges and the enclosed woody plants can suffer long-lasting damage, as shown below. Such extensive damage of hedgerows is a violation of the Bavarian Nature Conservation Act and the Cross Compliance rules of the EU.

DBU-Project „Nature conservation in intensively used grassland regions“
Summary
The catchment area of the river Günz ranges from the foothills of the Alps to the Danube river and is formed by intensive agriculture. The intensification of grasslands and conversion of grasslands into fields has induced a strong loss of biodiversity and ecosystem services in this important biological corridor. With a new project co-financed by the German Federal Environmental Foundation (DBU), the Foundation KulturLandschaft Günztal tries to stop the loss of biodiversity on pastures and meadows and enhance landscape structure and diversity on this fragmented biological corridor. An important goal of the project „Nature conservation in intensively used grassland regions“ is to develop strategies for the conservation of biodiversity in regions with intensive grassland agriculture. This will be achieved through cooperative planning and implementation of measures, for example, via the bundling of compensation areas in focus areas, agri-environment measures and conservation-related income opportunities for farmers.
