Um diesem Rückgang Einhalt zu gebieten, wurden verschiedene Artenschutzkonzepte wie das Ackerrandstreifenprogramm oder das aktuelle Programm ‘100 Äcker für die Vielfalt’ entwickelt. Für Sand- und Kalkäcker sind geeignete Bewirtschaftungsmethoden zur Erhaltung seltener Arten inzwischen gut erforscht. Für saisonal vernässte Ackerflächen, die ebenfalls viele seltene Arten aufweisen können, ist dagegen wenig über naturschutzfachlich geeignet Standortfaktoren und Bewirtschaftungsmethoden bekannt. Untersuchungen an sieben zeitweise überstauten Ackersenken bei Parstein (Brandenburg) zeigten, dass das Überstauungsregime und insbesondere die Dauer der Überstauung die Artenzusammensetzung

  • Berlin - Wikipedia
    Berlin - Wikipedia https://en.wikipedia.org/wiki/Berlin Coordinates: 52°30′26″N 13°8′45″E Berlin From Wikipedia, the free encyclopedia Berlin (/bɜːrˈlɪn, ˌbɜːr-/, German: [bɛɐ̯ˈliːn]) is the capital and the largest city of Germany as well as one of its 16 Berlin constituent states, Berlin-Brandenburg. With a State of Germany population of approximately 3.7 million,[4] Berlin is the most populous city proper in the European Union and the sixth most populous urban area in the European Union.[5] Located in northeastern Germany on the banks of the rivers Spree and Havel, it is the centre of the Berlin- Brandenburg Metropolitan Region, which has roughly 6 million residents from more than 180 nations[6][7][8][9], making it the sixth most populous urban area in the European Union.[5] Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one- third of the city's area is composed of forests, parks, gardens, rivers, canals and lakes.[10] First documented in the 13th century and situated at the crossing of two important historic trade routes,[11] Berlin became the capital of the Margraviate of Brandenburg (1417–1701), the Kingdom of Prussia (1701–1918), the German Empire (1871–1918), the Weimar Republic (1919–1933) and the Third Reich (1933–1945).[12] Berlin in the 1920s was the third largest municipality in the world.[13] After World War II and its subsequent occupation by the victorious countries, the city was divided; East Berlin was declared capital of East Germany, while West Berlin became a de facto West German exclave, surrounded by the Berlin Wall [14] (1961–1989) and East German territory.

The paper reports on the results of the pollen, plant macrofossil and geochemical analyses and the AMS 14C-based chronology of the «Rüdersdorf» outcrop situated east of Berlin in Brandenburg (Germany). The postglacial landscape changed from an open one to generally forested by ca. 14 cal. kyr BP. Woody plants (mainly birch and pine) contributed up to 85% to the pollen assemblages ca. 13.4–12.5 cal. kyr BP. The subsequent Younger Dryas (YD) interval is characterized by a decrease in arboreal pollen (AP) to 75% but led neither to substantial deforestation nor spread of tundra vegetation. This supports the concept that the YD cooling was mainly limited to the winter months, while summers remained comparably warm and allowed much broader (than initially believed) spread of cold-tolerant boreal trees. Further support for this theory comes from the fact that the relatively low AP values persisted until ca. 10.6 cal. kyr BP, when the «hazel phase» of the regional vegetation succession began.

Brandenburgische Botanikertagung fand vom 26. bis 29. Juni 2009 in Eberswalde statt, das 1859 Gründungsort des Botanischen Vereins war. Am 26. Juni leitete ENDTMANN von 14:00 bis 17:00 Uhr die Exkursion durch das Solitär- arboretum des Forstbotanischen Gartens Eberswalde (FBG), Teile des Kleinbe- standsarboretums sowie die unweit entfernte Echowiese (Klingelbeutelwiese) und deren Umgebung. Von 19:00 bis 20:00 Uhr schloss sich sein Einführungsvortrag "Landschaft und Vegetation um Eberswalde“ an. Über obige Themen kann nur sehr kurz und zusammenfassend berichtet werden. Daher sei speziell auf vertiefende Literatur und die darin zitierten Arbeiten verwiesen. 1. Exkursionen im Solitärarboretum 1.1 Kurzbemerkungen zur Geschichte des Forstbotanischen Gartens Der "Forstgarten“ Eberswalde wurde 1830 durch WILHELM PFEIL und insbesondere THEODOR RATZEBURG gegründet. Ab 1868 erfolgte die Verlegung von diesem "Pfeilsgarten“ auf die heutige Fläche. Die Entwicklung des Forstbotanischen Gar- tens wurde unter unterschiedlichen Gesichtspunkten mehrfach erläutert, vor allem durch SEELIGER (1968, 1975, 1980) und ENDTMANN (1988, 1994, 1997). Halb- schematische Karten zur Lage und Größe der Teilflächen des FBG in den Jahren 1831, 1872, 1945, 1988 finden sich bei ENDTMANN (1988, Karte 1). Hier werden auch Nachzeichnungen alter Gartenpläne des heutigen Solitärarboretums gegeben (Karten 2-8; um 1872, 1900, 1930 und 1988), weiterhin Pläne vom Kleinbestands- arboretum sowie zum DENGLER-Garten mit seinen Kreuzungs- und Provenienz- Versuchen (= Versuchen zur geographischen Herkunft). Neben schrittweisen Flächenvergrößerungen und Erhöhungen der Artenzahl wies der FBG auch tiefe Entwicklungseinschnitte auf (Stagnationen und Rück- schläge).

  • 02.07 Depth to the Water Table (Edition 2007)
    Senate Department for Urban Development 02.07 Depth to the Water Table (Edition 2007) Overview Groundwater levels in a metropolitan area like Berlin are subject not only to such natural factors as precipitation, evaporation and subterranean outflows, but are also strongly influenced by such human factors as water withdrawal, construction, surface permeability, drainage facilities, and recharge. The main factors of withdrawal include the groundwater demands of public water suppliers, private water discharge (cf. Map 02.11), and the lowering of groundwater levels at construction sites. Groundwater recharge is accomplished by precipitation (cf. Map 02.13.5), shore filtration, artificial recharge with surface water, and return of groundwater at construction sites. In Berlin, there are two potentiometric surfaces (groundwater layers). The deeper level carries salt water and is separated from the upper potentiometric surface by an approx. 80 meter thick layer of clay, except at occasional fault points in the clay. The upper level carries fresh water and has an average thickness of 150 meters. It is the source of Berlin’s drinking (potable) and process (non- potable) water supplies. It consists of a variable combination of permeable and cohesive loose sediments. Sand and gravel (permeable layers) combine to form the groundwater aquifer, while the clay, silt and organic silt (cohesive layers) constitute the aquitard. The potentiometric surface is dependent on the (usually slight) gradient of groundwater and the terrain morphology (cf. Fig. 1). Fig. 1: Terminological definition of depth to the water table at unconfined and confined groundwater 1 The depth to the water table is defined as the perpendicular distance between the upper edge of the surface and the upper edge of the groundwater surface.

  • Cultural Landscape As Action Arena – an Identity-Based Concept of Region-Building
    Regional Studies Association Annual International Conference 2011 Andreas Röhring1 Cultural landscape as action arena – an identity-based concept of region-building 1. Introduction Cultural landscapes are increasingly understood as something not merely to be protected. The European Spatial Development Perspective (ESDP) and the European Landscape Convention (ELC) as well as the new Concepts and Strategies for Spatial Development in Germany propose considering cultural land- scapes also as a force to promote cooperative regional development. Common historical roots, special landscape features, typical products, cultural traditions as well as innovative projects are possible initial points for identity-based region-building processes. In connection with governance arrangements cultural landscapes can be constituted as action arenas for regional development. These region-building processes can be understood as a special form of regionalism. The paper follows the following structure. First, the theoretical background for the constitution of cultural landscapes as identity-based action arenas will be explained (2). Next the institutional framework regard- ing new approaches to cultural landscape at the European level and in Germany will be analysed (3). Then the difficulties and synergies of the constitution of cultural landscapes as action arenas will be ex- emplified through case studies from Berlin/Brandenburg and North Rhine-Westphalia in Germany (4). Finally, some conclusions will be drawn (5). 2. Theoretical background In the following section the theoretical approach for the understanding of cultural landscapes as identity- based action arenas will be developed with reference to other ideas of regionalism and region-building. During the last decades different processes of region-building have emerged to solve new challenges of regional development.

  • Application of Inversion Modeling in Geothermal And
    Application of Inversion Modeling in Geothermal and Hydrothermal Reservoirs Alireza Hassanzadegan, Mauro Cacace, Judith Sippel, Magdalena Scheck-Wenderoth Helmholtz-Centre Potsdam - GFZ German Research Centre for Geosciences [email protected] Keywords: Geothermal reservoirs, Inversion modeling, PEST, FEFLOW ABSTRACT In geothermal reservoir studies we often have to draw conclusions and make decisions using uncertain or incomplete data sets. Reservoir studies includes modeling of all relevant geological structures, populating the model with physical and hydraulic properties and examining their evolution due to changes in pressure, temperature and applied stress. The Berlin study area is placed in the North German Basin (NGB) and its present topographic relief is the result of Pleistocene glaciations. The groundwater in the sedimentary units below Berlin is characterized by freshwater in loose sediments at shallow depth and a salty brackish to saline groundwater within the deeper sediments. Between these two different groundwater compartments a natural hydrogeological boundary is provided by the presence of an impervious clay-enriched layer, separated by a Rupel clay layer. We are using an inversion analysis approach to estimate parameters relevant for coupled heat and transport processes and to quantify the uncertainty associated while using available local data within the regional city context. The result of this study would provide a geologically consistent model useful for the assessments of the physical hydro-thermal and mechanical process occurring in the subsurface. Such a model would therefore serve as a tool to attempt a detailed study of the potential of geothermal energy application in the sedimentary units beneath Berlin. To accomplish this task we couple a commercial finite element hydro-geological code (FEFLOW) to a parameter estimation package (PEST) and we use them to characterize the uncertainty and to estimate hydraulic parameters of interest.

  • 02.12 Groundwater Levels of the Main Aquifer and Panke Valley Aquifer
    02.12 Groundwater Levels of the Main Aquifer and Panke Valley Aquifer (2014 Edition) Overview Exact knowledge of the current groundwater levels, and hence also of groundwater stocks, is imperative for the State of Berlin, since all the water for the public water supply of Berlin (approx. 206 million cu.m. in 2012) is obtained from groundwater. This groundwater is pumped at nine waterworks, almost entirely within the territory of the city. Only the Stolpe Waterworks on the northern outskirts obtains water from Brandenburg, but also supplies Berlin with approx. 9 % of the city's total intake (Fig. 1). Fig. 1: Location of the nine waterworks which supply Berlin with drinking water, as of May 2014 Moreover, groundwater reserves are tapped for individual use and for process water, as well as for major construction projects, groundwater rehabilitation measures and heating-related purposes. Numerous instances of soil and groundwater contamination are known in Berlin, and they can only be rehabilitated on the basis of exact knowledge of groundwater conditions. For this reason, the Geology and Groundwater Management Working Group produces a map of ground- water levels every month, for internal use. The map for May, the month with normally the highest groundwater level, is published in the Environmental Atlas. 1 Definitions Regarding Groundwater Groundwater is underground water (DIN 4049, Part 3, 1994) which coherently fills out cavities in the lithosphere, and the movement of which is caused exclusively by gravity. In Berlin, as in the entire North German Plain, the cavities are the pores between the soil particles in the loose sediments.
