Observed changes in the occurrence of phenological phases arecommonly considered some of the most obvious effects of climate change. However, current climate models lack a representationof vegetation suitable for studying future changes in phenology itself. This study presents a statistical-dynamical modelingapproach for Bavaria in southern Germany, using over 13,000 paired samples of phenological and meteorological data foranalyses and climate change scenarios provided by a state-of-the-art regional climate model (RCM). Anomalies of severalmeteorological variables were used as predictors and phenological anomalies of the flowering date of the test plantForsythiasuspensaas predictand. Several cross-validated prediction models using various numbers and differently constructed predictorswere developed, compared, and evaluated via bootstrapping. As our approach needs a small set of meteorological observationsper phenological station, it allows for reliable parameter estimation and an easy transfer to other regions. The most robust andsuccessful model comprises predictors based on mean temperature, precipitation, wind velocity, and snow depth. Its averagecoefficient of determination and root mean square error (RMSE) per station are 60% and ± 8.6 days, respectively. However, theprediction error strongly differs among stations. When transferred to other indicator plants, this method achieves a comparablelevel of predictive accuracy. Its application to two climate change scenarios reveals distinct changes for various plants andregions. The flowering date is simulated to occur between 5 and 25 days earlier at the end of the twenty-first century comparedto the phenology of the reference period (1961–1990).

Wissenschaftliche Grundlage für Steuerungsansätze in der Stadt- und Regionalentwicklung sollte ein verbessertes staatliches Flächenmonitoring sein, welches über die amtliche Statistik und deren Hauptindikator "Siedlungs- und Verkehrsfläche" hinaus auch die qualitative Dimension der Flächeninanspruchnahme einbezieht. Dafür stellt dieser Beitrag methodische Erweiterungsansätze für das Flächenmonitoring vor, welche kleinräumige Analysen der Zersiedelung, Freiraumstruktur, Flächenversiegelung und Ökosystemleistungen am Beispiel des Landkreises Rhön-Grabfeld aufzeigen. Diese werden im Kontext der Debatte zu Ursachen und Steuerung der Freiflächeninanspruchnahme sowie zu aktuellen Anforderungen an das Flächenmonitoring diskutiert. Betont wird deren Bedeutung für das Monitoring rechtlicher Vorgaben und politischer Ziele zur nachhaltigen Flächennutzung. N2 - In the federal state of Bavaria, there is currently intensive discussion on how land consumption for settlement and transport purposes can be reduced in the long term. In order to provide a solid scientific basis for steering instruments in urban and regional development, the official land use monitoring should be improved by including also the qualitative and structural dimension of land consumption in addition to existing official statistics and their main indicator ‘settlement and traffic area’. For this purpose, the paper presents methodological extensions, which show small-scale analyses of urban sprawl, open space structure, soil sealing and ecosystem services using the example of the district of Rhön-Grabfeld. These methodological extensions are discussed in the context of the relevant debates on the causes and steering of land consumption as well as on current requirements for land use monitoring, emphasising their importance for the monitoring of legal guidelines and political objectives on sustainable land use.

This paper analyzes the roles that research may play in relation to park–people relationships in the context of the two oldest German national parks located in Bavaria. The different fields of action of national parks are used to identify the potential for conflict, using detailed case studies from the Bavarian Forest and Berchtesgaden National Parks using quantitative population surveys carried out in 2018. The overall attitude towards both national parks is overwhelmingly positive, with trust towards park administrations and the perceived economic benefits from rural tourism being the attitudes most strongly correlated to the overall level of park–people relationships. Nevertheless, some points of contention still exist, like the ecological integrity approach towards strict nature conservation and related landscape changes (e.g., deadwood cover). A comparison over time shows in both cases that the spatial proximity to the protected area negatively influences people’s attitudes towards the parks, but less so than in the past. Recommendations for national park management include communicating proactively and with greater transparency with locals and decision-makers, to identify conflicts earlier and, where possible, to eliminate them. Furthermore, developing a standardized method to monitor park–people relationships in Germany is a must and would benefit integrated approaches in research and management based on conservation social science.

T1 - New descriptions and 2C-values of Pilosella macranthela subsp. silvae-pici (Spessart mouse-ear hawkweed) and Pilosella ottonis (Otto mouse-ear hawkweed) with an overview of the occurrence of P. macranthela taxa in Bavaria. JF - Forum Geobotanicum N2 - A pentaploid taxon from the Pilosella macranthela group was discovered in Lower Franconia/Bavaria which is newly described here as P. macranthela subsp. sylvae-pici. It grows mainly in the Bavarian Bunter Spessart and occurs with three small, isolated stands also in the limestone area of the Main valley and Tauber area. Its habit of growth is intermediate between the furcata and laxicephala types of Pilosellae with epigeal and partly hypogeal stolons and a tendency to form clusters. The upper and lower surfaces of the rosette leaves have stellate hairs. The peduncles and the phyllaries are densely covered with dark glandular hairs with yellowish glandular heads. The lateral teeth of the ligules often are separated by incisions. A tetra- und pentaploid transitional taxon between P. macranthela subsp. sylvae-pici and P. officinarum is described as P. ottonis. P. ottonis is tetra- and pentaploid with up to 7 capitula. It is densely covered with dark stalk glands on phyllaries and resembles forms of P. acutifolia in habit. The phyllaries of P. ottonis are covered with numerous epidermal papillae with a diameter of about 10–20 μm and in this aspect resemble P. macranthela subsp. sylvae-pici and P. glomerata. However, in P. officinarum epidermal papillae are absent. Plants of genetically heterogeneous tetra- and heptaploid P. macranthela have been found outside the Spessart as spontaneous hybrids between P. glomerata and P. officinarum and also occur sporadically without P. glomerata in the vicinity. N2 - Eine pentaploide Sippe aus der Pilosella macranthela-Verwandtschaft wurde in Unterfranken/Bayern entdeckt, die hier als P. macranthela subsp. sylvae-pici neu beschrieben wird. Sie wächst hauptsächlich im bayerischen Buntsandstein-Spessart und kommt mit drei kleinen, isolierten Wuchsorten auch in den Kalkgebieten des Maintals und Tauberbereichs vor. Die Wuchsform steht zwischen dem Furcata- und Laxicephala-Typus von Pilosellinen mit ober- und teils unterirdischen Ausläufern und zeigt Neigung, Horste zu bilden. Die Ober- und Unterseiten der Rosettenblätter besitzen Sternhaare. Die Korbstiele und Hüllblätter sind dicht mit dunkel gestielten Drüsenhaaren mit gelblichen Drüsenköpfen besetzt. Die seitlichen Zähne der Blütenzungen sind oft durch Einschnitte abgetrennt. Tetra- und pentaploide Zwischenarten zwischen P. macranthela subsp. sylvae-pici und P. officinarum werden als P. ottonis neu beschrieben. P. ottonis ist tetra- und pentaploid mit bis zu 7 Körben, ist an den Hüllblättern mit dunklen Stieldrüsen besetzt und ähnelt vom Habitus Formen von P. acutlifolia. Die Hüllen von P. ottonis besitzen wie die von P. macranthela subsp. sylvae-pici und P. glomerata zahlreiche, ca. 10–20 μm dicke Epidermispapillen, die stets bei P. officinarum fehlen. Heterogene P. marcanthela-Sippen (tetra- und heptaploid) kommen als Spontanhybride zwischen P. glomerata und P. officinarum auch außerhalb des Spessartgebiets vor und wurden auch ohne benachbarte P. glomerata gefunden.
