It is the same and integratively traces pattern formation during succession T2 - GfÖ 43rd Annual Meeting, Building bridges in ecology, linking systems, scales and disciplines, September 9 to 13, 2013, Potsdam, Germany N2 - It is widely acknowledged that increasing complexity is a key attribute of ecosystem genesis. This is particularly true for primary succession on homogeneous substrates. However, a mechanistic understanding of spatial colonisation and pattern formation during primary succession has not been achieved yet. Thus, we studied this topic for 7 years within an experimental catchment (6 ha) established in the post-mining landscape of eastern Germany. Equidistant permanent plots (120 plots à 25m²) allowed for autocorrelation analyses, and thus tracing the spatial development of species cover performance. For each species tested, the “cover balance” first increased due to colonization, while decreasing in the course of succession. Drawing a benefit from these temporal trends, we suggested cover balance levels revealed by autocorrelation analyses to best indicate well-defined phases in primary succession at spatial entities. Hence, with the help of this spatial approach, terrestrial succession can be understood now much better at the most general level of the hierarchy provided by Pickett et al. (1987). In accordance with these authors, at subordinated levels of the causal hierarchy differential species performance might get collectively explained by contributing processes or conditions, such as ecophysiological traits, life history strategies, competition and allelopathy of the occurring plant species. Further research is needed to understand their relative contributions to the pattern formation.

T2 - Environmental Sciences Europe N2 - Background The decision of the German federal government to cease lignite mining until 2038 or—if possible— already earlier until 2030, will cause manifold transition processes in the remaining lignite mining districts of Germany. The two largest districts are located in geographically opposite regions: The Rhineland in the western part and Lusatia in the east of Germany. As particularly these two mining districts will experience severe changes in their socioeconomic as well environmental conditions, the federal government has adopted comprehensive economic support measures. However, the environmental changes will also cause altered ecosystem functions and services to be provided by the future post-mining landscapes. Results In this paper, the two main lignite-producing regions of Germany are compared with regard to their natural and cultural settings. The economic situation and its history are reflected and differences are outlined. Part of the disparities in the cultural development can be explained by very different natural conditions, especially edaphic factors and climatic situation. Because of dissimilar geological settings, different mining technologies were developed and are in use in the two regions with distinct effects on the resulting post-mining landscapes. Conclusion The long-standing and manifold lignite mining activities have radically restructured the landscapes in Lusatia and the Rhineland. With the ongoing decline of the mining industry and its complete cessation, presumably within the next decade, both regions will alter their faces significantly. These changes offer both challenges but also opportunities with respect to the post-mining landscapes and their ecosystem services they are going to provide. The prerequisites for a positive socioeconomic development and for sustainable land-use concepts that also consider ecological aspects are different for both regions. However, or especially because of these differences, the knowledge exchange and experience transfer between both mining regions are pivotal for the success of this extensive transformation process.

T1 - Factors impacting the variability of post-fire forest regeneration in central European pine plantations T2 - Restoration Ecology N2 - Fire is increasingly posing a risk to forests and plantations, even in the temperate latitudes of central Europe. Little is known about fire ecology in this region, and therefore, appropriate approaches for the management and reforestation of burned sites are mostly lacking. In a Scots pine plantation region in Brandenburg (northeast Germany), the early tree regeneration of two nearby areas that burned 1 year apart was investigated. We observed that 3 years after the fire events, the forest in one study area showed a relatively high regeneration with a mean density of 7765 saplings/ha, clearly dominated by European aspen (93%); whereas the other study area showed a lower mean density of 5061 saplings/ha, dominated by Scots pine (71%) and aspen (15%). Three years after the fires, the difference in aspen density was 11-fold between the two areas. We studied the effects of several variables about soil and environmental properties on the aspen establishment in these two study areas in the second and third years after the fire events. We found that the post-fire aspen regeneration was influenced by several factors, including soil texture, soil disturbance from forest management, volume of deadwood, and browsing. We also discussed that weather conditions during seed production and germination might have played a role in the difference in aspen establishment between the two study areas. We concluded that the post-fire forest regeneration potential in the study region is highly variable and could come under critical pressure as climate change progresses.

Basis dieser Annahme waren Berichte von Archäologen und Restauratoren aus Museen und Denkmalpflege ganz Deutschlands, dass der Erhaltungszustand von neuen Eisen- oder Bronzefundstücken zunehmend schlechter werde. Um dem vermuteten Zusammenhang mit Umweltbelastungen nachzugehen, rief die Deutsche Bundesstiftung Umwelt Mitte der 1990er Jahre das interdisziplinäre Projekt „Schutz archäologischer Metallfunde vor immissionsbedingter Schädigung“ ins Leben. An verschiedenen archäologischen Fundstätten in der Bundesrepublik Deutschland wurden archäologische Metallfunde untersucht und parallel dazu Bodenuntersuchungen durchgeführt, um etwaige Umwelteinflüsse feststellen zu können. Die Ergebnisse des Gesamtforschungsvorhabens sind in einem umfangreichen Band zusammengefasst1. Als ein mit Wald bedeckter Standort wurde der Döttenbichl, oder Döttenbühl, bei Oberammergau in die Untersuchungen mit einbezogen, auch weil vor allem die dort gefundenen Eisenobjekte unerwartet gut erhalten waren. Im Folgenden sollen die Ergebnisse der bodenkundlichen Untersuchungen an diesem Standort zusammengefasst werden, für die am 7. Mai 1996 Bodenproben genommen wurden.

The two largest lignite mining areas are located in geographically different regions: Rhineland in the west and Lusatia in the east. As the socio-economic and environmental conditions in these two mining areas are set to change dramatically, the German government has adopted extensive economic support measures. However, the environmental changes will also lead to changes in the ecosystem functions and services provided by the future post-mining landscapes. Gerwin et al. (2023) compare the two main lignite producing regions of Germany in terms of their natural and cultural environments. The economic situation and its history are reflected and differences are outlined. Part of the differences in cultural development can be explained by the natural conditions, especially the edaphic factors and the climatic situation. Because of the specific geological settings, tailored mining technologies were developed and used in the two regions, with different effects on the resulting post-mining landscapes. We conclude that the landscapes of Lusatia and the Rhineland have been radically restructured by the long and varied history of lignite mining. Both regions will change significantly as the mining industry continues to decline and is expected to cease altogether within the next decade. These changes in the post-mining landscapes and the ecosystem services will provide both challenges and opportunities. The preconditions for positive socio-economic development and for sustainable land use concepts that also consider ecological aspects are different for the two regions. The exchange of knowledge and experience between the two mining regions is crucial to the success of this major transformation process, despite, or perhaps because of, these differences.

Obwohl die Genese der auf diesen Flugsanddecken anzutreffenden Böden bereits seit bis zu 1 000 Jahre andauert, sind hier erst Böden der Klasse der Ah/C-Böden entwickelt. Auf den Bergbaufolgestandorten wird versucht, die Bodenbildung durch spezielle Meliorationsmaßnahmen zu fördern. Untersuchungen an diesen besonders jungen Böden lassen gut die Prozesse der initialen Bodenentwicklung erkennen.

To enhance the value of such marginal lands for a future regionally based bioeconomy the EU funded BeonNAT project plans the plantation of regional tree and shrub species. The obtained forest biomass will be used for the production of biodegradable bio-based products and bioactive compounds that will play an important role to replace fossil-based competing substitute products. Field trials in different European countries will be established to test the benefit of intercropping/mixed-forest in marginal cultural land versus the natural growing/monoculture. In Germany, one test site is located in the post-mining sites of Lusatia. In this field trial the biomass development, the impact on soil fertility and biodiversity will be investigated after planting Robinia pseudoacacia and Rubus fructicosus.
