    Haalbaarheidsstudie ecoduct faunapassage. In de robuuste ecologische hoofdstructuur aan de oostflank van Venlo vormt de aanwezige en de toekomstige infrastructuur een knelpunt. Vanuit een offensieve benadering zijn deze ‘grijsgroene kruispunten’ echter geen knelpunt maar een kans. Met slimme meervoudige oplossingen kan meerwaarde bereikt worden voor zowel infrastructuur, natuur en andere belangrijke functies. Een ontwerpatelier heeft zes verschillende oplossingen opgeleverd, met als inzet: het realiseren van een robuuste ecologische verbinding, het verbeteren van de bereikbaarheid en het geven van een grensoverschrijdende impuls in de leefomgevingkwaliteit. In een tweede atelier is de haalbaarheid van de oplossingen getoetst, via het selecteren van criteria en doelstellingen die aansluiten bij beleid. Bestuurders toetsen de plannen en nemen het gedachtegoed verder mee.

    The increasing concentration of greenhouse gases in the atmosphere and the consequent warming of the Earth's surface presents a threat to the environment and economic development. This paper discusses how regional level impacts of transient climate change on forest growth are assessed with process-based models and how these responses are then scaled up to country and European level using national forest inventory data in combination with the European forest information scenario (EFISCEN) model. Stem wood volume and increment in the EFISCEN model is converted to whole tree biomass based on information from process-based models. Calculation of carbon in soil and in wood products is included in this approach. A preliminary carbon budget under current and changing climatic conditions, with current management regime for Germany, is presented and discussed. Although carbon stocks in trees, soil and products are increasing, we found that the German forest sector can sustain a carbon sink until 2050, but the sink gradually becomes smaller, declining from 1.7 Mg C/ha per year in 1995 to 0.7 Mg C/ha per year in 2050. This is due to ageing of forests, as sink activity in older forests is smaller than in younger forests. The sink activity in the soil increased slightly, but rate of storage in trees decreased more. Under changing climatic conditions, both carbon stock and sink activity in trees and soil were larger than under current climatic conditions. International processes, such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol require integrated assessments of the role of forests and forestry on mitigation of climate change, but there is also a need for assessments of the impacts of climate change on forests. Research can provide information for decision-makers regarding the functioning of the system, potential risks and uncertainties. The upscaling approach described in this paper will be used later to investigate the impacts of selected forest management scenarios, under current and changing climatic conditions, on the forestry carbon budgets of 27 European countries.

    Chloroplast DNA variation of oaks in western Central Europe and genetic consequences of human influences

    Oak chloroplast DNA (cpDNA) variation was studied in a grid-based inventory in western Central Europe, including Belgium, The Netherlands, Luxembourg, Germany, the Czech Republic, and the northern parts of Upper and Lower Austria. A total of 2155 trees representing 426 populations of Quercus robur L. and Q. petraea (Matt.) Liebl. were screened for polymorphism in up to four PCR-amplified cpDNA fragments. Eleven haplotypes belonging to four lineages were detected; these lineages were formerly restricted to glacial refugia in the Iberian Peninsula, the Apennine Peninsula and the Balkan Peninsula. The haplotypes originating from the Apennines are particularly well represented in the study region, but there is also a significant contribution from the other refugia, which explain the high overall level of cpDNA diversity. The strong human impact in western Central Europe during the past centuries, which has resulted in the clearance of most forests, was followed by reforestation, sometimes involving seed transfers. Despite this strong human impact, broad geographic patterns of lineages and haplotypes could still be detected. To evaluate further the consequences of the former human activities on the present day oak cpDNA genetic structure, four regions where increasingly strong human impact was anticipated (ranging from hilly regions in southern Germany to roadsides plantations in The Netherlands) were selected. There, a comparison of the levels of intrapopulation cpDNA diversity and spatial structuring was made. Over the whole area, within stand diversity was significantly higher in Q. robur than in Q. petraea (h[sub]S = 0.24 vs. 0.16). Since total diversity is identical for both species, this results in a significantly lower level of fixation for Q.robur than for Q. petraea (G[sub]ST = 0.68 vs. 0.79). The analyses also reveal a decrease of fixation with increasing human impact on oak populations. The Dutch roadside plantations (Q. robur) exhibit a very low level of fixation (GST = 0.28) as comparedto Q. petraea in southern Germany (GST=0.91). The significance of the spatial genetic structure was tested using geostatistical methods. For the complete data set, a strong spatial genetic structure is confirmed, with higher than average genetic similarities between populations distant from up to 270 km, whereas there is no spatial structure in the roadside plantations in The Netherlands or in the northern German lowlands. These results should help to differentiate introduced from autochthonous populations, and provide a framework for the identification of the geographic origin of seed lots.
