---------------------------------------------------------------------------- Call for Papers Sandstone landscapes in Europe - Past, Present and Future Second international conference on sandstone landscapes Luxembourg, 25-28 May 2005 There are many sandstone regions scattered over Europe. They host specific flora and fauna; they support landscapes where dynamic geomorphologic processes occur at rates unseen in landscapes that surround them. Pronounced geomorphologic features create strong gradients in mesoclimatic conditions and vegetation zone inversions; in addition, they generate high levels of natural disturbance and resulting patch dynamics. Recently, they have often witnessed disastrous spread of invasive species; although the true reason is unknown, it may be facilitated by the fact that these habitats support so many highly disturbed patches ideally suited for an opportunistic plant invader. All these features make them very distinct from the surrounding landscapes, both now and in the past. Much of the Holocene they seem to have supported ecosystems and species markedly different from the other landscapes; some of the species occurring there are of distinctly relict nature. Much later, when agricultural practices changed the European landscape, sandstone regions usually remained forested to a much greater degree than other landscape types. Sandstones are not only a phenomenon of geological and biological interest. Strong geomorphologic gradients forced people living there to adopt specific agricultural practices and to live in specific kinds of settlements. Bizarre andscapes of sandstone regions have attracted human attention, particularly since the Romantic period; then they became major tourism destinations with a specific settlement structure developing around an early tourism industry. We believe the uniqueness of geomorphologic and ecological processes in sandstone regions calls for a much more intimate link between geomorphology, climatology, landscape history and biology/ecology. We see this as a challenge for science: in no other landscape type botanical research would be in a stronger need for data on geomorphology, or a geomorphologist on hydrology; many similar examples can be named. A tentative list of topics that we consider really interesting may include: - Sandstone surfaces as a "memory" of past environmental processes - Formation of sandstone landscapes: deposition and erosion - Vegetation history and palaeoecology - Interaction of vegetation and sandstone relief - Sandstone regions as islands in the current landscape mosaic hosting relict species of plants and animals - Forests in sandstone regions - Case studies of individual sandstone regions: natural history, history and conservation history - History of human settlement in sandstone regions - Romantic painters' discovery of sandstone regions - Tourism - history, present impacts and future - Ecological fragility of sandstone systems in the modern landscape: effects of management change, invasive/alien species This 2nd international conference on sandstone will try to continue the effort devoted to bridging all these disciplines initiated at the 1st conference in Doubice (2002, CZ). We hope that this conference will - identify which general research topics can use sandstone regions as particularly suitable model systems (habitat islands, patch dynamics in a landscape with high disturbance rates, interactions of vegetation and climate); - facilitate comparisons of different sandstone regions over Europe and elsewhere; - establish contacts and collaboration among people interested in sandstone regions, both across different fields and over geographic space; - address conservation issues specific for sandstone regions (tourism, rock climbing, restoration management). Preliminary programme The scientific programme will consist of plenary lectures, poster sessions, workshops and excursions. All participants will be limited to one oral or poster presentation. We expect to organize the conference on 4 major topics: 1. Evolution of sandstone landscapes : geology and geomorphology Sandstone is a quite common rock type, which characterizes different regions and yet each sandstone formation differs somehow from the other by its mineralogical composition or by its origin. Today the geological evolution of these areas shows a landscape revealing many erosion features, joint patterns and rockslides from recent time, as well as a lot of elements from the geological past. The erosion often formed either narrow valleys into a sandstone plateau, or slopes of a cuesta, or buttes as residual hills or outliers... Today man takes advantage of the picturesque landscape developed in the sandstone formation through leisure and sporting activities. He extracts material for construction as sand, gravel or stone and drinking water, filtered and stocked in the underground. For a long time man took profit from the specificities of this region: of it's cliffs for protection, of it's plants for food, of it's wood for heating, of it's springs as water supply, of it's river for hydraulic power... 2. Archaeology of sandstone landscapes : from Prehistory to the Middle Ages The topic includes the various contributions of archaeology to the knowledge of the old populations within the limits given by the subject. The communications will be able to consist of syntheses, regional or correlating various European areas, or in presentations of actuality on a precise site or topic, relating to one of the following points: - the habitat and its additional activities, architecture, - burials, anthropology and taphonomy in sandy context, - petroglyphs and rupestral art. 3. Flora, fauna and microclimate of sandstone ecosystems Sandstone formations with their typical erosion features are known for special microclimatic conditions. Great variations in both humidity and temperature - including temperature inversion - are responsible for a huge diversity of plants and animals. The proliferation of Atlantic and sub-Atlantic species is remarkable, the presence of mountain and sub-mountain species is significant. Besides higher plants, the diversity of pteridophytes and the richness of nonvascular cryptogams like bryophytes and lichens of sandstone regions is in general outstanding. On the other hand, the sandstone outcrops, as well as extended woods and moist valleys offer habitats for a rich wildlife and host some rare or interesting animals. 4. Human impact on sandstone landscapes: threats and protection The sandstone landscapes aren't so frequent in Europe and it should be noted that a considerable amount of these exceptional sites became the victims of their own successes. Exploited and inhabited by man since prehistory, visited and solicited by modern man, who seeks relaxation and ventures in these spectacular landscapes, the fragile sandstone habitats are threatened more and more. The majority of the impacts and their intensity are in direct correlation with the number of visitors. Many damages are crawling and appear initially on the level of the ground, the small structures and the micro-habitats, from where the difficulty for uninitiated persons to recognize and avoid them. But, among all the threats which currently weigh on the diversity of species and ecosystems associated to sandstone landscapes, there are also some which by no means are due to the direct presence of the man. Air pollution, urban sprawl of the landscapes, genetic insulation of the species and the populations and possibly climatic change are as many serious problems and much more difficult to control and fight than the direct impacts of visitors and tourists. It is to be welcomed that persons in charge and decision makers start to recognize that sandstone ecosystems are rare and exceptional in Europe, but that they are at the same time threatened and that they thus deserve all efforts of possible safeguard and protection. Whereas the direct impacts of man are relatively quickly controllable by campaigns of information and prevention, the task will be much more difficult to avoid the indirect damages and the exit of this difficult combat will be much more dubious. Language The conference languages will be English and French. Interpretation will be provided in the plenary sessions. The conference documents will be in both languages. The conference proceedings will be in the language the long abstracts are submitted in. Call for talks and posters There will be a possibility of presenting both talks (15 + 5 min discussion) and posters. All presentations will be in plenary. We plan to organize several workshops according to the interests of the participants. If there should be too many oral contributions, preference will be given to those that fall better into the scope of the conference, whereas the remaining ones may be asked to be presented as posters.
