Decline of Traditional Landscape in a Protected Area of the Southwestern Alps:the Fate of Enclosed Pasture Patches in the Land Mosaic Shift

【Title】【Author】【Addresses】1Traditional landscape elements such as pasture patches enclosed in a forest matrix are progressively disappearing throughout the European Alps. We assessed the land mosaic shift of a protected area located in the western Italian Alps. In particular, the dynamics of pasture patches were studied at both landscape and stand level. Land-cover mapping through object-oriented analysis of historical aerial photographs was used to assess land-cover changes between 1954 and 2000. Spatial statistics were used to quantify landscape patterns, and field samplings within pasture patches were used to explore tree regeneration structure and composition. Our results showed a significant increase in the number of pasture patches caused by their fragmentation following forest expansion. The total surface area of pasture patches decreased by 43% and their core area decreased by 94%. The encroachment of trees on less accessible areas of the pasture patches caused a reduction of patch shape at landscape scale. The gap filling process started 40-50 years ago and began with an early invasion of light demanding species like sycamore maple （Acer pseudoplatanus L.） and common ash （Fraxinus excelsior L.）, followed by European beech （Fagus sylvatica L.） and secondarily silver fir （Abies alba Mill.）. Traditional land-use and population decline in the Pesio Valley led to a reduction in ecotone areas. A transition to a more homogeneous landscape is expected in the next decades. Given the cultural and productive nature of these mountain meadow-pasture communities, extensive livestock grazing systems could be used to manage their future conservation.

Charcoal kiln sites, associated landscape attributes and historic forest conditions:DTM-based investigations in Hesse(Germany)

Background： An examination of the distribution of ancient charcoal kiln sites in the forest landscape seems to be worthwhile, since general trends in the selection of suitable kiln site locations in the past might become obvious. In this way forest landscape elements with a more intense usage by charcoal burning can be identified. By doing this, we can expect to gain information on the former condition and tree species composition of woodland. Investigations on the spatial distribution of charcoal kiln sites in relation to landscape attributes are sparse, however, probably due to the high on-site mapping effort. The outstanding suitability of LiDAR-derived digital terrain models （DTMs） for the detection of charcoal kiln sites has been recently proved. Hence, DTM-based surveys of charcoal kiln sites represent a promising attempt to fill this research gap. Methods： Based on DTM-based surveys, we analyzed the spatial distribution of charcoal kiln sites in two forest landscapes in the German federal state of Hesse： Reinhardswald and Kellerwald-Edersee National Park. In doing so, we considered the landscape attibutes ＂tree species composition＂, ＂water supply status＂, ＂nutrient supply status＂, ＂soil complex classes＂, ＂altitude＂, ＂exposition＂, and ＂inclination＂. Results： We found that charcoal kiln sites were established preferably on hillside locations that provided optimal growing and regeneration conditions for European beech （Fagus sylvatico） due to their acidic brown soils and sufficient water supply. These results are in line with instructions for the selection of appropriate kiln site locations, found in literature from the 18th to the 19th century. Conclusions： We conclude that there were well-stocked, beech-dominated deciduous forest stands in northern Hesse before 1800, particularly at poorly accessible hillside locations. These large stocks of beech wood were utilized by the governments of the different Hessian territories through the establishment of ironworks and hammer mills. Our argumentation is well in line with findings which underline that not all Hessian forests were overexploited in the 18th century. Frequently repeated complaints about ＂wood shortage＂ seemed to be more a political instrument than reality, not only in Hesse, but all over Europe. Consequently, a differentiated assessment of woodland conditions in proto-industrial times is strictly advised, even if contemporary sources draw a dark picture of the historic situation.

Novel ecosystems in the restoration of cultural landscapes of Tl’chés,West Chatham Island,British Columbia,Canada

Introduction:The small archipelago of Tl’chés,in coastal British Columbia,has gone through drastic social-ecological change culminating in the decline of traditional management practices,invasion of exotic plant species and,in the early 1960s,land abandonment.This is a common trend in cultural landscapes around the world.Cultural landscapes have great social-ecological significance,including cultural safeguarding and renewal,as well as maintenance of biodiversity,ecosystem functions and services,making them objects of special attention in conservation and restoration efforts.This study investigates the relationship between the Lekwungen people and heavily altered ecosystems in the context of ecological restoration for the cultural landscapes of Tl’chés.Methods:In order to thoroughly explore the ecological,social and cultural aspects and processes involved in the restoration of Tl’chés,this study combined different environmental sciences methodologies,including historical and archival research,semi-structured interviews and participatory observation with Lekwungen participants,as well as ecological field assessments and an innovative mapping approach termed Terrestrial Cultural Ecosystem Mapping(TCEM).Results:This study generated historical and spatial references for ecosystem and land use change in West Chatham Island,as well as cultural and ecological understandings to support restoration.Although important native species such as Camassia spp.are still thriving,present-day ecosystems on this island are heavily altered from the natural Garry oak ecosystem reference sites and are largely dominated by exotic invasive shrubs and graminoid species.This investigation indicates that the Lekwungen value both the historical ecological conditions of the island and particular types of the present-day novel or hybrid ecological states,such as the overgrown heritage orchard and nonnative berries found on the islands.Conclusions:Present-day ecosystems of Tl’chés are a result of a hybrid management system(traditional and conventional),coupled with land abandonment for many decades.Restoration of Tl’chés must involve both ecological and cultural components.Therefore,intervention strategies should consider the incorporation of novel and hybrid ecosystems(i.e.naturalized exotic species)into a restoration plan for ecological,cultural,historical,and subsistence values.

Effects of Mesopotamian Marsh (Iraq) desiccation on the cultural knowledge and livelihood of Marsh Arab women

In this study,we evaluate ecological and cultural resiliency in response to desertification of the Mesopotamian Marshes of Southern Iraq.Our research illustrates that the desiccation of the marshes has caused a drastic change in how Marsh Arab women interact with their environment;specifically,in comparison to the predesiccation period,women’s roles are increasingly limited to domestic rather than marsh-dependent activities.With the exception of raising water buffalo and limited horticulture activities,most families today have little opportunity to utilize women’s ability to generate income by applying their traditional ecological knowledge and skills.Furthermore,these women are no longer transmitting their marsh-specific knowledge and skills to the next generation,and these valuable and ancient cultural memories are being lost.Upstream dam construction,drought,and regional climate change is depriving Marsh Arab communities of marsh eco-system services such as potable water,water buffalo forage,fish yields,and reed production.In marsh areas,where enough water remains to sustain ecosystem services(such as in Chibayish and the Iraq Marshlands Na-tional Park),cultural knowledge has been retained and passed on to the next generations.We recommend that programs be implemented to preserve these traditional skills,to develop a market for handicrafts to support women and their families,and to support cultural knowledge.Otherwise,with the passing of the older genera-tion,these remnants of ancient Sumerian knowledge systems and traditional ways of life will soon be forgotten.
