Protected areas are crucial for biodiversity conservation because they provide safe havens species threatened by land-use change and resulting habitat loss. However, protected only effective when stop loss within their boundaries, connected via corridors to other wild areas. The effectiveness of is development; however, the extent this threat unknown. We compiled spatially-detailed housing growth data from 1940 2030, quantified each wilderness area, national park, forest in conterminous...
An increasing number of studies have reported on forest declines and vegetation shifts triggered by drought. In the Swiss Rhone valley (Valais), one driest inner-Alpine regions, species composition in low elevation forests is changing: The sub-boreal Scots pine (Pinus sylvestris L.) dominating dry showing high mortality rates. Concurrently sub-Mediterranean pubescent oak (Quercus pubescens Willd.) has locally increased abundance. However, it remains unclear whether this local change part a...
Abstract. European forest use for fuel, timber and food dates back to pre-Roman times. Century-scale ecological processes their legacy effects require accounting management when studying today's carbon sink. Forest reconstructions that are used drive land surface models one way quantify the impact of both historical large scale application on forest-related sink climate. In this study we reconstruct from 1600 2010 making diverse approaches, data sources assumptions. Between 1828, a...
In the dry Swiss Rhone Valley, Scots pine forests have experienced increased mortality in recent years. It has commonly been assumed that drought events and bark beetles fostered decline, however, whether beetle outbreaks years they can be linked to stress or increasing temperature never studied. our study, we correlated time series of indices from long-term climate stations, 11-year trends a research plot, probabilities modeled tree rings (as an indicator vitality) with documented...
Abstract The paper presents the outcomes of uncertainty investigation a long-term forest cover change analysis in Polish Carpathians (nearly 20,000 km 2 ) and Swiss Alps 10,000 based on topographic maps. Following Leyk et al. (2005) all possible uncertainties are grouped into three domains - production-oriented, transformation- oriented application-oriented. We show typical examples for each domain, encountered during discuss consequences detection. Finally, proposal reliability assessment...
Abstract Changes in forest use are considered as a potential key driver for recently observed changing dynamics the pine belt of upper Rhone valley (Canton Valais, Switzerland). In this region, traditional non-timber uses, such litter harvesting and wood pasture, were practised until second half twentieth century. The practice uses led to specific environmental conditions which favoured pioneer species. With abandonment these practices was subjected increased competition largely replaced by...
This study aimed to obtain accurate binary forest masks which might be directly used in analysis of land cover changes over large areas. A sequence image processing operations was conceived, parameterized and tested using various topographic maps from mountain areas Poland Switzerland. First, the input were filtered binarized by thresholding Hue‐Saturation‐Value colour space. The second step consisted a set morphological procedures leading final masks. then assessed compared manual boundary...
