The study of land cover and use changes is important for sustainability, given that they are part of the global changes affecting our environment. In order to understand the mechanisms determining them, land cover and use changes must be studied based on their associated transitional dynamics. The present research aims to look at the most recent land cover and use changes from Romania, chosen as an example for post-socialists transitions. The methodology was based on applying geo-spatial analyses to data on land cover and use changes and natural protected areas. The results indicate that the most prominent transitional dynamics are deforestations and abandonment of cropland, rooted in the post-socialist property restitution. Furthermore, the study identified transitional dynamics indicating the human pressure within the natural protected areas, including urbanization, development of agriculture, and deforestation. Although subject to limitations bound to the use of CORINE data, the findings are important for understanding the environmental impact of socio-economic drivers, and provide additional evidence for the fact that emerging economies tend to sacrifice the environment during the economic crises.

AbstractThe alpine region is of crucial importance for the European Union; as a result, the Carpathian Convention aims at its sustainable development. Since sustainability implies also conservation through natural protected areas, aimed at including regions representative for the national biogeographical space, this article aims at assessing the efficiency of conservation. The methodology consisted of using spatial metrics applied to Romanian and European data on the natural protected areas, land cover and use and their transitional dynamics. The findings show a very good coverage of the Alpine biogeographical region (98% included in the Convention area, and 43% of it protected within the Convention area) and of the ecological region of Carpathian montane coniferous forests (88% included in the Convention area, and 42% of it protected within the Convention area). The dominant land cover is represented by forests (63% within the Convention area, and 70% of the total protected area). The main transitional dynamics are deforestation (covering 50% of all changes area within the Convention area and 46% from the changed area within its protected area) and forestations – including afforestation, reforestation and colonization of abandoned agricultural areas by forest vegetation (covering 44% of all changes area within the Convention area and 51% from the changed area within its protected area) during 1990-2000 and deforestation (covering 97% of all changes area within the Convention area and 99% from the changed area within its protected area) during 1990-2000. The results suggest that the coverage of biogeographical and ecological zones is good, especially for the most relevant ones, but deforestations are a serious issue, regardless of occurring before or after achieving the protection status.

Abstract Marmosini species were taxonomically revised recently, however, little is known about their distribution and conservation. The aim of this research was to delimit the distribution of all species of Marmosini that inhabit Colombia, and analyze their conservation using potential distributions, protected areas, and human pressure data of the country. We used the widely known ecological niche modeling algorithm maxent to model the distribution of each species using two approaches to estimate the modeling area: a buffer-derived and an ecoregion-derived. After selecting a final model, we used data on protected areas and human pressure specific to Colombia, and analyze their conservation and pressure scenarios. Finally, we generated a species richness map for Marmosini in Colombia. We found that most species of Marmosini from Colombia co-occur at mid-elevations of the Andes with an upper elevation limit of maximum richness at ~ 2000 m. Marmosini species’ distribution covers 91% of the country's continental area, and the maximum area protected for any species of this group is between 29–5.4% of their modeled distribution. Most of the protected areas under strict and national conservation types presented small areas of high human pressure, while other categories (conservation units under managed resources and other conservation types) presented large areas of high human pressure. These species are poorly protected by the Natural Protected Areas of Colombia. Future reserves that cover Andean regions below 2000 m could help optimize their conservation.

Abstract Planning for recreational activities in protected areas involves an understanding of multiple and complex factors. Trails constitute the main recreation facility in protected areas. They are an important and common infrastructure that concentrates visitor movement. Their sustainable planning and management requires an understanding of how the visitors made their selection. The aim of this study was to identify the effect of trail attributes on visitor numbers in the Krkonoše Mountains National Park in the Czech Republic. The methods used in this study present an analytical approach involving geographic information system analysis, field monitoring and data analyses using generalised linear models. The results showed the preferential tendencies among visitors to certain trail attributes. Marginal significance and a rather strong variability in preferences (over 10%) were identified for five trail characteristics: the amount of local attractions; diversity of land cover types; dominant land cover along a trail; soil erosion; and the type of trail surface. In our study, we illustrate an analytical framework for the assessment of trail characteristics that can help guide trail analyses and management efforts. On the other hand, our findings raise new research questions and point to the requirements for further research in order to better understand how environmental attributes influence visitor choice and to use this knowledge for trail planning and management.

AbstractLand cover and use changes are an important component of the global changes, and in relationship with their transitional dynamics reflect the impact of socio-economic transition. This study is aimed at exploring the land cover and use changes occurred during 2006-2012 in Romania with respect to their spatial distribution over the regions of development and main transitional dynamics. The results suggest that the main drivers of change are deforestation and urbanization, accounting for 3/4 of all changes, and that the most affected regions are the northwest, southwest, center and northeast ones. Overall, the findings suggest a continuation of the trends from the previous periods, characteristic to transition economies.

The review contains detailed description of the «Atlas of especially protected natural areas of Saint Petersburg» published in 2013. This publication presents the results of long-term studies of 12 natural protected areas made by a large research team in the years from 2002 to 2013 (see References). The Atlas contains a large number of the historical maps, new satellite images, the original illustrations, detailed texts on the nature of protected areas, summary tables of rare species of vascular plants, fungi and vertebrates recorded in these areas. Special attention is paid to the principles of thematic large-scale mapping. The landscape maps, the vegetation maps as well as the maps of natural processes in landscapes are included. Reviewed Atlas deserves the highest praise.
