Diciembre, 2014
Eslovaquia

The paper solves evaluation of current state of accessing the forest with forest road network in the forest management unit Čierny Váh, evaluatation the state of forest roads, point out shortcomings in accessing the forest and eventually propose optimal solutions to improve the situation in the area of interest. Thesis describes natural conditions of the area of interest.

Wolves adapt territory size, not pack size to local habitat quality

Journal Articles & Books
Diciembre, 2015

Although local variation in territorial predator density is often correlated with habitat quality, the causal mechanism underlying this frequently observed association is poorly understood and could stem from facultative adjustment in either group size or territory size. To test between these alternative hypotheses, we used a novel statistical framework to construct a winter population‐level utilization distribution for wolves (Canis lupus) in northern Ontario, which we then linked to a suite of environmental variables to determine factors influencing wolf space use.

Impacts of internal and external policies on land change in Uruguay, 2001–2009

Policies play a pivotal role in determining land change. Uruguay has been subject to first a rise and then decline in plantations of exotic trees as a result of internal Uruguayan government policies, and a recent substantial increase in soybean cultivation that may be attributed to Argentinean policies. To properly assess the relationship between land change and changes in land-use policies, vegetation change for Uruguay from 2001 to 2009 was mapped using MODIS imagery.

Patterns of black grouse, Tetrao tetrix distribution in northwestern Russia at the turn of the millennium

We have studied the relationship between landscape structure and black grouse density in Russian Karelia and compared it with East Finland. The spatial density distribution of the black grouse population is relatively even, especially in areas with a high proportion of forest land. Correlations between forest structure and black grouse abundance were generally low. We found three significant correlations for Russian Karelia: positive for clear cuts and young forests and negative for the proportion of old forests.

Reducing emissions from deforestation and forest degradation in developing countries (REDD+) is regarded by its proponents as one of the more efficient and cost effective ways to mitigate climate change. There was further progress toward the implementation of this mechanism at the 16th Conference of Parties (COP) in Cancun in December 2010. Many countries in southern African, including South Africa, have not been integrated (do not participate) into the UN-REDD+ programme, probably due to their low forest cover and national rates of deforestation.

TO THE QUESTION ABOUT THE FORMATION AND SIGNIFICANCE OF AGROFORESTRY FRAME OF THE ORENBURG REGION

Journal Articles & Books
Diciembre, 2016

A large-scale project – “The Stalin plan to transform nature" of 1948 changed the landscape of the Orenburg region. Inthe second half of the twentieth century in the region laid the foundations for the modern scheme of agroforestry frame. Thebasis of agroforestry frame of the Orenburg region became the State protective forest strip in the direction of the Vishnevayamountain – Chkalov – Uralsk – Caspian sea along the banks of the Ural river, a distance of about 1080 km. Treeless areas(less than 1%) mainly concentrated in the east region with average extent of forest cover of 0.5%.

Overview of national inventories for the LULUCF sector

Conference Papers & Reports
Diciembre, 2011

Under the United Nations Framework Convention on Climate Change (UNFCCC), Annex I countries that are Parties to the Climate Change Convention provide annual greenhouse gas (GHG) inventory submissions including GHG data for the land use, land-use change, and forestry (LULUCF) sector. For many countries, carbon sequestration – especially in Forest Land-offsets a significant proportion of national emissions both an-nually and overtime.

Voting methods in strategic forest planning -- Experiences from Metsähallitus

Journal Articles & Books
Diciembre, 2008

Voting methods were used by Metsähallitus in a real strategic participatory planning case in a regional working group context. The general aim of the study was to find out whether learning and collaborative decision making could be adequately supported by using the voting methods in the regional stakeholder group.

Factors determining soil nutrient distribution in a small-scaled watershed in the purple soil region of Sichuan Province, China

China

Determining soil nutrient distribution is critical to identify sites which are at risk of N and P loading. Equally important are determining factors that influence such distribution (e.g. land use, land management, topography, etc.). In this research, soil nutrient distribution and its influencing factors were studied in a small-scaled watershed in the purple soil region of Sichuan Province, China. The watershed is 1.3km² with a complex land management system including agriculture and forestry.
