Motivations and Land-Use Intentions of Nonindustrial Private Forest Landowners: Comparing Inheritors to Noninheritors

Journal Articles & Books
December, 2009

The documented importance of intergenerational human capital transfers in agriculture generally gives us reason to suspect that such transfers may be important in a forestry context and that there may be important implied differences between first-generation woodland owners and multigeneration woodland owners with respect to their motivations and future intentions.

Carbon Leakage with Forestation Policies

Conference Papers & Reports
December, 2011

This paper analyzes carbon leakage due to reduced emissions from deforestation (RED). We find that leakage with RED is good because the policy induces afforestation that contributes to a further carbon sequestration. By ignoring the domestic component of carbon leakage, the literature can either overestimate or underestimate leakage, depending on the magnitudes of the numerator and the denominator of the leakage formulas. Unlike the literature, we include the land and agricultural markets in the analysis of carbon leakage with forestation policies.

Quantifying surface albedo and other direct biogeophysical climate forcings of forestry activities

Journal Articles & Books
December, 2015

By altering fluxes of heat, momentum, and moisture exchanges between the land surface and atmosphere, forestry and other land‐use activities affect climate. Although long recognized scientifically as being important, these so‐called biogeophysical forcings are rarely included in climate policies for forestry and other land management projects due to the many challenges associated with their quantification.

Cercetari privind regenerarea sub masiv si introducerea la adapostul masivului a unor specii autohtone valoroase, in arborete apropiate de exploatabilitate, de pe terenuri degradate

Journal Articles & Books
December, 2004

Researches made in the most important part of protection plantations reforested on land degradation showed that the basic species is Pinus nigra and/ or Pinus silvestris replacing some stands with Hippophae associations. This stands have a fragile structure, not so good for protection functions. Sheltered regeneration and reforestation with local valuable species represents an efficient method for increasing the stability of stands in the reforestation of land degradation. In this way the degradation process was stopped and the vegetation was reinstalled.

Study on the diurnal change of microclimate and human comfort in five types of land covers

Journal Articles & Books
December, 2013

The role of urban parks in the microclimatic conditions of cities in summer is investigated in this paper through monitoring campaigns carried out at the Beijing Olympic forestry park. Five kinds of land cover, namely urban woods, lawn, bare concrete cover, water areas and wetlands were selected to study on the temperature, humidity and human comfort. The air temperature and relative humidity were measured once every two hours from 8:00 to 20:00 every day and continuously three days in July 2010.

The effect of low-value forest stands reconstruction on hydro melioration systems on the environment in Kadnikovski forestry enterprise in Vologda region

Journal Articles & Books
December, 2014
Russia

Woodless areas after clear cutting and fires are subjected to periodic water logging resulting thereby in water logging. The reconstruction of low-value forest stands (LVFSR) should become an effective measure for forest management on such areas. The experimental industrial station was the object of the study. It was founded by the Vologda laboratory of the Northern Forestry Research Institute. The LVFSR was carried out by means of planting and care of it. The total area of the low-value forest stands development of the open and shrubs overgrown territories was 42 hectares.

Designing mosaic landscapes for Black Grouse Tetrao tetrix using multi‐scaled models

Journal Articles & Books
December, 2013

With increasing pressures on land for human use, it is important to identify the habitat requirements of key species, not just in terms of a correlation with a given habitat feature, but also the relationship between species presence and its coverage, proximity to other habitat types, and importance at different spatial scales. We used maximum entropy to estimate the optimal proportions of 18 habitat types, plus elevation and habitat richness associated with the presence of leks of Black Grouse Tetrao tetrix within an 800‐km² study area in Perthshire, Scotland.

Forest land transformation in Latvia: resume of the PhD paper for the scientific degree of Dr.silv. in Forest Economic and Policy

Policy Papers & Briefs
December, 2008
Latvia

The Promotional Paper Forest Land Transformation in Latvia by Gunta Bāra has been developed at the Forest Faculty of the Latvian University of Agriculture between 2001 and 2007. Goal of the Promotional Paper: to identify the main problems in transformation of forest land in the Republic of Latvia and gaps in legislative instruments regulating the process of change of land use type, to prepare recommendations for their elimination, to develop a methodology for calculation of compensation for the losses caused to the state as a result of destruction of natural forest environment.

Optimalization of forest access by forest road network in forest management unit Čierny Váh

Journal Articles & Books
December, 2014
Slovakia

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
December, 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.
