Harvesting of forested wetlands in the Atlantic and Gulf lower coastal plains has the potential to cause intense site disturbance. Often, as a result of poor pre-harvest planning, silvicultural activities are performed on wetland soils highly susceptible to rutting and puddling. Potential decreases in pine productivity have been connected with increased soil strength and decreased aeration that are commonly remnants of site disturbances associated with wet-weather harvesting.

One of the key factors in the site classification of the biogeoclimatic ecosystem classification is soil nutrient regime. Soil nutrient regime (SNR) represents the amount of essential soil nutrients available to plants over a period of several years. SNRs classes are assessed based on field identifiable (qualitative) criteria, not using quantitative measures. There have been several studies that attempted to quantitatively characterize regional soil nutrient gradients in the Coastal Western Hemlock (CWH) zone.

Abstract:
In this study we investigated the communities of soil nematodes in the forest habitats invaded and uninvaded by Fallopia japonica (Houtt.) Ronse Decr., in Tatra National Park, Slovakia. We found that invasion by F. japonica altered nematode communities and their structures. Total nematode abundance, species number and nematode biomass were significantly lower in invaded than uninvaded plots, but species diversity remained unaffected throughout the study. The overall abundance of all nematode trophic groups well represented the negative impact of F. japonica invasion on soil food webs, supporte

Abstract:
Monitoring the condition of forest belts using GIS technologies, considering their linear nature, has its own specifics. The comparison of results in calculating the areas of forest belts using different methods has shown that when obtaining preliminary data, the NDVI index is sufficient. However, in cases of significant loss in the area of forest belts, it is necessary to refine the results using manual vectorization based on satellite images. It is proposed to take into account the condition of forest belts when calculating the normative crop yield during agro-ecological soil assessment by i

Abstract:
In view of the challenges facing forest management today (global warming, increased demand for wood energy), taking account of biodiversity in forests is an immediate necessity. The aim of this work is to estimate the biodiversity of the Chettaba forest by studying these structural elements which provide indirect information on the state of biological diversity and aims to provide the first elements of an answer for the construction of a potential biodiversity index (PBI). This diagnostic tool is based on the scoring of a set of ten factors, seven of which are dependent on recent forest manage

Due to the increase in the average annual temperature and the increased frequency of forest fires leading to the death of forest plantations, our institute has developed a new method for obtaining oak seedlings characterized by high growth and development rates. Seedlings obtained by the new method are characterized by high growth and development energy accor-ding to such indicators as average annual growth, plant height, stem diameter and leaf surface index. Oak seedlings obtained by the method developed by us can be used in the repair of forest plantations with a high degree of survival and g

Abstract:
One of the central tasks of modern geography and environmental science is to determine the extent of the threat posed by soil erosion in an area and to identify the fundamental causes of the spatio-temporal variability of this process. The main objectives of this research are the following: 1) quantification of soil erosion in the Rekovac settlement; 2) multivariate analysis of selected geographical factors; 3) spatial differentiation of settlements according to the most important geographical factors. The erosion potential model (Gavrilović S. method) was applied to determine soil erosion in

The concept of marginal land (ML) is dynamic and depends on various factors related to the environment, climate, scale,culture, and economic sector. The current methods for identifying ML are diverse, they employ multiple parameters andvariables derived from land use and land cover, and mostly reflect specific management purposes. A methodologicalapproach for the identification of marginal lands using remote sensing and ancillary data products and validated on samplesfrom four European countries (i.e., Germany, Spain, Greece, and Poland) is presented in this paper.

Abstract:
The present study examines the relationships between structure (floristic composition, dendrometric parameters), diversity (diversity and evenness indexes) of urban forest park stands and the ecological (soil fertility, soil moisture), environmental factors (air pollution). The study is based on the forest park stands inventory data, performed from 2012 to 2017 in Kryvyi Rih City, Central Ukraine. The floristic compositions of the urban forest park stands are poor. There are only 23 species that belong to 14 families and 12 genera. More families were represented by at least more than 2% of tax
