The aim of the article is to present changes in forest cover within 2002—2014 in different territorial profiles. The analysis was conducted on the basis of CSO data concerning forest land, population and changes in administrative division, which were compared in relation to gminas, voivodships and urban agglomerations. The results indicate an increase in forest land area by 290000 ha in the period analysed, which implies an increase in the forest cover indicator by 0.9% across the country. The forest area per 1000 inhabitants also increased (on average by 5.7 ha in Poland). The differences in both indicators were the most visible at a lower territorial level.

Forest Lands

 Forest conversion has been identified as one of the several bottlenecks affecting upon the major infrastructure projects in Nepal, especially in the energy and transport sectors. Nepal’s policy requires at least 40% of its land cover under forest. This means if any forest land is converted to non-forest land, it must be compensated with an equivalent area, preferably in the similar ecotype in the nation. In addition, a specified number of trees must be planted for the number of trees felled in the project site, and the site must be managed and protected for five years by the developers. These provisions have led to growing resentment between the developers and the Ministry of Forests and Soil Conservation (MFSC), leading to delay in providing forest lands for infrastructure projects. With a view to develop mechanisms for the government to rapidly provide forest land for nationally important infrastructure projects, the Government databases were examined to analyze the forests handed over to the developers for non-forestry uses. The data showed that a total of 14,028.4 ha of forest area were handed over to the developers for non-forestry uses until the end of 2015. On an average, 263.8 ha forest area was found to be handed over to the developers between the period of 2010–2013. However, there is a declining trend of forest handed over for non-forestry purposes in the recent years. The decline could be due to the strict enforcement of the legal provision which limits the conversion of forest areas to non-forest areas except in the case of the “national priority projects”. It has been recommended that the conversion of forest for infrastructure development should be examined with a holistic perspective by taking all the related components of forest conversion into consideration, from providing forest land for replacement planting. It is recommended that the Forest Product Development Board (FPDB), a parastatal organization under the MFSC, should be entrusted with the work of plantation related to forest conversion. The fund for this work should flow directly from the developers to the FPDB. The possibility of forming a land bank to facilitate the work of the FPDB is also recommended.Banko Janakari, Vol. 27, No. 1, Page: 60-64

The author presents results of study concerning changes of forest area in Polish gminas and powiats in years 2008–2013. It was recognised that changes of forest area cannot be explained by both afforestation and deforestation processes only. It is important in terms of area fluctuations, eg. of private forests is secondary succession forests on abandoned former farmland as well as heterogeneous approach to the recognition of such areas in the register of land and buildings.

It is proposed to identify the hierarchy of federal districts in terms of ecological opportunities for consolidation of vegetation cover according to three classes of soil cover according to the UN classification (grass + shrub + trees) on the land territory of Russia by ranking the shares of vegetation cover and human-modified lands, as well as ecological coefficients. The total ecological coefficient is calculated by dividing the share of vegetation by the total share of anthropogenic land. The forest-agricultural coefficient is convenient as the ratio of the forest area to the arable land area. The identification method revealed stable regularities of rank distributions in the form of trends and wave equations.

Abstract The effects of defoliation caused by three foliage feeding insects, the gypsy moth (Lymantria dispar), the cherry scallopshell moth (Hydria prunivorata), and the elm spanworm (Ennomos subsignarius), on tree mortality and crown conditions were evaluated using data collected from 1984 to 1999 in the Allegheny National Forest located in northwestern Pennsylvania. While previous studies have focused on the effects of defoliation on trees in individual stands, this study differed in that it used exhaustive maps of defoliation and an areawide network of plots to assess these effects. A geographic information system was used to map the coincidence of USDA Forest Service Forest Inventory and Analysis and Forest Health Monitoring plot locations with defoliation polygons derived from aerial surveys to calculate cumulative years of defoliation for each pest. Over 85% of the Allegheny National Forest land area was defoliated at least once during the 16-year period from 1984 to 1999. Frequency of defoliation by specific defoliator species was closely associated with the dominance of their primary hosts in stands. Frequency of defoliation was often associated with crown dieback and mortality, but these relationships were not detectable in all species. These results suggest that when impacts are averaged over large areas (such as in this study) effects of defoliation are likely to be considerably less severe than when measured in selected stands (as is the approach taken in most previous impact studies).

Bukit Basa Limited Production Forest covers 125 hectares, located in Rejang Lebong District, Bengkulu Province, Indonesia.  The main function of limited production forest is to yield forest products, timber and non timber.  In Bukit Basa Limited Production Forest, there has been a change of land use from forest land to a crop land.  There has been conflict in this forest area. The objective of this study was to describe the characteristics of communities cutivating forest land and to suggest conflict resolution of this forest area. The data were collected by field observation, and interview.  The accidental sampling technique was used to select 42 respondents. Legal approaches were  used to find solutions to the tenurial conflict. The results showed that land use of Bukit Basa Limited Production Forest, in 2017 was entirely crop land. All of this forest areas have been illegaly occupied by people.  The average land area of occupied by a household was 1.24 ha. The people acquired their land by buying (4.76%), renting (21.43%), clearing the forest (42.86%), and inheriting (30.95%). The dependence of this community on the forest area was quite high. Only 38.10% of them had agricultural land outside the forest area; 61.9% depended on the land in the forest area. The contribution of farmers' incomes from agricultural business in forest land was 77.22% of their total income. The legalization of the use of limited production forests as crop lands must be enforced through policy schemes of community-based forest management, such as community forests, village forests, community plantations forest, or partnerships.

Forest land use is an activity which is committed by the community near the forest to fulfill the needs of their life. This research intended to determine factors that influence land utilization in Wan Abdul Rachman Forest Park. Utilization of forest land was assumed as the number of plant species that planted in forest land. The analysis of this research used multiple linear regressions to test factors that influence the number of plant species. This research showed that the number of plant species was influenced by duration of farming and land area size. It was revaled that longer duration of farming and larger community’s land would increase the number of plant species that has economic values.Keywords: land area, number of plant species, duration of farming, utilization of forest land.

Abstract Forests of the world constitute one-third of the total land area and are critical for e.g. carbon balance, biodiversity, water supply and as source for bio-based products. Although the terrain within forest land has a great impact on accessibility, there is a lack of knowledge about the distribution of its variation in slope. The aim was to address that knowledge gap and create a globally consistent dataset of the distribution and area of forest land within different slope classes. A Geographic Information System (GIS) analysis was performed using the open-source QGIS, GDAL and R software. The core of the analysis was a digital elevation model and a forest cover mask, both with a final resolution of 90 m. The total forest area according to the forest mask was 4.15 billion hectares whereof 82 per cent was on slope < 15°. The remaining 18 per cent was distributed over the following slope classes, with 6 per cent on a 15–20° slope, 8 per cent on a 20–30° slope and 4 per cent on a slope > 30°. Out of the major forestry countries, China had the largest proportion of forest steeper than 15° followed by Chile and India. A sensitivity analysis with 20 m resolution resulted in increased steep areas by 1 per cent point in flat Sweden and by 11 per cent points in steep Austria. In addition to country-specific and aggregated results of slope distribution and forest area, a global raster dataset is also made freely available to cover user-specific areas that are not necessarily demarcated by country borders. Apart from predicting the regional possibilities for different harvesting equipment, which was the original idea behind this study, the results can be used to relate geographical forest variables to slope. The results could also be used in strategic forest fire fighting and large-scale planning of forest conservation and management.
