An integrated direction system for forest management in the form of theses into the forest acts

Publié en ligne: 07 Mar 2014
Pages: 221 - 228

Résumé

Abstract

The paper presents basic conception (system) of long term and sustainable forest management. Forest benefits divides into timber production and provision of public functions. It characterizes a new categorization of forests. The basic forest feature and also the basic forest management feature is a long- -term. Therefore, it is necessary to develop such a system of a long-term planning, resulting in forest management plan. The paper presents main principles of long-term forest management development. It defines consequent key decisions (determining the forest category, management targets, management method, deriving the allowable cut, etc.). At the end, it presents the control system of management that should ensure improvement of the whole long-term process of forest management. It involves a complex concept of long-term and sustainable forest management development, with a practical application in a view of management system into the forest legislation, especially, the new forest act

Impact of soil drainage to the radial stem growth of Norway spruce (Picea abies L. Karst.) in peatland forests

Publié en ligne: 07 Mar 2014
Pages: 240 - 247

Résumé

Abstract

Peatland Norway spruce (Picea abies L. Karst.) forests represent very valuable ecosystems with considerable importance for nature conservation. However, a lot of peatland forests have been drained or used for opencast mining of peat. Since dendrochronological and dendroecological studies on trees growing on peatlands in Europe are not many, this study aimed to reconstruct the impact of drainage to the growth of trees in forest stands older than 100 years in the moment of drainage. Dendrochronological analysis was performed on two 0.25-ha square sampling plots (50*50 m) in two pre-selected stands (control site vs. drained site) with similar natural conditions and age. The mean-value functions of the ring indices, comparing the drained site with the control site, in the period after 1940 revealed very similar radial-growth trends. After the year 1992, when one site was substantially drained, the radial-growth trends not showed any significant change. Likewise, the result of the independent two sample t-test for the period after 1992 has not revealed any substantial statistically important difference in the mean index between the control site and the drained site
