Opis:
Bezzałogowe Statki Powietrzne - z początku traktowane jako „zabawka”, z biegiem czasu i postępu technologicznego stały się pełnoprawnym narzędziem wykorzystywanym w gospodarce, w tym w leśnictwie i ochronie środowiska. Możliwości techniczne BSP pozwalają im, poza lotami kierowanymi przez operatora, na wykonywanie lotów autonomicznych (po zaplanowanej trasie) z ładunkiem dochodzącym do kilku a nawet kilkunastu kilogramów. Wyposażone w różnego rodzaju urządzenia rejestrujące mogą być wykorzystywane w ochronie przeciwpożarowej, ochronie przyrody, ochronie i hodowli lasu, gospodarce łowieckiej, urządzaniu lasu. Dodatkowym atutem używania BSP w wielu dziedzinach gospodarki jest niski koszt użytkowania w stosunku do lotnictwa załogowego oraz duża mobilność urządzeń. Dzięki podglądowi obrazu na żywo BSP umożliwiają obserwacje sytuacji niebezpiecznych takich jak pożary lasów, oszukiwanie zaginionych osób czy rozmaite akcje ratunkowe. Ograniczeniem w stosowaniu BSP są zapisy prawa lotniczego, zezwalające na komercyjne wykorzystanie BSP przez osoby posiadające świadectwo kwalifikacyjne operatora BSP w lotach wykonywanych w zasięgu wzroku.
Unmanned Aircraft that initially was treated as a “toy” in time and with technological progress have become a rightful tool used in economy including forestry and environment protection. Technical potential of unmanned aircraft allow them, but for operator-controlled flights, to perform autonomic flights (a planned route) with a cargo of a few or even a few dozens of kilograms. The aircraft being equipped with various recording devices can be used for purposes of fire protection, environment protection, protection and cultivation of forests, wildlife management, and forest arrangement. The use of unmanned aircraft in economy offers yet another advantage, namely a low cost of use compared to manned aviation as well as large mobility of devices. Thanks to live preview image unmanned aircrafts allow to observe dangerous situations such as forest fires, looking for missing people or other various rescue operations. The use of unmanned aircraft is limited by regulations of aviation law that allows only the commercial use of the aircraft by persons having a qualifying certificate of an unmanned aircraft operator in flights performed in view.

Opis:
The aim of this paper was to evaluate the financial and economic resources efficiency of forest districts in the years 2008−2012 using a nonparametric approach of the Data Envelopment Analysis (DEA). DEA is a linear programming based method for evaluating the performance of comparable production units such as firms. The relative efficiency of compared forest districts is calculated with the Variable Returns to Scale (VRS) model. Although the method is already extensively applied in many areas of economics, its use in forestry remains limited. We studied 110 forest districts from Wrocław, Katowice, Kraków and Krosno regional directorates of the State Forests. The research was conducted in groups of forest districts according to the similar forest site type, which ensured the homogeneity of the units and the comparability of research results. Two categories of the forest districts were identified: ‘lowland' and ‘upland−mountain' ones. The study covered selection of input (efforts) and output (results) variables as well as selection of appropriate DEA model, which were used to evaluate technical efficiency of the forest districts. Within the so−called model of economic resources they were quantified in technical units, whereas in a financial model – in value terms. The research shows differences in the use of economic and financial resources by the analyzed forest districts. The ‘lowland' were more effective than ‘upland−mountain' ones both in terms of the use of the financial and economic resources. Average relative efficiency in a financial model for the ‘lowland' forest districts amounts to 0.896, while for the ‘upland−mountain' ones – to 0.839. In economic resources model this parameter equals 0.853 and 0.823, respectively. The DEA method may be an alternative or complementary to other methods of evaluation of the forest district efficiency. Any attempt of such analysis may be very valuable support in the forest management.

Opis:
Ongoing climate change will likely expose trees and forests to new stresses and disturbances during this century. Trees naturally adapt to changes in climate, but their natural adaptive ability may be compromised by the rapid changes projected for this century. In the broad sense, adaptation to climate change also includes the purposeful adaptation of human systems, which includes forestry. In this article, we briefly review the expected impacts of projected climate change on trees and forest ecosystems in Poland. We further provide a framework for designing adaptive strategies to sustain or enhance forest growth, health, and ecosystem services in new climates. Within this framework, we distinguish two related objectives: (1) adaptation of decision−making process in forest management and (2) adaptation of forest ecosystems. Each of these objectives may be achieved through strategies and options whose applicability is discussed in relation to major forest functions – ecological and societal, commercial, and multiple−use. Knowledge gaps and research needs are also identified. We conclude that the recent emphasis on sustainable multifunctional forestry and the current ownership structure in Poland will facilitate adaptation of Polish forests to future climates. However, much remains to be learned about the impacts of climate change, especially at the ecosystem level. Cooperation between researchers and forest managers is critical for developing better management strategies for adapting forests to climate change.

Opis:
The paper presents the history of approaches to forest management derived from the idea of forest sustainability, as well as its inspirational role in the formulation of the concept of sustainable development of forests. The promotion of this concept in forestry is the responsibility of forest management planning through the modification of forest management plans and adaptation of the principles of conducting forest management to changing realities. Changes in planning, both in terms of time and space, are necessary especially because of the reconsideration of the range and significance of forest functions. The development of the ‘normal forest’ model and management unit−level methods of forest planning was a key event in the history of forestry in Europe. The development of knowledge, as well as economic, technological and social changes were conducive to the emergence of new theories on the production intensification and to use the economic criteria for determining the rotation age. This also referred to the need to develop an appropriate forest structure to ensure the sustainable use of forest resources. As regards determination of the harvest level, the development of the stand−level method of forest management published by Judeich in 1871 is worth noting. Recent results of the research on forest habitat and productivity have revealed the problem of forest species composition and the importance of forest tending activities. Another group of research achievements cover the new systems of determining the allowable cut taking into account forest maturity and sustainability criteria. In the multiple−use forest model being implemented in Poland, forest utilization is to be treated as a realization of all forest functions expected by society. Accordingly, two functions of forest use can be distinguished − the temporary function aimed to satisfy the current demand for timber, and the strategic function to secure a relatively steady, long−term timber supply, as well as to improve the condition of forest resources. The idea of the modification of the principles of deter− mining the volume of harvest, meeting the set requirements, is a continuation of the above issues. The changes taking place in the conditions of the planning process in forestry over the last decades have caused its continuous extension in terms of range and interdisciplinary areas. The principles of forest use, renewal, tending and protection create a logical and chronological sequence of events showing the complexity of the problems that appear at the stage of planning and in the forest district practice. The current problem at the stage of forest planning is the effect of climate changes on forest ecosystems and possible measures to counteract them. When creating forest management plans, the adaptation activities related to forest management are gaining importance.

The paper presents the method of determining the management difficulty index for forest ranges of the State Forests To assess the management difficulty level, a set of 16 sub−indices was developed characterizing terrain obstacles, the structure of and threat to forest resources, as well as the extent of management tasks. The annual work time structure of range forest managers was a basis for the point rating of individual sub−indices. The usefulness of the method was proven in the management practice of the State Forests.

The paper contains the results of studies relating to the construction of the future strategy for development of forests and forestry, which were based on reports relating to the condition of forests and forestry, and the results of the last inventory of forests in Poland. It was found that realisation of the forest management by State Forests is correct and consistent with the principles of sustainable development and principles of the development of multifunctional forest. It is also static, without the proposal of innovative solutions, under−performing both its economic strength and accumulated intellectual capital and practical experience.
