Item Current problems and tasks of forest protection in Poland(Sciendo (De Gruyter), 2018-10-27) Skrzecz, Iwona; Perlińska, AldonaCurrent problems of forest protection concern the declining health of forest stands due to climate change and the resulting extreme weather events such as heat waves, droughts, hurricane winds, heavy rainfalls and floods. Repeated impacts of these factors increase susceptibility of forest stands to pest insects and fungal pathogens. Norway spruce (Picea abies [L.] H. Karst) is sensitive to high air temperatures and water shortage. Long lasting droughts during the last two decades, have been one of the reasons behind Norway spruce dieback due to severe outbreak of European spruce bark beetle Ips typographus (L.) in the mountainous regions of southern Poland. In the Scots pine (Pinus sylvestris L.) stands, water balance disorders have enhanced the colonization of weekend trees by steelblue jewel beetle Phaenops cyanea (F.) and engraver beetle Ips acuminatus (Gyll.), as well as contributed to the spread of fungal diseases caused by Gremmeniella abietina (Lagerb.) Cenangium ferruginosum Fr. and Sphaeropsis sapinea Fr. fungi. Water related stress leads to weakening of oak stands, which are attacked by Agrilus spp. beetles and pathogens from the genus Phytophthora. It is possible that long lasting droughts initiated the spread of infectious ash disease caused by Hymenoscyphus fraxineus (= Chalara fraxinea), which resulted in the epidemic of ash dieback throughout Europe. Until recently, the use of plant protection products was the most common method of forest protection against pest insects and pathogens. Poland’s accession to the European Union has affected the marketing and use of plant protection products in the country. The implementation of the EU legislation (Directive 91/414/EEC, Directive 2009/128/EC and Regulation No 1107/2009) has resulted in decreased assortment of pesticides registered for the protection of forests. High costs and long registration process considerably limited the interest of producers in placing the plant protection products on the market. Systematic decrease in the number of plant protection products possible to register for use in forestry, as well as the principles of integrated plant protection established in the EU in 2014 call for seek ing plant protection methods based on the natural enemies of pests, such as pathogenic microorganisms, parasites and predators. Therefore, contemporary forest protection requires the advancement of integrated methods for pest insect and disease control through developing methods of forecasting forest dangers, the use of natural enemies and agro-technical methods for regulation of pests, as well as the development of decision support systems as a tool facilitating introduction of integrated forest protection principles. Such support systems help to establish optimal terms for the implementation of protection measures, so as to increase their efficiency while limiting the use of chemical pesticides to an absolute minimum.Item Forest development and conservation policy in Poland(Sciendo (De Gruyter), 2020-03-31) Szramka, Hubert; Adamowicz, KrzysztofWhilst, in many countries, the scale of forest loss from business-as-usual development is immense, in Poland, this problem does not exist. However, obtaining additional land areas for afforestation is a main issue in Poland. In Poland, after the World War II, the forest area has been systematically growing. In 1945, the forest area was about 6.5 million ha, and the forest cover was 21%. In 2016, the forest area reached 9.2 million ha, and forest cover amounted to 29.5%. Today, there are 0.24 ha of forests per one inhabitant of Poland. The size of wood resources in stands is also changing. In 1945, forest resources on the trunk amounted to approximately 906 million m3, and in 2016, it reached 2.4 million m3. The problem, however, is the uneven distribution of forests in Poland. Forests in Poland are very strictly protected by law. There are two most important acts, Forest Act of 2001 and Nature Conservation Act of 2004, that regulate principles for the retention, protection and augmentation of forest resources. Over the past decades in Poland, the social demands regarding non-economical functions of forest such as recreational activities, soil and water protection and mitigation of global warming became an important and constantly growing challenge for forest managers. Thus we suggest that, first of all, it is very important to extract the leading function for a given forest area. Interactions between development and conservations policies are very tied and may suggest the need of their integration. In this article, we present the concept of development policy for forest management and forest protection in Poland.Item Plant protection and forest protection – the development of legislation and forest protection services in Poland(Sciendo (De Gruyter), 2018-05-19) Karmiłowicz, Elżbieta; Skrzecz, Iwona; Matyjaszczyk, EwaThe paper presents the history of legal changes regarding forest protection in Poland and the development of forest protection services Poland’s accession to the European Union in 2004 has affected the marketing and the use of plant protection products (PPPs) in the country. The implementation of the EU legislation (Directive 91/414/EEC) has resulted in a decline in the assortment of pesticides registered for use in agriculture, and in forestry. This situation resulted from the limited interest of producers in placing PPPs on the market. Furthermore, limitations in the aerial application of PPPs have been introduced, which has consequences for the protection of the forest, where aerial treatments are often the only way to reduce the number of pests. On the other hand, the introduction of integrated pest management (also in forestry) confirmed the adequacy of activities carried out in the State Forest National Forest Holding, where, for many decades, the prevention methods have been used to increase the resistance of stands and the multi-stage Decision Support System (DSS) is used to select the optimal protective method.Item Protection of Scots pine planting stock and forest plantations against diseases and pests in Belarus(Sciendo (De Gruyter), 2018-10-27) Prahodsky, Sergei; Kaplich, Valery; Voitka, DmitryThe aim of this research is the monitoring of diseases of Scots pine in the plantings and forest stands in the Republic of Belarus depending on the species composition of pests, their biology and the effectiveness of various methods of plant protection. Significant loss of plants for planting is associated with the spread of pathogens causing damage to seedlings, mainly from the genus Fusarium, Alternaria and Botrytis. The most abundant pests of Scots pine are Coleoptera and Lepidoptera groups representing 16 and 8 species, accordingly. Numerous species represent Curculionidae, Scarabaeidae and Tortricidae family. The main components of an effective system of measures, as an integral part of the technology of growing of planting material of Scots pine in containers, are pre-sowing seed treatment with fungicides, stimulating the growth and development of seedlings. The elaborated system of protective measures of forest plantations is based on the prevalence, phenology of pests, estimation of phytopathogenic load, monitoring of diseases and seasonal climatic conditions.
