The field work was carried out in the following Forest Districts: Nowe Ramuki (Mazursko-Podlaska forest region), Płońsk, Jabłonna, Brzeziny Siedlce, Grójec (Mazowiecko-Podlaska forest region) and Skarżysko, Ostrowiec and Marcule (Małopolska forest region). In 2015–2017, sample plots were assigned and chemical as well as soil enzyme activity measurements were made in each forest stand. Samples were taken from the organic (O) and humus (A) layers and for both the acidity (in 1M KCl), content of nitrogen, carbon, sum of exchangeable alkaline cations and hydrolytic acidity were determined. The investigation of soil enzymes included the measurements of urease, asparginase, acid phosphatase and dehydrogenase activity. Coniferous trees, especially fir, spruce or larch, and mixed fir-beech and pine-beech stands were observed to have a very positive influence on the biochemical soil properties. The highest activity of dehydrogenase was observed in soils of spruce and mixed fir-beech stands, whereas it was lower in soils of beech and pine stands, and the lowest in oak stands. Oak stands were furthermore characterized by the lowest soil acidity, lowest concentration of alkaline cations, the lowest nitrogen and carbon content as well as the smallest C/N ratio. In overall, soil enzyme activity showed a significant correlation with chemical soil parameters.","PeriodicalId":35347,"journal":{"name":"USDA Forest Service - Research Papers PNW-RP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82700902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 14 documents were covered in this analysis including 13 Regional Operational Programmes of the National Forest Policy and the draft of the National Forest Programme (NFP) developed in 2000–2005, as well as nearly 300 recommendations for the “second” NFP, elaborated in 2012–2016. Very soon after the “National Forest Policy” came into force, it turned out that it needed to be adjusted to changing legal, social and economic conditions. The first attempts to revise and amend the document were made already in 2000. As a result, until 2004, 17 Regional Operational Programmes of the National Forestry Policy were developed and, on that basis, until mid-2005 a draft for a new NFP was worked out. However, the draft was neither adopted nor did it ever enter into force. The second attempt to work out the NFP was made in 2012 and resulted in the development of nearly 300 recommendations to the programme. However, to date, the NFP itself has not been finished. Most of the documents examined here refer to the current priorities of the European forest policy, and thus they would close gaps in the Polish “National Forest Policy”. In this context, the recommendations to the “second” NFP are of great importance, because they were prepared through a wide participation of various stakeholders and they refer to a wide range of problems, propose specific legal regulations, as well as indicate directions for further development of the Polish forest sector. However, the completion of the NFP is a matter of political decision that rests with the Council of Ministers.","PeriodicalId":35347,"journal":{"name":"USDA Forest Service - Research Papers PNW-RP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80073072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twelve HD3910.2 probes (three electrodes) for volumetric water content measurement were used in a distributed configuration. Modbus RTU protocols were used for data transmission and the results were archived into an internal memory. One probe delivers 1440 measurements a day. Based on the average substrate moisture data from the field, the recorder controls the watering system according to the precisely defined parameters. Proper placement of sensors in the field allows for accurate analysis of the temporal and spatial variability of peat moss substrate moisture. Results of the statistical analysis have confirmed that the peat moss moisture is significantly differentiated within the homogeneous production field of the forest seedlings. The study findings suggest that irrigation systems should be adapted to specific situation of substrate moisture at the nursery surfaces aimed at optimised water management.","PeriodicalId":35347,"journal":{"name":"USDA Forest Service - Research Papers PNW-RP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80135831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this analysis, teaching content related to forests and forestry was selected from the first three annexes of the Regulation (2017). This content is intended for children starting from the kindergarten age all the way to 8th grade as well as pupils with intellectual disabilities. In the current core curriculum, there are more topics devoted to forests and forestry than in previous analogous documents. This applies in particular to themes related to forest management, sustainable development and forest functions. Nevertheless, many topics related to biology and forest ecology remained in the curriculum, while little of the teaching content is related to threats and protection of the forest, hunting or harvesting of wood. In recent years, these have been issues that caused a number of social conflicts and controversies. Therefore, the content of forest education, which is not included in the core curriculum, should be thoroughly discussed in particular in non-formal education, because students most often have not previously been exposed to these issues. The broadened scope of themes related to forests and forestry in the current core curriculum for kindergartens and primary schools is the result of good cooperation between the State Forests and the Ministry of National Education. It would be worthwhile to continue this cooperation to implement coming changes of the above-mentioned document, supplementing the missing content as well as possible.","PeriodicalId":35347,"journal":{"name":"USDA Forest Service - Research Papers PNW-RP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78224368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 14 documents was covered in this research, including national forest programmes and forest strategies implemented in the period from 1997 to 2017. In all of the studied countries, forest policy documents were periodically revised and updated to account for changing political, economic, social and environmental conditions. As a result, at some point during the examined 20-year period, in each country the forestry priorities and goals were defined by a national forest programme. Furthermore, the vast majority of the priorities set by the European forest policy was reflected in the programmes and strategies of all the countries. Certain priorities concerning the illegal harvesting and trade of forest products, however, have not been included in the explored documents. Combating illegal harvesting of forest products and related trade is a corner stone of the EU FLEGT Action Plan and extends beyond forest policy issues of EU member states. The second corner stone is to ensure the contribution of the forest sector to a green economy, including a new concept of green economy, which still needs to be incorporated into national forest policies. Unlike Poland, in the studied countries the priorities of European forest policy have been included in single policy programmes or strategies, which define aims and goals, as well as means of their implementation in a comprehensive and coherent manner. This promotes strengthening the position of the forest sector within the national socio-economic system and supports active shaping of its relations to other sectors of the economy.","PeriodicalId":35347,"journal":{"name":"USDA Forest Service - Research Papers PNW-RP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89362367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geospatial technology is one of the advanced tools that has enormous capacity to evaluate the number of data sets simultaneously and to analyse the hidden relationships and trends. This study has evaluated the long term forest fire events with respect to India’s state boundary, its seasonal monthly trend, all forest categories of LULC and future climate anomalies datasets over the Indian region. Furthermore, the spatial analysis revealed the trend and their relationship. The state wise evaluation of forest fire events reflects that the state of Mizoram has the highest forest fire frequency percentage (11.33%) followed by Chhattisgarh (9.39%), Orissa (9.18%), Madhya Pradesh (8.56%), Assam (8.45%), Maharashtra (7.35%), Manipur (6.94%), Andhra Pradesh (5.49%), Meghalaya (4.86%) and Telangana (4.23%) when compared to the total country’s forest fire counts. The various LULC categories which represent the forest show some notable forest fire trends. The category ‘Deciduous Broadleaf Forest’ retain the highest fire frequency equivalent to 38.1% followed by ‘Mixed Forest’ (25.6%), ‘Evergreen Broadleaf Forest’ (16.5%), ‘Deciduous Needle leaf Forest’ (11.5%), ‘Shrub land’ (5.5%), ‘Evergreen Needle leaf Forest’ (1.5%) and ‘Plantations’ (1.2%). Monthly seasonal variation of forest fire events reveal the highest forest fire frequency percentage in the month of ‘March’ (55.4%) followed by ‘April’ (28.2%), ‘February’ (8.1%), ‘May’ (6.7%), ‘June’ (0.9%) and ‘January’ (0.7%). The evaluation of future climate data for the year 2030 shows significant increase in forest fire seasonal temperature and abrupt annual rainfall pattern; therefore, future forest fires will be more intensified in large parts of India, whereas it will be more crucial for some of the states such as Orissa, Chhattisgarh, Mizoram, Assam and in the lower Sivalik range of Himalaya. The deciduous forests will further degrade in future. The highlight/results of this study have very high importance because such spatial relationship among the various datasets is analysed at the country level in view of the future climate scenario. Such analysis gives insight to the policymakers to make sustainable future plans for prioritization of the various state forests suffering from forest fire keeping in mind the future climate change scenario.","PeriodicalId":35347,"journal":{"name":"USDA Forest Service - Research Papers PNW-RP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88645485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two main trends of biodiversity conservation in-situ and ex-situ are known today. However, use of both these methods is not enough for the protection of rare species of macromycetes. Therefore, we need a new method for protecting the rare species of fungi, which support their vital process in not only the laboratory but also reproducing it in nature. In this article, we propose the use of a new method of preserving the rare species of fungi in nature. The re-situ is a method that provides introducing and support of vital functions of mushroom in nature with the forming of their basidioma. For our research, we used Clathrus archeri (Berk.) Dring, which is included in the Red Data Book of Ukraine. It was found that the substrate on which the mycelium was grown and subsequently used for natural conditions had a significant influence on the success of‘reinoculation’ of C. archeri. Among all the investigated substrates, only one (beech shavings) proved to be suitable for growing of sowing mycelium of C. archeri. The research showed that the reproduction of C. archeri in nature should be held on non-forest experimental sites, mainly on meadows during the spring months.","PeriodicalId":35347,"journal":{"name":"USDA Forest Service - Research Papers PNW-RP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80264937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this paper was to determine the structure of bat assemblages in fragmented forests of central Poland (Experimental Forest Station SGGW in Rogów) based on data concerning bat fauna of this area. Our work is based on published as well as unpublished data collected between 2011–2017 and the two main methods employed during field work were: (1) evening and night bat netting, (2) detection of flying bats on transects or in points by using ultrasound detectors. 16 bat species were observed with the most common ones being serotine bat Eptesicus serotinus (Schreb.), common noctule Nyctalus noctula (Schreb.) and brown long-eared bat Plecotus auritus (l.). less numerous in overall but frequently observed in some sites were the western barbastelle Barbastella barbastellus (Schreb.) and the Daubenton's bat Myotis daubentonii (Kuhl). The following species occurred rarely: greater mouse-eared bat Myotis myotis (Bork.), Natterer's bat M. nattereri (Kuhl), whiskered bat M. mystacinus (Kuhl), Brandt's bat M. brandtii (evers.), northern bat Eptesicus nilssonii (Keys. & Blas.) parti-coloured bat Vespertilio murinus l., lesser noctule Nyctalus leisleri (Kuhl), common pipistrelle Pipistrellus pipistrellus (Schreb.), nathusius' pipistrelle P. nathusii (Keys. & Blas.), soprano pipistrelle P. pygmaeus (leach) and grey long-eared bat Plecotus austriacus (Fish.). Fragmented forests of the study area did not differ significantly in terms of bat species composition from other fragmented forests of central Poland (Płońsk Plain) nor the large forest complexes of the Bolimowska and Kampinoska Forests. In this study area, however, bat assemblages were characterized by a lower relative abundance of the common noctule and a higher relative abundance of the serotine bat as compared to assemblages in other forests of central Poland. In conclusion, the forest fragmentation near Rogów does not significantly affect bat richness and fertilized habitats are suitable for relatively large populations of species such as the western barbastelle and lesser noctule.","PeriodicalId":35347,"journal":{"name":"USDA Forest Service - Research Papers PNW-RP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77694225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on a synthetic index (Z), changes in the years 1993−2013 were evaluated for individual directorates. We identified the regions with the highest and lowest rates of change in terms of sustainable development dynamics. The analysis was performed using spatiotemporal variables and the main criterion for selecting the diagnostic variables was their availability and comparability over the analysed period. The rdSF variation was assessed with the synthetic index (Z), using the method of zero unitarisation. In 1993−2013, favourable changes over time were indeed recorded, reflecting the progress in implementing practices supporting sustainable development in forestry. However, large differences exist between the regional managements in this respect. For the analysed period, the most favourable conditions from the perspective of sustainable forest management were maintained in rdSF Kraków, rdSF Białystok and rdSF Toruń, while the least desirable conditions were found in rdSF Zielona Góra, rdSF Piła and rdSF Warsaw. The greatest rates of beneficial change, on the other hand, were found in rdSF Szczecin, rdSF Kraków and rdSF Wrocław. In turn, the lowest rates of change of the synthetic index (Z) were observed in the directorates of Katowice, Piła and Łódź. In summary, measurable indicators of sustainable development are a good instrument for measuring the pace of change in sustainable forestry. They are an effective tool for assessing and reporting progress over time and should also be used when planning and implementing development strategies.","PeriodicalId":35347,"journal":{"name":"USDA Forest Service - Research Papers PNW-RP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77791217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
