Chełmno Land
Opis:
The settlement established under German law in Chełmno Land in the 13th century, the resultant changes in the structure of agriculture and land cultivation techniques, and the growing demand on wood as timber, fuel and raw materials for crafts, all combined to contribute to the significant deforestation of the territory. The extent of this deforestation remains conjectural. The purpose in creating a model of forest area in 13th-century Chełmno Land was to attempt to reconstruct it and determine its size and, consequently, to verify hypotheses concerning the scale and the ultimate end of deforestation in the research area. The spatial model is based on published historical and archaeological data relating to selected components of the geographical environment that pertain to the forest area. A retrogressive method combined with Multi-Criterion Evaluation (MCE) was used to build a forest area model. The basic platform for collecting, analysing and visualising spatial data was the geographic information system (GIS). The presented estimates indicate that the forest area of Chełmno Land in the 13th century was larger than had previously been assumed, at about 20–25% of the entire territory.

Opis:
Soil environment, both biotic (e.g., microbial community) and abiotic (e.g., nutrients and water availability) factors determine soil fertility and health and are directly affected by soil management systems. However, only limited studies evaluate the combined effect of nutrients availability and soil disturbance on the soil bacteria community structure, especially in conventional agricultural practices, on the forests converted to agricultural land. This study aimed to provide a viewpoint of the effect of different soil management systems, i.e., forest soil (natural process) and tilled land, on soil bacteria community structure on forest converted to agricultural land, according to a metagenomics approach. Moreover, each land use was sampled to identify the bacterial community using 16S gene as a biomarker. The sequencing was performed using MinION (Oxford Nanopore Technologies) to read the DNA sequence from each soil sample. Principle Component Analysis (PCA) was performed to comprehend the relationship between availability of nutrients and bacterial diversity. The results revealed that the concentrations of soil micronutrients, such as iron, zinc, and magnesium, were significantly higher in forest soil than in tilled land. According to diversity indices, soil bacteria were more diverse in forest soil than in tilled land. Forest soil had more distinctive taxa than tilled land. Several species comprised the most abundant taxa, such as Candidatus Koribacter versatilis, Candidatus Solibacter usiatus, Rhodoplanes sp., Luteitalea pratensis, and Betaproteobacteria bacterium, were more scarce in tilled land. On the distinctive taxa in each soil sample, Anseongella ginsenosidimutans and Janthinobacterium sp. were the most abundant species in forest and tilled land, respectively. According to PCA analysis, soil management system affected the soil micro-and macronutrients also microbial community structure between forest and tilled land. In conclusion, soil management influences the essential nutrient content and bacterial community structure of soil. Better management should be adopted to maintain soil quality near forest soil.

Opis:
Sustainable forest management, the leading topic in forest and environmental policy since the 1990s, has required an appropriate tools for both clarification of general principles and measurement of its progress. Many of indicators developed for these purpose are based on forest area. However, definitions of forest are not compatible, especially on national and worldwide scale. Definition of forest applied by FAO refers to crown cover and land use, while definition adopted for reporting under Kyoto Protocol refers only to the occurrence of trees. Polish Act on Forest applies the destination of land use as a determinant of forest. Paper analyses the process of forest area assessment in Poland for the purpose of national as well as FAO and UNFCCC reporting. Natural expansion of trees on abandoned agriculture land, still classified as the agriculture areas in cadastral system, was recognized as the biggest challenge of forest area assessment in Poland. Although natural succession is described by many authors, the total area subjected to this process is unknown. According to the FAO and Kyoto Protocol rules such areas should be reported as forests. As a consequence, forest area in Poland could be at least a few hundred thousand hectares higher than reported in the last assessments basing only on cadastral system. The proper classification of forests not recorded in the cadastral system would also be important challenge, otherwise between forest area on country and international level will be a huge discrepancy. But, there are some areas classified as a forest in Poland, which probably should not be included within FAO and Kyoto reporting. However, the most important topic concerns the possibility of identification of afforested areas, submitted under article 3.3. of Kyoto Protocol, basing on forest area changes between 1989 and 2012. One should recognise if afforested area is not overestimated using such approach, as a result of modification of forest definition in Poland in 1991. Additional question concerns the forest lands included into cadastral system after 1990, but afforested or resulting from natural succession occurring before that time, which currently are reported as afforestation under article 3.3. of Kyoto Protocol.

Opis:
Forest is a concept difficult to define in legal language. In European Union Member States the concept refers to both, an area from 0.05 ha up to 2 ha as well as an area of tree crowns from 10% to 30%. Forest definition in Poland is significantly different from the forest definition included in the European Union legislation. The Forest Act introduces four criteria of considering a given land a forest: environmental criterion, spatial criterion, criterion of the use for forest production and criterion of a relation with forest management. For the purpose of proper interpretation of forest definition, the interpretation of the following criteria is of importance: the use of the land for the purposes of forest management and its use for forest production. It is necessary to amend the forest act in the scope of specifying the forest definition. The legislator should also solve the problem concerning the issue of types of forest crops, a type of forest stand that can be considered as forest. A new forest definition should include the issue of planting fast-growing trees, pines understood as a separate type of production forests and the issue of considering the land as forest area, when this land cannot be of use for forest management.
Определение понятия леса в юридическом языке вызывает трудности. В государствах-членах Европейского Союза учитывается как территорию площадью от 0,05 до 2 гектаров, так и поверхность крон деревьев от 10% до 30%. Дефиниция леса в Польше значительно отличается от дефиниции принятой в законодательстве ЕС. Закон «о лесах» вводит четыре критерия признанная данного участка лесом: природный, территориальный, назначения для лесного производства и связи с лесном хозяйством. Для правильной интерпретации дефиниции леса значение имеет интерпретация критериев использования участка в лесном хозяйстве и его назначения для лесного производства. Существует не- обходимость новеллизации закона «о лесах» в сфере совершенствования дефиниции леса. Законодатель должен решить вопросы касающиеся видов лесных выращивании и древостоя, которые могут быть признаны лесом. Новая дефиниция должна определять позицию плантации деревьев быстрого роста, хвойных как отдельного вида производственных лесов, а также предусматривать ситуацию признания участков лесом тогда, когда они не могут быть использованы для лесного хозяйства.

Opis:
In this paper, we present problems with the management of the forests acquired by the State Forests from the State Land Fund. This was particularly an issue in forest districts with a significant share of private forests, e.g. eastern part of Poland. The problem becomes more and more valid because of the latest amendment of the Forest Act in 2016. It gives the State Forests the right of the first purchase of private forests attributed to sale. They may receive forest stands that will generate specific economic problems related to care, conservation, felling maintenance, etc. These are mostly stands with typical features of private forests, resulting from abandoning economic operations, selective acquisition, as well as from the size, shape and neighbourhood of the plots. This study presents the characteristics of almost 2,000 tree stands acquired from the State Land Fund between 1992−2016 by the Siedlce Forest District (SFD), which is a part of the Regional Directorate of the State Forests in Warsaw. SFD has low forest cover (18%), a strong fragmentation of forest complexes and a very large share of private forests (over 75%). The analysis was based primarily on the descriptions of forest stands and the quantitative and qualitative characteristics, presenting at the same time the problems that SFD has with conducting rational forest management in acquired plots. The current status of the forests transferred from the State Land Fund was assessed as unsatisfactory. The main problems in local conditions are: (i) inadequate fixation in acquired parcels next to private forests (difficulty in locating treatments and custody over the State property), (ii) depleted tree stands, (iii) inadequate parcels (too narrow) and (iv) complications related to co−ownership of parts seized plots. The need to carry out joint−assembly works (mainly land consolidation) or to introduce land communities that would facilitate the management of these forests was demonstrated.

Opis:
The objective of the present researches was to analyze a content and distribution of lead (Pb) and nickel (Ni) in the proflles of variously utilized rendzinas and rusty soils (forest, arabie soils). The nwestigations were carried out in the Lublin Upland (rendzinas) and the Sandomierz Basin (rusty soils). Within each soil type, 10 profiles were sampled (5 profiles from arable and 5 from forest soils). Beside the basic properties, there was established a total Pb and Ni content in the concentrated acid mixture HNO3 and HCIO4 (1:1). The samples were also examined for the determination of lead and nickel soluble in 1 mol HCl - dm-3. The elements were determined using the AAS technique, FAAS method. A lead content in rendzina soils ranged between 21.0 and 54.5 mg o kg-1, whereas in rusty soils from 3 up to 32.0 mg o kg-1. Lead soluble in l mol hydrochloric acid accounted for 33.1-59.6 % in rendzinas, while in rusty soils - from 3.9 up to 59.4 %. A total Ni level in Rendzinas was found within 22.0 and 46.1 mg o kg-1, whereas in rusty soils 0.5-5.0 mg o kg-1. Hydrochloric acid-soluble forms of nickel constituted 11.4-34.0 % of its total content in rendzina soils while between O and 42.8 % in rusty soils. Bom, rendzinas and rusty soils displayed the highest lead content in the humus horizons and a steady quantity decrease with the depth. The changes observed in a nickel content were not so pronounced, but in majority of profiles a lower Ni content was shown in the parent material as compared with humus horizons. Land use has not affected significantly a content of both analyzed elements in the soil horizons under study.
Celem przeprowadzonych badań była analiza zawartości i rozmieszczenia ołowiu i niklu w profilach rędzin i gleb rdzawych różnie użytkowanych (las, pole uprawne). Badania przeprowadzono na Wyżynie Lubelskiej (rędziny) i w Kotlinie Sandomierskiej (gleby rdzawe). Z każdego typu gleb pobrano próbki z 10 profili (po 5 profili gleb uprawnych i po 5 profili gleb leśnych). Oprócz podstawowych właściwości oznaczono całkowitą zawartość ołowiu i niklu po mineralizacji gleby w mieszaninie stężonych kwasów HNO3 i HC1O4 (1:1). W pobranych próbkach oznaczono również formy ołowiu i niklu rozpuszczalne w 1 mol o dm-3 HCl. Pierwiastki te oznaczono techniką ASA metodą FAAS. Zawartość ołowiu w rędzinach zawierała się w przedziale 21,0-55,9 mg o kg-1, a w glebach rdzawych od 3 do 32,0 mg o kg-1. Ołów rozpuszczalny w 1-molowym kwasie solnym stanowił od 33,1 do 59,6 % \v rędzinach i od 3,9 do 59,4 % w glebach rdzawych. Całkowita zawartość niklu w rędzinach wahała się od 22,0 do 46,5 mg o kg-1, a w glebach rdzawych od 0,5-5,0 mg o kg-1. Formy niklu rozpuszczalne w kwasie solnym stanowiły w rędzinach od 11,4 do 34,0% całkowitej zawartości, a w glebach rdzawych od 0 do 42,8 %. Zarówno rędziny, jak i gleby rdzawe charakteryzowały się największą zawartością ołowiu w poziomach próchnicznych i jego ilości systematycznie zmniejszała się wraz z głębokością. Zmiany w zawartości niklu nie były tak jednoznaczne, chociaż w większości profili obserwowano mniejszą zawartość tego pierwiastka w skale macierzystej niż w poziomach próchnicznych. Sposób użytkowania nie miał istotnego wpływu na zawartość obu analizowanych pierwiastków w profilach badanych gleb.

Opis:
Obszary objęte zmianami antropogenicznymi charakteryzuje brak naturalnych ekosystemów i nie ma powrotu do ich pierwotnego stanu. Istnieje natomiast konieczność naturalizacji użytkowania środowiska, zwłaszcza na terenach zniekształconych – zdegradowanych i zagrożonych degradacją. Fitomelioracja krajobrazów antropogenicznie zmienionych może być skutecznie przeprowadzona wyłącznie na podstawie programów wynikających z wiedzy o potrzebach społecznoekonomicznych oraz warunkach przyrodniczych i możliwościach technicznych. Opracowanie takiego programu musi być koniecznie poprzedzone dogłębną analizą warunków naturalnych, ze szczególnym uwzględnieniem oceny stopnia degradacji i potencjalnych zagrożeń na danym obszarze. Zakłada się, że każda powierzchnia wolna od infrastruktury technicznej powinna oprócz funkcji ekonomicznych spełniać kilka funkcji ekologicznych. Rekultywacja terenów zdegradowanych przez przemysł, górnictwo, zanieczyszczenia przemysłowe i składowanie odpadów w kierunku leśnym - stanowi ważne zadanie, niestety realizowane w niezadowalającym stopniu.
No natural ecosystems can be found within the areas subject to anthropogenic changes. Neither there is any return to primeval ecosystems. While there is a need to naturalise the way of using the environment, in particular that in the areas degraded or threatened by degradation. The phytomelioration of landscapes anthropogenically changed may be effectively carried out solely on the basis of programmes resulting from the knowledge on socio-economic needs and natural and technical conditions. The development of such a programme shall necessarily be preceded by an indepth analysis of natural conditions with special emphasis on evaluating the extent of degradation and potential threats within a given area. It is assumed that any surface free from technical build-up shall have some ecological function in addition to its economic functions. Forest reclamation of grounds which are either non-effective as agricultural land or degraded by mining industry, industrial pollutionsand waste disposal - constitutes an important task, regretfully implemented to an unsatisfying degree.

Opis:
The calamity windstorm in November 2004 caused dramatic changes of land cover in the Tatra Mountains. The bora have destroyed then more than 12,000 ha of forest and principally affected the habitat structure in the Tatra National Park. The aim of this contribution is to quantify changes in forest fragmentation in 2000 and 2006. We present forest fragmentation maps related to the years 2000 and 2006. The CORINE Land Cover data layers CLC 2000 and CLC 2006 converted to raster format were used as the input data in the process of forest fragmentation assessment. Forest pixels were classified according to fragmentation indices measured within the surrounding landscape as the forest core, forest patch, forest edge, and perforated forest. Decrease of the compact forest areas (forest core) by about 9% was recorded. On the other side, increased percentage of disrupted forest areas was observed. Decrease of the area of the CLC forest classes (classes 311, 312 and 313) on land cover maps from 2000 and 2006 was connected with an increased number of transitional woodland/shrubs polygons (CLC class 324). These results suggest a temporary fragmentation with possible forest regeneration. On the other hand, forest destruction in the National Park facilitated the development of travel and tourism (new hotels, ski parks, etc.). An increased number of construction sites (CLC class 133) indicate that an urban sprawl associated with a permanent forest fragmentation can be also expected in the future.

Forestry forms a substantial part of the rural economy. Wood ad other forest products and their processing secure a number of jobs in rural areas increasing socio−economic stability and development. Apart from the economic aspects, forestry has a lot of non−market values. It is necessary to analyse potential economic and social benefits of forestry to rural areas and their development of both market and nonmarket values and to include those benefits in rural conceptions.

Opis:
Nearly 3.5 million hectares of forest were contaminated by radioactive effluents from the Chernobyl Nuclear Power Plant. Pinus sylvestris L. is the species most sensitive to radiation. Pine wood showed the lowest levels of potential 137Cs activity, while in assimilatory apparatus and bark such activity was highest. Among the non−wood products, mushrooms, berries, medicinal plants and venison that feature the highest ability to accumulate radioactive elements. Partial cuts ensure canopy closure of stands and reduce the vertical and horizontal radionucleide migration. Afforestation is one of the main land reclamation methods applied in contaminated areas. Mechanical planting with limited tending of plantations is used most often there. In cutting areas with a radioactivity level dangerous to carry out regeneration operations, natural regeneration is used exclusively.

The paper shows differences in morphological and anatomical features of the Scots pine (Pinus sylvestris L.) growing on former agricultural and forest lands. It was found that at the same age and in the same climatic conditions Scots pines from former agricultural land had larger stem dimensions and needle sizes as compared with the trees growing on forest land. These results lead to an interesting conclusion connected with future afforestation and reforestiation in the Krynki Forest District.

Opis:
The international community affirms the critical role of forests in climate change mitigation, which includes reducing emissions from degradation and deforestation, carbon stock conservation, sustainable forest management, and increasing carbon stocks in developing countries. It relates to land use and land cover changes. This study aims to review land use and land cover changes (LULC) in two decades, namely 2000-2010 and 2010-2020, and the impact on carbon stocks. Landsat satellite imagery in 2000, 2010, and 2020 are classified into six categories: built-up area, cropland, forest, water body, bareland, and grassland. This classification uses supervised classification. The accuracy kappa coefficient values obtained for the LULC 2000, LULC 2010, and LULC 2020 maps were 89.61%, 83.90%, and 87.10%, respectively. The most dominant systematic LULC change processes were forest degradation in 2000-2020; the transition of forest to cropland (349.20 ha), forest to bareland (171.19 ha), and forest to built-up area (661.68 ha). Loss of using the forest for other uses was followed by a decrease in carbon stock. There was a high decrease in carbon stock in the forest category (11,000 Mg C∙y-1). The results showed a significant change in land use and cover. The decline in the area occurred in the forest category, which decreased from year to year. Meanwhile, the built-up area increases every year. Carbon stocks also decrease from year to year, especially forests as the most significant carbon store, decreasing in the area.

Opis:
The paper presents the studies involving analysis of changes in shape of parcels of arable land under the influence of forest succession. The object of the research is the village Grębosze located in Świętokrzyskie voivodeship. The study material will cover all arable land existing in the studied village. The source of data were numerical registry maps from 1998 and 2013. The basic element of research, enabling comparison of changes in the efficiency of the production process are continuous parts of the parcels covered by one form of use. In the course of the output data processing and determination of the necessary technical parameters for the tested surface elements, the specialized tools and statistics were used. The studies were related to the evaluation of formation of these surface structures on the basis of their shape meter in the form of the so-called costs of cultivation. The obtained results make it possible to tell, to what extent the changes resulting from the consequences of the secondary forest succession influence the process of cultivation of neighbouring arable land.
W pracy przedstawione zostały badania obejmujące analizę zmian ukształtowania parcel na gruntach ornych pod wpływem sukcesji leśnej. Obiektem badań jest sołectwo Grębosze położone w województwie świętokrzyskim. Materiał badawczy obejmie wszystkie grunty orne występujące w badanej wsi. Źródłem danych były numeryczne mapy ewidencyjne z lat 1998 i 2013. Podstawowym elementem badań, umożliwiającym porównanie zmian efektywności procesu produkcyjnego są ciągłe części działek ewidencyjnych objęte jedną formą użytkowania. W procesie przetworzenia danych wyjściowych oraz określenia niezbędnych parametrów technicznych badanych elementów powierzchniowych zastosowano specjalistyczne narzędzia informatyczne i statystyczne. Szczegółowe badania dotyczą oceny ukształtowania wspomnianych struktur powierzchniowych na bazie miernika ich ukształtowania w postaci tzw. kosztów uprawowych. Uzyskany wynik umożliwia stwierdzenie, w jakim stopniu zmiany wynikające z następstw wtórnej sukcesji leśnej wpływają na proces uprawy sąsiednich gruntów ornych.
