Opis:
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:
In Poland, the afforestation rate is slowing down from year to year. An analysis of the demographic structure of land owners suitable for afforestation may contribute to a better recognition of trends and needs in order to increase the effectiveness of National Programme for the Augmentation of Forest Cover implementation, and thus increase interest in RDP activities. The aim of the study was to verify whether interest in afforestation among farmers is the same across the country in different age groups. The data presented in the publication come from the resources of the Agency for Restructuring and Modernization of Agriculture (ARiMR). The data covered the years 2004–2018 and were sorted by: voivodships (16), age group of beneficiaries of subsidies (4 groups), year of submitting the application (15 years) and the number of applications submitted. Beneficiaries were divided into four age groups: up to 30 years old, 31–40 years old, 41–60 and older than 60 years. Interest in afforestation changed in the period after Poland’s accession to the European Union. In recent years, there has been a significant decrease in the number of applications for afforestation subsidies submitted. There are also significant differences between the voivodships in the number of applications submitted. Farmers from eastern and southern Poland are more active in submitting applications for afforestation, and will reduce the so-called Recovered Territories in the western, northern and north-eastern part of Poland. Most afforestation in the entire analysed period is carried out by farmers aged 41–60 years. In the initial period, more applications were submitted by farmers of age over 60 years. In recent years, however, young farmers, that is, up to 40 years, are more interested in afforestation, than other groups. To increase interest in afforestation, more support should be directed to young farmers who, as part of farm specialization, may receive additional incentives for afforestation of land that is less useful to them.

Opis:
The paper analyzes the spatial and temporal diversity of afforestation of non−forest land, with particular emphasis on land not being the property of the State Treasury, before joining the European Union and as part of subsequent stages of the Rural Development Program. Data from the databases of the Statistics Poland and from the Agency for Restructuring and Modernisation of Agriculture was used. Afforestation in the period 2001−2018 was carried out with varying intensity throughout the country and in individual years. This condition was largely influenced by availability of land for afforestation and the form of land ownership. The history of the individual regions is clearly visible as well. Private forests occupy the smallest area in the territories incorporated into Poland after World War II, also in part of the former Prussia region and in the area covered by so called the ‘Wisła’ Operation in south−eastern Poland. In turn, in Podlasie and Lubelszczyzna regions (eastern Poland), the share of private forests is significant. The biggest changes in the afforestation structure took place after the introduction of subsidies for their establishment and care, after Poland’s accession to the European Union. In the period 2004−2018, the scope and criteria for granting the subsidies changed. New categories, which were to encourage beneficiaries to use this form of support, appeared. In 2004−2007 part of the Rural Development Program the area of afforested land in relation to the number of beneficiaries or issued decisions was the largest, while in subsequent campaigns the afforestation area decreased, despite the increase in the level of subsidies. The most important reasons for reducing the interest in afforestation are: decreasing resources of land intended for afforestation, greater interest among farmers in competitive payments for agricultural land, complicated bureaucratic procedures related to afforestation. The paper also highlights the most important restrictions that inhibit afforestation. These include: exclusion from afforestation of land located in Natura 2000 areas, exclusion of grassland (meadows and pastures) from afforestation and limitation of the aid granted for afforestation to one farmer to an area not exceeding 20 ha in the entire Program period. Lifting these barriers can have a positive effect on the creation of new afforestation or improvement of existing ones.

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:
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:
This paper presents pedological research in Žutica forest in northern Croatia. The most common soil types found in this area belong to the hydromorphic class (Pseudogley, pseudo- gley-gley, eugley, fluvisol) except technogenic soils formed as a result of intensive oil exploitation. Some main chemical and physical characteristics of soils are given. For forest productivity the most productive combination of soils are hypogley and pseudogley-gleysol and minimal productivity is in heavy amphygleic soils. An increase of heavy metals occurs in flooded soils in Žutica from nearby agricultural land. A high concentration of active phosphorus,and nitrogen can verify the influence of field fertilisers on the forest. Levels of cadmium found in technogenic soils exceed the permitted concentration. A large amount of CaCO3 in relation to natural forest soils can be found in technogenic soils because of quick lime disposal after oil spills and also pH increase and a nutrition and humus decrease.

Opis:
The economic development of the country is very much dependent on the development of the transport infrastructure, which is one of the main priorities of the state policy included in the planning and development documents. Ensuring a efficiently functioning transport system, primarily the network of roads, involves the need to improve the technical characteristics of existing roads or to build new sections. With the linear nature of road investments, we deal with interference in significant areas that have direct and indirect effects. The aim of the study was to analyze the impact of investments realized for different categories of public roads on the area of land needed to be excluded from forest production. The structure and area of the land as well as the number of forest superintendents transferred areas were also analyzed. The study was conducted for forest areas managed by the State Forests National Forest Holding (SF NFH). Data on the area of the transferred forest land was obtained from SF NFH units and the General Directorate of National Roads and Motorways (GDDKiA). In the years 2012−2015, SF NFH units transferred the land into the management of GDDKiA 203 times with the total area of 617 ha. In the same period, the transfer of the land ownership to local government for voivodship, county and municipal roads took place in 388 cases and covered 556.6 ha. Since 2003 (i.e when special act on road investments came into force), the area of the transferred land amounted to 282.7 ha in Toruń, 78.6 ha in Gdańsk and 558.4 ha in Poznań regional directorates of the State Forests. There was a decrease in the area of the transferred lands depending on the category of public roads, while the highest number of events for municipal roads was observed. There is a great variability in the time, number and area of property transferred to public roads.

Opis:
In this study, land use/land cover (LULC) changes were identified in AngYai Village, Sikhottabong District, Vientiane Capital, Laos, from 2015 to 2020 using the Geographic Information System (GIS) and remote sensing (RS). Topographic maps and Google Earth Pro satellite imagery data were used with ArcGIS 10.8 software to map land use fluctuations. The study area was classified into the six main types of LULC (agricultural, builtup, forest, main roads, waste land, and water bodies) based on field research, geographical conditions, and RS data. The results indicated sizeable increases in the built-up, main roads, and especially waste land areas over the study period. The forest and agricultural land areas decreased during the study period, possibly due to increased urbanization rates, nomadic cultivation, and indiscriminate deforestation in the study area. The river area was affected by the construction of hydroelectric dams and by the climate, leading to the drying up of water sources and causing water body areas to decrease to some extent.

Opis:
Traditional forest management as coppicing and coppicing-with-standard are recently considered as beneficial for biodiversity in woodlands. Cessation of coppicing leads to changes in stand structure and often loss of biodiversity. In contemporary Polish forestry coppicing is not applied, however some stands of coppice origin persist in Silesia until present. The overgrown coppice oak forests that cover the southern slopes at the foothills of the Sudetes Mountains (Silesia, Central Europe) are considered to be Euro-Siberian steppic woods with a Quercus sp. habitat (91I0): a priority habitat in the European Union, according to the Natura 2000 system. They support one of the largest populations of wild service tree (Sorbus torminalis Crantz) in Poland. In this study we investigated the relation of stand structure and trees parameters with environmental variables. The results showed considerable variability of stand volume, tree density and stems’ size correlated mostly with soil texture, but not nutrient content. We attributed it to soil dryness which seems to be the crucial factor controlling growth of trees. The natural regeneration of trees concentrated mostly on non-exposed sites on less acidic soils, but seedlings of wild service tree were present almost exclusively on most insolated sites, with shallow acidic soils. However, the regeneration of trees in sapling stage was restrained by browsing. Results suggest that maintaining of Sorbus torminalis requires protection against browsing, and some kind of active management is necessary to retain the observed stand structure with high proportion of wild service trees in stands on more fertile soils.

Opis:
The purpose of the article is to indicate and assess the impact of the legal regulations specifying the rights and obligations of the owner of agricultural land with trees and forest land included in the farm in the context of the activity conducted on that farm and environmental protection. The issues in question are wide, therefore the article focuses primarily on the afforestation of agricultural lands. It presents the evolution of legal regulations and the rights and obligations of agricultural producers who have afforested, including the maintenance of forests. The paper refers also to the law on the protection of agricultural and forest lands. Additionally, the paper discusses the permission to remove trees from the farmland and selected regulations concerning the subject of trees in the farms in the civil code and tax laws. In the conclusions the author states that the legislator tries to support, on the one hand, the protection of the environment (e.g. enlarging the forest area, quantitative and qualitative protection of forest land) and, on the other hand, the activity of an agricultural producer in this area by means of financial instruments (financial means related to afforestation of agricultural land, tax exemptions, compensation for obligatory afforestation or shrub planting).

Opis:
Extension of the forest area in Ukraine is one of the indicators confirming achievement of the goals of sustainable development. Therefore, the issue of protection, restoration and rational use of forest ecosystems is rather actual. The process of self- afforestation taking place on agricultural land, which are not used according to their intention because of their investment unattractiveness, due to lack of funds or other reasons, and thus, they are self-sown with forest plants, is one of the ways of the forest- covered area extension in Ukraine. There is no reliable information on the number of land plots with self-sown forests on agricultural land. Therefore, it is expedient to make inventory of them by using the tools of satellite remote sensing and field surveys. The author of the work suggests a conceptual model of planning the use of agricultural land with self-sown forests on the base of the inventory data. To make the best-possible decisions on the use of the land plots with self-sown forests, at the local level it is important to determine the rational direction of the self-sown forest use in the process of spatial planning on the base of the data of analysis of the soil and plant cover layer quality. Therefore, it is recommended to make zoning of the land by the kinds of land use (agricultural, forestry, recreational, nature protection). Basing on the zoning data and considering the potential ecosystem benefits from forests, it is necessary to develop measures on the self-sown forest use and protection.

Opis:
Young forest plantation established on abandoned agricultural land were compared to spontaneously developing young forest in order to evaluate their impact on biological activity of the soil. The study area was planted by pine trees in number 7 thous. per hectare. Aditionally, phytoameliorative tree species were planted singly on these plots in the following number: 1,5 thous., 3 thous. and 5 thous. per hectare. Some plots were pine monoculture.The following variant of site preparation prior to afforestation were used: agricultural ploughing (deep to 25 cm), agricultural ploughing with countersinking, deep ploughing (to 40−50 cm) and countersinking with ridges. All applied site preparation technics have detrimental effect on soil mesofauna. Collembola communities of five−year pine plantations are impoverished form of open area fauna. Phytoameliorative tree species do not accelerate soil fauna developement during the first years of secondary forest succession. Developement of soil fauna on abandoned agricultural land has been noticeably promoted by spontaneous succession of forest ecosystem.

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:
Struktura rolno-leśnej przestrzeni w Polsce jest wadliwa, zwłaszcza w środkowo-wschodniej części Polski. Przejawia się to najbardziej na tle jakości struktury przestrzennej pokrywy glebowej. Najsłabsze gleby piaskowe tworzą siedliska leśne, a w rolniczym użytkowaniu przeobrażają się łatwo w ruchome piaski, z wydmami włącznie. Na podstawie wskaźników waloryzacji rolniczej przestrzeni produkcyjnej powierzchnie gleb żytnich bardzo słabych i słabych (nieefektywnych gruntów rolnych) oraz lesistości wyliczono wskaźniki niedoboru lasu i lesistości optymalnej oraz opracowano i opublikowano mapę w skali 1: 1 000 000 „Polska potrzeby dolesień” według gmin w roku 1980. W roku 2016 na podstawie danych z ewidencji gruntów, opracowano mapę lesistości aktualnej, w celu porównania jej z lesistością optymalną w roku 1980. Ze względu na objętość danych liczbowych, analizie porównawczej poddano część gmin w województwach: 1) mazowieckim i łódzkim o bardzo dużym niedoborze lasu, 2) kieleckim o względnym niedoborze lasu, 3) lubuskim i pomorskim o bardzo dużej lesistości, 4) warmińsko-mazurskim o dużej lesistości. Przedstawiono strukturę przestrzenną wzrostu lesistości w latach 1980–2016 w znacznej części gmin na terenie 6 województw. Stwierdzono, że mimo realizacji krajowych programów zwiększenia lesistości w latach 1980–2016 obszary o bardzo dużym niedoborze lasów, tylko w nieznacznym stopniu pomniejszyły niedobór. Natomiast obszary o lesistości optymalnej wydatnie zwiększyły ich rozmiar.
The structure of agro-forest space in Poland is faulty, especially in the central-eastern part of Poland. This is most evident when compared to the quality of the spatial structure of the soil cover. The poorest sandy soils make up quite good forest habitats, whereas under agricultural use, they are easily transformed into moving sands, including sand dunes. On the basis of indices which valuate the agricultural production area – the areas of very weak and weak rye soils (inefficient agricultural land) – and forest cover – the indicators of forest cover deficiency and optimum forest cover – were calculated, and the map in the scale 1: 1 000 000 “Poland – needs for afforestation”, presenting the country divided into municipalities, was published in 1980. In 2016, based on the land registration data, a current forest cover map was compiled in order to compare it with the optimal forest cover in 1980. Owing to the volume of numerical data, a comparative analysis was performed for certain municipalities in the following voivodships: 1) Mazowieckie and Lodzkie with a considerable deficiency of woodland, 2) Kieleckie with a relative scarcity of forest cover, 3) Lubuskie and Pomorskie with a very extensive forest cover and Warmińsko-Mazurskie with an extensive forest cover. The spatial structure of the forest cover increase between the years 1980–2016 was presented in a large number of municipalities in six voivodeships. It was found that despite the implementation of national forest extension programs between the years 1980 and 2016, there was only slight a increase in forest cover in the areas with a very large forest deficiency. On the other hand, there was a significant increase in forest cover in the areas with an optimal forest cover.
