Opis:
Presence of plant species, associated with ancient forests (continuous existence >200 years) can be used for assessing woodland biodiversity. The aim of this study is to specify which plant species, included in the ancient forests plant species list, can indicate old woodlands in parks and what plant features are characteristic for certain habitat types. Richest in ancient forest plant species are those fragments of woodlands, which have existed continuously for at least 120 years, and their fragments suffered least from human pressure during that time, whereas recent woodlands are characterized by a small share of ancient forest indicator species and domination of nitrophilous species. Investigated plants usually propagate vegetatively, their seeds are of a small size and they have regularly, densely set leaves. Plants associated with ancient woodlands are good indicators of woodland continuity in parks so they can be used for age assessment in these areas. Accumulation of such plants can be a useful criterion in parks evaluation. Proposed idea of sustainable management of a park space, including selection of areas of a great ecological value, can be a chance to preserve woodland biodiversity.

Opis:
The study of foliage was carried out in two different forest ecosystems: Vaccinio uliginosi- Betuletum pubescentis and Empetro nigri-Pinetum in the Slovinski National Park in the period of 2002-2005. The largest volume of nitrogen and phosphorus in the litter of coniferous needles was found in early summer at the moment of maximum growth. An average concentration of nitrogen in examined needles was between 1.296% and 1.358% N in Vaccinio uliginosi-Betuletum pubescentis and from 1.010% to 1.118% N in Empetro nigri-Pinetum. The decrease of biogenes concentration in plant tissues was observed in the autumn months as a result of lower demand and recession of biogenes connected with storage of valuable elements in the fatter parts of the trees. In the fall season, a gradual recession of nutrients from the litter of coniferous needles was observed. In Vaccinio uliginosi-Betuletum pubescentis insignificant quantity of nitrogen recesses (average 5.6%) from the new and one year old litter of coniferous needles, including 47.2% N-NH4 and 78.6% N-NO3 and about 21.8% P, including 11.7% P-PO4. In Empetro nigri-Pinetum more intensive recession of biogenes was found from the litter of coniferous needles of common pine than in Vaccinio uliginosi-Betuletum pubescentis. On average 11.5% T-N is translocated, including 41.4% N-NH4 and 23.8% N-NO3 as well as 22.3% P, including 11.8% P-PO4.
Badania listowia prowadzono w dwóch rożnych ekosystemach leśnych: Vaccinio uliginosi- Betuletum pubescentis i Empetro nigri-Pinetum w Słowińskim Parku Narodowym w latach 2002-2005. Największe ilości azotu i fosforu w igliwiu stwierdzono wczesnym latem w czasie maksymalnego wzrostu. Średnia koncentracja azotu w badanym igliwiu mieściła się w przedziale od 1,296% do 1,358% N w Vaccinio uliginosi-Betuletum pubescentis oraz od 1,010% do 1,118% N w Empetro nigri-Pinetum. Obniżenie koncentracji biogenow w tkankach roślinnych obserwowano w miesiącach jesiennych jako wynik mniejszego zapotrzebowania na nie oraz wycofywania biogenów związanych z magazynowaniem cennych pierwiastków w grubszych częściach drzew. W okresie jesiennym zaobserwowano rownież stopniowe wycofywanie nutrientów z igliwia. W Vaccinio uliginosi-Betuletum pubescentis wycofywane są nieznaczne ilości azotu (średnio 5,6%) z igliwia nowego i jednorocznego, w tym 47,2% N-NH4 i 78,6% N-NO3 oraz około 21,8% P, w tym 11,7% P-PO4. W Empetro nigri- Pinetum stwierdzono silniejsze wycofywanie biogenów z igliwia sosny zwyczajnej niż w Vaccinio uliginosi-Betuletum pubescentis. Średnio retranslokacji ulega 11,5% T-N, w tym 41,4% N-NH4 i 23,8% N-NO3 oraz 22,3% P, w tym 11,8% P-PO4.

Opis:
The research aimed to make an inventory of the vascular flora of 11 parks and gardens of the Pomeranian Cistercian Trail, with particular emphasis on taxa attached to old deciduous forests. A total of 62 species were registered, recognised as indicators of old deciduous forests in Poland. The presence of species of this group was confirmed in all of the analysed objects, but their number varied from 7 to 50. The group of ancient woodland species includes forest species for which the light indicator values are lower than or equal to 4 (plants of shadowy places, with a relative light intensity). The group of indicator species also includes forest geophytes and forest myrmecochores, autochores and barochores, as well as woodland species that can tolerate stress, under the classification of ecological strategy types S, S/CSR, S/SC and S/SR.

Opis:
A numerical analysis of the phytosociological relevés from ancient and recent woodland on a mesic forest site in central Poland was carried out. Three groups of forest stands were recognised: planted with Pinus, recent and ancient oak-hornbeam Tilio-Carpinetum. The species of ancient woodland occurred mainly in ancient oak-hornbeam forest stands, however some ferns: Dryopteris carthusiana, D. dilatata and D. filix-mas, and an orchid species Epipactis helleborine, are to be found mainly or exclusively in recent forests. The occurrence of ancient forest species in recent woods may be putatively explained by long-distance wind dispersal or by the thriving in situ in unrecognised small wood patches. Twelve ancient woodland indicators (i.e. 36% of a total number found in the region under study) occur exclusively in ancient woodland. It underlines the role of passive species protection in the maintenance of the regional species diversity.

Opis:
W pracy przedstawiono wyniki badań przeprowadzonych w latach hydrologicznych 2002/2003 i 2007/2008 w zlewniach śródleśnych oczek wodnych nr 1, 3, 5 i 6, usytuowanych w leśnictwach Wielisławice i Laski na terenie Leśnego Zakładu Doświadczalnego Siemianice Uniwersytetu Przyrodniczego w Poznaniu (rys. 1). Lasy tych leśnictw leżą w zasięgu Niziny Południowo-Wielkopolskiej, na Wysoczyźnie Wieruszowskiej, będącej zdenudowaną równiną morenową przeciętą biegiem górnej Prosny [6]. Omawiane tereny leżą w zlewni Niesobu i Pomianki, które są lewobrzeżnymi dopływami Prosny. Przeważającym typem siedliskowym lasu, w zlewniach analizowanych oczek, jest las mieszany świeży (LMśw), który zajmuje około 95% powierzchni, a dominującym gatunkiem drzewostanu jest sosna w wieku około 95 lat. W omawianych zlewniach, w terenach położonych najbliżej badanych oczek, występują w przewadze gleby bielicowo-rdzawe, o uziarnieniu piasku gliniastego, z wkładkami utworów mocniejszych.
The paper presents the results of the research carried out in 2002/2003 and 2007/2008 hydrological years. Hydrological year 2002/2003 was a middledry year in terms of rainfall - 56 mm lower than multi-year, when the air temperature was 1,0°C lower than multi-year average air temperature. The second analyzed year, 2007/2008 was a dry year - the rainfall total was 103 mm lower than multi-year and the air temperature was 0,8°C lower than average. The research was carried out in catchments of ponds No. 1, 3, 5 and 6, lo-cated in Wielisławice and Laski forestries - area of Siemianice Experimental Forest Farm of Poznan University of Life Sciences. The forests of mentioned forestries are within range of Południowo-Wielkopolska Lowland, on Wysoczyzna Wieruszowska, which is differential morainic plain, cut with the river Prosna headwaters. Discussed areas are located in catchment of Niesob and Pomianka rivers, which are left-bank tributaries of Prosna river. Fresh mixed forest is predominating in analyzed ponds' catchments - it takes about 95% of the area, and pine in age of ab. 95 years is predominating species of the tree stand. In areas situated closest to the ponds in analyzed catchments, there is a predominance of proper podzol soils with grain size of loamy sand. The ponds, discussed in this paper, have features typical for water reservoirs, from which essential are: the presence of water table, the presence of clearly outlined recess of the area, presence of vegetation affiliated with wet areas. The ponds No. 1 and 6, which have gentle slope, are typical natural melt ponds, ponds no. 3 and 5 are the results of human activities, as evidence by their unnatural shapes. The ponds No. 1 and 3 have no outflow. The pond No. 5 situated at the foot of morainic slope - is intensively supplied by spring waters from adjacent areas and it has constant outflow. According to the information from the local residents, the pond no 5 used to be a fish pond, and pond no. 6 in XIX century used to have an outflow through the ditch - today there's only left 60 m long section. Drainage occurred only at high states, mostly during the spring thaws. Currently discussed pond does not have any drainage, which is mainly attributable to the incidence of lower water levels and silting of the ditch. Two wetlands having their own microcatchments, located in south-eastern and eastern part of the catchment, has an important role in the water management of pond's no 6 catchment. Results of the research confirm that in most of analyzed ponds meteorological conditions (precipitation and air temperature) had a significant impact on the change of the water level. The only exception was pond no. 5, where the changes of the water level were caused by intensive supply by the spring waters. Studies have also shown that an important element in the characteristics of forest ponds, in addition to their morphometric features, is the variability of water levels in these ponds. A key determinant of changes in water levels in analyzed ponds, was the course of meteorological conditions, as well as the nature and size. In the research period most variable were ponds no. 1 and 3, characterized by small size and outflow, and the smallest variability had pond no. 5, supplied by the spring waters. Basing on the results of research and analysis it was also found, that in ponds of small size and with no outflow, with the highest variability of water levels, water table may disappear completely. Disappearance of the water table falls in these ponds mostly during the summer half-years.

Opis:
Plant diaspore dispersal is a fundamental process affecting the development of forest vegetation and its natural regeneration, especially with regard to typical woodland species, which spread slowly and form short-term soil seed banks. Most of these species have poor seed dispersal mechanisms, which is the major cause of their very slow expansion. The following questions were asked: (i) is there a relationship between the age of a woodland and the presence of forest vascular plant species representing different seed dispersal types; (ii) how do the proportions change between species representing different seed dispersal types in relation to the age of woodland; (iii) what factors determine the presence of species representing a given seed dispersal type; (iv) which factors affect the presence and which ones influence the abundance of selected woodland species? A multiple regression models were developed based on data obtained from 144 woodland patches designated for the study. A probit regression analysis was performed for selected species exhibiting various seed dispersal models. Woodland plants of all seed dispersal types show a significant relationship with the age of woodland, starting from the strongest linkage: anemochores, myrmecochores, endozoochores, epizoochores, barochores, autochores. As the woodland ages, the proportion of forest myrmecochores and anemochores grows, whilst the proportion of autochores, epizoochores and endozoochores shrinks. Results obtained indicate that the direct proximity of ancient woodland has a major effect on the occurrence of more poorly dispersing plants in recent woodlands, such as myrmecochores and heavy anemochores.

The analysis of the composition of the Tawny Owl pellets collected at a study site (Stary Chinów, 51o37’N, 21o28’E) in the northern part of the Kozienice Forest in 2019-2021 documented 18 species of small mammals. They represented three orders: Soricomorpha (4), Chiroptera (3), and Rodentia (11). The community of small mammals in the study area was relatively rich. The most frequently noted species were: Sorex araneus, Clethrionomys glareolus, Microtus agrestis and Apodemus flavicollis. The populations of rodents of the family Gliridae (Muscardinus avellanarius, Glis glis) and Microtus agrestis living on the study site are relatively abundant as compared to other areas of central Poland.

Opis:
Japanese larch (Larix kaempferi Sarg.) is one of the most frequent exotic species in Polish woodlands. The basic object of research comprised 60 stands of the studied species, located mainly in the northern and western parts of Poland. The growth results for the studied species, evaluated on the basis of the average height (hg55), were compared with data describing the local climate and the stand location within the botanical and climatic zoning. The results confirm the opinion that the Japanese larch prefers a climate of maritime character and generally shows high degree of flexibility regarding its climatic requirements (very large differences between the growth conditions in the studied area and the country of origin). The dependence between the growth results and precipitation is however lower than expected. The most interesting results include the relatively clear connection between the height of the larch stands and the Degórski’s (1984) ‘floristic’ ‘K’ (continentality) index.

Opis:
Gmina Uniejów to obszar rolniczy – ponad 80% jej powierzchni stanowią użytki rolne, a lesistość wynosi obecnie 10,6%. Jest to teren ubogi w lasy, które na obszarze gminy są w znacznym stopniu rozdrobnione, a ich roślinność antropogenicznie zaburzona. Brakuje większych kompleksów leśnych. W latach 2021–2022 przeprowadzono inwentaryzację flory w 33 wybranych losowo wyspach leśnych, których powierzchnia była mniejsza niż 10 ha. Oceniono przyrodniczą wartość badanych obiektów, wykorzystując gatunki wskaźnikowe („rośliny starych lasów”). W badanych wyspach leśnych odnotowano 21 gatunków roślin typowych dla starych lasów. W najbogatszym florystycznie obiekcie stwierdzono 10 gatunków wskaźnikowych dla starych lasów, a w najuboższych tylko po dwa tego typu taksony. Wyspy leśne gminy Uniejów cechują się małą liczbą gatunków typowych dla starych lasów. W większości są to obiekty wtórne na gruntach użytkowanych w przeszłości rolniczo.
Uniejów agricultural landscapes dominate in the Uniejów municipality as farmland takes up more than 80% of the area, while woodland constitutes only 10.6% and is reduced to separate small wooded patches (islands) with anthropogenically impaired flora. No larger forest tracts survived there. In the years 2021–2022, the flora of 33 randomly chosen forest islands (less than 10 ha) was examined and listed, focusing particularly on species belonging to the group of “ancient woodland indicators”. Altogether 21 species of plants typical of old forests were identified in the area, out of which 10 species were found in the “richest” forest patch and only two in the poorest one. Generally, forest islands in the Uniejów municipality contain few species confined to old forests. The islands represent mostly recent secondary woods on the formerly agricultural land.

Opis:
Black alder, an N-fixing tree is considered to accelerate the availability of phosphorus in soils due to the increased production of phosphatase enzymes, which are responsible for the P release from the litter. Acid phosphatase activity plays a pivotal role in organic P mineralization in forest soils and in making P available to plants. In order to check whether Alnus glutinosa stimulates acid phosphomonoesterase (PHACID) activity, we compared enzyme activities, total P concentration (PTOT), plant-available P (PAVAIL), organic P (PORG) and inorganic P (PINORG), and organic matter content in 27 ancient and 27 post-agricultural alder woods (the latter ones representing different age classes: 11-20, 21-40 and 41-60 years) of soil samples taken from the litter and the mineral layers. Phosphomonoesterase activity, organic matter, PTOT, PINORG and PORG concentrations were significantly higher in ancient alder woods than in the soils of post-agricultural forests. Significant differences in the acid phosphatase activity, organic matter and PAVAIL concentration were noted between the litter and mineral layers within the same forest type. In recent stands the amount of organic matter and phosphatase activity increased significantly with the age of alder stands, although only in the mineral layer of their soils. Phosphomonoesterase activity, organic matter and PAVAIL content were higher in a litter layer and decreased significantly at a mineral depth of the soil. The acid phosphatase activity was significantly correlated with organic matter content in both ancient and recent stands. There was no significant relationship between PHACID activity and any P forms.

Opis:
Głównym celem artykułu jest przedstawienie struktury sieci obiektów dwóch nadleśnictw - Czarna Bałostocka i Supraśl. Charakterystyczna jest ona także dla pozostałych nadleśnictw z terenu Puszczy Knyszyńskiej, a wykrystalizowała się w okresie międzywojennym i w zdecydowanej większości stanowią ją pojedyncze zagrody funkcyjne. Sporadyczne próby tworzenia większych jednostek, między innymi z okresu tzw. typizacji, nie są kontynuowane. leśniczówka - najmniejsza jednostka struktury dalej pozostanie podstawowym jej elementem. Jednak w związku z rozwojem cywilizacyjnym i postępem technicznym, a przede wszystkim w zgodzie z rachunkiem ekonomicznym układ ten może w przyszłości ulec zmianie.
The main aim of this article is to present the structure of the forest staff settlement network of two forest districts – Czarna Białostocka and Supraśl. it is also characteristic for the other districts in the area of Knyszyńska Forest and crystallized in the interwar period, and there are single functional settlements mainly. Sporadic attempts to create larger units during the period of socalled typifications, were not continued. woodland cottage - the smallest unit of the structure will continue to be the main element. in connection with the development of civilization and technological progress and above all due to the economic calculation, the system may change in the future.

Opis:
Unmanned aerial systems are in many countries one of the most dynamically developing branches of technology. They have also been recognized and are being utilized by scientists who find remote sensing indispensable in their work. Today, it is increasingly common to find research teams utilizing so-called drones in field research. Unmanned systems are becoming ever more important for environment monitoring by, on the one hand, providing data from inaccessible or remote areas, and, on the other hand, reducing the human costs required by traditional large field teams while also increasing the efficiency of the work. This paper presents the possibility of utilizing UAVs for image data collection in woodland areas. Flights over Głuchów and an Arboretum were performed using two different UAVs (Mentor, AVI). The flights were made in 2010 in the middle of the growing season. Images were taken with Sigma DP2 digital cameras in four spectral channels: R (red), G (green), B (blue) and IR (infrared). Images were saved in 8-bit. The Głuchów forest complex is located in the Głuchów forest district, which forms a part of the Rogów forest division. From the administrative viewpoint, the forest division is located in the Łódzkie province, Skierniewicki Poviat. The Arboretum is a park with a collection of trees and shrubs from different regions of the world. The area is characterized by a high variability of species and trees of varying heights. It is located in the Łódzkie province, Skierniewicki Poviat.
