    Opis:
    During the survey of the Mały Borek nature reserve (Augustów Forest, NE Poland) 236 species of vascular plants were recorded, including 10 plant species red-listed in Poland and 19 species protected under the Polish law. The most valuable species were sedges typical of the boreal coniferous forests: Carex vaginata, C. globularis and C. loliacea. The presence of neophytes was very limited (1,3% of the flora) in the area studied. The principal aim of the establishment of the reserve was the conservation of old-growth coniferous forests with long ecological continuity. Since the reserve studied consists mainly of old-growth coniferous forests, the number of species regarded as ancient forest indicators is lower (54 species) than in the well-preserved reserves with deciduous stands in north-east Poland, but still rather high. The most valuable, threatened species are bound to wetland forests that are presently disturbed due to drainage. Restoration of the former hydrological conditions is essential for the preservation of the vascular plants in the reserve.

    post-agricultural soil
    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:
    Mostly parks and forest are the most important ‘green islands’ in urban ecological network. Urban forests are belong to green areas and collected many plant species. The main aim of the article was characteristic of ancient plant species in urban forests in Tarnów. The field studies were carried out in years 2011–2012. It covered 80 phytosociological records on the area 500 m2 in herb layer of urban forests and in forest nature on oak-hornbeam. The results showed that many ancient plant species were growing in urban forest but less than in nature reserves.

    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:
    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:
    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.
