Opis:
Swedish whitebeam (Sorbus intermedia (Ehrh.) Pers.) is a species with a very limited range. It occurs only in southern Scandinavia and along the Baltic coast, without the Gulf of Finland. Its southernmost natural localities are situated in northern Poland. They are few in number, grouped in two regions: near Kołobrzeg and the Gulf of Gdańsk. Currently, only three of them survive: vicinity of Sarbinowo as well as Kępa Redłowska and Przylądek Rożewski. In the Podtatrze region, S. intermedia has long been planted along roads, on green areas, in gardens and parks, among others in Zakopane. In the Tatras it did not appear, so it is a foreign species for this region. Currently, in the Tatra National Park there are several hundred fruiting specimens of this species growing. Most of them are part of a forty−year−old stand planted on the back of the Grzybowiec ridge. The aim of this research was to recognise the health status of S. intermedia. Phytopathological research was conducted in 2018 in the Tatra National Park. Leaves that were subject to analysis were decontaminated in 1% surfactant solution of sodium hypochlorite. Their fragments of about 0.5 cm were placed on Petri plates with PDA (Potato Dextrose Agar). The growing fungal colonies were consequently re−planted onto PDA slants for further culturing and taxonomic identification. The pathogens were identified basing on morphological features and with molecular tools. All S. intermedia in the Tatra National Park showed disease symptoms. Infected S. intermedia leaves were colonized by A. alternata, which fraction amounted to over 40%. The following dominant was B. exigua with over 30% share. F. avenaceum (close to 10%) and E. nigrum and D. macrostoma were also found. The S. intermedia population growing in the Tatra National Park is characterized by a poor condition, which may in the future affect the population of this plant in the Tatra Mts.

Opis:
Pinus × rhaetica is holoarctic species, which represents mixed morphological features from both P. uncinata and P. mugo. It is a typical species living in peat−bogs in highlands and it is endangered by drainage and the decline of its natural area. By now, the greatest population of peat−bog pine is living in the Wielkie Torfowisko Batorowskie peat−bog, but its health condition is alarming. In Poland P. × rhaetica is placed on the red list of plants and fungi as an endangered species, with a high risk of extinction in the wild. In order to preserve the genetic potential of the population, the national park has taken active protective measures, establishing a conservative nursery. The aim of this study was to determine the potential role of fungi growing on needles of peat−bog pine in health condition. The study was carried out in three conservative pine nurseries in the Góry Stołowe National Park (SW Poland). Needles and dead wood of peat−bog pine were collected in July 2016. Material was decontaminated in 1% surfactant solution of sodium hypochlorite. The next step was the liner of about 0.5 cm pieces of needles of 6 Petri dishes with solidified, acidified PDA medium (agar−potato glucose). The dominant microscopic fungi inhabiting needles are Lophodermium pinastri, isolated from all of the plots, and Truncatella hartigii, which was observed only on Wielkie Torfowisko Batorowskie peat−bog (tab. 1). A much greater diversity of species of fungi characterized that peat−bog (tab. 2).
