Salix Lapponum

The aim of this study was to make an evaluation of the current stands of a relict species, <i>Salix lapponum</i>, within the area of the Polesie National Park, to determine the population size and condition of downy willow as well as to analyse biocenotic conditions in its stands. The study, conducted in the years 2001-2003, allowed to establish that the number of <i>S. lapponum</i> stands had decreased significantly and that its population size in the confirmed stands in the Polesie National Park was substantially lower than 50 years ago. <i>Salix lapponum</i> was a component of different phytocoenoses, but its highest population size and a high degree of development were noted at the sites with the <i>Betulo-Salicetum</i> repentis and <i>Thelypteridi-Phragmitetum</i> communities. The character of the phytocoenoses in which <i>Salix lapponum</i> occurred in greatest numbers may evidence the wide range of tolerance of downy willow with respect to habitat conditions. There is a probability that not only the changes in its habitat conditions, which were noted over the last half-century, had a significant effect on the reduction in the number of stands and in the population size of this species. An essential problem appears to be the fact of the absence of flowering in individuals in many of the studied populations, which may result in an insufficient degree of adaptation of <i>S. lapponum</i> to changing habitat conditions.

Salix Lapponum

The species of downy willow (<em>Salix lapponum</em>) and swamp willow (<em>Salix myrtilloides</em>) are extremely rare relicts among all members of the genus <em>Salix</em>. In Poland, they occur only in the eastern part of the Karkonosze Mountains, Masurian Lake District, and Polesie Lubelskie area. A huge threat to both species is the drainage of peat bogs and their excessive exploitation as well as diseases caused by bacteria and fungi. The present study aimed identify fungal species colonizing the aboveground organs of plants with disease symptoms and to indicate which species may pose a threat towards <em>S. lapponum</em> and <em>S. myrtilloides</em> growing under natural conditions. This research was conducted in Polesie National Park as a part of a research project by the Ministry of Science and Higher Education. Plant health assessments were carried out in natural habitats, while aboveground organs with disease symptoms were collected for laboratory mycological analysis. <em>Colletotrichum salicis</em> (teleomorph <em>Glomerella salicis</em>), <em>Coniothyrium concentricum</em>, <em>Cylindrosporium salicinum</em>, <em>Phomopsis</em> spp., <em>Truncatella angustata</em>, and <em>Cytospora chrysosperma</em> (teleomorph <em>Valsa sordida</em>) were the fungal species most frequently isolated from leaves and shoots of both willow species. The above-mentioned fungi are dangerous plant pathogens from the family Salicaceae. There were no obligatory parasites or monophagous pathogens on the aboveground organs of downy or swamp willow. Obligatory parasites may indicate a markedly low population of host plants in Polish conditions.
