The aim of the paper was to assess the role of forest litter and mineral soil layers (0-10 and 10-20 cm) as stocks of plant-available macronutrients intheforested zone of the Karkonosze Mountains National Park, an area of forest decline at the end of 20th century. Soil samples were collected in 529 monitoring sites arranged in a 200x300 m grid. Concentrations of plant-available nutrients were much higher in the organic layer (forest litter) than in mineral soil layers, but calculated pools of available nutrients in the organic layer contributed to a lesser extent to their total pools. Those pools of nutrients stored up in the upper forest zone (1 000-1 250 m a.s.l.) proved to be significantly larger than those in the lower forest zone (500-750 m a.s.l.).

Two year-old needles were collected from 57 individuals from the Tatra Mts. between Grześ and Wołowiec summits. The needles were analysed in respect to 16 morphological and anatomical traits. Data obtained were subject of multivariate statistical analyses. The most stable traits appear to be needle thickness/width ratio, needle thickness and width, and width of epidermal cells. The most variable traits include the distance between vascular bundles and Marcet's coefficient. Intrapopulational variation is low.
