| A pinewood of 173 ha in the municipality of Arnhem was destroyed by fire on July 7, 1976. In the spring of 1978 and 1979 about 82 ha of this terrain was planted with broadleaves and conifers. As an experiment to increase the moisture retention capacity and to hinder the settlement of weeds, a layer of 10 cm of chipped tree bark was strewed. The chipped bark came from the Netherlands, Belgium, Germany and Scandinavia. During a floristic inventory of the terrain in the summer of 1979 more than 300 wild plant species were found, many of them rare or even unknown in the Netherlands. Almost all these species were found on the part covered with tree bark. Presumably the seeds of many species were introduced with the tree bark. It seems worthwhile to follow the... |

| In the Dutch “Wadden District”, a chain of islands, mainly constituted of dunes poor in lime, Osmunda regalis is only known from the island of Terschelling, which is the poorest in lime. There it is known since 1886 from a single locality along the bank of a ditch at the innermost dune border. The habitat and the vegetation of this locality have been analysed. They have slightly been influenced by adjacent wood plantations in 1951 and 1959—1960 ( Pinus nigra, Alnus glutinosa, Prunus serotina), which seem to have induced Osmunda to spread. The open habitat is more related to the corresponding atlantic Irish one than to the more sheltered and shady habitat in Southern atlantic and subatlantic Europe. Concerning nutrition level of the substrate, which is very... |
