“…This difference was most extreme for Juncaceae, which contributed close to 10% of the seed bank but only 0.1% of the vegetation cover. This is consistent with other studies (Chippindale & Milton 1934; Williams 1985; Bossuyt & Honnay 2008) and probably reflects the weedy strategies of most of these species, however not for Juncus squarrosus . The 15 species only found in the seed bank do not represent characteristic heathland species, but rather ruderals like Taraxacum vulgaris, Trifolium repens Plantago major and S. vulgaris , in addition to early successionals like Sagina procumbens, Juncus bufonuis, J. conglomoratus, J. effuses and J. filiformis , and seeders like Salix caprea, D. purpurea and V. chamaedrys .…”

Questions: How do species composition and abundance of soil seed bank and standing vegetation vary over the course of a post-fire succession in northern heathlands? What is the role of seed banks -do they act as a refuge for early successional species or can they simply be seen as a spillover from the extant local vegetation?Location: Coastal Calluna heathlands, Western Norway. Methods:We analysed vegetation and seed bank along a 24-year post-fire chronosequence. Patterns in community composition, similarity and abundances were tested using multivariate analyses, Srensen's index of similarity, vegetation cover (%) and seedling counts.Results: The total diversity of vegetation and seed bank were 60 and 54 vascular plant taxa, respectively, with 39 shared species, resulting in 68% similarity overall. Over 24 years, the heathland community progressed from open newly burned ground via species rich graminoid-and herb-dominated vegetation to mature Calluna heath. Post-fire succession was not reflected in the seed bank. The 10 most abundant species constituted 98% of the germinated seeds. The most abundant were Calluna vulgaris (49%; 12 018 seeds m À 2 ) and Erica tetralix (34%; 8 414 seeds m À 2 ). Calluna showed significantly higher germination the first 2 years following fire.Conclusions: Vegetation species richness, ranging from 23 to 46 species yr À 1 , showed a unimodal pattern over the post-fire succession. In contrast, the seed bank species richness, ranging from 21 to 31 species yr À 1 , showed no trend. This suggests that the seed bank act as a refuge; providing a constant source of recruits for species that colonise newly burned areas. The traditional management regime has not depleted or destroyed the seed banks and continued management is needed to ensure sustainability of northern heathlands.

“…Conversely, the highest number of species was observed on the limed treatment. The lower abundance of dicotyledons and of Festuca rubra on the fertilized treatment (Table 3) corroborates the observations of Williams (1985). The presence of a smaller number of plant species on the fertilized treatments conforms with the observations of Schellberg et al.…”

The effect of surface liming on herbage production in permanent grasslands is rather uncertain. To better understand the effect of liming on the grassland, a study was made with a field experiment and a pot experiment with soil from the same field. In the field, the effects of liming and NPK fertilization on the production and composition of the vegetation were studied. In pots, the effects of liming and phosphate fertilization on different grass species were analysed. The effect of NPK fertilization (+3AE96 t ha )1 ) on the production of the original grassland was greater than that of liming (+0AE68 t ha )1 ), which was only observed (P < 0AE05) on the unfertilized plots. Liming increased the total number of species and the proportion of dicotyledons. After replacing the semi-natural community with Dactylis glomerata L., the effects of liming (+2AE37 t ha )1 ) and fertilization (+6AE52 t ha )1 ) were increased. These results, together with those of the pot trial, show the important role of phosphorus in the fertilization effect, and are interpreted as a protective effect of P against aluminium toxicity.

“…Sorrel, Buttercup and Catsear) are sensitive to increased soil fertility and herbicide treatment (Peel et al 1985, Williams 1985 and have therefore declined on farmland (Grime et al 1989). Conversely, other food plants well suited to increased fertility, grazing and trampling, such as Chickweed, Docks and annual Meadow-Grass Poa annua, remain common and may even have increased in recent decades (Grime et al 1989, Whitehead & Wright 1989, Sotherton & Self 2000.…”
