Effect of waterlogging on regeneration in the dwarf birch (Betula nana)
Abstract The aim of this study was to determine the effect of waterlogging on annual regeneration in the dwarf birch (Betula nana L.), and to determine which demographic factors are responsible for the absence of B. nana in the waterlogged parts of a peat-bog. Growth parameters and demographic data...

Growth parameters and demographic data were collected from 2001 to 2003 at four sites in the Linje peat bog in the Chełmno Lake District in northern Poland. Three of the sites represented waterlogged open bog communities. The fourth site served as the reference. The density of first-year ramets, annual shoot growth, and the proportion of flowering shoots was significantly lower at the waterlogged sites than at the reference site. No seedlings were found during the course of the study, even though flowering and fruit production took place at the reference site. The flowering shoots were mainly between nine and thirteen years old. Ramets in this age range were found only at the reference site due to high mortality in mature ramets at the waterlogged sites. Mean ramet height was significantly lower at the waterlogged sites than at the reference site, and was strongly correlated with mean ramet age. The distribution of B. nana in peat bogs is limited primarily by two demographic factors: the high mortality rate in older ramets, and the low rate of vegetative reproduction. Another contribution factor is that the proportion of older fertile ramets is low. The effects of fluctuations in the water table on distribution of B. nana are also discussed.
