Atlas of the Netherlands Flora: Extinct and very rare species (Atlas of the Netherlands Flora, 1)

There is an element of fascination which many people feel about geographical maps, because these maps allow fantasies about strange landscapes, other peoples, travels, even adventures. Distribution maps, depicting the area which a plant (or animal) species occupies, would appear to be less romantic, but they are equally able to exercise our imagination, or rather: to stimulate our scientific curiosity. Some distribution patterns are repeated time and time again, although rarely fully identical, and with their study comes the inescapable question: what is it that determines a plant's area of distribution? Almost immediately we find ourselves in the area of ecology, for it is the plant's demands of its environment (climate, soil) which determines where it will be able to grow and where not. However, that is not all there is to it, for species as well as landscapes have their history, and one needs to be informed about the climate and about the distribution of land and sea in the past, for instance, before one can understand present distributions. This aspect of change in space and time (historical plant geography) is possibly the most fascinating part of plant geography. However this atlas, covering a minuscule part of the world, is not meant to be primarily a book of historical plant geography. It is true that a dynamic aspect is very prominent, but this is on the smaller time-scale of man-made changes, which mostly led to impoverishments.
