Absorbing heavy industry in marginal areas. The prospects of petroleum development in northern Norway |
| |
| Abstract: | The vegetation of Norway varies along three main gradients: from south to north, from the lowlands to the mountains, and inland from the coast. The underlying criteria used in preparing the enclosed new map of the vegetational regions of Norway in the scale 1:1.5 mill, are discussed, especially with regard to Central Norway. On the major maps of the vegetational zones of the Nordic countries so far published, Norway has received different treatment. A new zonal map based on the abovementioned regional map is presented and discussed. A coastal section is distinguished in the far west of Norway, and on the regional map this section is subdivided into three separate altitudinal belts. The remaining part of Norway is split into regions on the detailed regional map or into zones on the zonal map, as follows: nemoral, present only in the far south of Norway; boreonemoral, which extends north to the Trondheimsfjord; southern boreal, as far north as Salten; middle boreal, from the Østlandet area northwards up the major valleys into Central Norway and northeastwards to Alta in North Norway; northern boreal, up to the altitudinal (climatic) forest limit; and finally the low, middle and high alpine regions in the mountains. The vegetational regions of Central Norway are thereafter described in more detail and contour maps (isohypses) presented for the upper limits of the regions. |
