At present the State owns, largely in the northern districts, somewhat over 4.8 million acres (28.5%); but of this hardly 2 million acres are productive, and of these productive acres half a million consists of encumbered commons from which the State receives hardly any income. The district commons or communal, and other public institute forests comprise around 7,800,000 acres (46%); but here again only 580,000 acres are productive. The balance then, or a full one-quarter is in private hands.
Export trade in wood had been very early carried on, and had been considerably developed in the 13th and 14th century. By the middle of the 17th century the coast forest of oak had been cut out by Dutch and English wood merchants who had obtained logging privileges under special treaties of 1217 and 1308, and by Hanseatic cities, especially Hamburg entering this market in the middle of the 16th century.
There are records which would make it appear that at least some of the now denuded coast was forested in olden times. The development of the iron industry increased the drain on these supplies, which forest fires, insects and excessive grazing prevented from recuperating.
As early as the middle of the 16th century we find attempts to arrest the devastation by regulating the export trade and supervising the sawmills, forbidding especially the erection of sawmills intended to work for export only.
In the 17th century, various commissions were appointed by Christian IV to make forest reconnaissances and elaborate rules for proper forest use. In 1683, Christian V issued a forest ordinance increasing the number of forest inspectors instituted by his predecessor, and giving in detail the rules governing forest use, many of which proved impractical.
In 1725, a commission, the socalled forest and sawmill commission, was appointed to organize a forest service. It functioned until 1739, when the first Generalforstamt was established and the first attempt at real forest management was made. This came into existence through the efforts of two famous German foresters, J. G. von Langen and von Zanthier, who with six assistants were called in from the Harz mountains (as also afterwards to Denmark and Sweden), during the years 1736 to 1740, to make a forest survey and organize a management. Descriptions and instructions were elaborated in German and the service was largely manned by German “wood foresters” (holzforsterne). The strictness of the department which had been organized after von Langen’s departure in 1739, made it, however, unpopular, and, in 1746, it was abolished, von Zanthier returning to his country, the sole survivor, the other assistants having succumbed to scurvy. The administration was again placed in the hands of a commission which continued till 1760.
Only the forests connected with mines remained under the administration as instituted, and those belonging to the copperworks of Roras continued under its forest inspectors until 1901.
In that year, 1760, another shortlived attempt to organize a forest administration was made, but the new organization did not fare any better and was superseded in 1771. Then followed an interim regimen, during which the general government and district officers were in charge.
The old orders under which forest use had been regulated remained mostly in force until in 1795 all the reasonable and the unreasonable obstructions to export were removed. The sawmill privileges, under which English lumbermen held large areas for long terms and devastated them without regard to the impractical regulations, were, however, not ended until 1860. The wood industries were then relieved entirely from restrictions, and forest destruction progressed even more rapidly with the increasing facilities for transportation.
