Under the exercise of these various rights and the uncertainty of property conditions, the forest conditions naturally deteriorated continuously until the end of the 18th century; the virgin woods were culled of their wealth and then grew up to brush, as is usual in the United States.

Every forest ordinance began with complaints regarding the increasing forest devastation, and predicted a timber famine in view of the increasing population, increasing industry and commerce, and hence increased wood consumption. Especially along the water routes, which furnished the means of transportation, the available supplies were ruthlessly exploited. More serious enemies than the exploitation of the timber proved the pasturing of cattle, the removal of the litter, and above all, the fires.

Towards the end of the 16th century, ordinances against forest fires began to be enacted; yet, as late as 1778, the necessity of keeping the rides or fire lanes open in the forests of Eastern Prussia is justified by the statement that “otherwise the still constantly recurring fires could not be checked.” At another place it is stated that “not a single acre of forest could be found in the province that had not been burnt in former or later times,” and that “the people are still too much accustomed to the ruthless use of fires, so that no punishment can stop them.”

Other causes of devastation were the Thirty Years’ War, the wars of the 18th century, and the loss of interest in the forest by the peasants after the collapse of the Mark. These had often to steal what they needed, and their depredations were increased by the desire to revenge themselves on the landed proprietors for the oppressions to which they were subjected. The increase in game, which was fostered by the landed gentry, did much damage to the young growths, and the increase in the living expenses of the nobility who mostly abandoned country for town had to be met by increased exploitation.

By the end of the middle ages the reduction of forest area had proceeded so far that it was generally believed desirable to restrict the making of clearings to exceptional necessities, except in the northeastern parts and in the distant mountain districts.

Yet a growing population increased the need for farm land, and since intensive use of the existing farm area was not attempted until the end of the 18th century, the forest had to yield still further.
