The planting of hardwoods seems to have been begun much later; the first reference to it coming from the cloister and city of Seligenstadt, which agreed in 1491 to reforest annually 20 to 30 acres with oak.
Natural regeneration by coppice was in quite general practice and proved satisfactory enough for fuelwood production. The system of coppice with standards was also frequently practised, the standards, 20 or 30 to the acre, being “reserved for the lord.”
In the timber forest, the unregulated selection system was continued generally through the period, although in 1454 we find in the Harz Mountains a transition to a seed tree management, a few seed trees or groups of seed trees being left on the otherwise cleared area, somewhat in the manner of the French méthode à tire et-aire. Toward the end of the 15th century we find here and there a distinction made between timber forest, where no firewood is to be cut, and “leaf forest” which is to serve the latter purpose, and is to be treated as coppice.
Toward the end of the period we find, however, various provisions which are unquestionably dictated by the fear of a scarcity of timber. The discovery that pasture prevents natural regeneration led to a prohibition of pasturing in the newly cut felling areas. In 1488, we find already a diameter limit of 12 inches—just as is being advocated in the United States now—as a basis for conservative exploitation, the city of Brunswick buying stumpage, and in the contract being limited to this diameter, and in addition obligated to leave 15 oaks or aspen per acre for seed trees.
Attempts at regulating the use of a given forest by division into felling areas are recorded in 1359, when the city forest of Erfurt, 286 acres, was divided into seven felling areas. It is questionable whether this referred to a coppice with short rotation or whether a selection forest with seven periodic areas is meant.
We see, then, that the first sporadic and, to be sure, crude beginnings of a forest management in Germany may be traced back to the 14th and 15th centuries; but it took at least 250 to 350 years before such management became general.
Outside of the information found scattered in forest ordinances, instructions and prescriptions of various kinds there is no forestry literature to be recorded from this period except one single book, published about the year 1300, by an Italian, Petrus de Crescentiis, which was translated into German. It was merely a scholastic compilation on agriculture and allied subjects, mostly cribbed from old Roman writers and without value for German conditions.
II. First Development of Forestry Methods.
(Period 1500 to 1800.)
The period following the middle ages marks the gradual changes from the feudal system to the modern State organizations and to considerable change of ownership conditions and forest treatment. Various causes which led to an increased development of industrial life were also instrumental in hastening the progress of forest destruction. At the same time, during this period the germs and embryonic beginnings of every branch of forestry, real forestry policy, forestry practice and forestry science are to be noted. By the end of this period, preparatory to more modern conditions, we find organized technical forest administrations, well developed methods of silviculture and systems of forest management.
