A Brief History of Forestry.

Not, however, until the revolutionary movements of 1848 and even later, was this divorce of the state idea from that of the person of the prince everywhere accomplished, nor was it carried through without many bickerings and quarrels between the princes and the representatives of the people, who claimed this domanium for the state. In the larger states, all this domanial property was finally declared state lands, while in the smaller principalities a partition of the land between the princes and the state took place, or else a relation was established by which a part of the revenue resulting from the state lands was secured to the princes.

An increase of the State’s property came also during the first decade of the century through the abolishment of cloisters and secularization of church property generally, the lands of both Protestant and Catholic church institutions being taken by the State.

Curiously enough, at the same time that the idea of state forest was being realized, the changes in economic thought which brought the principle of individualism to the fore gave rise to a movement to sell the state properties. This movement was inspired by French doctrines, whose influence was at the time very strong, by the teachings of Adam Smith who held that the state is not fit to conduct business, and by the hope that in private ownership an improvement in forest conditions would be more readily realized. These ideas by themselves would, probably, not have led to the adoption of a policy of sale if it had not been for the need for cash which, as a result of the French wars, was felt everywhere during the first years of the decade. The sale of this property seemed to provide a ready means for States to secure funds.

In Prussia, after the collapse of 1806, this measure was widely discussed, and eventually, in 1810 to 1813, repeatedly instructions for the sale of state forest property were issued. There were to be excluded from such sales only large complexes of forest, those on the sea coast, sand dunes and river fronts, where the protection of the forest cover was needed, and those which it was desirable to maintain for the use of important industrial establishments. Only the accession of Hartig (1811), as chief of the forest administration which was a branch of the Treasury department, prevented the execution of this dismemberment. It was due to him that the difference in character between farm and forest property began to be recognized. Although, after 1820, sales of forest property took place, they were never a fiscal measure, but were made either for the purpose of rounding off existing state forest property or paying off servitudes, or else in order to turn over agricultural soil to farm use. At present everywhere in Germany state properties are on the increase.

The property conditions of the communal forests naturally changed also with the political changes of the 19th century, when existing communities were made part of the large political machine and changed from economic and social to modern political municipalities. The ownership conditions, however, were not simplified, but as before, remained extremely varied.

Of the Mark forest but a very small portion remains to-day. The majority of it had been finally divided among the Märker in the first decade of the century, and the few remaining parts became independent of the political organization and now exist merely in the form of appurtenances to certain farm property known as Genossenwald (association forests). In addition to the variety of communal ownerships existing in the preceding period, some new communal properties originated from the granting of land in the settlement and dissolution of servitudes, whereby an undivided property (Interessentenwald) in which sometimes even the state retains an interest, came into existence.

The municipal property of the cities had become either the property of the entire community or of that part which constituted the real citizenship, or at least of a certain class of citizens of the municipality.

The incumbrances which had grown up with regard to forest property under the name of servitudes and which so much retarded the development of better forest management continued into this period, and although through the influences of the French revolution a desire had been stimulated to get rid of all curtailments of property, some have persisted to this day. Indeed, for a time an increase of these servitudes took place, due to the carelessness of forest officials in keeping unjustified use of the forest in check, when ancient usage of these rights of user was claimed and new servitudes were established.

In Bavaria, it became at last necessary (1852) to positively forbid the further establishment of new servitudes or rights of user. Laws having in view the dissolution or buying out of these rights were issued in Bavaria in 1805, and in Prussia in 1821, giving the right to forest owners whose properties were so encumbered, to call for a division of interests; but as at first the only way to settlement was by exchange for definite parcels of forest property, the progress in the abolishment of these rights was slow, until money exchange was permitted (as in Saxony, 1832). At the present time, the state forest administrations have mostly got rid of these servitudes, or at least have progressed so far in their regulation that they are now rarely impediments to forest management. These peaceable adjustments of the rights of user constitute the last act of freeing property socially and economically.

2. Forest Conditions

In spite of the sporadic efforts which had been made to bring about the recuperation of forest areas during the 18th century, the conditions of the forest at the beginning of the new century were most pitiable; the division of the Mark, by which the peasants became individual owners, profited little, and led to devastation rather than to improving the condition of the property. In addition, export trade in wood had become brisk, and the financial depression, a result of the French wars, led to increased exploitations, which, with the improvement in means of transportation, progressed to the more distant forest areas, and enlarged the waste area. Especially in the more densely populated parts of the country, the deforested area widened, and large wastes with poor young growth increased in all directions, in the same manner as now in the United States. The alarmists had good cause for renewing their cries, and, around the year 1800, a considerable literature sprung up on the subject of the threatened timber famine.

It is interesting to note that at that time the Catalpa played a role, at least on paper, as it does in our own day, being recommended as the only means of staving off the timber famine. A renewed betulomania spread widely over the country. In North Germany especially, great efforts were made to replant the denuded areas and to change the coppice areas, fit only for firewood, to coniferous species, pine, etc., by which eventually a great change in the forest type from the original mixed forest to the pure forest was effected.

3. Personnel

The great change which led to improved conditions, during the first half of the century, was pre-eminently due to the knowledge and intelligence of a group of men, six in number, competent foresters, who combined the high grade education of the Cameralists with the practitioners’ knowledge: Hartig, Cotta, Hundeshagen, Koenig, Pfeil and Heyer. These men built, to be sure, on the shoulders of their precursors of the century in which they were born, but, being placed in authoritative positions, found better opportunities for putting their teachings into practice.

The first two mentioned were older than the rest, and are usually described as the “fathers of modern forestry.” Born about a year apart, both educated at universities, they excelled in both scientific and practical directions.

Georg Ludwig Hartig (1764-1837), studied at the University of Giessen and, after having served in various functions in various parts of Southern Germany, became, in 1811, head of the Prussian forest administration. He was equally eminent as a practical man and organizer, as a writer, and as a teacher. In literary direction his work lay not so much in developing new ideas as in formulating clearly the known ones, as evidenced in his celebrated “General Rules” in silviculture.

Not less than thirty separate publications attest his assiduity. Among them stands pre-eminent “Anweisung zur Holzzucht für Foerster” (1791; 8th edition, 1818). As a teacher he began his work by establishing a masterschool (1789-1791) at Hungen, transferred to Stuttgart in 1807; and afterwards, as head of the Prussian forest administration, he lectured at the University of Berlin, continuing his lectures there, even after the forestry school at Eberswalde had been established, until his death.

He may be considered as having established on a firm basis the forest administration of Prussia; and many of the things he instituted still prevail. In organizing the service, he introduced fixed salaries, he relieved the foresters from financial responsibilities, transferring all handling of money to a separate set of officials, whereby the temptation to fraudulent practice of graft was removed, and he issued instructions for the different grades of foresters; and every part of this work was all his own. In regulating the forest area of the state he developed the volume allotment method, which, however, proved too cumbersome to be readily applied to large areas. Toward the end of his life, his work was not entirely successful, and he lost prestige in his later years.

Heinrich von Cotta (1763-1844) studied at the University of Jena, and afterwards practiced in Thuringia, where he established a master school at Zillbach (1795). In 1811, he was called to Saxony, as director of forest surveys, whither he also transferred his school, at Tharandt, which in 1816 was made a state institution and is still flourishing. In that year he was made the director of the Bureau of Forest Management. Like Hartig, he was eminent in the three directions of practical, literary, and educational work, but he excelled Hartig in originality, developing new principles and thought. Being a good plant-physiologist and observer of nature, he developed new ideas in silviculture, especially with reference to methods of thinning, and his “Anweisung zum Waldbau,” written in the simplest, clearest and most forceful manner, forms a classic worthy of study to this day. In the field of forest management he became the inventor of the area allotment method and the originator of the highly developed Saxon forest management. As a teacher he excelled in clearness, exposition, wealth of ideas and geniality.

Of an entirely different stamp was the third of the great masters, Johann Christian Hundeshagen (1783-1834), who having studied in Heidelberg, became after some years of practice, professor of forestry at Tuebingen, in 1817, and at Giessen, 1825. He was a representative of the theoretical or philosophical side of forestry, being highly cultivated and imbued with the spirit of science. His bent was to systematize the knowledge in existence and extend it by means of exact experiments. In forest organization, he invented the well known formula method or “rational method” of regulating felling budgets and became also one of the founders of Forest Statics (1826) which he called “the doctrine of measuring forestal forces,” being thus the forerunner of modern scientific forestry.

The fourth of the group, Gottlob König (1776-1849), was a practitioner without a university education, who had enjoyed the teaching and influence of Cotta whom he succeeded in Eisenach as the head of the ducal forest administration. He also founded here a private forest school, which, in 1830, became a state institution, and is still in existence. König became noted by his contributions to the scientific, especially the mathematical side of forestry, developing forest mensuration and statics. In this latter branch he was the forerunner of Pressler and of the modern school of finance. In his “Anleitung zur Holztaxation” (1813) he gives a complete account of forest mensuration and in the part devoted to forest valuation he develops the first soil rent formula and the methods of determining the cost value of stands. His “Forest Mathematics” (1835) in which he introduces factors of form and many other new ideas was an original contribution to science.

Very different in character from these four leaders was the aggressive, sharp-witted Friedrich Wilhelm Leopold Pfeil (1783-1859), who, without a university education, and in spite of his poor knowledge of mathematics and natural history, advanced himself by native wit and genius. After a brief period of employment in private service, in the province of Silesia, he accepted the position of professor of forestry at the Berlin University, in 1821, in connection with Hartig, with whom, however, he was at sword’s point. It was at his instigation, with the assistance of von Humboldt, that the school was transferred, in 1830, to Eberswalde, Pfeil becoming its director.

While Hartig was a generalizer, Pfeil was an individualizer, free from dogma, and most suggestive; a free lance and a fighter. Critical in the extreme and prolific in his literary work, he domineered the forestry literature of the day by means of his Kritische Blaetter, a journal of much import and merit.

The youngest of the group, Karl Heyer (1797-1856), a thoroughly educated man, combined the professorial position in the University of Giessen (1835) with practical management of a forest district, but in 1834 abandoned the latter in order to devote himself entirely to literary work. He was one of the clearest and most systematic expounders, and both his Waldbau (silviculture, 1854) and his Waldertragsregelung (forest organization, 1841) are classics. The last, fifth edition of the Waldbau, appearing in 1906 in two volumes, has been brought up to date by Professor Hess. He devised one of the most rational methods of forest organization, and, imbued with the necessity of basing forest management on exact scientific inquiry, instead of on empiricism alone, he formulated instructions for forest static investigations, a subject which his son, Gustav Heyer, elaborated into a science.

4. Progress in Silviculture

Natural regeneration continued to be the favorite method well into this period, and, for a long time, selection forest and coppice were all that was known in practice until Hartig and Cotta forced recognition of the shelterwood system.

The only way in which a transition from the generally practiced, unregulated selection forest to an intensive management was possible, with the ignorant personnel of underforesters, was to formulate into an easily intelligible prescription the necessary rules, allowing the least play to individual judgment. This was done by Hartig when he formulated his eight “General Rules” (1808) which coincided also closely with the teachings of Cotta. Since these rules represent in brief and most definitely the status of silvicultural knowledge on natural regeneration at the time, it may be desirable to translate them verbatim.

(1) “Every forest tree which is expected to propagate itself by natural regeneration must be old enough to bear good seed.

(2) “Every district or stand which is to be replaced by a thoroughly perfect stand by means of natural regeneration, must be brought into such position (density) that the soil may everywhere receive sufficient seeding.

(3) “Each compartment must be kept in such condition (density) that it cannot, before the seeding takes place, grow up to grass and weeds.

(4) “With species whose seed loses its power of germination through frost, as is the case with the oak and beech, the compartments must be given such a position (density) that the foliage which after the fall of seed covers and protects the same cannot be carried away by wind.

(5) “All stands must be given such density that the germinating plants in the same, as long as they are still tender, find sufficient protection from their mother trees against heat of the sun and against cold.

(6) “So soon as the young stand resulting from natural regeneration does not any longer require this motherly protection, it must gradually, through the careful removal of the mother trees, be accustomed to the weather, and finally must be entirely brought into the open position.

(7) “All the young growths, whether secured by natural or artificial seeding, must be freed from the accompanying less useful species and from weeds, if these in spite of all precaution threaten the better kinds.

(8) “From every young forest until it is full grown, the suppressed wood must be removed from time to time, so that the trees which are ahead or dominate may grow the better; the upper perfect crown cover, however, must not be interrupted until it is the intention to grow a new forest again in the place of the old one.”

Since these rules are applicable only in beech forests, much mischief and misconception resulted from their generalization; pure, even-aged high forests became the ideal, and the mixed forest, which was originally the most widespread condition, vanished to a large extent. This was especially unfortunate in Northern and Northeastern pine forests.

A reaction against Hartig’s generalization began about 1830, under the lead of Pfeil. He had at first agreed with Hartig, and then with equal narrowness advocated for many years a clear cutting system with artificial reforestation. Finally, however, he was not afraid to acknowledge that his early generalizations in this respect were a mistake, and that different conditions required different treatment.

In the development of the shelterwood system there was at first, under the lead of Hartig, a tendency to open up rather sharply, taking out about three-fourths of the existing stand, but gradually he became convinced that this was too much, and finally reduced the first removal to only about one-third of the stand. This was the origin of his nickname of Dunkelman. In spite of the fact that it was claimed that Cotta took the opposite view (for which he was called Lichtman), he, too, grew to favor a dark position, and, as he progressed, leaned more and more towards more careful opening up. Hartig originally recognized only three different fellings: the cutting for seed; the cutting for light; and the removal cutting. By and by, a second cut was made during the seed year, and the number of fellings to secure gradual removal were increased, so that, by 1801, this system seems to have been pretty nearly perfected to its modern conditions. The best exposition of this Femelschlagbetrieb (shelterwood system), as then developed, is to be found in Karl Heyer’s Handbook, 1854.

The method was unfortunately extended by Burgsdorf (1787) to the Northern pineries with a seventy year period of rotation. Within ten years, however, he recognized its inappropriateness, and modified it by instructions to leave only six to twelve seed trees per acre. His successor, Kropff, reduced the number of seed trees to four or five, which were to be removed within two or three years. In spite of the development of this more rational method, the practitioners under Hartig’s approval, held mainly to a dark position even for pine, much in the manner of a selection forest, which produced a poor growth of oppressed seedlings, retarding for a long time the development of the pineries.

In spruce or fir, either a pure selection forest or a strip system was employed. Attempts at a shelterwood system were made, but experience with the wind danger soon taught the lesson that this was not a proper method with shallow-rooted species. Even Hartig preferred for spruce clearing and planting, and this is still the most favored method with that species. For the deep-rooted and shade-enduring fir the shelterwood method with a long regeneration period was thoroughly established in the Black Forest, and in Württemberg by 1818.

Natural regeneration being the main method of reproduction until the beginning of the 19th century, artificial means, as is evident from the forest ordinances of Prussia and Bavaria (1812 and 1814), were usually applied only to repair fail-places, or to plant up wastes. In this artificial reforestation, with the exception of the planting of oak in pastures, sowing was almost entirely resorted to because it could be done cheaper and easier, but as the sowings were mostly made on unprepared soil and with very large amounts of seed (30 to 60 pounds per acre, now only 7 to 10 pounds), the results were not satisfactory, either because the seed did not find favorable conditions for germinating, or when germinated the stand was too dense.

Planting, if done at all, was done only with wildlings dug from the woods, and usually, following the practice of the planting of oak in pastures, with saplings: the plant material was too large for success. Nurseries, except for oak, were not known, even to Cotta in 1817; and Heyer, having to plant up several thousand acres, still relied on wildlings, two to three years old, which he took up with a ball of earth by means of his “hole spade,” a circular spade re-invented by him and much praised by others. Hartig, in 1833, still advised the use of four to five year old pine wildlings, root-pruned, but, eventually, having met with poor success, for which he was much discredited, came to the conclusion that un-pruned two-year-old plants were preferable.

The credit of having radically changed these practices belongs to Pfeil, who, entirely reversing his position, advocated for pine forest a system of clearing followed by sowing, or by planting of wildlings with a ball of earth. Then, suggesting that possibly planting without this precaution could be attempted, and pointing out the necessity of securing a satisfactory root system, he recommended, about 1830, the use of one-year-old seedlings grown in carefully prepared seed beds. While for securing these, he relied upon the simple preparation of the soil by spading, Biermans added the use of a fertilizer in the shape of the ashes of burned sod. The method of growing pine seedlings and planting them when one to three years old was further developed by Butlar (1845), who introduced the practice of dense sowing in the seed beds. He also invented an ingenious planting iron or dibble, a half cone of iron, which was thrown by the planter with great precision, first to make a hole and then to close it. This was improved by the addition of a long handle into the superior, well-known and much used Wartenberg planting dibble. At the same time (1840), Manteuffel devised the method known by his name of planting in mounds, which is especially applicable on wet soils.

It was not until 1840 that transplanting of yearling pines with naked roots became general. The widespread application of this latter system resulted in abandoning to a large extent mixed growth, and led to the establishment of pure pine forests, introducing thereby most intensively all the dangers incident to a clearing system and pure forest which are avoided by the mixed forest, namely, insects, frost and drought.

A practice of planting spruce in bunches, originally twelve to twenty plants in a bunch, had been in existence since 1780. This practice increased until 1850, and is still in use in the Harz mountains and in eastern Prussia, although the bunches have been reduced so as to contain only from three to five plants, the object of the bunching being to make sure that one or the other of the plants should live. Much discussion as to the merits of this method took place between the old masters, Cotta favoring the small bunches upon the basis of a successful plantation of his own, Hartig and Pfeil opposing it, but finally weakening. Since 1850, however, the practice of setting out single plants has become more general.

A reaction from the indiscriminate application of the shelterwood method to the hardwoods and of the clearing method to the pine set in during the last quarter of the 19th century under the lead of Burkhardt and Gayer. These advocated return to mixed forest and to natural regeneration with long periods, approaching a selection forest. Gayer especially, professor of silviculture at Munich, became the foremost apostle of this school. Yet even to this day, the principles of silvicultural treatment under the many different conditions remain unsettled. On the whole however, with the financial question assiduously brought forward, the clearing system has made most progress, and the selection system has nearly vanished, being replaced by the group method and the shelterwood system.
