forest management -- forest ecology -- silvicultural systems

Аннотация: Forest ecosystems fulfil a range of functions, including providing environmental and cultural services as well as the production of wood. The paradigm of forest management has shifted across the world from maintaining a sustained yield of forest products to sustained forest ecosystem management. This book discusses and proposes new silvicultural approaches for sustainable forest management.

Drylands -- land rehabilitation -- rainwater harvesting

Аннотация: Microcatchment water harvesting (MCWH) improved the survival and growth of planted trees on heavy soils in Eastern Kenya five to six years after planting. In the best method, the cross-tied furrow microcatchments, the main annual increments (MAI; based on the average biomass of living trees multiplied by tree density and survival) of the total and usable biomass in PROSOPIS JULIFLORA were 2787 and 1610 kg ha-1 a-1 respectively, when the initial tree density was 500 to 1667 trees per hegtare. Based on survival, the idigenous ACACIA HORRIDA, A. MELLIFERA and A. ZANZIBARICA were the most suitable species for planting using MCWH. When both survival and yield were considered, a local seed source of the introduced P.JULIFLORA was superior to all other species. The MAI in MCWH was at the best distinctly higher than that in natural vegetation (163-307 and 66-111 kg ha-1 a-1 for total and usable biomass respectively); this cannot satisfy the fuelwood demand of concentrated populations, such as towns or irrigation schemes. The density of seeds of woody species in the topsoil was 40.1 seeds m-2 in the ACACIA- COMMIPHORA bushland and 12.6 seeds m-2 in the zone between the bushland and the Tana riverine forest. Rehabilitation of woody vegetation using the soil seed bank alone proved difficult due to the lack of seeds of desirable species. The regeneration and dynamics of woody vegetation were also studied both in cleared and undisturbed bushland. A sub-type of ACACIA-COMMIPHORA bushland was identified as ACACIA REFICIENS bushland, in which the dominant COMMIPHORA species is C.CAMPESTRIS. Most of the woody species did not have even-aged populations but cohort structures that were skewed towards young individuals. The woody vegetation and the status of soil nutrients were estimated to recover in 15-20 years on Vertic Natrargid soils after total removal of above-ground vegetation

Аннотация: Forestry has been defined as a science, but it is a combination of many sciences such as botany, biology, physics, and mathematics. It has been defined also as an art (the application of these sciences). The sciences are fundamentals upon which the art is based. Forestry includes the study of these sciences and their application, which is the art. Forestry may be simply defined as the science and art of managing forests so that they yield continuously their maximum of wood products, values, and influences

Norway spruce -- provenance -- damage -- yield

Аннотация: In the late 1930's, IUFRO (International Union of Forest Research Organizations) made available good seed of Norway spruce for establishment of provenance trials in eastern North America. Although World War II prevented best use of this material, several provenance experiments were planted. This paper: (1) reviews briefly the results to date of these experiments, (2) mentions several difficulties in growing Norway spruce, and (3) indicates the potential productivity of Norway spruce in various regions

forest regeneration -- survey -- forest types

Аннотация: The renewability of the forest is an important factor affecting our long-term economy, as it provides the basis for the sustained or continious yield of forest products from land best suited to this crop. Success in forest management depends primarily on the establishmentn of adequate regeneration of disirable species as soon as possible after the mature forest is cut. Tis therefore important in preparing to implement a sustained-yield management policy to know how well this requirement is being met under present operating conditions, and it was with the oject of having a comprehensive statement on the situation in Ontario that the Research Council of Ontario requested Prof. Hosie to review and report on the regeneration surveys that had been undertaken by various government and industrial agebsies in this Province.

Аннотация: Thinning is an important feature of suatained-yield forestry. Its aim is generally to improve the status and development of the remaining stand by means of a reduction of the number of stems. Another aim may be supply a demand of wood which cannot be covered by clear fellings only.

Аннотация: The paper describes a modified intercept-per cent method of preparing yield tables, and shows that intercept-per cent varies with stand age as well as with site. The tables provide number of trees, basal area, average diameter and volume in cubic feet for the merchantable portion of a stand by ten-year age classes. Merchantable volume at 100 years is 2,200 cubic feet on site A, 1,923 cubic feet on site B, 1,523 cubic feet on site F and 1,289 cubic feet on site D.

    A method of estimating site quality of logged land in the Coastal Douglas Fir belt of British Columbia

Кл.слова (ненормированные):
diameter growth%site index

Аннотация: In recent years there have been many advances towards the practice of forestry in British Columbia. Among these have been attampts at regulating the annual cut in accordance with the principles of sustained yield. This has drawn attention to methods of assessing the growth potentialities of logged lands. This report gives a practical method for estimating the site-quality of logged land in terms of site index and of forest associations, either of which may be of value to the forester. More field data have gone into the preparation of a method for predicting forest associations than into the site-index method, and the former has a higher degree of success in prediction. Four site classes, however, have been predicted in terms of site index as compared to three forest associations. It should be stressed that this method of estimating site-quality, by means of stump diameter-growth measurements, is not an exact one, but merely serves as a rough guide toward the mapping of logged land.

    An analysis of measures of density in even-aged balsam fir and jack pine stands

Кл.слова (ненормированные):
thinning%growing stock%methods

Аннотация: The concept of stand density is fundamental in forestry. Investigations of problems of mensuration, growth and yield, and silviculture need to consider density as one of the main stand variables. Several methods of expressing density were defined and discussed in an earlier study (Vezina 1963a). This paper discusses the results obtained in testing some common methods of expressing stand density in relation to crown closure of both balsam fir (Abies balsamea (L.) Mill.) and jack pine (Pinus banksiana Lamb.). stands in Quebec. A more general objective was to discuss the development of the stand density concept: how it developed in the past and how one may expect it to develop in the future.

Аннотация: The book shows how modern cost accounting can be applied to the forest enterprise. It focuses attention on the analytical methods employed to measure and judges its success and seeks to combine forest management and the forest yield science in a novel fusion of long term, intermediate, and short term planning. Some practical examples outline how the forest holding can apply economic methods to opening of forest areas, production, and marketing. There are many references to published works to assist the reader.

Аннотация: The background of this study was the continuous depopulation of the Swedish countryside which has involved an increased number of closures of smallholdings and farms on inferior land. Surveys have shown that between 0.5 and one million hectares of land used for agricultural production may go out of use. At present each year sees the conversion of approx. 20,000 hectares of arable land into forest in Sweden. One can calculate that if approx. 0.5 million hectares of arable land is turned into productive forest land the value of the yield of Swedish forestry will increase by approx. ten per cent provided that such plantings yield the expected result
