Abstract | View details | Full text in PDF | Author Info

In the densely populated Central Europe, forestry has always had different functions than in Scandinavia or Canada. Today the increasing pressures on the environment and more numerous demands of the people have put emphasis on environmental management and the demands of recreation in forest management practiced in the area. This paper outlines the trends in the utilization of forests in Central Europe, and especially in the Federal Republic of Germany, due to these changing targets. The regulations concerning forestry in Baden-Würtenber, and the forest plan of the Bavarian state forests are used as an example to clarify the principals of forest management and planning.

The paper deals with the establishment and present situation of the national parks in USA. The aim of the establishment of national parks was, on the one hand, to preserve part of the natural environment, and on the other hand, to reserve areas suitable for recreation. In addition to the national parks, or rather within them, so-called wilderness areas have been established since 1964. In these areas even such measures as fire and insect control are avoided to the greatest extent possible. The use of the wilderness areas for recreation is restricted to foot and horse trails as well as watercourses, all motorized transportation being prohibited. Campgrounds are provided with only the most primitive comforts. So far only a few wilderness areas have been established in the national parks, but there are tens of suitable areas that have been reserved for this purpose.

Abstract | View details | Full text in PDF | Author Info

The Sinivuori Nature Park, located in the northeast part of the county of Häme in Southern Finland represents the rare fertile forest lands in the country, and belong partly to the so-called centre of herb‐rich forests of Häme. Sinivuori is one of the smallest nature reserves in Finland (64 ha). The detailed vegetation analysis was performed in 1969, supplemented by earlier and later observations. The area was divided into 69 one-hectare squares for the study of the flora and vegetation.

The most common rock in the park is mica schist. The pH of the soil is relatively high, in average 6.6. Thermal-time sum is 1,100–1,200. The vegetation differs to a large extent from the surrounding areas. 169 vascular plants were found in the area, some of which very rare in the area. The paper lists the plants and their abundance in the area, and the vegetation is described by the forest types. Distribution maps are presented for the species.

Abstract | View details | Full text in PDF | Author Info

The purpose of forestry has hitherto been seen mainly as economic conservation, i.e. the use and management of timber resources on a sustainable yield basis. Along with the rising standard of living, however, amenity values of the environment will become more appreciated, which means that forestry and forest industries will be concerned with conservation of immaterial resources of nature as well. Since inland lakes cover some 10% of the surface area of Finland, and forests occupy more than 70% of the land area, forests and lakes are essential constituents of the Finnish environment during both work and leisure.

The main task of the pulp and paper industry in conservation is the control of water pollution. Today some 10% of Finnish lakes are polluted. Pulp and paper industries contribute 75% of the total waste water load of the Finnish lakes. Increasing water pollution can be prevented by improved processing technology, waste water treatment, and economic use of industrial wastes. Thus, the waste water load of the lakes has not increased in the last 10 years, despite doubling of pulp and paper production. According to the prognoses, by the year 2000 the waste water load from pulp and paper industries will be reduced to one half or one fourth of the present level although the capacity will still be increasing.

In forest management more emphasis should be paid on the aesthetic and recreational values of forests. Along with increasing leisure the need for recreational areas is growing. Scenic and recreational aspects must be considered in the management of industrial forests, too. With wise management, high timber yield is compatible with the maintenance of an enjoyable environment. Good silviculture takes account of timber production, wildlife management and landscape architecture simultaneously. National forestry development programs must be based on the principle of the multiple use of forests.

Abstract | View details | Full text in PDF | Author Info

The 4.4 km2 sized area of Rokua is a sandy ridge situated in the transitional zone between Central and Northern Finland. It has been suggested to become a new national park due to its, in the area unique landscape and geological characteristics.

The vegetation of the area has been little studied. A vegetation analysis was performed in 1945, 1947 and 1949. Due to low nutrients in the sandy soil, the number of species is relatively low, including 236 vascular plants. The climate is continental. Lichen covering of soil in the Scots pine (Pinus sylvestris L.) dominated forests is mostly intact compared to the more northern areas, because grazing of reindeer has been little. Fellings have increased in the surrounding areas of the planned national park. The article includes a detailed description of vegetation and flora in the area.

The article is report of the Nature Park and National Park Committee appointed by the Government of Finland in 1950. It contains a proposal for establishment of new nature parks and natural parks on state-owned lands in Finland. The article also includes a draft of act and decree for establishment of the new nature parks and national parks.

In order to replace the nature reserves lost through the 1944 Armistice with new areas and to create a comprehensive network of nature and national parks, including Southern Finland, the committee proposes new protected areas. The proposal includes the following nature parks: Jussaari, Vaskijärvi, Vesijako, Sinivuori, Häädetkeidas, Salamajärvi, Ulvinsalo, Paljakka, Runkaus, Maltio, Sompio, and Kevo. National parks include Liesjärvi, Linnansaari, Petkeljärvi, Pyhähäkki, Rokua, Oulanka-Juuma, and Lemmenjoki. The total area of the suggested new 23 nature reserves is 1,425 km2. The committee suggets that the administration of the new nature parks and national parks should remain in the responsibility of Forest Service and Forest Research Institute.

Abstract | View details | Full text in PDF | Author Info

The article is based on the writer’s visits in the area in 1933 and 1939. Pyhätunturi national park was established in 1938. The fell of Pyhätunturi rises up to 540 meters above the sea level, and 357 meters above the surrounding area. The soil is predominantly stony, and the rock is quartzite. The climate is continental with low rainfall. This results in a barren area, where array of plant species is limited with the exception of few gorges with fertile river valleys. The forests have remained mostly in natural state.

Vegetation is arranged in three zones: forested area, subalpine fell birch area and alpine bare top of the fell. Scots pine (Pinus sylvestris L.) forms timberline more often than Norway spruce (Picea abies (L.) H. Karst.). Coniferous forests rise up to 365 meters on the northern slopes and up to about 385 on the southern slopes of the fell. It is followed by fell birch zone (Betula tortuosa, now Betula pubescens subsp. Czerepanovii) up to about 450-475 meters on the eastern and northern slopes, and 475-490 meters on the western slopes. The most common forest site type is Empetrum-Myrtillus site type. Herb-rich spruce swamps along the rivers have highest diversity of species. The article describes the plant species found in forests, peatlands, fell birch zone and top of the fell in detail. In all 162 different vascular plant species and 16 non-indigenous species were found in the area.

Abstract | View details | Full text in PDF | Author Info

Labour legislation has developed strongly in a short time, and ways of its application have not yet been established. The article defines first the concept of forest worker from the point of view of the labour law. Collective agreement, contract of employment, wages, work instructions, and labour disputes concerning forest work are discussed. Finally, the author discourses the issues associated to occupational safety and health legislation, for instance, working hours, accident insurance and forest accommodation.

Forest work is typically seasonal, and it is payed for time or piece rates or by the job. The collective agreements have been difficult to apply in forest work, and more important have been the contract of employment. Labour disputes have been rare. The reported accidents in forest and floating work have increased since the Law on Accident Insurance entered into force in 1925. Compared to many other sectors, forest work has high risk for accidents.

Metsähallitus (Forest Service) decided to protect two areas around Hiisijärvi lake in Eastern Finland already in 1916. Later, a natural park was suggested to be established in the area. A survey of the vegetation in the area was composed in 1931-1932. The total land area of the protected area was 3.5 km3. A vegetation map was drawn based on a nature inventory. A detailed description of the forest site types, peatland types, aquatic flora and the vegetation of the area are included in the article. The calcareous soil promotes rich vegetation. Typical for the area are also rich fens. The area can be divided to a eutrophic and a oligotrophic part.

The earliest local records of lack of timber in Finland are from the 1600th century when Finland belonged to Sweden. The causes vary from burning of tar and shifting cultivation to local factories using fuel wood. Best preserved were forests in Lapland and Kainuu in Northern Finland and those parts of Karelia where shifting cultivation was not practiced. Especially harmful was shifting cultivation, because it made it impossible to grow valuable timber. The state did not intervene in the use of forests until it itself began to need more wood. Shipbuilding was the first cause to limit the use of wood, especially need of mast trees of pine and oak. Also the use of timber by private sawmills began to raise general concern in the 16th century. They influenced the decrease of forests in the 1800th century, due to the limited wood procurement areas and selection felling of timber trees. The establishment of sawmills became regulated in 1700th century. Collective forest ownership by the farms was seen at the time one of the reasons to forest devastation. In 1654 the state of Sweden forbade the burning of mast or in timber forests. Mining industry needed much fuel wood, and shifting cultivation was forbidden near the mines in 1734. Regulations and instructions were also on given on use of wood, for instance, in building, in fences, leaf fodder, fuel wood and tar burning.

Despite of many efforts, the government of Sweden could not prevent devastation of forests in Finland. The many wars of the state hindered economic growth, the regulations were sporadic and often difficult to apply, there was little supervision, the understanding of forestry was poor, and the remote Finland was often neglected in Sweden.

Abstract | View details | Full text in PDF | Author Info

The article gives a proposal for areas that would be suitable for protected areas, situated in state-owned lands in Northern Finland. Eight areas are described in the article, namely Oulankajoki area in Northern Kuusamo, Kutsajoki area in Kuolajärvi, Pyhätunturi in Kemijärvi, Pisavaara in Rovaniemi, Pallastunturi and Ounastunturi area, Malla fells in Kilpisjärvi, Pääskyspahta area in Petsamo and Heinäsaari in Petsamo.

Each of the areas possess special features in Finnish nature, samples of which should be reserved in pristine state. Furthermore, costs of the protection are small. The resident population is, however, in general against protection. The protection should therefore be organized in a way that minimizes the disadvantages caused by limitations to land use, for example grazing, reindeer husbandry, fishing and hunting.

According to Finnish Nature Conservation Act, all wildlife in the conservation areas should be protected. Protection of wolverine and wolf is, however, difficult because of the damages they cause for domestic animals. Protection of bear is regarded to be possible in most of the proposed protected areas.

The Oulanka National Park is situated in the district of Kuusamo on the eastern border of Finland, close to the Arctic Circle and within the coniferous forest zone. It covers a surface area of 107 km2, and is known for the richness of its vegetation and flora, a product of a varied bedrock pattern including occurrences of dolomite. A description is given of the vegetation of the 9 forest and 47 peatland types distinguishable in the area by means of tables based on quadrat surveys. The distribution of each forest and peatland type is described in a vegetation map. The vegetation types are discussed in terms of the structure of their soil and the ecological and floristic features of their plant cover.
