The earliest manor parks, which are a special form of cultivated forests, were created at the end of the 18th century. The surrounding of the main buildings was divided into two parts, an aesthetic park and yard serving household and economic purposes. Early in the 19th century, large parks were created which represented dominant aesthetic ideals but, on the other hand, formed a ”wild” counterpart to the structured inner world of the main building. A good example is Ratula Manor and its park, which represent the diversity of the cultivated forest of the 19th century manors.
The paper is based on a lecture given in the seminar ‘The forest as a Finnish cultural entity’, held in Helsinki in 1986. The PDF includes a summary in English.

The study is the first report of a larger project concerning fire ecology in the Finnish boreal forests. Modern forestry has never been practiced in the Ulvinsalo strict nature reserve (2,500 ha) in Northern Finland in the county of Kuhmo. Forest fires have been uncommon because of mosaic of mineral and peat soils. The forests are mostly Norway spruce (Picea abies (L.) H. Karst.) dominated with Scots pine (Pinus sylvestris L.) often as the oldest trees of a stand. Forest fires were dated by counting annual rings from cambium to the fire scar in pines. 73 stands covering 1,207 ha were surveyed, over 80% of which was on mineral soil.
50% of the area had burned at least once during the life time of the present pine trees. 48 different forest fires were found, the first being from the year 1712 and the latest from 1969. The average time elapsed between the fires was about 82±43 years, and range 18–219 years. It was assumed that the stands where no fire scars were found, had, however, regenerated after fires but no fires have occurred since after that. In latter part of the 19th century 21 forest fires were dated, in the other half centuries only 4–9. This may have been caused by the increased human activity in the late 1800’s. The fire rotation of the area is 280 years, and spruce is almost the only tree species, which can regenerate in the present situation.

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.

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.

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.

A vegetation survey was conducted in the Pisavaara national park in Northern Finland in 1946 and 1947. The national park (49,9 km2) includes southern half of the Pisavaara hills. The rock is quartzite. The most common vegetation type is dry upland forest type, but also fresh mineral soil sites are typical for the area.
The most common forest type, Empetrum-Myrtillus type coveres almost as much of the area as all the other forest types combined. The article describes in detail the vegetation of all forest types and gives a complete list of all plant species found in the survey. Total of 291 vascular plants was found, 242 of which were native to the area. In addition, 49 anthropochores had spread to the area when the forest ranger’s cottage was built. Number of species growing in the northern edge of their natural range is. Southern species can be found in the southern slopes of the hill.

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.

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.
