Abstract

Mixed stands are the most frequent type of stand in Nordic countries. A mixture of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) is the most common stand type in the region. But for most foresters and persons familiar with forestry, a mixed stand implies a conifer...

Abstract

Moose (Alces alces) browsing during winter in young (established in 1984) managed plantations of Scots pine (Pinus sylvestris) was assessed in relation to silvicultural cleanings. Field data were collected in central Finland during 1990-96. The study area was divided into 13 silviculturally cleaned ...

Abstract

The effects of moose (Alces alces) browsing on the early development of young Scots pine (Pinus sylvestris) were examined 2 years after planting at Lapinjärvi, southern Finland during 1993-94. Study plots comprised 3 pine density classes (<1300, 1300-2100 and >2100 pines/ha) and deciduous...

Abstract

[Cf. FA 37, 2597; 38, 4540] Data are tabulated and discussed from pulping, beating and washing experiments on pulps including various proportions of the bark and leaves of 4 species: Aspen (Populus tremula), Sallow (Salix caprea), White Birch [Betula pubescens] and Grey Alder (Alnus incana). Leaves ...

Abstract

Sulphate pulps from whole-tree leafless samples of 3- to 5-year-old, 10- to 15-year-old and 20- to 25-year-old Populus tremula, Alnus incana, Salix caprea and Betula pubescens, and 9-year-old Populus tremula X P. tremuloides required more alkali and gave lower yields than barked materials....

Abstract

The site requirements of Populus tremula X P. tremuloides are discussed, and it is suggested that it could be grown in many places in Finland, though damage by moles is a risk. In fertilizer trials, N favoured the growth of seedlings, but P and K had no clear effect. Susceptibility to Valsa nivea...
