English title: Experiences of curly birch growing in north-western Russia.

Curly birch (Betula pendula var. carelica (Merklin) Hejtmanek) is widely distributed over north-western part or Russia, including the Baltic Soviet Republics and Belorussia. Experiences of growing this decorative species in Soviet Karelia and Leningrad region are presented. Commonly used classifications of the species are described, and recommendations for management of curly birch cultures and production of planting stock in greenhouses are given.

English title: Selection system in timber harvesting in Finland.

This article reviews experiments and practical experience of forest management by the selection system in Finland. In an experiment of 25-year duration the annual growth of uneven-aged Norway spruce (Picea abies (L.) H. Karst.) stands was only about 50% of the average annual yield of even-aged stands in normal rotation on the same site.

In Finland the selection system is applicable under exceptional conditions only, viz. In intensively managed park stands and, on the other hand, on very marginal sites, e.g. on peat bogs and mountains near the tree-line. Even normal silviculture, however, may include cuttings which somewhat resemble selection system, e.g. removal of standards or restoration of mismanaged forests.

Simo Poso, Tuomas Häme, Raito Paananen. (1984). A method for estimating the stand characteristics of a forest compartment using satellite imagery. Silva Fennica vol. 18 no. 3 article id 5219. https://doi.org/10.14214/sf.a15398

The paper presents a method based on two phase sampling and applicable to forest inventories. The first phase estimates are obtained from satellite imagery and, if required, from extra material such as maps. Second phase estimates are measured in the field. The method is flexible and also applicable to compartmentwise forest inventories. The experiments were based on six study areas with 439 relascope plots. The correlation coefficients between first and second stage estimates varied largely according to the study area.

English title: The occurrence of Otiorrhynchus nodosus and its significance for the natural regeneration of Scots pine in Lapland.

The aim of the present study was to survey the occurrence of Otiorrhynchus nodosus Müller weevils and their significance for the natural regeneration of Scots pine (Pinus sylvestris L.). The study was carried out during summer 1982 at Inari in northern Lapland.

There were two sample plots, one situated in a Scots pine seed-tree area and the other, the control sample plot, in an area with a coverage of mountain birch (Betula pubescens subsp. tortuosa, now subsp. czerepanovii). A total of 177 Otiorhynchus weevils were caught. Movement of the weevils reached its climax in July. There were 86% more individuals in the seed-tree area than in the mountain birch area. No damage to the pine germlings or seedlings was not observed, although the situation could be different during the peaks of the veewil populations.

English title: Observations of forest specialists in Northern Finland on the berry yield capacity of forests and swamps.

A survey was carried out among forest foremen and forest technicians to record their observations on the value of various swamp and forest types as producers of berries and on the effect of drainage of peatlands upon the berry yields. Comparative agreement existed on the best blueberry (Vaccinium myrtillus L.) forest types and on the best lingonberry (Vaccinium vitis-idaea L.) forest types of rather dry upland sites. Fuscum pine swamps or fuscum bogs were considered best for the most part as regards the yield of cloudberry (Rubus chamaemorus L.). The replies showed rather great dispersion.

Agreement existed as well on the relation between drainage of peatlands and the yields of our economically most important swamp berries, cloudberry and cranberry. 90% of those responding were of the opinion that drainage reduces the cloudberry yield in the long term and a full 97% indicated that cranberry crop diminishes as well.

A total of 146 Norway spruce-dominated clear-cutting areas and 140 of the sample plots included in the 7th National Forest Inventory in Finland were examined during 1974–78. The micro-organisms causing decay in Norway spruce (Picea abies (L.) H. Karst.) sample trees were identified. The most common causal agent of butt-rot was Heterbasidion annosum (Fr.) Bref. Other fungi causing decay in the spruce trees were Armillaria mellea (Vahl.) Quél, Stereum sanguinolentum (Alb. & Schw. ex Fr.), Resinicum bicolor (Alb. & Schw. ex Fr.) Parm. and Climacocystis borealis (Fr.) Kotl. & Pouz. Species of Ascocoryne were very often present in the decay. The decay caused by H. annosum was considerably more extensive than cases of decay where the fungus was not present.

English title: Picking and use of edible wild berries in Central Finland during 1978–81.

The picking and use of wild berries were investigated in five municipalities in Central Finland during 1978–81. The picked amounts per person were in average 17.6 litres of lingonberry (Vaccinium vitis-idaea L.) and 5.6 litres of bilberry (Vaccinium myrtillus L.). 54%, of lingonberries were consumed by the families who picked them, 43% was sold and 3% was delivered to others. Of the picked bilberry yield the figures were 74%, 24% and 2% respectively.

About 86% of the families picked lingonberry and 79% of the families picked bilberry in five municipalities in Central Finland during

English title: The yields of the edible wild berries in Central Finland.

A study on wild berry-bearing plants was made in five municipalities in Central Finland during 1978–81. Yield of lingonberry (Vaccinium vitis-idaea L.) was 8.0 kg/ha of forest area. Bilberry (Vaccinium myrtillus L.) produced 4.3 kg/ha and black crowberry (Empetrum nigrum coll. L.) 1.5 kg/ha. Lingonberry comprised 40%, bilberry 27% and black crowberry 14% of the total berry yield. Any other species produced less than 10% of the total yield. Lingonberry produced high yield in clear-cut areas and in old Scots pine dominated forests but bilberry production was restricted almost completely to old sparse forests.

The total lingonberry yield in Finland was estimated as 180 million kg and the total bilberry yield as 150–200 million kg. About 80% of the lingonberry yield and 60% of bilberry yield was judged to be gatherable on the basis of the yield.
