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.

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.

English title: The berry yield, picking, and marketing of Vaccinium vitis-idaea in the commune of Pihtipudas, Central Finland.

A study on the lingonberry (Vaccinium vitis-idaea L.) was made in 1976. The berry yield was studied by picking along 17 lines, each 1,000 m long. The picking and use of lingonberry were studied by an inquiry addressed to the families engaged in such an occupation. The marketing of the lingonberry was investigated by interviewing purchasers, and by means of reports based on purchasing certificates of the purchacers. The total yield of lingonberry in Pihtipudas was 1.2 million kg or 18 kg per hectare of productive forest. Only 7% of the total yield of the berry was picked. 47% of the lingonberries picked were used by the families themselves, 48% were sold and 5% were used for other purposes. The families who sold lingonberries earned, on an average, 350 Fmk.

English title: Studies concerning the relationship between biomass and coverage in ground vegetation of a forest stand.

The study deals with the relationship between biomass and coverage in ground vegetation of Vaccinium and Calluna forest types. The results show that the biomass of the field layer on both forest types can predict satisfactorily in both coverage values of some the most important species and groups of species. Their total height per plot was used as independent variables. The explaining power of the models constructed for Vaccinium type increased to approximately 57% and for the Calluna type to approximately 74% of the total variation in the amount of dry matter. When the biomass of the bottom layer was predicted using the same kind of variables, the explaining power for the Vaccinium type increased to approximately 35% of the total variation and for the Calluna type approximately 53% of the total variation in the amounts of dry matter. The models for field layer of both Vaccinium and Calluna types were quite well suited for describing the test material. In the case of the bottom layer, the constructed models were not suitable for describing the test material.
