Berry yield of rowan tree (Sorbus aucuparia L.) was studied by picking and weighing the berries in a tree, counting the number of clusters by the eye, estimating the number of clusters by samples of 0.5 m2, and by counting the dropped berries. In the last tree methods average weight of berries in a cluster was assessed by weighing a sample of clusters. The size of the tree and the abundance of the berries influenced the choice of method. The first two methods suited for small trees, the third for a tall tree with berries in abundance, and the fourth for those cases where birds had eaten a large portion of the berries.

The berry yields of 88 rowan trees were studied in Central Finland in 1983, a year of exceptionally high berry yield. The yield of berries averaged 23 kg per tree, the number of clusters 1,249 per tree and the number of berries 42,500 per tree.

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

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.

A study on the bilberry (Vaccinium myrtillus L.) was made in the municipality of Pihtipudas (about 63° 30’ N, 23° 30’ W) in 1977. Berry yield was surveyed by picking along 17 lines, each 1,000 m long. The lines were chosen randomly and were situated on different vegetation types throughout the municipality. The picking and use of bilberries were studied by an inquiry addressed to a random sample of families living in the area. Marketing of bilberry was investigated by means of report based on purchasing certificates.

The total yield of bilberry in Pihtipudas was 2.4 million kg (21.9 kg/ha). The yield per hectare were best on Vaccinium and Myrtillus type sites, and on swampy heath sites, where the yield was about 27–65 kg/ha, 50% of the yield on the Vaccinium type and 25% of that of Myrtillus type. Only 1.8% of the total bilberry yield was picked from old forests. Women contributed 54, men 34 and children 12% of the volume.

72% of the berries were used for home consumption by the families, 24% were sold and 4% were used for other purposes. The earnings from bilberries for the families that sold berries was in average FIM 178.

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.
