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.
