Marjut Turtiainen, Olli Saastamoinen, Kari Kangas, Matti Vaara. (2012). Picking of wild edible mushrooms in Finland in 1997–1999 and 2011. Silva Fennica vol. 46 no. 4 article id 911.
This study reports on national survey results concerning mushroom picking in Finland during four separate years: 1997–1999 and 2011. The material was collected by mailed questionnaire surveys amongst Finnish households. The sample size varied from 1858 (in 1998) to 6849 households (in 1997) and the response rates varied from 51% (in 2011) to 70% (in 1999). The results indicate that both the rate of participation in mushroom picking and estimates of the quantities collected varied greatly depending on whether the survey was conducted in a favourable or unfavourable year. In 1998, when the mushroom crop was abundant, a total of 47% of all households were engaged in picking and the total harvest was 16.1 million kg. In 1999, when the crop was poor, the estimates were the lowest (23% and 3.3 million kg, respectively) and in a year with a relatively abundant crop (2011), the estimates were 42% and 15.0 million kg, respectively. Mushrooms were collected mainly for home use, which accounted for 85–90% of the total harvest depending on the year. Only a small proportion of all households (0.3–1.3%) were engaged annually in commercial mushroom picking. In 1997–1999, milk caps formed the major part of the total amount picked (i.e. 37–53% depending on the year), whilst in 2011 their share was approximately one fifth of the total harvest. The results also indicate that the proportion of ceps in commercial picking has increased since the 1990s

Olli Saastamoinen, Seppo Lohiniva. (1989). Picking of wild berries and edible mushrooms in the Rovaniemi region of Finnish Lapland. Silva Fennica vol. 23 no. 3 article id 5387.

According to 459 and 350 questionnaires sent in 1983 and in 1985, respectively, the households in the Rovaniemi region located in the Arctic Circle in Northern Finland, eagerly picked wild berries. In both years, four out of five households picked at least one species of berry. In 1983 the total amount of wild berries picked was 29.2 kg per capita. In 1985 it was 15.0 kg per capita. Three species, the lingonberry (Vaccinium vitis-idaea L.), cloudberry (Rubus chamaemorus L.) and bilberry (Vaccinium myrtillus L.) made up 96% of all the wild berries picked during both years. Most of these berries were picked for the family’s own use, but many were also picked for sale. In 1983, 43% of all berries picked were sold, in 1985, 19% were sold. The cloudberry, although difficult to find, is the most important commercial species and also for household use it is the most sought after wild berry. Only very small amounts of edible mushrooms were collected, 1.0 kg per capita in 1983 and 1.3 kg in 1985.

English title: Ten-year effects of breaking the soil surface on the yield of Gyromitra esculenta.

The yield of Gyromitra esculenta (Pers.) Fr. was surveyed during 1973–82 in a Norway spruce (Picea abies (L.) H. Karst.) dominated stand in Central Finland. The soil surface was treated with different light methods, mainly removing the vegetation and humus layer.

It was shown that is possible to improve the natural yield of G. esculenta by breaking the soil surface. In the 286 m2 of treated the yield could be improved over 50 fold compared to the control area. In the untreated control area, the yield per hectare was 0.98 kg/yr. In treated plots the yield was 52.4 kg/yr (in the best year 191 kg/ha/yr). Fruit bodies of G. esculenta were found in treated plots every year after the soil treatment. The yield was at its best in the two first years declining later to the level of 10–20% of the first year’s yield.

The best natural yield was reached in the last year. The previous year’s precipitation was an important factor influencing the yield of the mushroom.
