Benefit: Harvested yield
The benefit of berries and mushrooms can be assessed by the proportion of the total harvested yield. Majority of berries and mushrooms are collected for domestic use and do not enter the markets. Therefore the harvested yields cannot be accurately compiled from the statistics.
Examining the amounts of berries and mushrooms entering the markets can give perception on the harvested yields. However, Finnish Forest Institute has evaluated that 60–95% of the berry harvest stayed in domestic use in 2000s. The share is approximately the same for mushrooms, ca. 60–90% of the harvest are picked for household use.
The largest berry volumes on commercial markets consist of bilberry and cowberry. In 2013 about 860 000 kg of bilberry and 760 000 kg of cowberry was delivered to the retailers. Compared to these quantities the yields of other berries in commercial markets are minimal and the data have not been collected every year. The yield of cloudberry fluctuates strongly annually. During the past decade the quantity in commercial markets has varied between 130 kg and 36 000 kg. The data on yields of crowberry and cranberry in commercial markets have been collected only in some years. The quantity of crowberry has been from 4 000 kg to 67 000 kg annually. The quantity of cranberry has been collected only in 2007 when it was about 4 000 kg.
The annual yield of mushrooms varies considerably. The most common mushrooms on commercial markets are ceps, milk caps, chanterelle and winter chanterelle. The volume of ceps in commercial markets has been around 350 000 kg annually on average during the past fifteen years, but there has been some years when the cep yield has peaked such as 2003 and 2010. The milk caps include northern milk cap, rufous milk cap and woolly milk cap which are the most common milk caps on commercial markets. Their volume has been approximately 200 000 kg during past fifteen years.
The volumes of chanterelle and winter chanterelle vary even more extensively than that of ceps and milk caps. Especially the volume of winter chanterelle on commercial markets has fluctuated between 10 kg and 90 000 kg annually during 1998–2012. Approximately the volumes of chanterelle and winter chanterelle has been altogether around 40 000 kg annually. Other mushrooms include false morel, horn of plenty, Albatrellus ovinus, velvet bolete, wood hedgehog, false saffron milk cap, saffron milk cap, Morchella conica and russulas. These are mostly used in domestic households and are uncommon on commercial markets.
