Truffles grow also in Estonia
Leho Tedersoo and Triin Nadel introduce the strange-looking fungi with high culinary qualities. A truffle is basically a fruiting body of an underground mushroom. Truffles, as all underground mushrooms, are very dependent on mammals that spread their spores. Therefore, the truffles attain the specific smell once the spores have ripened to attract different mammals. Most mushrooms with underground fruiting bodies also have symbiotic relations with forest trees, called ectomycorrhiza.
70–75 species of truffle mushrooms have been described in the world; 5 of of these have been identified also in Estonia, but there may be more. None of them are edible, but they are not poisonous, either. The article also covers the culinary use of truffles.

Estonian nature protection 100: Jaan Eilart and his era

15 years of nature protection orientated care of coastal meadows in Estonia
Marika Kose, Murel Merivee and Annely Reinloo sum up the efforts made to preserve coastal meadows – heritage communities. To a very large extent, the management of coastal meadows depends on local people and their cattle, who in turn are dependent on project money to support cattle-raising in non-productive areas. In the last 15 years, project money has helped to restore over 3000 ha of coastal meadows and to manage over 4000 ha of coastal meadows.

Business with endangered species

Dissertation: Woods of hybrid aspen are now in the middle of their lifecycle.
Arvo Tullus introduces the first results about the growth and increase of the fast-growing tree species, and discusses about factors influencing the growth. While ordinary aspen woods are cut down at the age of 50, the woods of hybrid aspen are ripe for the axe 30 years after planting. The research has shown that hybrid aspen grows very fast in Estonia, especially on fertile soils.
