Lots of willows and a few willow trees

lle Reier makes an introduction to the Tree of the Year; the willow tree. There are 15 species of willows in Estonia and some 450 species in the world, but people do not know them well and usually consider all willows as bothersome brushwood species.

How many mires are in Estonia?

Raimo Pajula rebuts the myth of Estonia being rich in mires. In fact, alive mires cover only 6% of the non-aquatic territory of the country. Statistically, however, it is known that mires cover 22% of the territory. Where does such a difference come from? About half of this 22% is forest land mostly drained peatland forests and drained and afforested treeless peatland mires. A research carried out for designating the Natura 2000 mire habitat types gave a rough estimation of only 6-7% of Estonian territory being covered with natural mires. Most wide-spread mire type is bogs, followed by ruined, but renewable bogs and paludified peatland forests.
