The modern digital archives of biodiversity
Ivar Puura gives an overview of the current state and perspectives of the digital archives of Estonian biodiversity. Data bases like that are designed to meet multiple purposes: for one, to serve scientific aims; secondly, educational and informative purposes and thirdly, aims supporting juridical decisions. The project to launch Estonian Biodiversity Data Base was launched in 2006. This one gives the most complete list of Estonian species, thus creating a basis for developing other scientific digital archives. There are also data bases like EELIS – the Estonian Nature Information System, Nature Observations Database, public portal called e-Biodiversity and a few others.

The green network of a settlement: for whom and how much?
Kadi Tuul discusses over the necessity of green areas in towns: the green belts help to improve people’s health, but also create important habitats for biodiversity. The author starts with the history of green belts. In Estonia, most large towns have a green belt designed mostly in 1950ies. In 1970ies, the idea of green network started to grow in Europe, with the aim to join all natural and seminatural areas with nature conservation purposes into one. The new and complete guide for creating green networks as part of county thematic plan was completed in 2003 in Estonia. However, little attention has been paid to green areas in towns, also known as nearby recreation areas. The article shares some international experience in planning those areas and looks also in Estonian practice.

Red Helleborine: beautiful, but for how long?
Toomas Hirse shares the results of last year’s inventory of orchid habitats, which, however, are not very promising. It was quite clear that many habitats have been lost. In Estonia, the Red Helleborine grows mostly in alvar forests; therefore most habitats are located on West-Estonian islands and the Pandivere Upland. About 64% of the territory of habitats is under nature protection.
