Restoration of bogs in Estonia solves several burning problems

Estonian environmental NGO-s and the Ministry of Environment have launched massive projects related to our boglands. The total area of swamps and bogs has decreased substantially since the middle of the 20th century. Recent inventories reveal that the situation is much worse than we thought and we must work hard now to reverse ths process.

Estonia is a land, that has uplifted from the sea during the last 12,000 years and therefore is full of previous lagoons, overgrown lakes, swamps and raised bogs. We are used to the myth, that Estonia is full of bogs. In 2011-2013, Estonian Fund for Nature completed a project, funded by the Coca Cola Foundation, which aimed in finding the best restoration areas of the Estonian Ramsar sites and compiling restoration plans. The main focus was on transitional bogs, as these are usually grown instead of open bogs as a consequence of amelioration. It is shocking to realise that instead of the textbook reference of Estonia being 22% swamps and bogs, the reality is that only 5.3% remains (according to the inventory from 2009-2012, made by Estonian Fund for Nature, Tartu University and NGO Arhevisioon). The disappearance of bogs since 1950 has been become critical and should be a real cause for concern!

Beginning with this year Estonian Fund for Nature launches a new five-year cooperation programme with the upper mentioned partners to restore 5800 ha of bogs, damaged by amelioration and drainage. The project is still in the preparation stage, as the practical work should begin in 2017. The plans embrace 5800 ha of bogs to be restored, 3276 ha of Natura habitats therein and is financed by LIFE Programme and Environmental Investments Centre. In addition to practical work in landscape lots of information work will be done. The main idea is to restore as natural a water-regime as possible to relaunch peat accumulation processes. Alam-Pedja, Ohepalu, Agusalu, Lahemaa, Tudusoo, Sirtsi and other nature reserves and national parks will be included in the project which will run until 2020.

At the same time the State Forest Management Centre (RMK) is launching another programme to clear overgrown bog areas to restore the bog to its former glory. The main focus is on 5000 hectares of different valuable areas.

It was more than 40 years ago when a “Bog War” took place in Estonia. Pragmatism vs conservationism. Peat vs water. By that time edges of the largest bog massives were already cut through by ditches and the function of bogs as water reservoirs was perturbed. This Moscow-financed operation was a hot topic in newspapers and radio for 3 years, until some Estonian ministers switched their side and became “bog-keepers”. In 1972 the Council of Ministers specified the bogs that were to be excluded from the amelioration fund. All together 93 bogs and swamps (207,000 ha) were listed, from which 28 bog and swamp reserves were established in 1981 (total area 100,000 ha).

After the restoration of independence in Estonia utilitarian interests began to prevail and  peat excavation became a large scale problem with international business interests. The crucial question is whether peat is renewable natural asset or not. Our bogs have come into being since the latest ice age and accumulated peat at a rate of 1 mm per year. According to this knowledge the usable peat stock is about 2.8 million tonnes. However, large amounts of peat is quickly vanishing through decomosition resulting in mineral soil plus lots of carbon dioxide emission – an even worse problem.

The problem is as complex as it gets. We have to consider the pure water reservoir, accumulated carbon dioxide, ability of bogs to produce more oxygen than it uses itself, the habitat of rare and threatened mammals, birds, invertebrates and plants - plus the wonderful asset of our time - silence!

It is easy to make a list of the most important species of interest, more or less related to bogs, swamps and adjacent transitional areas: Capercaillie, Moor Frog, Willow Ptarmigan, Hazel Grouse, Black Grouse, Common Crane, Great Grey Shrike, Whimbrel, Jack Snipe, Wolf, Elk, Brown Bear, Golden Plover, White-faced Darters, Cranberry Blue, Freija Fritillary, Bog Fritillary, Baltic Grayling etc. The orchids of interest are Musk Orchid, Fen Orchid, Heath Spotted Orchid, White Adder’s Mouth, Bog Orchid, Narrow-leaved Russow’s Orchid and others.

Estonian Nature Tours takes its clients to several of these reserves, e.g. Lahemaa, Tudusoo, Alam-Pedja etc.
