Be sure to not let the unwanted passenger get away Fortunately, a large animal cannot fit in a suitcase, but some smaller animals, such as a scorpion, gecko, smaller reptile, cockroach, snail, or spider may accidentally hide in a bag and travel to Estonia. What should I do if I get back home from a trip and find an unwanted passenger in my bag? If you think the animal that accidentally ended up in...

The Estonian water network is dense, because the amount of precipitation exceeds evaporation here Watercourses There are thousands of watercourses in Estonia – according to the literature, more than 7,300 – with a total length of more than 31,000 km [1]. There are almost 3000 watercourses registered in the Estonian Nature Information System [2]. Most Estonian watercourses are short (94.3%), up to...

Inland waters form very diverse habitats Inland water bodies vary in size, depth, amount and nature of solutes, water flow rate, the characteristics of the bottom, water temperature, and many other aspects. Their combinations form very different habitats inhabited by very different species. The number of species usually increases with the increase in the area or catchment basin of a water body, as...

EU Member States must work to ensure that all bodies of surface water are at least in good condition The pollution of surface water bodies with hazardous substances in Estonia occurs primarily in connection with pollution from oil shale production in Ida-Viru County since the 1930s. However, a more significant pollution load from agriculture (manure, fertilisers, pesticide residues) arose during...

The Water Act defines a water protection zone on the shores of water bodies, while the Nature Conservation Act defines a building exclusion zone and a limited management zone Inland waters are a natural resource that are important as valuable habitats, animal routes, but also for recreation and the protection of the aquatic environment. In order to preserve the natural condition and diversity of...

The flora and fauna of Lake Peipsi are rich in species Lake Peipsi is one of the largest lakes in Europe. The lake has an area of about 3,543 km 2, a length of about 135 km, a width of 48 km, an average depth of 8 m, and a maximum depth of 17.6 m [1]. The lake is divided into Lake Peipsi (Suurjärv), Lake Pihkva, and Lake Lämmijärv. The basin of Lake Peipsi covers 47,802 km 2 – it is larger than...

The biota of Lake Võrtsjärv is quite rich in species – 35 species of fish have been found here Lake Võrtsjärv is the second largest lake in Estonia. It has an area of about 270 km 2, a length of about 35 km and a width of 15 km in the north, an average depth of 2.8 m, and a maximum depth of 6.0 m. The catchment basin of Lake Võrtsjärv covers 3,380 km 2 [1]. Lake Võrtsjärv is a flow-through lake...

More alien species are found in anthropogenic habitats than in natural habitats There are a wide variety of species in the anthropogenic habitats, from the first inhabitants of waste lands and landfills, many of whom are considered weeds (e.g. dandelion, plantains), to exotic plants planted in parks and arboretums. Anthropogenic terrestrial habitats can be broadly divided into two: purposefully...

Heritage meadows have been created as a result of nature-friendly management Coastal meadow is a grassland on the sea shore that is more or less affected by saline seawater. Coastal meadows are located in flat, turfed coastal areas. As animals have historically been grazed there, they are therefore also called coastal pastures or coastal grasslands. Coastal meadows are mainly located in Western...

Since 2002, the Estonian national curricula have included the cross-cutting theme ‘The environment and sustainable development’ Aristokli Hrebtov, the inspector of the schools of Saaremaa and the founder of the Saaremaa Society of Friends of Nature (founded in 1913), prepared a detailed circular letter for schools, titled ‘For the preservation of nature works’, in which he called on people to...
