A nice postcard showing the aerial view of Victoria Falls and Bridge, on the border of Zimbabwe and Zambia. I also like the beautiful bird definitive stamp issued in 2001. Thank You very much to my friend !
The Struve Geodetic Arc is a chain of survey triangulations stretching from the Black Sea to Norway’ northern coast on the initiative of Friedrich Georg Wilhelm Struve (1793-1864) for the measurement of the shape and size of the planet Earth. The length of the arc is 2,820 km. When the arc was created and more than a century later it was the longest measured meridian arc. It passes through the territory of today’s Norway, Sweden, Finland, Russia, Estonia, Latvia, Lithuania, Belarus, Moldova and Ukraine. The original arc consisted of 258 main triangles and 265 main station points. Thirty-four of the original station points today survive, and three of them are situated in Estonia, one in the Tartu Observatory and two in Simuna in the West-Viru County. Since 2005 the Struve Geodetic Arc is a UNESCO world heritage site.
Estonian forests belong to the mixed forests zone and the most widespread forest type is where evergreen conifers dominate, but there are also deciduous forests. The most common tree being the pine, followed by the birch and the spruce. The biggest forests in the country lie in the north eastern and central parts of Estonia. It is quite common to meet rabbits, foxes or roe deer, and the biggest animal is the elk. The forests are home also for a number of species on the verge of extinction, such as the European mink, the dormouse and the flying squirrel.
