Among them is the elm of Istra, located near Ludza manor in the east of the country.
It is estimated to be around 200 years old and was planted as an integral part of the surroundings alongside the 19th-century manor house as part of a series of avenues of trees which can still be seen.
Razna national park expert Regina Indrike told Latvian Radio: "It's quite an unusual great tree... the branches only begin about 6 meters from the ground. We don't have many such trees in Latgale [Latvia's eastern district] and in fact through the whole of Latvia you won't find such a wonderful and beautiful elm.
"Surrounding the tree you can see it has around twenty young children... but it's a shame that the surrounding territory is not so well maintained these days, as it could be a lovely place for people to visit."
