Genko's Forest Belt, Protected forest belt in Ulyanovsk Oblast, Russia.

Genko's Forest Belt is a protected woodland system in Ulyanovsk Oblast that contains oak, maple, pine, birch, linden, and elm trees distributed throughout the area. The forest functions as a connected green barrier designed to shield the land from wind while housing trees of different ages.

Nestor Karlovich Genko (1839–1904), a Russian forester, drew up the plan and directed watershed protection planting between 1886 and 1903. The strips became known as the Genko belts. In 1989 the Ulyanovsk regional executive committee declared them a natural monument by decree No. 552.

Locals call the strips "Genko's belts" after Nestor Karlovich Genko, the forester who led the planting. The oaks, maples, pines, birches, lindens and elms were set in rows to break the wind across open farmland, and the same strips still shelter the fields between Vidny and Novosyolki.

The belt runs from the settlement of Vidny to Novosyolki in Ulyanovsk Oblast, crossing open farmland, so it is reached by road rather than by a marked trail. Building, farming and clear felling are banned; only sanitary removal of dead trees is allowed. There are no visitor facilities or guided programmes.

The woodland demonstrates natural regeneration with multiple generations of trees that continue the windbreak's original purpose. This self-sustaining structure shows how a design from the 19th century still performs its protective function today.
