Erosion protection landscaping embedment of steep subsoil slopes is a time-sensitive issue of road construction and planning of recreational area that are often fit on a challenging picturesque terrain unsuitable for site development. The article provides the results of a 4-year experiment on landscaping and plant fixing of up to 4.5 m soil slopes with 1:1 and 2:1 grades; the experiment was carried out by the MGSU on the territory of a convent in the south of the Nizhniy Novgorod region. The site has slopes oriented towards all cardinals. At some places the slopes are bedimmed by trees. All these factors create a wide range of geo-ecological conditions for lawns. All the slopes are fixed with geo-fibrefill grids; slopes with 2:1 grade are strengthened by auxiliary grids made of reinforced metal bars, anchors and braces on the bottom of the Holy Moat. The paper recommends composition of grass plants as well as techniques to build up lawns suitable for various micro-climate conditions. It also advises the structure of multi-tier plant entity. The suggested methods are tested during a 3-year maintenance of slopes built for constant use.
