The aim of the studies was to evaluate the persistence of perennial ryegrass in the pasture sward. The studies were carried out over 1994-2000 on black earth and muck-and-peat soil at Sosnowica, Poland. The share of perennial ryegrass in the pasture sward changed depending on the sequence of regrowth, habitat moisture and temperature course in the autumn-and-winter period. Irrespective of the soil type, the highest winter damage of perennial ryegrass and greatest reduction in the share of the species were recorded in the sward following 1995/1996 and 1996/1997 winters.
