Studies carried out in 2001-2003 were aimed at evaluation of the current structure and conditions of the population along with the recording of biometric traits of downy willow specimens at their natural stand on Lake Bikcze. It has been found that the population of downy willow on the peat bog near Lake Bikcze has much increased since the 1950's. The character of phytocoenoses, where Salix lapponum occurred most abundantly, may prove its wide requirements in terms of habitat conditions. S. lapponum specimens were in good condition. Furthermore, blooming of male and female specimens as well as great viability of pollen grains was recorded. High variability of selected biometric traits for studied species' specimens was found.
