摘要：Monitoring of successive stages of alder stands (Aldus glutinosa) from natural regeneration on abandoned agricultural lands was realized in 2008 and 2009. Analysed alder stands arose on silt deposition after local flooding in 1998. Stand analysis were realized on the circular plots (10 m2 each) in regular networks. Alder dominated in both stands. Basic stand characteristics differed due to different stand density, 20 a 43 m2/ha. Thin trees dominated in both stands, high production potential indicates the thickest trees (over 10 cm). High number of trees positively influenced tree quality. Measurement did not confirm the relationship between light and stand density on circular plots. Vital weed occurred on both stands.
