Abstract

Abstract: In order to study the effect of Milu deer （Elaphurus davidianus） activity on the seed bank in the Swan island wetland in Shishou county, seed bank germination experiment and vegetation investigation were carried out on the basis of the strong and weak selection of three sites （A site, B site and C site） by the intensity of interference. The results showed that there were 41 species, 18 families, 39 genera, and mainly annual plants （53.7%）. The interference intensity of Milu deer had a significant effect on seed bank in the Swan island wetland in Shishou county （P<0.05）, and the order of the interference in the seed bank species was B>C>A. The variation characteristics of Shannon-Wiener diversity index and Margarlef richness index of above ground vegetation were the same, and both showed an extremely significant downward trend with the decrease of disturbance intensity, indicating that disturbance increased the species and quantity of above ground vegetation. The similarity level between seed bank and above ground vegetation was low, the number of Milu eaters in above ground vegetation decreased, and a large number of Milu anorexia species increased.

Key words: MiLu deer （Elaphurus davidianus）, seed bank, interference, habitat, Swan island wetland
