To provide some ecological information on protection and management of the mixed heronries, their distribution, breeding species and individual numbers, and site characteristics, which may be important to heron ecology, were investigated in Jeollanam-do during the 2005 breeding season. As a result of this census, 17 mixed heronries, containing a total of six ardeid species were found. Among those species, Great Egret (Egretta alba) and Grey Heron (Ardea cinerea) were found to breed in most sites (both 92%) and were most numerous (36.3%, 31.0% respectively). Many of the heronries (53.3%) were located within the bamboo forest. Other site characteristics were as follows: the mean area dimension of heronry was $2,346m^2$ with the range of $500{sim}7,000m^2$ the mean distance between the two nearest heronries was 18.1km with the range of $5.6{sim}40.4km$ the mean distance to the nearest village was 297m with the range of $10{sim}2,000m$ the mean gradient of the topography was $18^{circ}$ with the range of $2^{circ}{sim}40^{circ}$, and 40.0% of the heronries were located in the eastern slopes. |
