海南坡鹿(Cervus eldi hainanus)仔鹿对卧息地的选择

THE SELECTION FOR THE BEDDING REST PLACES BY THE FAWN OF HAINAN ELD'S DEER (Cervus eldi hainanus)

1986年和1987年的10月至12月共发现14个海南坡鹿仔鹿的卧息地。研究表明,仔鹿对卧息地的选择不受母鹿影响。在保护区围栏内的多种栖息地中,仔鹿对次生落叶季雨林白下的茅、黄茅草坡有明显偏爱,有12个卧息地被发现于这种环境中。该环境在每10平方米面积内约有1—2株小乔木,30一60株灌木,草本植物高于50厘米,通视条件良好。仔鹿对卧息地的选择似乎与水源无关,但不能排除风向对仔鹿选择卧息地坡向有所影响。适当地清除过于密集的灌丛,有利于仔鹿栖息。

Total 14 bedding rest places for the fawn of Hainan eld's deer were found during the birth seasons from October to December in 1986 and 1987. The fawns select bedding rest places by themselves and are not intervened by their mothers. The fawns prefer grass slopes with Imperata cylindrica, Heteropogon contortus under the canopy of the secondary deciduous seasonal raining forests when they select their bedding rest places. Twelve out of fourteen bedding rest places were found in this habitat type, which pro-portion is much higher than those of the available part and other habitat types in the study area. The fawns randomly select the grass slopes with Cleistanthus sp. and I. cylindrica as their bedding rest places. The bedding rest places happen in the environment in which the densities of tree and shrubs are of 0.5-2 individuals per 10 square meters and of 3 - 6 per square meters respectively, and grass with yellowish color is over 50 cm high. No any correl-ativity is existed between bedding rest place and water resource. The influence of wind direction on the slope aspect of the bedding rest places could not be rejected.
