Exotic woody weed plants are a very serious threat to seed dispersed by ungulate in the tropical forest of Asia. The ungulates in Point Calimere Wildlife Sanctuary (PCWS) are a significant role in native indigenous seed dispersal. The exotic woody weed tree prevalence distributed in the PCWS and they might potentially alter the native medicinal plant species. In the present investigation, we have assessed the seed dispersal by ungulates in PCWS from January to March 2017. Four different ungulate species were selected to understand their seed dispersal rate of different plant species in selected sanctuary. This investigation was planned to confirm the seed dispersal by ungulates of blackbuck, spotted deer, wild boar and feral horse. Among the four different ungulates tested, the maximum numbers of pellets collected from blackbuck and no seed found in their pellets. The low quantities of pellets were collected from wild boar and this study has recorded medium-sized ungulates which dispersed variety of plant. However, the dispersal of the seed of medicinal plants were not considerably high and relatively moderate percentage of seeds dispersal occurred in medium-sized ungulates like wild boar and spotted deer. had 100% seed germination rate were observed from the faecal samples of wild boar and feral horse. The control seed achieved maximum seedling rate than the ungulates seeds.
外来木本杂草植物对亚洲热带森林中有蹄类动物传播的种子构成了非常严重的威胁。卡利梅尔角野生动物保护区(PCWS)的有蹄类动物在本地原生种子传播中发挥着重要作用。分布在PCWS的外来木本杂草树很普遍,它们可能会改变本地药用植物物种。在本研究中,我们评估了2017年1月至3月PCWS中有蹄类动物的种子传播情况。选择了四种不同的有蹄类动物物种,以了解它们在选定保护区中对不同植物物种的种子传播率。本研究旨在确认印度羚、花鹿、野猪和野马等有蹄类动物的种子传播情况。在测试的四种不同有蹄类动物中,从印度羚收集到的粪便颗粒数量最多,但其粪便颗粒中未发现种子。从野猪收集到的粪便颗粒数量较少,本研究记录了传播多种植物种子的中型有蹄类动物。然而,药用植物种子的传播率并不高,在野猪和花鹿等中型有蹄类动物中,种子传播的比例相对适中。从野猪和野马的粪便样本中观察到种子发芽率为100%。对照种子的幼苗率高于有蹄类动物传播的种子。
