  • Trema orientalis seeds dispersing by birds were studied at Mengsong and Menglun areas,Xishuangbanna,Yunnan Province.It was observed and recorded that species of birds eating T.orientalis fruits in the field.Different types of mist nets were employed at forest edges and gapes,as well as near the ripe fruit trees.Birds to eat the T.orientalis fruits were mist-netted in field,each bird was placed in a separate cloth bag,its excreted feces was collected,and the seeds in bird feces were checkuped.36 species of birds have been recorded to consume the T.orientalis fruits,and fecal samples from 26 species by mist-netted were gotten.Germinating experiments were conducted through sowing a kind of ripe fruit and two kind of seeds of T.orientalis in 4 conditions.The ripe fruits of T.orientalis were directly sowed,they could not germinate and were easily decay.The seeds separated by handwork from the fruits could germinate.The seeds excreted by nature from birds had a very high rate of germination.It is suggested that the seeds had changed from dormancy into activity while the T.orientalis fruits consumed by the birds.Birds took the seeds to the forest edges and newly cut areas that more suitable for germination and seedling growth.There are ecology reciprocal role between birds and T.orientalis.
