Community Characteristics and Conservation Strategies of A Rare Species, Dipteronia dyeriana ( Aceraceae)

Abstract

Abstract:

Rare plant Dipteronia dyeriana distributed on the Laojun Maintain in Wenshang, Yunnan, southwest of China, the mountain is located in south sub-tropics. D1 dyeriana was only found at the zone from 1800 m to 2200 m above sea level. The
habitat of D1 dyeriana was cool and moist. D1 dyeriana was a heliophyte and did not grow well under forests. On the Laojun Mountain most of its individuals was in D1 dyeriana communities, some was in other shrubberies and a few was on the edge of forest communities. Disturbances played an important role in the formation and ex istence of the D1 dyeriana community. It should not result in extinction of D1 dyeriana that other trees were cut down in its distribution. Recovering of forests should result in decreasing the number of its individuals in the area. Clear- cutting for cultivation would be the most serious threat to D1dyeriana. To remain large population of D1 dyeriana disturbances were necessary.

Key words: Rare Plant, Dipter onia dyeriana, Community characteristics, Conservation strategies
