“…On both islands, alien plants dominate only in disturbed urban and agricultural areas, although this dominance can apparently persist on some sites after disturbance is halted (e.g. for Hong Kong-Corlett 1992b;Dudgeon and Corlett 2004;Leven and Corlett 2004;Chung and Corlett 2006;for Singapore-Corlett 1988, 1992aTan et al 2007). In contrast, only single alien plant species, Syzygium jambos in Hong Kong (Leung et al 2009) and Clidemia hirta in Singapore (Teo et al 2003), have signiWcantly invaded native, closed-canopy forests.…”

“…Indeed, more than half the >20 alien bird species established in Hong Kong (including the islands and adjacent mainland) are found in forests and both their diversity and abundance is increasing (Leven and Corlett 2004;Kwok 2007;Leven pers. com.).…”

“…For example, two native species of murid rodents dominate 1 C semi-natural upland plant communities on Tai Mo Shan and elsewhere, while six additional species occur only as urban or agricultural commensals, and are presumed to be exotic (Chung and Corlett 2006). The birds, however, provide a striking exception to this pattern, with many of the introductions of the last few decades being conWned to closed woody vegetation-the precise opposite of other taxa (Leven and Corlett 2004). This appears to reXect the dominant mode of introduction-the release of cage birds by Buddhists-rather than any peculiarity of birds.…”

Exotic plant invasion in the highly degraded upland landscape of Hong Kong, China

Plant communities in the continental tropics have suVered less from exotic plant invasions than their oceanic island counterparts. Most studies have focused on nearpristine communities. By contrast, we examine the resistance of semi-natural continental plant communities in Hong Kong, which have been suVering from chronic and massive human impacts. We compiled a list of all naturalized non-native species recorded in Hong Kong and then sampled the plant communities for exotic species along roadsides, a stream through semi-natural vegetation, and in semi-natural vegetation away from both roads and streams on Tai Mo Shan, Hong Kong's highest peak (957 m). Similar surveys were repeated in other areas of Hong Kong. More than 162 naturalized exotic plant species have been recorded in Hong Kong. On Tai Mo Shan, 29 exotic species were recorded in roadside vegetation, with the diversity but not percentage cover declining signiWcantly with altitude. Fifteen exotic species were found along the stream, including two not found along the roadside. Only six exotic species were found away from roads and streams, all in unshaded areas disturbed by feral cattle. In all surveys, no exotics were found in closed woody vegetation or in open areas without feral cattle, except for one species. The shade-tolerant tropical Asian tree Syzygium jambos was found invading along some streamsides without anthropogenic disturbance. Despite centuries of massive human impacts, exotic plant invasions in Hong Kong are still largely conWned to habitats that suVer from chronic human disturbance. Feral cattle promote invasion where people are absent, but this problem still seems potentially reversible. Only Syzygium jambos is of possible current conservation concern.

“…Parrots, in general, are known to cause damage to crops in their native range (Long 1981;Jepson et al 2001), especially when they feed on young fruits (Leven & Corlett 2004). Red-breasted Parakeet in huge flocks are known to raid maize and rice fields in their native range (Long 1981), and have been known to damage up to 50% of the crops (Jepson et al 2001).…”

Sighting of Red-breasted Parakeet Psittacula alexandri (Linnaeus, 1758) (Psittaciformes: Psittaculidae) from Vellayani, Thiruvananthapuram, Kerala, India

Red-breasted Parakeet is one among the most widespread parakeets of the world. The ‘Near Threatened’ bird has been in pet trade for long and is already known as a feral bird from major cities in India. The biodiversity of India has been threatened by many alien invasive species and some have been of a serious threat to native species pushing them to extinction. Though Red-breasted Parakeet with a limited population in many of the cities is of no immediate threat, an increase in population can be of serious threat to native bird species. In this paper, we report the new sighting of Red-breasted Parakeet from Vellayani-Punjakari wetlands, Thiruvananthapuram, Kerala and discuss the possible threats this particular species can impart to the native bird diversity.
