KATHMANDU, JANUARY 14
The latest census of aquatic birds in the wetlands and lakes of the Pokhara Valley has recorded an increase in overall bird numbers but a decline in species diversity, raising concerns among conservationists.
The census, jointly conducted by Tiger Mountain Pokhara Lodge and the Pokhara Birds Society, found that the total population of aquatic birds increased by 10.2 percent compared to last year. However, the number of species declined by 13.2 percent, according to a press statement issued by Jhalak Chaudhary and Manashanta Ghimire, regional coordinators of the Asian Aquatic Birds Census in Pokhara.
The survey, which concluded on January 9, recorded a particularly sharp drop in species diversity in Phewa Lake, traditionally known for hosting the widest range of indigenous and migratory aquatic birds in the valley.
Both the population and diversity of aquatic birds have also declined significantly in Dipang, Gundre and Khaste lakes. The census revealed a 59 percent fall in bird numbers in Dipang Lake, a trend ornithologists described as alarming.
In contrast, Maidi Lake and Rupa Lake showed encouraging results, with increases in both bird population and species diversity, indicating more favourable habitats in these areas.
Ghimire stressed the need to replicate the conservation practices adopted in Rupa Lake across other wetlands in the valley. He also called for sustainable management, protection of bird habitats and stricter control of human encroachment to conserve aquatic bird populations.
