The number of bar-headed geese coming to Pong Dam Wetland has been decreasing since the past three years. As per the animal waterfowl estimation completed by the Wildlife Department, this year, 29,443 bar-headed geese visited the Pong Dam Wetland area.
According to the data available from wildlife officials, there has been considerable reduction in the number of bar-headed geese coming to the Pong Dam.

DS Dadwal, DFO, Wildlife Department, Dharamsala, when asked about the reducing number of bar-headed geese in Pong Dam Wetland said high water level in the lake this year might be one on the reasons for that.
