Bird estimates may be skewed by floods

A biodiversity survey is under way in Punjab, covering the province's wildlife, flora, and fauna under the International Union for Conservation of Nature's (IUCN) National Survey Programme.

After completing assessments of terrestrial and aquatic reptiles, experts say that nearly 90 per cent of the flora survey has also been finalised, while the migratory bird census is expected to begin on October 21.

However, biologists warn that the recent floods could distort bird population estimates due to significant ecological disruptions across aquatic and terrestrial habitats.

According to Asim Jamal , National Manager of the IUCN Survey Project, four of the five ecological zones in Punjab have been fully surveyed so far. "Reptile surveys were conducted during the monsoon season when most species emerge from underground habitats," he explained. "The flora assessment is almost complete, and the bird survey is scheduled for the third week of October."

Jamal cautioned that the floods had disturbed migratory bird habitats, complicating efforts to record accurate species counts. "The first survey will provide baseline data, but to understand true trends in breeding, migration, and survival, at least three consecutive years of data collection are essential," he added.

Mudassar Hassan , Director of the Punjab Wildlife Survey Programme, said the project will conclude by June 30 next year.

"This is the first time a province-wide, scientifically structured wildlife and flora survey is being conducted using advanced equipment," he said.
