Kathmandu, July 29: Nepal is celebrating the 17th World Tiger Day today, reaffirming its commitment to protecting the endangered species and raising global awareness about tiger conservation. World Tiger Day is observed every year on July 29 following a decision made at the St Petersburg Tiger Summit in Russia in 2010 under the Global Tiger Initiative. Although the official report has yet to be released, preliminary assessments suggest the country’s tiger population has increased further. Conservation officials expect Nepal’s wild tiger population to reach around 400. The global wild tiger population is currently estimated at around 5,500.
