Alwar, April 23 -- Tourists in the buffer zone of the Sariska Tiger Reserve, Alwar distrcit, on Wednesday were treated to a rare and close encounter with tigress ST-19 and her cubs, said forest department officials. The increased sightings in the buffer zone are due to improved prey availability and sufficient water sources, said the officials. Measures such as conservation of water bodies and habitat management have contributed to the movement of tigers beyond core areas, they added. "Efforts to conserve natural water sources, create new water bodies, and maintain a safe habitat for wildlife have yielded visible results. As a result, tigers are now venturing beyond the core areas and are being spotted more frequently in buffer zones," said an official. Wildlife activity in Sariska Tiger Reserve has surged in recent days, creating a wave of excitement among tourists and wildlife enthusiasts. The spotlight is firmly on tigress ST-19, who has been frequently sighted along with her four cubs, emerging as the biggest attraction in the reserve. Sariska's tiger population revival began in September, 2008, when tigers were relocated from Ranthambore National Park after the reserve had lost its entire tiger population. Through sustained conservation efforts, close monitoring, and strategic planning, the tiger count in Sariska has now crossed 50, including cubs-marking a significant success story in wildlife conservation. The presence of ST-19 and her cubs has brought renewed attention to the reserve, officials added....
