India's threatened tiger population, once on the verge of extinction, has increased by 20 percent in the last four years. As the Albany Times Union reports, wildlife officials and naturalists report most tigresses in the central India reserves either have or will have their cubs soon. This information makes 2012 a good year for eco-travel to India.

"These days in the course of a 10-day tiger safari people may see five, 10 or more tigers, and often with close-up views," says Dr. Will Weber of Journey's International. "This is partially due to increasing skill and knowledge of the guides, but there are more tigers."

In the past, viewing a tiger was rare. In 2010, India's Bengal tiger was classified as endangered by the International Union for Conservation of Nature (IUCN). Now, the total population of Bengal tigers is probably still under 2,000. A nationwide census carried out in 2011 estimated a total of 1,706 up from 1,411 from the previous count in 2007.

"If you know where, how and when to look, you will certainly find pleasant surprises," says Avi Sakhrel, noted Indian birder, naturalist and wildlife guide who leads India wildlife tours. Sakhrel notes, "The Indian conservation community is very pleased to see positive results of efforts to save our wildlife. Even some of the lesser known parks now offer regular big cat sightings."
