A handout photo from WWF taken with a remote infra-red camera and released on May 9, 2011 shows a rare Sumatran tiger with a cub in images recorded in March and April 2011 in the forest of Bukit Tigapuluh wildlife reserve in Indonesia's eastern Sumatra.  Conservation group WWF Monday urged companies to drop plans to clear Indonesian forest areas where camera traps have captured footage of critically endangere Sumatran tigers and their cubs.
