The rare and endangered siroy lily is the state flower of Manipur. Shirui Hill is one of the only two places in Manipur that the Siroy lily is found, that too only for a couple of months following mid-May every year. Since the year 2000, the Shiroi Youth Club has been tirelessly protecting the site. Among the steps that the youth club members took to protect the lilies were: checking the visitors, guarding the site as volunteers, putting up barbed-wire fencing around the site etc. The hard work of the Shiroi Youth Club has borne fruit and after a gap of nearly 11 years widespread flowering of the lily can be seen again. The greatest threat to this rare lily is from the large influx of tourists.
