Dodo, Wawangningrum H. 2018. Caring wildlings methods for ex situ conservation: red balau (Shorea guiso (Blanco)Blume). Pros Sem Nas Masy Biodiv Indon 4: 139-143. Shorea guiso (Blanco) Blume of the family Dipterocarpaceae is one of the mostimportant hardwood species used in general construction of houses. It is native in Cambodia, Vietnam, Thailand, Peninsular Malaysia,Sumatra, Borneo, and the Philippines, scattered in lowland forest, but Critically Endangered A1cd ver 2.3, so it must be saved. Ex situconservation is an effective strategy for saving the plant from extinction. One way is to move the wildlings from in situ to ex situ areathrough exploration activities. Problems in displacement of wildlings is very low survival rates, the cause is too long kept. The studyaims to obtain the best method so that wildlings can survive for a long time. Experiments using completely randomized design withtreatments: the type of growing medias (moss, leaf litter, tissue paper, and without media), cutting leaves (50% and 0%), and storingtimes (1, 2, 3 weeks). Each experimental unit contains 10 wildlings of S. guiso with three replications. The results showed that theaverage of survival rate on two months after planting was 77.08% to which stored one week, 38.33% of the stored two weeks, and26.67% of the stored three weeks. So, the wildlings should not be stored for too long. The best treatment is reduced by 50% of the leaf,without media, and covered with a plastic bag.
