“…These environmental variables, known and established to cause variation in species data may include precipitation (Buot andOkitsu, 1999, Ohsawa 1995), temperature (Buot and Okitsu, 1999;Richards, 1952), humidity (Richards, 1952), soil conditions (Heryati et al, 2011b, Suzuki et al, 2002, microbial composition, natural disturbances particularly, typhoon, erosion and landslides and anthropogenic disturbance history (Heryati et al, 2011a;Muniandy et al, 2009;Hong et al, 1995;Osumi et al, 2003). However, more works and experiments have to be done in testing these variables on Mount Makiling.…”
