Spatial and temporal distribution of butterfly in highland and lowland forests of Johor

Johor is a fast developing state and if unchecked could lead to loss of biodiversity. Among insects, butterfly is an important bioindicator of environmental changes. For effective management purposes, a baseline data of butterfly is needed. Samplings were carried out in various forest types: Taman N...

Among insects, butterfly is an important bioindicator of environmental changes. For effective management purposes, a baseline data of butterfly is needed. Samplings were carried out in various forest types: Taman Negara Johor Endau Rompin (TNJER), a lowland forest (30 to 100 m above sea level (a.s.l.)) and Taman Negara Johor Gunung Ledang (TNJGL), a highland forest (400, 800 and 1200 m a.s.l.).
