Cambodia is covered with the deciduous dipterocarp forests that once spread across much of Indochina and Thailand. These forests were formerly home to the greatest aggregation of large mammals and water birds that have existed outside the savannas of Africa. These forests have largely disappeared from Thailand and Vietnam; currently, the Northern and Eastern Plains of Cambodia form the largest remaining contiguous block of this unique and critically-important habitat. Visiting several sites in Cambodia, we have a lot of chances to see both the rarest ibises (White-shouldered Ibis and Giant Ibis), as well as many endangered water bird species, such as Bengal Florican, Greater Adjutant, Milky Stork, Black-necked Stork and Sarus Crane.
