Wangtakrai Park is situated in the foothills outside and to the south of Khao Yai National Park in Nakhon Nayok Province, Thailand. His Royal Highness Prince Chumbhot of Nagor Svarga and his wife, Mom Rajawongse Pantip Paribatra acquired a portion of this private landholding situated betweentwo major streams thatflow outof theKhao Yai National Park in 1952 and developed and expanded the property. The park was first opened to the public in 1960 with the vision to create a center for botanical education and ecotourism. Ecologically, Wangtakrai Park is regarded as a transition zone between the highland forest of Khao Yai National Park and the privately-owned lowland floodplains in Nakhon Nayok Province. This unique location supports higher species richness and abundance than in the lowlands affected by ongoing human activity, though is less rich than in the highland forests. The intermediate elevation also cre-ates a blend of plant communities and succession stages that provide a wide variety of food sources and shelter necessary for terrestrial and aquatic animals. Recently, a high volume of visitors has also recently led to environment degradation due to human activity. This highlights the need for visitor education programs to raise awareness of conservation and reduce their environmentalimpacts. To achievethefirststep of creating a database of natural resources that can support educational initiatives, a preliminary survey project titled “Species diversity of animals inhabiting in Wangtakrai Park”was conducted.This projectwas acollaborativeeffort involving the Chumbhot-Pantip Foundation, the National Science Museum Thailand and Mahidol University. The four papers gained by survey results are published in a special volume of theThai Specimen Journal and document surveys of terrestrial invertebrates such as ant and mollusk species, bat species, and catalogue the aquatic species together with their biological characteristics. The aquatic surveys were mainly focused on documenting fishes and mollusks.
