Klong Khao Daeng Klong Khao Daeng is a stream running deep into mangrove forests at one end and at its mouth freshwater and seawater collide. The mangroves consist of the samae thalay (grey mangrove), kongkang bai lek (true mangrove), kongkang bai yai (red mangrove), and chakhram (herbaceous seepweed). Climate The temperature in winter (between October - February) ranges from 18˚C to 25˚C. The temperature in summer (between March - May) ranges from 23˚C to 32˚C. The temperature in the monsoon season (between June - September) ranges from 20˚C to 30˚C. Fauna The park is home to a variety of birds, including the common kingfisher, the black-capped kingfisher, the collared kingfisher, the little heron, the little egret, and the Javan pond-heron. Wildlife found in the mangroves includes pla teen ([mudskippers]), pu kam dab (fiddler crabs), ling samae (the crab-eating macaque), collared kingfisher (nok kin pieo), snapping shrimp (kung deed khan), mud creeper (hoi khika), and oysters (hoi nangrom).
