Site description Extent of this site: consists of Big and Small Cat Islets. Cat Islets are in the southwestern seas of the Penghu Archipelago; they are 50 km to Makung, 20 km northwest of Chimei Islet; and 25 km west-southwest of Wangan Islet. The peak of Big Cat Islet, in the center of the islet, is 79 m in elevation. It is also the highest peak of the Penghu Archipelago. Small Cat Islet is 100 m to the southeast of Big Cat Islet, with a peak of 50 m. Both islets are named after their cat-like landforms. Surrounded by steep rocky cliffs, the islets are difficult for humans to climb up on. Totally 19 species in 12 families of plants have been recorded here. Chenopodium virgatum is the dominant ground cover on both Big and Small Cat Islets in summer; Silky-haired Crab Grass Digitaria serricea and Formosan Peacock-plume Chloris formosana are the dominant species in winter. The major bird species in Cat Islets are Common Noddy and Bridled Tern, which account for over 95% of all birds.
