“The Investigation of Current Status in Gaoping River”, held by The Seventh River Management Office of Water Resources Agency, MOEA, is a two-years project from 2005 to 2007, the main stream and its four branches were detailed investigated. The results of the investigation not only provide more complete biological and ecological data for future management of the whole Gaoping River basin, but also carry out the true goal of ecological engineering methods. The major achievements of this project were: habitat investigation, river biological composition, ecological resource database and Geographic Information Systems (GIS) on World Wide Web (WWW) querying system.

In the first year, it has been completed the investigation of stream status in main flow of Gaoping River and its two branches, Cishan River and Meinong River. In the second year, the investigation of stream status for the other two branches, Laonong River and Ailiao River, has also been done.

Gaoping River

In the aquatic ecosystem, we collected 66 species of fish, 21 species of shrimp/crab, 83 species of algae, 13 species of shell and 55 species of aquatic insect. There are 14 endemic fish species and three conservation fish species in the study area. There are also 6 exotic fish species.

In the terrestrial ecosystem, there are 131 species of bird, 21 species of mammal, 32 species of reptile, 19 species of amphibian, 140 species of butterfly and 39 species of alderfly. In general, most of the species are typical animals that represent the ecological status in this region.

A resource database based on GIS technology was compiled. In the database, various layers of abiotic and biotic factors were digitized. These maps include administration, topography, river, human development, water survey, pollution index and biological resources. A web-based query system was also established and installed. User can access these pages from remote computers.

Through the integrated data, we provided various recommendations on how to design and manage the river resources. environmental protection index and suggestions for the river management.
