Abstract

In order to develop a habitat planning method for wetland birds, a case study was done in Michinoku National Government Park in Miyagi prefecture, northeastern Japan. Actual vegetation map (scale 1/2, 000) and point buffers of 395 recorded bird locations were overlaid using GIS. Three groups (guilds) of birds were identified by cluster analysis, and composition of the vegetation for each guild was classified by discriminant analysis. Then, birds' potential habitat map (distribution of suitable habitats for each guild) was drawn as grid map based on information of vegetation composition. Finally, two types of simulated habitat maps were drawn based on two vegetation change scenarios.
