Our life has become convenient and comfortable with the change of times. However, when we observe our surrounding environment, we find that the rapid and large-scale modification of land use, the frequent movements of organisms from their original distribution areas, and other human activities for our comfort have been greatly changing the balance of regional ecosystems. As a result, rare organisms have decreased or been extinct while some very unfamiliar or familiar organisms have rapidly increased, which has brought a variety of effects on our lives. Center for Weed and Wildlife Management (CWWM) has been working to deal with the conflicts caused by human activities between us human beings and other living things in the nature, especially with those problems of weeds and wildlife, and contributes its achievements for the society.
