| Outline of Final Research Achievements |
Bare land formation and fecal seed by grazing livestock were greatly related to increase of invasive foreign plants. In Toimisaki-pasture, high species diversity has the high stability and robustness against to invasion of foreign plants due to quick recovery of bare land by creeping genotypes of native plants. Bare lands did not formed during summer grazing but formed during winter grazing. Genotypes of native plants with high invasion and colonization ability in bare plants were discovered and it is thought that these novel genotypes have high resistance ability for invasive foreign plants.
