Ecological Succession on Grass Slopes seeded by the Rapid Stabilizing Method. I

Fundamental Study on the Slopes of Higashiyama Turnpike

Abstract

Roadside slope is one of the most important factors for the landscaping of roads. And it is important problem that we recognize the relation between ecological succession and roadside landscape developmet.
The author investigated the plant communities of that roadside slopes at Higashiyama turnpike in Kyoto, on which 5 species of grass seeds (shown in Table I-1) were sown by a spraying method about 7 years ago. Summed dominance ratio of each plot community is shown in Table II-1.
Productive structure and relative light are shown in Fig. II-2-6.
From these results, the progress and velocity of succession are considered to be different among the communities. The community of creeping red fescue has little changed for 7 years. On the other hand, various native vegitations have aready intruded upon the communities of orchard grass, Italian ryegrass (this species can not be found because of annual grass.), and perennial rye grass.
