The purpose of this study is to fiure out the floral changes during three years after construction of the Youido Ecology Park. Yearly change of plant species composition, distributed at the research field, had been investigated for three years since 1996. To compare and investigate the changes of the establishment of the Ecology Park, we have analyzed the distribution characteristics of plant species, exotic naturalized species, and so on. The results obtained through this investigation are as follows; 1) Total numbers of plant species were 106, 170, 175, and 148, in the year of 1996, 1998 1999, and 2000, respectively. While the most of cultivated species before th establishment were decreased, the naturalized species such Phargmites communis Trin, and Artemisia selengensis Turcz. etc, were increased. 2) Forty three species of exotic naturalized species were investigated and were increased at the early stage of the establishment, but showed decreasing trend recently. 3) Sixty five species of introduced and planted species were investigated. Most of them were occurred at the first year after the establishment, but since 1999, there has been a significant decrease. 4) Sixty seven species among total 235 were verified as the wetland-adapted plants. The ratio to the total numbers were low, but the occupied area of a few species was expanded. Therefore, it indicates that monitoring on the physical environments of the Youido Ecology Park was urgently required.

Main attackers on pine seeds on the forest floor were investigated in Korea. Damage on pine cones begins in early stage of cone formation, especially by squirrel and Korean squirrel. The above animals left Kayak-like hulls of seed on rocks and fallen tree trunk. Field mice also left the same shape of Kayak-like hulls. But birds including doves and peasants left large shreds with longitudinal cracks or seed cup trace. Most of seeds on the leaf litters as well as under the fallen leaf were consumed by field mice and birds. Especially field mice found the seeds under fallen leaves and consumed all of them.

본 연구는 우리 나라 최초의 생태공원인 여의도샛강생태공원을 대상으로 자연생태계 모니터링을 통하여 생물서식환경 조성기법을 평가하고 관리방안을 제시하는 것을 목적으로 하였다. 모니터링은 생물서식환견으로서는 수환경과 토양환경을 분석하였고, 생물상 모니터링으로 식물상, 식물군집구조, 동물상으로 구분하였고, 동물상은 조류와 어류의 변화에 국한하여 고찰하였다. 구체적인 모니터링 내용은 식물상의 변화와 식물군집의 천이과정, 두 연못에 적용된 식생호안 공법별 식생피복룰과 발생식물상의 변화, 귀화식물의 발생 정도에 따른 귀화율의 비교이었으며 이를 기반으로 조류와 어류의 변화를 평가하였다.
