초록
The cultivation of biomass crops is now global demand for decreasing emissions of carbon dioxide (CO2) from fossil fuel. Miscanthusspecies have been studied as a suitable crop for biomass production, due to its characteristics of fast growth and high biomass. InKorea, Miscanthus species have gained wide attention as an option for biomass production alternative to fossil fuels, recently. Newstrain of giant Miscanthus has been developed and two large trial sites for the giant Miscanthus production were built in the lowerreaches of the Geum River. To evaluate the ecological influence of the giant Miscanthus as an bioenergy crop for the future, weinvestigated the impact of the construction of the giant Miscanthus production fields on the biota and also compared it with biota inpaddy fields near the study sites. The biota including plants, amphibians, reptiles, mammals, avifauna, insects, and bugs wasinvestigated. The plant diversity of the giant Miscanthus production fields was poorer than the paddy fields because the high heightof the giant Miscanthus might hinder the growth of other plants. However, the giant Miscanthus production fields serves habitat toanimals, leading to rich diversity of animals including avifauna, insects, and bugs. The rich diversity of the animals in the giantMiscanthus production fields coincides with the fact that the giant Miscanthus was grown without any pesticide, herbicide, andfertilizer. This study showed that the giant Miscanthus can influence on biota and further long term study is needed to elucidate theinteraction between the diversity of biota and the giant Miscanthus.
Abstract
The cultivation of biomass crops is now global demand for decreasing emissions of carbon dioxide (CO2) from fossil fuel. Miscanthusspecies have been studied as a suitable crop for biomass production, due to its characteristics of fast growth and high biomass. InKorea, Miscanthus species have gained wide attention as an option for biomass production alternative to fossil fuels, recently. Newstrain of giant Miscanthus has been developed and two large trial sites for the giant Miscanthus production were built in the lowerreaches of the Geum River. To evaluate the ecological influence of the giant Miscanthus as an bioenergy crop for the future, weinvestigated the impact of the construction of the giant Miscanthus production fields on the biota and also compared it with biota inpaddy fields near the study sites. The biota including plants, amphibians, reptiles, mammals, avifauna, insects, and bugs wasinvestigated. The plant diversity of the giant Miscanthus production fields was poorer than the paddy fields because the high heightof the giant Miscanthus might hinder the growth of other plants. However, the giant Miscanthus production fields serves habitat toanimals, leading to rich diversity of animals including avifauna, insects, and bugs. The rich diversity of the animals in the giantMiscanthus production fields coincides with the fact that the giant Miscanthus was grown without any pesticide, herbicide, andfertilizer. This study showed that the giant Miscanthus can influence on biota and further long term study is needed to elucidate theinteraction between the diversity of biota and the giant Miscanthus.
