Abstract
Green spaces at business sites potentially have important roles for biodiversity in urban ecosystems, where habitats of living organisms are greatly reduced and fragmented. Japan Business Initiative for Biodiversity (JBIB) has developed three tools consisting of the guideline that explains importance and methodology of land use for biodiversity, the land use score card that quantitatively evaluates land use, and the monitoring sheet, with which non-experts can conduct a biodiversity survey. Although these tools were developed based on ecological knowledge, it was necessary to separately evaluate whether a site with high land use score actually have high biodiversity, and how reliable the data obtained by a survey by non-experts with the monitoring sheet is. Here, we conducted biodiversity surveys by non-experts with the monitoring sheet and by experts at the same time and date at eight business sites and compared the data obtained by the two survey methods. As a result, there were positive correlations between the land use scores and α-diversity, and between the α-diversities and also the β-diversities of the non-expert and the expert surveys. These results, as far as for evaluating overall biotas by α-diversity and β-diversity, validate the tools to promote land use for biodiversity enhancement at business sites.
