Biotope

Striving to renew the relationship between people and living things in urban areas

The Saisei-no-Mori urban biotope is field of research and development on natural regeneration techniques aimed at improving biodiversity in urban areas. It is also a recognition that we must not lose the connection between people and nature in urban areas, and a venue for the conceptualization and dissemination of regeneration techniques. Shimizu engages in experimental testing based on the theme of three types of regeneration—of natural ecosystems, resources, and living environments. We also use the biotope as a place for environmental education.

Types of Testing

Regeneration of Natural Ecosystems in Urban Areas

Ecosystem network evaluation
Greenery regeneration
Habitat status
Conservation of endangered species

Resource Regeneration and Recycling

Reuse of soil generated at the site
Floating island made of discarded tires
Water purification

Regeneration of Living Environment

Microclimate improvement
Green therapy
Rainwater runoff control

Facility Features

Date built:	April 2006
Area:	1,940 m² in total (land area: 1,060 m², water area: 650 m²）
Plant/ animal types:	Plants (106 tree species, 94 grass species) Animals (7 fish species, 3 shellfish species, 2 crustacean species, 3 amphibian species)
Vegetation foundation:	Reuse of soil generated at the site and nearby topsoil (soil seed bank) Undulating ground to mitigate the effect of human interference to animals
Zoning	Ecotones (transition belts) in which vegetation gradually changes from water zones to land zones were built, and compact arrangements ranging from water plants to waterside forests, grasslands, deciduous forests, evergreen forests, and other vegetation were planted to create various types of habitats.

Examples of Tests and Achievements

Biotope Monitoring to Verify the Improvement in Biodiversity (Ongoing)

Plants: Ascertained development of the species planted and those that emerged, and tree growth
Animals: Ascertained the status of species living in the biotope for species introduced (fish, shellfish, crustacean, amphibian species) and species that appeared (birds; dragonflies, butterflies and other insects; aquatic organisms)
