Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Amphibia Anura Hylidae

Scientific Name: Hyla japonica
Species Authority: Günther, 1859
Common Name(s):
English Japanese Tree Frog
Hyla arborea Günther, 1859 ssp. japonica
Hyla stepheni Boulenger, 1887
Hyla ussuriensis Nikolsky, 1918
Taxonomic Notes: Hyla japonica is a member of the Hyla arborea complex. A number of authors consider H. japonica to be a subspecies of H. arborea, but biochemical and morphological differences between these two forms confirm the specific rank of H. japonica. Fei (1999) considered H. ussuriensis from northern China, the Korean Peninsula, eastern Russia and Mongolia to be a separate species from H. japonica on Japan. Here we consider H. ussuriensis to be a synonym of H. japonica pending further taxonomic work on this complex.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Sergius Kuzmin, Irina Maslova, Masafumi Matsui, Fei Liang, Yoshio Kaneko
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits mixed and deciduous broadleaved forests, forest steppes, bush lands, meadows, swamps, paddy fields, ponds, and the surrounding vegetation. It is often found along the banks of rivers, streams, and lakes. Spawning and larval development takes place in stagnant ponds, puddles, oxbow lakes, flooded quarries, and lakes with dense herbaceous vegetation. The eggs are sometimes deposited in river and stream pools. The species tolerates some degree of habitat modification, and may even be found in large cities.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The threats to this species are not well known, but are presumed to include general habitat loss, (often from changes in land use such as conversion of paddy fields to vegetable farming), pollution and prolonged drought in arid areas.

Conservation Actions [top]

Conservation Actions: The range of this species overlaps with many protected areas. It is listed in the Red Data Books of Buryatia and the Evreiskaya Autonomous Province of Russia.
