Conservation Actions Proposed
Survey its breeding range in Japan and its wintering range in the Philippines. Establish a monitoring programme of its breeding and wintering populations. Study its home-range requirements using radio-telemetry. Protect and manage forests in its breeding and wintering grounds. Ensure official protection throughout its range and strengthen and enforce legislation to prevent the sale of this (and other threatened) species. Establish public-awareness programmes concerned with its conservation. Control and monitor invasive species where appropriate within its range.
Japanese night heron
The Japanese night heron (Gorsachius goisagi) is a species of night heron found in East Asia. It breeds in Japan, and winters in the Philippines and Indonesia. It is also seen in the spring and summer in Korea and the Russian Far East.
The Japanese night heron prefers dense, damp forest, in both its breeding and winter ranges. Common until the 1970s, this species is threatened by deforestation in its summer and winter ranges. Other documented threats include the introduction of the Siberian Weasel (Mustela sibirica) in its breeding range. The current population is estimated at less than 1,000 mature individuals.
