Reviewer/s:

Bird, J., Butchart, S.

Contributor/s:

Justification:
This species has a small range and a moderately small, declining population. However, the range is not yet severely fragmented or restricted to few locations. For these reasons, the species is classified as Near Threatened.

Geographic Range [top]

Range Description:	Zoothera imbricata occurs in the Wet Zone of south-west Sri Lanka. Its population is thought to be moderately small as it is reportedly uncommon.
Countries:	Native: Sri Lanka

Population [top]

Population:	While the population size has not been properly estimated, owing to the species restricted range and declines in the area of available habitat in preceeding decades, the population is thought to be moderately small, hence it is perhaps best placed in the band 10,000-20,000 individuals.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	Resident in moist evergreen forest from 400 to 2,200 m within the 'Wet Zone' of Sri Lanka. A recent record suggests the species also inhabits forest in the 'Intermediate Zone'. Also recorded from plantations, copses and parks¹.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Deforestation leading to habitat fragmentation is the major threat to this species. Forest loss is driven by mining, clear-cutting, selective logging, subsistence use and agricultural encroachment.

Conservation Actions [top]

Conservation Actions:	Conservation Actions Underway No species specific conservation measures have been put in place for this species, but it has been recorded in the Sinharaja Rainforest Sanctuary and several other national parks and forest reserves. Furthermore, a moratorium was passed in 1990 to protect wet zone forests from logging, but encroachment continues. A survey of the biodiversity of 200 forest sites was carried out from 1991-1996. Conservation Actions Proposed Follow up on the first record of this species from the Intermediate Zone by conducting further survey work in remnant forest blocks in both the Wet Zone and Intermediate Zone that might support this species. Protect areas of lowland forest within the species's range. Enforce restrictions on logging and agricultural encroachment within wet zone forests. Generate density estimates to inform a revised population estimate for the species.
