This recently described species has a very small range in which habitat degradation is likely to be causing the population to decline. However, it is not known to be severely fragmented or restricted to few locations, therefore the species is classified as Near Threatened. Further information may lead to the species being uplisted in the future.
|Previously published Red List assessments:|
|Range Description:||Zosterops somadikartai is native to the Togian Islands, Indonesia. Its population size has not been quantified owing to its recent discovery, but is has been described as uncommon and localised, and the population is suspected to be declining owing to habitat destruction (del Hoyo et al. 2008, Indrawan et al. 2008).|

|Population:||The population size of this species has not been quantified but is has been described as uncommon and localised.|
Trend Justification: Population trends are not available for this species owing to its recent discovery, however the population is suspected to be declining owing to ongoing habitat loss (Indrawan et al. 2008).
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species has been recorded in low bushes near mangroves, gardens, coconut groves, secondary shrub, and in logged-over forest from sea level to 100 m (del Hoyo et al. 2008, Indrawan et al. 2008, D. Indrawan in litt. 2010). It typically roosts in shrubs which are 5-15 m tall. Its diet is comprised of insects, including caterpillars, which are gleaned from branches and beneath leaves. It forages in pairs or small flocks of up to five individuals, often visiting dense, low shrubs (del Hoyo et al. 2008, Indrawan et al. 2008).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||3.5|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||The extent and quality of suitable habitat on the Togian Islands is likely to be decreasing owing to conversion and overexploitation of resources (del Hoyo et al. 2008, Indrawan et al. 2008). In the past mining (for minerals, especially prospecting for gold) has caused habitat loss and degradation and it is suspected that further mining activities may take place in the future, possibly under the guise of applications to develop palm oil plantations (M. Indrawan in litt. 2016). Oil palm proposals tabled in 2012-2013 were halted through advocacy which led to a 2014 local parliamentary decision to prevent palm oil development on the island altogether, however there remains the threat that large-scale forest conversion may return given the isolation of the islands and concentration of political power in a single district head (M. Indrawan in litt. 2016). Conflicts among the residents over guiding and lodging opportunities arising from unregulated tourism may undermine efforts to maintain consistent support for conservation, and tourism infrastructure may encroach on forested areas or lead to exploitation for building materials (M. Indrawan in litt. 2016).|
Conservation Actions Underway
The Togian Islands have been declared a national park (del Hoyo et al. 2008). A team of local residents are promoting the adoption of sustainable agriculture, with relevant stakeholders including local communities and district government engaged to build capacity in local communities to achieve better and more sustainable tenure (Indrawan et al. 2013). Negotiations to secure community-conserved areas were constrained by difficulties in outreach due to the geographic isolation of many communities, but a local group mission to protect local culture and nature through revitalisation of indigenous values has been formed (M. Indrawan in litt. 2016). Conservation Actions Proposed
Assess the population size and establish a monitoring programme to establish trends. Establish ecological requirements. Identify and assess threats. Provide support to local communities for efforts to delimit indigenous territory under forest cover, and for forest restoration and use of non-timber forest products (Indrawan et al. 2013). Work towards the establishment of appropriately sized and situated protected areas, through community-based forest protection (Indrawan et al. 2010, 2013), that support viable populations of this and other threatened species known to occur on the islands. Continue to work with local communities to promote the conservation of this species.
