Sanford's White-eye Zosterops lacertosus



Justification

Justification of Red List category
This species has a restricted range and there is an ongoing decline in the area and quality of its habitat as a result of commercial logging. It is therefore classified as Near Threatened.

Population justification
The population size of this species has not been quantified, but it is described as fairly common (Dutson 2011, Pierce 2014).

Trend justification
Although logging is now ongoing, the population trend of this species is considered unknown given its occurrence in degraded forest (Dutson 2011) and the relatively slow rate of forest loss. Remote sensing data (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein) indicate that in the ten years to 2020, forest loss in this species' range has been equivalent to c.1-2%. The rate of forest loss appears to have significantly increased since c.2017 (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein), reaching 0.25% in 2017 due to the initiation of commercial logging on the island at a significant scale (Hunt 2019, J. Wood in litt. 2020).

Distribution and population

This species is endemic to Nendo in the Santa Cruz islands of the Solomon Islands.

Ecology

It is a forest species, favouring primary forest but also occurring in degraded and secondary forests with some remaining large trees (Dutson 2011).

Threats

The main threat to this species is forest loss in its range (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Commercial logging is now well established on Nendo (Hunt 2019, J. Wood in litt. 2022). Mining operations may result in further habitat destruction (J. Wood in litt 2022).

Conservation actions

Conservation Actions Underway
None are known.

Conservation Actions Proposed
Regularly monitor the population at selected sites. Research its tolerance of logged and degraded forest. Protect significant areas of primary forest on Nendo. Support the islanders' ecoforestry schemes.
