Another threat has been caused by the introduction of yellow crazy ants, which decrease habitat quality.

Even a minimal decline in habitat quality can have a significant impact on these birds.

The population seems be quite extremely sensitive to changes in habitat quality and quantity.

Excess soot from a nearby fire, however, might negatively affect habitat quality.

Oftentimes population density is used to measure habitat quality but it has been very controversial.

Major variables in habitat quality include average visual obstruction and browse biomass.

Local populations may disappear however due to declining habitat quality.

Survival rates vary by geographic region, exposure to trapping, habitat quality, and age.

Recent works have been undertaken to improve habitat quality and extend the range of the invertebrate.

Unconfirmed reports from the late 1980s suggest that the island, should habitat quality improve, would in time be recolonized by the species.
