From the IUCN Red List Species Account:

 

Range Description

This species is currently known from two localities in eastern Madagascar: the island of Nosy Boraha and the mainland coast north of Toamasina, at elevations between 10-20 m asl (Vences et al. 2010). Surveys in nearby areas only recorded Blommersia blommersae, which is also known to occupy the habitat to the north and south of the mapped region, suggesting that Blommersia dejongi is probably restricted to the narrow stretch of low elevations along the coast and that current known localities span the largest part of the species' distribution (Vences et al. 2010), thus its extent of occurrence (EOO) has been estimated at 4,953 km2.

Habitat and Ecology

This species appears to be a generalist, adaptable to living in lowland forest and severely degraded habitats such as scrubland, paddy fields, and plantations (Vences et al. 2010). It is presumed to reproduce by larval development.

Population

Available information suggests this species is common where it is found and, due to its adaptability to degraded habitats, its population is unlikely to be decreasing (Vences et al. 2010).

Population Trend

stable

Major Threats

Due to its adaptability to degraded habitats there are no recognized threats to this species.

Conservation Actions

Conservation Actions
Although this species has a limited coastal distribution and is only known from two localities, there are no recognised threats to this species. 

Research Needed
This includes studies into population size, distribution and trends, life history and ecology, and also monitoring of population trends to confirm that it is not decreasing.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern as, despite the limited coastal distribution of this species, its adaptability to severely degraded habitats indicates that there is no immediate threat to its survival.
