|Scientific Name:||Calumma gastrotaenia (Boulenger, 1888)|
Chamaeleon gastrotaenia Boulenger, 1888
|Taxonomic Notes:||Calumma gastrotaenia is a species complex, and is in the process of being revised (F. Glaw pers. comm. January 2011).|
|Red List Category & Criteria:||Least Concern ver 3.1|

|Reviewer(s):||Bowles, P. & Tolley, K.|
Listed as Least Concern as the species is widely distributed in eastern Madagascar and does not approach the threshold for possible listing in a threatened category under criterion B. Although likely declining, it does occur in degraded habitats and so is not thought to be declining at a rate that would warrant consideration for listing the species under the A criterion. Once the taxonomy of this species complex is resolved, this chameleon will require reassessment and may warrant listing in a threatened category.
|Range Description:||This chameleon is endemic to Madagascar where it occurs at a range of sites in the east and southeast of the island (Glaw and Vences 2007), ranging from around Andringitra in the south to Maevetanana in the north. The chameleon has an estimated extent of occurrence of 87,861 km².|

Population estimates of the short-nosed chameleon from surveys in the austral summer include 23.7 ha-1 at Andranomay (Jenkins et al. 2003) and 10.5 ha-1 at Mantadia (Brady and Griffiths 1999). While this species is tolerant of a high degree of habitat degradation, it appears unable to withstand deforestation and may occur at reduced densities in degraded forest, and so the population is likely to be declining due to the loss of humid forest within its range. It is not expected to occur as a fragmentary population (R. Jenkins pers. comm. June 2011).
|Current Population Trend:||Unknown|
|Habitat and Ecology:|
This chameleon inhabits both intact and highly disturbed humid forest. In Andranomay this species occurred in higher densities in unburnt than burnt forest (Brady and Griffiths 1999). This species is also reported to be locally abundant alongside small rivers within humid forest (Jenkins et al. 2003).
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||This species is not exported from Madagascar.|
|Major Threat(s):||This species occurs in highly degraded humid forest and nearby plantations and is not currently severely threatened. Nevertheless, this arboreal lizard appears to always be associated with humid forest and the loss of this habitat to agriculture and logging will result in population declines.|
|Conservation Actions:||This species is present in a number of protected areas, including Parc National Mantadia, Analamazoatra Special Reserve and Parc National Ranomafana. Near Andasibe, it occurs in the private reserve Parc Mitsinjo. The taxonomy of this species complex is in need of resolution, and research is ongoing to clarify this.|
