Conservation Notes
This species has been assessed as Least Concern by the IUCN Red List of Threatened Species and is included on Appendix II of CITES and EU Annex B. There is no annual export quota for this species, however they are commonly mislabeled and exported as Calumma boettgeri, which specimens of this species were previously thought to represent until recent revisions of this group (Prötzel et al. 2015). This species occurs largely within the protected area of Montagne d'Ambre National Park, as well as other nearby areas.

Captive Propagation
In captivity, this species has hatched after 11-15 months incubation with seasonal and daily temperature fluctuations (Anderson, pers. obs.). Clutches laid in February and June hatched the following May. In the winter months incubation temperatures got down to the high 50s/low 60s Fahrenheit at night and into the high 60s/low 70s Fahrenheit during the day. In the summer months incubation temperatures got into the high 60s Fahrenheit at night and mid/high 70s Fahrenheit during the day. Hatching was likely synced between clutches as a result of the winter temperature drops producing a diapause and incubation period would likely have been reduced with an earlier onset of diapause (being laid in February and June, they did not enter a proper diapause period for 6-10 months).
Distribution
Madagascar
Calumma linotum is known to occur in northern Madagascar in and around Montagne d'Ambre and Joffreville, as well as from the Andampy area of the Tsaratanana massif (Prötzel et al. 2015). Further, records of Calumma boettgeri from the area surrounding Antsiranana (Diego Suarez) are believed to belong to C. linotum (Prötzel et al. 2015).
