Trioceros laterispinis has been assessed as Vulnerable as it has an estimated extent of occurrence of approximately 11,500 km2, only occurs on one mountain range and is threatened by habitat loss due to agricultural development. The species occurs in an increasingly fragmented environment and there are no conservation measures in place to protect either the species or the habitat it occurs in. The species is also harvested for international trade, although this is regulated by CITES.
|Range Description:||This species is endemic to the Udzungwa region of the Eastern Arc Mountains, Tanzania. At present it is known only from the vicinity of Mufindi and Kigogo (Spawls et al. 2002). It has an estimated distribution of 11,529 km2.|

|Population:||There is no population information available for this species.|
|Habitat and Ecology:||
This arboreal species is found in forest and fairly dense woodland, and probably prefers thicket and understorey to big forest trees. It is not thought to be found in open savanna woodland.
This species gives birth to live young (Spawls et al. 2002).
This species is threatened by habitat loss and degradation. Newmark (1998) reports that the Udzungwa Mountains have lost 76% of their original forest cover principally to agricultural and plantation land, with only 1,960 km2 of natural forest remaining. Of this remaining forest, just 389 km2 is closed forest, as estimated from landsat imagery for the period 1994-96. Furthermore, it is a highly fragmented landscape, consisting of 26 fragments.
Along with other chamaeleon species in East Africa, this species is collected from the wild for the international pet trade (CITES 2005).
|Conservation Actions:||This species is listed on CITES Appendix II (CITES 2007). It occurs in a habitat which is suffering from high rates of destruction, therefore conservation measures are required to prevent further habitat loss and fragmentation of the landscape, such as the establishment and management of protected areas. Improved surveys are necessary to obtain better estimates of both the species' abundance in areas where legal collections occur, and its area of occupancy, which may be much smaller than the estimated extent of occurrence due to conversion of forest to agricultural land.|
