No
Family
CHAMAELEONIDAE
This species is extremely rare in the wild and is known to be exploited, utilised or traded. The localities of remaining populations need to be protected to avoid any further exploitation, which is likely to drive it to extinction.
Exploitation extent
Significant - wild individuals of the species are known to be exploited, collected, traded or utilized in a targeted manner, and utilisation is widespread, affects the majority of wild populations and/or is causing rapid decline of the wild population.
Justification and references

This species is listed on CITES Appendix II, with more than 100 individuals exported since 2015 (UNEP-WCMC 2018). The species has an overall distribution area of ca. 3,00km2 but the fragmented nature of the habitat results in very localised small subpopulations (Tolley 2017, Tolley In press). Targeted collections are easy to carry out, as the habitat is highly degraded and fragmented, making chameleons easy to spot in the vegetation.

Population vulnerability
Population is vulnerable: size is <= 2500 mature individuals OR the number of known subpopulations is <= 5 OR range is <= 100km2 OR species at risk of localised extinctions
Justification and references

The small local subpopulations in habitat fragments are vulnerable to over-collection and could result in local extinctions. Recolonisation potential is low given that this species is a habitat specialist (da Silva & Tolley 2013, da Silva et al 2014, da Silva & Tolley 2017) and would not easily disperse between fragments.

Targeted demographics
Mature (breeding) individuals are killed, significantly weakened or are permanently removed from the wild, OR immature individuals are targeted and this significantly impacts mature (breeding) individuals.
Justification and references

There is permanent removal from the wild of this species (UNEP-WCMC 2018).

Regeneration potential
This species has a slow population growth rate, or the growth rate varies depending on habitat, and there is a poor chance the wild populations will recover from exploitation OR a collector might feasibly harvest the entire extant population removing the chance of subsequent recruitment.
Justification and references

This species is viviparous, and other species n the genus give birth to clutches of 5-15 offspring annually (Tolley & Burger 2007). Given their life history, it is likely that the species could recover from limited permanent removals, although their habitat is highly fragmented and recolonsation potential is limited, given they are habitat specialists (da Silva & Tolley 2013). A collector could feasibly harvest and entire subpopulation in a fragment, resulting in local extinctions in these small fragments. Given the limited dispersal ability across unsuitable habitat, recolonisation potential will be low and local extinctions would persist.
