Brookesia desperata has not yet been classified by the IUCN, but all Brookesia species are listed on Appendix II of CITES (2) (3).

Brookesia desperata belongs to the leaf chameleon genus Brookesia, species of which are also known as the dwarf chameleons. This species was first discovered in 2007 in northern Madagascar, along with three other new leaf chameleon species, and all were formally described in 2012 (1).

The head, back and tail of the miniature Brookesia desperata are light grey, in contrast to the sides of the body which vary between beige, brown and dark brown. A darkened colouration, along with the presence of dark brown spots on the sides and almost entirely dark brown limbs, is believed to be a stress colouration in this species. Brookesia desperata is able to change colour rapidly in response to stress, a trait characteristic of most chameleons. Variation in the colour of this species has been observed, with some individuals having an almost entirely beige-coloured body, a slightly lighter forehead and a stripe down the back.

Lines of pointed tubercles run down the body, on either side of the spine, and there are also distinct spines on each side of the tail. This species is set apart from other Brookesia species by three enlarged tubercles on its head. Like other Brookesia species, Brookesia desperata is distinguished from other chameleons by its short, non-prehensile tail (1). 

Brookesia desperata is known only from the Forêt d’Ambre Special Reserve in Antsiranana Province, northern Madagascar (1).

Brookesia desperata is restricted to the disturbed rainforest of the Forêt d’Ambre Special Reserve (1). This reserve is subject to distinct seasonal variation, with a fairly long dry season followed by a wet season that runs from December until April each year. Both lowland rainforest and dry deciduous forest are present within the reserve, and Brookesia desperata is typically found at elevations of between 400 and 500 metres above sea level (4). This species was also found on banana plants at the edge of forest clearings (1).

Described as an arboreal species (4), Brookesia desperata has been found resting on small branches or leaves at night, approximately 5 to 100 centimetres above ground. This species appeared to be present in high abundance within its extremely restricted habitat (1). There is currently no information available on the diet of Brookesia desperata.

Although relatively little is known on the reproductive behaviour of Brookesia desperata, one female specimen laid two large eggs (1).

Like other members of the Brookesia genus, Brookesia desperata may be representing a case of island dwarfism, a phenomenon whereby a species adapts over time to being restricted to a particular habitat, for example an island, by becoming smaller (5).

Despite Brookesia desperata’s presence within a nature reserve, the future of this species is in jeopardy (1). The Forêt d’Ambre Special Reserve was established in 1958, and is identified as a site of high conservation importance for the region’s endemic amphibian and reptile species. At present the reserve is subject to immediate threat from habitat clearance for the cultivation of banana, coffee, rice, maize and papaya. Forest clearance for charcoal and timber production, quarrying and cattle grazing is also destroying the integrity of this habitat (4).

Forest clearance results in habitat fragmentation, which can have severe consequences for reptile and amphibian species, potentially causing local or even complete species extinction (4). 

There are no specific conservation measures currently in place for Brookesia desperata. The establishment of the Forêt d’Ambre as a special reserve appears to have been relatively ineffective in protecting the area’s tropical biodiversity (1), and it is abundantly clear that further conservation management is needed. Immediate action has been suggested in the form of training forest wardens to patrol the area, monitoring and restricting forest clearance, and developing small-scale ecotourism as a more sustainable use of the park (4).

Scientists also highlight the importance of raising local awareness of environmental issues and sustainable agricultural practice in the region (4).
