Site description (2001 baseline)
The Dilia or Dillia de Lagané is a linear depression stretching some 200 km north-west from Nguigmi, at the edge of the former extent of Lake Chad, to the southern end of the Termit Massif. The depression is probably a graben which historically carried water to Lake Chad during periods when the climate was wetter. The Dilia lies in a very sparsely populated area of low rainfall (annual average less than 200 mm for the period 1961–1990). Vegetation is sparse; much of the Dilia de Lagané lies in the northern Sahelian semi-desert grassland and shrubland zone, while the southern quarter falls within the Sahelian Acacia wooded grassland and deciduous woodland zone. Land-use is probably restricted to nomadic and/or transhumance livestock-rearing.

Key biodiversity
See Box and Table 2 for key species. What information there is dates from 1975 when Neotis nuba was found breeding in August (three nests with eggs). Ardeotis arabs was also recorded on numerous occasions and Circus macrourus was seen once. Of the Sahel biome species, Caprimulgus eximius has been reported only from this site. In addition, three Sahara–Sindian biome and one Sudan–Guinea Savanna biome species also occur (see Table 2).

Non-bird biodiversity: None known to BirdLife International.
