Les Todiers covers 845 ha inside the historic park Citadelle, Sans souci, Ramiers, overlooking from its steep slopes the towns of Milot, Grande Rivière du Nord and Dondon. It lies in the Northern Department at latitude 19°61'N and longitude 72°21'W on rugged karst terrain made of early Eocene (50 myBP) limestones outcroppings that serve as a refuge for many upland and lowland birds (600 to 900 m elevation). It is adjacent to the tourist area associated with this historic park and the Plaine du Nord, one of the most important agricultural areas in Haiti. The town of Milot is inhabited by a majority of tourist guides and craftmen, whereas in the two other towns farmers represent the majority. Every year for Good Friday, thousands of young visit the monuments as a good luck pilgrimage.
The avifauna, although poorly studied is rich and diverse. It includes 15 endemics (Species such as the Narrow-billed Tody (Todus angustirostris) and the Broad-billed Tody (T. subulatus), which are allopatric in most of Haïti, occur together in the zone between 500 to 850 m elevetion in this region. Parakeets, which are usually found in lowland areas, occur occasionally with parrots above 500 m elevation. Night birds had not been surveyed.
Non-bird biodiversity: The herpetofauna of the region represents a significant part of the fauna of the island. Some reptiles such as Anolis eugenegrahami, Sphaerodactylus lazelli and Anolis christophei first found in the La Citadelle region as well as frogs such as Eleutherodactylus poolei and Eleutherodactylus schmidti limbensis.
