  General Description   The protected area of Sierra de Álamos – Río Cuchujaqui falls within the geographical provinces of the Western Sierra Madre and the Northwest Coastal Plain, consisting of an elevational gradient of vegetation, from the tropical deciduous forest (lowland deciduous) to the Sierra Madre evergreen forest (pine-oak forest). The Sierra de Álamos runs parallel to the coast of the Pacific Ocean and is crossed by numerous deep gullies that have been excavated by the rivers that flow into the Pacific; this is the case of the Cuchujaqui River, a tributary of the Rio Fuerte. It hosts a wealth of key species like puma (Puma concolor), jaguar (Panthera onca), ocelot (Leopardus pardalis) and kinkajous (Herpailurus yaguaroundi). There is an abundance of riparian forest of Taxodium mucronatum as well as a wide range of soils and geology. The region of Álamos is known for the confluence between the northern limits of many tropical species.
