  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.
According to INEGI (1995) the area has a population of 402 inhabitants, accounting for 1.54% of the total population of the municipality of Álamos, of this 226 are men and 176 women. This population is distributed in 31 locations, although only 6 of those locations contain 86.57% of the total population of the area as follows: Baboyahui with 29.1%, Choquincahui with 7.21%, Guamuchilito with 5.22%, Las Plomosas with 11.69%, Puerta de Mano with 5.97%, Sabinito Sur with 21.89% and Santa Barbara with 5.47%; the rest are small villages of one or two dwellings and some single-family ranches.
The protected area is located in the municipality of Álamos. Regarding the regime of the land tenure, there are 156 properties within the area: of these, 70.28% (111 sites) are privately owned, 18.8% are common land (9 properties), 9.92% are national land (22 sites) and 1 % (11 sites) are Federally zoned.

  Brief description   There is a case study on the high basin of the Cuchujaqui river, a proposal for comprehensive watershed management, and surveillance tours are conducted to detect illicit activities. In addition, three projects are underway and three other projects have already received authorization to collect and/or handle species. Ongoing projects are: 1) Monitoring of cats, 2) Conservation and genetics of the desert tortoise, 3) Ecology and current situation of parrots. Also, a diagnosis is being developed of the condition of vegetation and soil in cattle ranches in the protected area and a study of marketing of tourism activities of four production projects.
