Forest classification according to the predominant vegetation



Conifer forest

Type of forest where conifers (pines) are the predominant species, with more than 75% of crown cover. In this country, the predominant species is the native pine (Pinus occidentalis). The native pine forests are found mostly in highland areas, at elevations above 2,000 meters above sea level in the Cordillera Central, Sierra de Bahoruco and the northern slope of the Sierra de Neyba.

Broadleaf forest

Made up of broad-leaved species and, in some cases, mixed with pine species. They lie at elevations between 800 and 3,085 meters above sea level. The largest portion of this forest is located in the Cordillera Central, at elevations of over 2,000 meters above sea level, which is largest forest in the country.

Dry forest

The majority of dry forests are secondary forests. They are made up of semi deciduous tree species that lose their leaves sometime during the year. They thrive at elevations below 500 meters, and are located mostly in lowland areas, both in the south-southwest and the northwest of the country.

Wetland forest

There are two types: brackish wetlands forests (permanent and temporary) and fresh water forests. The brackish ones are located on the shores of lakes and lagoons where dissolved salts can be found (Laguna Limon, Lake Enriquillo), and in the coastal areas. They are located at elevations under 20 meters above sea level and at temperatures averaging 20 to 32°C. The fresh water wetland forests are located in Bajo Yuna, and are found at elevations under 20 meters above sea level and temperatures averaging 28°C.

All of the above classifications have contributed to the understanding and study of Dominican vegetation, especially the Hager and Zanoni classification system, which was published in 1993 in the Moscosoa journal of the national Botanical Garden, and has been used as a reference for plant classification in diverse flower studies in the country.
