Term Ecological diversity
Definition

The internal variety within an ecosystem or community of plants, animals and/or micro-organisms. It can refer to variety within forests, deserts, oceans, pastures, water currents, lakes or other biological communities that interact among themselves and with their non-living environments.

Ecosystem diversity is the most difficult type of diversity to assess since there are many ways it can be classified. The scale of an ecosystem is the most important factor in the measurement of the complex variety of ecosystems, as it can range from biomes at a global level to micro-habitats at scales of a few square meters. Likewise, it is often unclear where an ecosystem ends (a pine forest, for example) and where another starts (a mixed forest of pines and hardwoods) because there are areas of transition between them. However by having a clear definition, which depends on the author, one can measure the diversity of biomes, eco-regions, ecological systems, microhabitats or other levels in a given region at any given time.

The Dominican Republic has a high diversity of ecosystems, ranging from the pine forests of Duarte’s Peak at 3,087 meters, the highest peak of all the Antillean mountains, to the dry forests of the south, the coastal mangroves of the Samaná bay and the coral reefs of Las Aguilas bay. An interesting ecosystem is Lago Enriquillo, a natural reservoir of fresh water which is located more than 40 meters below sea level.
