3. CONSERVATION TARGET PRIORITIES

An ecoregional approach for conservation planning requires a clear identification of specific conservation targets, that encompass the biodiversity of each ecoregion. An analysis of the presence and viability of these targets within specific sites, becomes one of the main discriminators that is used to identify and select, an effective ecoregional site portfolio that can be used for the long term protection of its biodiversity.

3.1.1 STATE LEVEL BIOLOGICAL DIVERSITY CONSERVATION TARGETS

Knowledge of Mexico’s biodiversity is still incomplete, although important advances have so far been achieved. biodiversity and endemicity has mainly been recorded using political or very broad geographical boundaries and not at an ecoregional level. For this first target identification exercise gross biodiversity within political boundaries of Mexican States will be used as a surrogate for ecoregional diversity and endemicity.
