Introduction:

Oak (Quercus sp.) forests are scarcely represented in Mexico’s Protected Natural Areas, and are highly susceptible to deforestation.

Objective:

To assess the regional dynamics of deforestation and recovery, as well as the factors of change in land cover and use (CLCU) in the oak forest of the Tehuacán-Cuicatlán Region (TCR) which includes the Tehuacán-Cuicatlán Biosphere Reserve (TCBR) polygon and its zone of influence.

Materials and methods:

The dynamics of the CLCU was analyzed in two periods; these were before (1979-2001) and after (2001-2011) the TCBR decree issuing. The analysis of the factors consisted of two stages: logistic regression analysis from the spatial interpolation of the factors, and analysis of the municipal socioeconomic trends based on change rates.

Results and discussion:

The oak forest was deforested prior to the TCBR decree, with a -0.97 % annual change rate. Deforestation was associated with low-slope areas, close to localities with a larger male population. In contrast, in the post-decree period its recovery stood out (0.22 %), which was associated with high-slope and high-elevation areas and a decrease in the male population.

Conclusion:

The TCBR decree must not be thought as the main cause of change in the CLCU processes; however, an indirect influence from it should be accepted.
