The ecosystems in northeastern Mexico have become degraded, and, therefore, it has been necessary to develop strategies to restore them. The objectives of this study were to estimate the survival and composition of a reforestation with native species three years after its establishment, as well as to assess the floristic composition and ecological parameters of the Tamaulipan Thorny Scrub (MET) 11 years after its reconversion for hunting use. Based on their ecological parameters, the regenerated vegetation was characterized into two strata, and their diversity indexes were calculated (Shannon-Wiener, Margalef, and Pretzsch). The survival and ecological parameters of the established species were estimated for reforestation purposes. The most important species within the regeneration were characteristic of early successional stages, following anthropogenic activities. The highest abundance of families and individuals was concentrated in the Fabaceae and Poaceae families; the former, represented by the same species successfully established in reforestation, and the latter, by invasive herbaceous taxa. Within reforestation, Prosopis glandulosa, Diospyros texana, Cordia boissieri, Ebenopsis ebano, Vachellia rigidula, and Havardia pallens had survival rates of 76.92, 50.0, 40.0, 38.46, 24.24, and 20.0 %, respectively; the rest of the species had 0 %. The results obtained are relevant for decision-making in forest management at the TTS, as well as for the monitoring of this community in its various successional stages.
