| description | The watershed of the Pilón River is important for its water capture for commercial agriculture and for the conservation of the biological diversity of Nuevo Leon state. However, the magnitude of the forest and shrub fragmentation has not been determined, and the remaining fragments of higher conservation priority have not been identified. This study evaluates the vegetation fragmentation, using the fragment size and the relation between the perimeter and the fragment area (P/A) as indicators of size and shape, as well as the distance to the nearest neighbor and the intersection index and juxtaposition as connectivity indicators. These indicators were calculated in maps generated through satellite images Landsat of 1974 and 2000 interpretation (classification supervised and stratified). The results show statistically significant changes in the size and shape of fragments as well as in connectivity for all plant communities evaluated. The communities more affected by fragmentation in their size and shape were Abies and Oak forests, as well as the huizachal (Acacia scrub), piedmont scrub and pine forest. In its connectivity, fragmentation was more severe for Tamaulipan thorn scrub, piedmont scrub and desert scrub as well as huizachales. The fragments with higher priority conservation were determined considering their functions as buffer zones and as vegetation for slope stabilization, through the criteria application in a geographical information system. The conservation of 347 fragments for buffer zone and 210 fragments for slopes stabilization is recommended. |

La subcuenca del río Pilón es importante por la captación de agua para la agricultura comercial y por la conservación de la riqueza biológica del estado de Nuevo León. Sin embargo, se desconoce la magnitud de la fragmentación de sus bosques y matorrales, y no se han identificado los fragmentos remanentes prioritarios para conservar. Por lo tanto, este estudio evalúa la fragmentación de sus comunidades vegetales usando el tamaño del fragmento y la relación entre el perímetro y el área del fragmento (P/A) como indicadores de tamaño y forma, así como la distancia al vecino más próximo y el índice de intersección y yuxtaposición como indicadores de conectividad. Estos se calcularon en mapas generados mediante interpretación de imágenes de satélite Landsat de 1974 y 2000 (clasificación supervisada y estratificada). Los resultados muestran cambios estadísticamente significativos en el tamaño y forma de los fragmentos de todas las comunidades evaluadas, así como en su conectividad. Las comunidades más afectadas por la fragmentación en su forma y tamaño son el bosque de oyamel y de encino, así como el huizachal, el matorral submontano y el bosque de pino. En su conectividad, la fragmentación afecta sobre todo a los matorrales tipo tamaulipeco, submontano y desértico, así como los huizachales. En este estudio se evalúan los fragmentos prioritarios a conservar, considerando sus funciones como zonas de amortiguamiento y de estabilización de laderas, mediante la aplicación de criterios en un sistema de información geográfica. Al respecto se recomienda conservar 347 fragmentos para amortiguamiento y 210 fragmentos para estabilización de laderas.
