Análisis de la riqueza vegetal y el valor de conservación de tres áreas incorporadas a la Reserva Ecológica del Pedregal de San Ángel, Distrito Federal (México)

Abstract

Se evaluó la riqueza vegetal y el valor de conservación de tres zonas incorporadas recientemente a la Reserva Ecológica del Pedregal de San Ángel: dos añadidas a la zona núcleo suroriente (SO 1 y S02) y el área de amortiguamiento A13. Se registraron 199 especies (57.6% de las reportadas). Se registraron 148, 152 y 149 especies en SOi, S02 y A13, respectivamente. En Al3 se registró a Mammillaria haageana subsp. san-angelensis, una subespecie en peligro de extinción, a Bletia urbana, clasificada como amenazada, y a dos nuevos registros para la reserva: Eupatorium pazcuarense y Adiantum andicola. Se reconoce también a Pennisetum clandestinum, por lo que se eleva a 340 especies el número de especies registradas en esta reserva. Utilizando un índice de valor para la conservación basado en ocho parámetros, se encontró que el sitio Al3 tiene mayor valor (21 puntos), seguido por el S02 y SO 1, con 16.5 y 10.5 puntos, respectivamente.
