Resumen

Se han iniciado esfuerzos de restauración en gran parte del mundo, con la finalidad de revertir los impactos causados por la vegetación exótica que invade sitios perturbados. Este estudio buscó conocer la respuesta de anfibios y reptiles a la restauración de hábitat en el delta del río Colorado, al comparar la riqueza y la diversidad de la herpetofauna en 2 sitios restaurados y perturbados en Mexicali, Baja California. Se instalaron 8 sistemas de trampas de caída en 2 sitios, con 2 réplicas cada uno, de mayo del 2018 a marzo del 2019. Se obtuvieron 402 observaciones de 18 especies (3 anfibios, 15 reptiles), incluyendo 3 especies exóticas. Los sitios restaurados presentaron mayor riqueza y diversidad que los sitios perturbados, incluyendo 6 especies enlistadas en la NOM-059-SEMARNAT-2010. Los resultados sugieren que los reptiles responden positivamente a los hábitats en restauración del delta del río Colorado. Sin embargo, solo 1 especie nativa de anfibio fue registrada en baja abundancia. Se recomienda continuar con las acciones de restauración, aumentando la diversidad de plantas nativas, ampliando la disponibilidad de hábitats acuáticos e incluyendo acciones de control de especies exóticas acuáticas que permitan la recuperación de los anfibios nativos.
