Understanding The Effect Of Ranching On Quercus Brandegeei Recruitment In The Sierra La Laguna Biosphere Reserve, Xavier O. Espinoza

DePaul Discoveries

In this study, we attempt to deepen our understanding of the mechanisms responsible for Quercus brandegeei’s observed lack of regeneration by identifying which animal species (wild and domesticated) most frequently were observed eating, passing by, or searching for seeds and seedlings. We established 10 paired plots (10 enclosed and 10 immediately outside enclosures) and positioned one motion-activated camera in each plot to observe animal visitations to Quercus brandegeei individuals over the course of several months (October 2019 – March 2020). No seeds and seedlings survived outside of enclosed areas at the end of the study based on their absence. Very …
