Regeneration of Abies religiosa in canopy gaps versus understory, Cofre de Perote National Park, México Agrociencia
Lara-González,Rogelio; Sánchez-Velásquez,Lázaro R.; Corral-Aguirre,Juan.
Some studies have shown that fir (Abies spp.) regeneration can occur either in canopy gaps or in understory. The purpose of this study was to know how canopy gaps contribute to fir regeneration. Points were randomly chosen in three fir forests, and starting from there the nearest gap was recorded. Likewise, other random samples were placed in understory with the same diameter as that of the gap registered before. Gap age, gap size, and tree seedling for each sample were recorded. The average gap age was 7.61 ±1.86 yr. The average gap size was 66±42.8 m². The most common gaps were of intermediate size (44-88 m²). Only seedlings of A. religiosa (H.B.K.) Schlecht. & Cham and Pinus montezumae Lamb, were observed either in gaps or in understory. The...
