Structure and phenology characterization of four tree species of tropical deciduous forests

Abstract

Objective: To determine the structural and phenological characteristics of four major tree species in the tropical deciduous forests. Design/Methodology/Approach: To determine their structure, ≥ 10 cm wide trees were registered at a height of 1.30 m in 30 sites of 500 m2. For phenological purposes, seven sites were selected. The following phenological stages were evaluated: dormancy, vegetative, flowering, fruiting, and seeding. Results: Four hundred and five individuals belonging to the four species under study were found: copal ancho (Bursera copallifera (Sessé & Moc.) ex DC. Bullock), Mexican kidneywood (Eysenhardtia polystachya (Ortega) Sarg.), tecolhuixtle (Mimosa benthamii (J.F. Macbr. var. bentha-mii)), and tepemezquite (Lysiloma divaricatum (Jacq.) Macbride). Tepemezquite ranked first according to the Relative Importance Value Index. Based on the phenological characteristics observed, three species lost foliage at some time of the year and only tecolhuixtle was evergreen. Study Limitations/Implications: The results and conclusions are limited only to individuals with ≥ 10 cm in diameter. Further results can be extrapolated from this data. Findings/Conclusions: The structural and phenological features of the four species evaluated in ejido El Limón have similar characteristics to those that have been described for this type of vegetation in other locations in Mexico.
