“…In this context, studies of natural regeneration are extremely important because they generate results that enable a better understanding of the behavior of tree communities (Aguiar et al, 2017). With regard to this, a greater understanding of the plant succession process in areas with different disturbance histories is essential, as it can generate data that detect the need to facilitate natural regeneration actions, as well as forest management incentives that facilitate recovery of other similar areas (Larsen et al, 2019). Thus, these studies can support the conservation and recovery plans of forest ecosystems by enabling the identification of limiting environmental factors and inferring the future dynamics of forests (Aguiar et al, 2017;Dalla Rosa et al, 2016).…”

This study evaluated changes in the structure for remnant Mixed Ombrophilous Forest recovering from logging, which ceased over 40 years ago. Regarding the dynamics of the floristic composition of natural regeneration, 18 species remained (23.38% of the total) and 27 new species entered (35.06% of the total). The greatest increases were observed for Allophylus edulis, Myrsine umbellata, and Miconia cinerascens. When analyzing the dynamics of regeneration in ecological groups, it was observed that pioneer species had a similar value in both surveys (29.4% and 29.6%); secondary species decreased from 56.6% to 52.8%, and late-successional species increased from 0.2% to 6.0%. Therefore, the forest fragment studied is in a healing phase after disturbance, characterized by the increased regeneration of pioneer species as a result of sufficient light entering the interior of the forest.

“…Algunas especies arbóreas que caracterizan a estos fragmentos son Alchornea latifolia, Ampelocera hottlei, Apeiba tibourbou, Brosimum alicastrum, Bursera simaruba, Calophyllum brasiliense, Cecropia obtusifolia, Ceiba pentandra, Cojoba arbórea, Cymbopetalum baillonii y Erblichia odorata (Chazdon et al 2007, Ibarra-Manríquez y Cornejo-Tenorio 2010; CONAFOR y Colegio de Postgraduados 2014). Este proceso depende de la disponibilidad de germoplasma, resiliencia, factores climáticos y tamaño y duración de la perturbación (Chazdon et al 2007, Zermeño et al 2016, Larsen et al 2019.…”

Background. Agriculture and cattle raising are the main factors to forest loss and fragmentation, therefore, to reduce their negative impact, new production systems have been implemented. The Agroforestry and Silvopastoral Systems are corridors for fauna and source of natural regeneration, promoting the coexistence of several species and providing goods and services to the human being. Until now, the effects of the agriculture and cattle raising in the composition and configuration at the humid tropical forest in Sierra Norte de Puebla are still unknown. Objective. To compare the changes in the composition, stand structure, richness and tree diversity between an Agroforestry System (AFS), Silvopastoral System (SPS) and a Second-Growth Forest (SGF) in Palmagtitan, Sierra Norte de Puebla. Methodology. We established sampling units in three land management systems where we recorded specie, normal diameter total height, and cover of every tree in the area. For each attribute, we generated categories. The stand structural attributes such as density, basal area, cover and normal diameter were calculated and compared between land management systems with the multiple comparison DGC method. We obtained and compared the Margalef’s richness, Shannon’s diversity, Equitability and Fisher’s alfa indices and Hill’s numbers. The floristic similarity was analyzed with the Sorensen coefficient. Results. We identified 44 species from 24 families. The families Burseraceae, Moraceae, Rutaceae, Euphorbiaceae and Fabaceae were the best represented. Only the tree density presented statistical differences between the land management systems. The Margalef’s richness index was different only in the SPS. The Shannon’s diversity index and the Hill’s numbers showed a major diversity in the AFS than in the SGF and the SPS. The similarity in the floristic composition between AFS and SPS was 16.6%, between AFS and SGF 38.30% and between SPS and SGF 26.23%. Implications. The characterization of the stand structure and tree diversity permits a better decision-making about the production systems management and the forest patches conservation. The tree management and the presence of native species in production systems allow to integrate handling practices to provide food safety and biodiversity conservation. Conclusions. The composition, stand structure, richness, and tree diversity in the three land management systems were determinated by the management and land use history. As the expected, the SGF got the biggest density, but (contrary to the stipulation) the most diverse was the AFS. It is necessary to know the ecosystems configuration and composition to devise management strategies that allow us to integrate the production and ecosystems conservation.
