“…However, reviews published in the years after 2000 began to discuss a possible change in the rate of deforestation and beginning of reforestation in parts of Mesoamerica (Bray, 2009). Evidence supporting this prediction may be shown by Vaca et al (2012) Large differences in species composition can exist between vegetation types which are difficult to distinguish remotely, such as regenerating deciduous forests and native scrub ecosystems (Gordillo-Ruiz et al, 2020). Species composition, diversity and succession stage can influence differences in vegetation responses to climate trends and ET (Ballinas et al, 2015;Sakschewski et al, 2016).…”

Changes in atmospheric CO2, ocean temperature, and regional vegetation conditions in Mesoamerica indicate that significant trends in temperature and rainfall may have occurred in the Sierra Madre de Chiapas, Mexico. This is an important region for flora and fauna which could be affected by climate trends. We aimed to determine if and where (27-year) climate trends had occurred in the Sierra Madre and lower elevation regions between 1990-2016, if these trends were part of longer term 1960-2016 (57-year) changes, and how changes in large-scale and regional/local conditions may be influencing these trends. In the Sierra Madre, overall minimum daily temperatures increased, maximum temperatures decreased, and most significant mean temperature trends were cooler during the 27-year period. Both the start and end of the wet season trended earlier in the year, and wet season rainfall increased significantly. Trends were not significant during the 57-year period in the Sierra Madre; however, in the adjacent Pacific coast region, significant warmer temperature trends continued during this period. Within regions, there was large variation in temperature and rainfall changes and some local trends were opposite to the regional averages. Large-scale processes of warming sea surface temperatures in the east coast of Mexico, a change from the positive to negative phase of the Pacific Decadal Oscillation, and increases in atmospheric CO2 may be influencing these trends. At the regional scale, increases in dense vegetation and evapotranspiration since 1990 may have created characteristics favoring a positive feedback of higher ocean-based moisture and vegetation-based precipitation cycling.

“…An important characteristic of the species that contribute to the regeneration of the disturbed TDF is their high capacity for colonizing sites that are in very poor condition, which makes them inherently resilient. Moreover, even though the rapid recovery of the tree population has occasionally been noted after a disturbance, the recovery of floristic structure and composition is slow [19].…”

Effect of Pre-Germinative Treatments on Eight Priority Native Species for Reforestation in the Tropical Deciduous Forest

et al. 2023

Increasing the germination percentages from chemical and/or mechanical processes in native species is vital for the conservation of the species. The objective was to evaluate the effect of different treatments on the germination process of species belonging to the tropical deciduous forest (TDF) in a forest nursery. Eight species of trees and shrubs reported to be native to the TDF were selected; the seeds were collected from various sites of the state of Queretaro, Mexico. A randomized design of four replicates with 25 seeds was used, for which three pre-germinative scarification treatments were evaluated for each species: (1) thermal scarification (TS), (2) mechanical scarification (MS), and (3) chemical scarification (CS). Germination was considered as the protrusion of cotyledons onto the substrate and was recorded every 48 h for 60 days. A significant difference was observed between treatments (p ≤ 0.05). The mechanical treatment (MS) obtained the highest germination percentage and the least variation, in contrast to the thermal, chemical, and control treatments, which presented the lowest amount of germinated seeds. The MS treatment was the most effective for all the species studied because it allowed for 100% of the germination to be achieved.
