Livestock production in the tropics contributes significantly to global greenhouse gas emissions, so better understanding the role of silvopastoral systems (SPS) in mitigating such emissions is necessary. The aim of this study was to evaluate the amounts of carbon stored in the biomass and soil organic carbon (SOC) components of a Leucaena leucocephala cum Panicum maximum silvopasture system (SPS) compared to a deciduous tropical forest (DTF), and a grass monoculture (GM) in Michoacán, Mexico. The above- and below-ground biomass were measured by destructive sampling in the SPS and GM, while previously reported allometric equations were used to quantify biomass stocks in the DTF. The SOC concentration up to 30 cm was determined by dry combustion method. The SPS and DTF contained more aboveground biomass (41.8 ± 3.30 and 36.7 ± 5.72 Mg DM ha−¹) compared to GM (8.0 ± 0.76 Mg DM ha−¹). However, the SPS exhibited greater belowground biomass (16.4 ± 1.95 Mg DM ha−¹) than the other systems. The DTF had the highest SOC fraction in all depth classes with values ranging from 3.1 ± 0.07% to 3.7 ± 0.06%, respectively, compared to the other systems. The total carbon stocks in SPS was similar to DTF (120.7 ± 10.97 vs. 120.9 ± 6.38 Mg C ha−¹) but was significantly higher than GM (78.2 ± 8.41 Mg C ha−¹). In dry tropical conditions, SPS displays enormous potential for increasing biomass and soil carbon stocks compared to the GM and can thus be used as a greenhouse gas mitigation strategy in livestock production systems.

Resumen en español

Los estudios detallados para comprender como los bosques neotropicales se reestablecen en el tiempo, a través de la sucesión secundaria aún resultan necesarios. Entre los mecanismos de regeneración que actúan en los bosques tropicales, el rebrote de árboles predomina en especies leñosas, con la ventaja de reiniciar el crecimiento de raíces establecidas, que permiten restituir el dosel forestal. El objetivo de este estudio fue identificar y cuantificar las especies arbóreas con capacidad de rebrote en distintas etapas de la sucesión secundaria (barbecho) después del sistema agrícola tradicional de milpa, comparadas con las comunidades del bosque tropical predominante en la Reserva de la Biósfera de Calakmul, y cómo influyen estas especies en la recuperación de la composición de este ecosistema. Se calculó el porcentaje de especies con y sin rebrote para cada etapa sucesional. Se registraron 13 972 individuos (32 % con rebrote y 68 % sin rebrote) y 168 especies (79 % con rebrote y 21 % sin rebrote), el porcentaje de individuos con rebrote va disminuyendo conforme avanza la edad de la sucesión. El número de individuos con rebrote y la composición de especies fueron significativamente diferentes entre etapas. Se puede concluir que la mayoría de especies arbóreas del bosque en Calakmul, presentan la capacidad de rebrotar, lo cual tiene influencia en el rápido proceso sucesional del bosque después de la roza-tumba y quema, restituyendo la cobertura y estructura forestal, así como la composición de las especies originales.

Resumen en inglés

Detailed studies to understand recovering of Neotropical forests over time, through secondary succession, are still necessaries. Between acting mechanisms of regeneration in the tropical forests, the arboreal resprout predominates in woody species, with the advantage of restart the growth from still rooting plants, allowing the restoring of forest canopy. The study aim was to identify and quantify the tree species with resprouting capacity in different stages of secondary succession (tree-fallow) after the traditional milpa agricultural system, compared with tropical forest communities in the Calakmul Biosphere Reserve and, enlightening how these species influences the recovery of the composition of this ecosystem. Was calculated the proportions of species with or without resprouting by successional stage. There were 13972 individuals (32 % resprouting and 68 % not resprouting) and 168 species (79 % resprouting and 21 % not resprouting), the percentage of individuals regrowing decreases as the successional stage progresses. The number of individuals resprouting and species composition were significantly different between successional stages. In conclusion, mostly arboreal species in the region of Calakmul, can regrow, which influences the successional development of the forest after slash-and-burn, helping to restore the coverage, structure, as well as species composition original.

Resumen en inglés

Effects of long-term rainfall inter-annual variation on regeneration dynamics of tropical dry forests (TDF) are still poorly understood. Such understanding is particularly important to assess the regeneration potential of TDF in landscapes subjected to slash-and-burn farming management. Here, we studied from 2004 to 2016 the effects of inter-annual rainfall variation on the dynamics of regenerative communities of woody species during the old-field succession of a TDF in Western Mexico. Over the study period a severe drought, caused by an El Niño Southern Oscillation (ENSO) event in 2005, and two hurricanes (Jova, 2011, magnitude 2; Patricia, 2015, magnitude 4) were experienced. In 2004, we established a chronosequence of abandoned cattle pastures and old-growth forest sites, which were assigned to four successional categories, each one with three sites: Pasture (0–3 years fallow age), Early (3–5 years), Intermediate (8–12 years), and Old-Growth Forest (without any human disturbance). At each site, seedlings, saplings and resprouts 10–100 cm height of shrub and tree species were tagged, taxonomically identified, measured in height and monitored over 12 continuous year intervals. At each year, all new plants reaching 10 cm height were recorded and considered as recruits. Community rates (recruitment, relative growth rate in height, mortality, species gain and species loss) were calculated per year, considering all plants combined and separating shrub from tree species. All community rates varied notoriously in response to temporal rainfall variability, with almost null interaction with successional category. As expected, mortality and species loss rates declined as the amount of rainfall increased, especially when precipitation of the current and the previous year were taken into account; these rates peaked in the ENSO year and were still high in the following year.

Unexpectedly, recruitment and species gain rates also declined with the increase in rainfall, especially with the amount of rainfall in the current year. Overall, community rates of tree species were more responsive than those of shrub species to temporal rainfall variation. The ENSO-related drought event produced a short and transient instability in the plant density and species density of regenerative communities. However, ENSO effects were smoothed out by subsequent rainy years, leading to a net increase in plant density and species density in all successional categories, especially in the younger one. Overall, our study shows that global (e.g. ENSO) and regional (e.g. storms, hurricanes) climate factors play a key role on forest succession, modulating the speed of the TDF regeneration dynamics. We conclude that low impact agricultural land use and the presence of good levels of remnant forest cover in the landscape confers a high potential for regeneration in abandoned agricultural fields, even under the impact of severe droughts and severe hurricanes.
