Land use legacies affect early tropical forest succession in Mexico

Abstract Questions Agricultural expansion is one of the dominant drivers forest and biodiversity loss, shifting cultivation most widely used form agriculture in many tropical regions. Where forests have been cleared, they potential to recover once land abandoned. However, legacies use are often overlooked successional studies, a deeper understanding this legacy effect needed define efficient restoration practices using natural or assisted regeneration. Here, we analysed how land‐use history affects soil properties early succession on abandoned agricultural fields two contrasting Mexican socio‐ecological systems. Location Mexico, Oaxaca Chiapas. Methods We sampled monitored vegetation for 2 years after abandonment, interviewed landowners about their . Results Land‐use were clearly influenced by landowners’ social context (residence time, rural urban origin), topography type also constrained facilitated practices. Soil characteristics strongly affected three practices: mechanical tillage decreased N K; frequent herbicide pesticide increased pasture systems, stocking density bulk pH N. High‐intensity management practices, specifically machinery, had highest impact succession. When machinery was not used, frequency particularly weeding frequency, main factor influencing tree cover sapling diversity. Conclusions To facilitate post‐agricultural recovery, recommend efforts regeneration areas with low previous intensity frequency.

Tropical forest succession increases tree taxonomic and functional richness but decreases evenness

Abstract Aim Successional changes in functional diversity provide insights into community assembly by indicating how species are filtered local communities based on their traits. Here, we assess successional taxonomic and richness, evenness redundancy along gradients of climate, soil pH forest cover. Location Neotropics. Time period Last 0–100 years. Major taxa studied Trees. Methods We used 22 chronosequence studies 676 plots across the Neotropics to analyse Hill's trees, these vary with continental‐scale precipitation, surrounding Results Taxonomic richness increased, while decreased over time. Functional changed strongly when not accounting for but more weakly after statistically that largely driven richness. Nevertheless, increases correcting may indicate environmental heterogeneity limiting similarity increase during succession. The taxonomically‐independent decreases stronger filtering competition select dominant similar trait values, many rare traits added community. Such also lead increased redundancy. varied resource availability were harsh, resource‐poor environments, weak benign, productive environments. Hence, facilitation important, whereas weaker abiotic allows high initial changes. Main conclusion found succession, mainly caused increasing number due arrival new changing (a)biotic filters.

Land use history and landscape forest cover determine tropical forest recovery

Journal of Applied Ecology, Journal Year: 2024, Volume and Issue: 61(10), P. 2365 - 2381

Abstract To conserve biodiversity and combat climate change it is vital to restore forest ecosystems. Natural regrowth a nature‐based solution forests, but has rarely been evaluated how this affected by the combination of previous land use intensity surrounding cover, varies between two main tropical types; dry wet forests. Thirty‐three plots were established on abandoned agricultural fields in (13 plots) (20 Mexico monitored 3 years for following tree community attributes: structure, diversity, regeneration mode, potential symbioses with N fixing bacteria mycorrhizal fungi.

Maximizing Tree Diversity in Cocoa Agroforestry: Taking advantage of Planted, Spontaneous, and Remnant Trees

Cocoa production stands as the primary driver of biodiversity loss in West Africa. In response to this challenge, agroforestry emerges a promising solution restore forest cover and preserve agricultural landscapes. Despite distributions millions trees farmers through various sustainability initiatives, survival rates planted have been disappointing cocoa fields. However, many non-planted currently exist fields, including from spontaneous regeneration remnants previous forests. Our study aims explore origins tree current Ivorian fields identify key socio-environmental determinants. Across 150 more than 10,000 were botanically identified, allowing estimation diversity complementarity levels between planted, spontaneous, remnant cohorts, linked variables within Bayesian modelling framework. Results revealed that exhibited much greater trees, with latter showing important other cohorts. Moreover, each cohort was influenced by distinct set environmental factors such climate soil composition, highlighting need consider unique history location field support development. Effective maximisation thus relies on preserving vital sources propagules for natural regeneration, while carefully selecting complementary introducing trees. Furthermore, recognizing farmer's identity factor shaping observed underscores importance raising awareness among offering recognition training, particularly young
