The Southwest Region (SWR) is one of Nigeria’s six geo-political zones and comprises distinct states. It holds considerable significance due to its unique geographical features, economic vibrancy, pastoral heritage, fragile natural ecosystems. These ecosystems are becoming increasingly susceptible human activities the adverse impacts climate change. This study analyzed temporal spatial variations Normalized Difference Vegetation Index (NDVI) in relation key influencing factors SWR from 2001 2020. analytical methods included Sen’s slope estimator, Mann–Kendall trend test, Geographical Detector Model (GDM). analysis revealed significant variability vegetation cover, with dense concentrated eastern part region low coverage overall, reflected by an average NDVI value 0.45, indicating persistent stress. Human activities, particularly land use cover (LULC) changes, were identified as major drivers loss some states such Ekiti, Lagos, Ogun, Ondo. Conversely, Osun Oyo exhibited signs recovery, suggesting potential for restoration. found that topographic factors, including elevation, well climatic variables like precipitation, influenced patterns. However, impact these was secondary LULC dynamics. interaction detection further highlighted cumulative effect combined anthropogenic environmental on distribution, between topography being significant. findings provide essential insights into biological condition contribute advancing understanding patterns critical implications sustainable management conservation tropical forest

ABSTRACT Soil nutrient stoichiometry is fundamental to ecosystem functioning. However, it remains unclear how long‐term vegetation restoration affects its dynamics. This study utilized monitoring compare soil carbon (C), nitrogen (N), and phosphorus (P) stoichiometric characteristics with cropland as a control, across four stand types: (CK), natural secondary forest (NSF), Robinia pseudoacacia Pinus tabuliformis mixed (RPF), R. plantation (RF), P. (PTF). Specific focus was given organic (SOC), total (TN), (TP), well their C:N, C:P, N:P ratios. During 30 years of restoration, SOC TN increased by 11.65% 7.46%, while TP decreased significantly 11.74%. Furthermore, (NSF) stabilized the 25th year. Under artificial (PF, RF, RPF), initially but recovered initial values after approximately 13–15 years, Finally, C:N ratio did not change significantly, C:P ratios varied temporally early fluctuations (0–10 year period), significant increases in mid‐term (10–20 stabilization late stage (20–30 period). Climate indirectly influenced SOC, TN, through factors. were directly affected both factors, primarily Over 30‐year period, biomass gradually accumulated, dynamics shifted from being soil‐mediated vegetation‐mediated. Long‐term enhances biological pathways, trees herbaceous plants playing key roles optimization. NSF more effective than enhancing accumulation optimizing These results offer valuable guidance for developing strategies Loess Plateau.

Understory vegetation is one of the most important links for improving forest biodiversity, and its restoration conducive to sustainable development, energy flow, nutrient cycling. However, little known about developmental dynamics main driving factors long-time series coverage, biomass, diversity, species composition plantation understory vegetation. In a case study three typical plantations, with natural secondary as reference in Loess Plateau China, we collected from Robinia pseudoacacia Linn. deciduous broad-leaved plantation, Pinus tabulaeformis Carr. evergreen coniferous mixed an age span 10 50 years. (1) The coverage biomass results stands different ages showed R. be significantly higher than P. diversity changed stand age. growth resource imbalance, drastic changes stands’ environment caused by excessive intraspecific competition early stage restoration, are reasons that make undergrowth lower other types. (2) plantations revealed their degree community stability. Compared had stability, closely resembled forest. stability was lowest because it types converged, which due atypical contribution. (3) dynamic canopy soil nutrients were affecting composition. Stand density elevation limited communities restoration. Soil bulk key factor this effect weakens future studies, focus should on converged action further development trend species, choosing appropriate recovery strategy (active or passive), providing more possibilities intensive management under plantations.
