Ecological and socioeconomic impacts of Lantana camara invasion: A case study in central India

Abstract

The study investigates the impact of Lantana camara, an invasive alien species, on biodiversity, agricultural productivity, and non-timber forest products (NTFP) in central India. The aggressive growth and spread of the weed have resulted in the displacement of native flora and fauna, leading to substantial ecological and economic consequences. Regression analysis reveals a statistically significant negative correlation between proximity to Lantana camara infested plots and average annual crop loss, with closer proximity resulting in higher crop destruction. Additionally, a Wilcoxon signed-rank test confirms substantial reductions in NTFP collection post-infestation, highlighting significant economic losses for local communities reliant on these resources. The study also employs linear and non-linear regression analyses to assess the impact of Lantana camara infestation on species richness across various vegetation species, revealing a consistent negative effect on biodiversity. ANOVA and SIMPER analyses further corroborate these findings, indicating significant decreases in species richness, particularly among NTFP species. The results underscore the urgent need for effective management strategies to mitigate the adverse ecological and socioeconomic effects of Lantana camara invasions, emphasizing conservation efforts and sustainable practices to support the livelihoods of affected communities.
