Prioritizing threats to rare and endemic species: Expertise to insights

The protection of rare and endemic species is essential in the face of increasing dangers posed by climate change, urban development, invasive species, and various human activities. This study aims to assess and rank the major threats facing rare and endemic plant species in Pakistan using a comprehensive methodology. We combined field observations, literature analyses, and surveys of expert opinions to identify, prioritize, and evaluate the threats confronting these species. A Likert-scale questionnaire of 88 conservation experts was utilized to group and rank key threats. The findings reveal that climate change (85%) is perceived as the most significant threat, followed by urbanization (78%), invasive species (72%), and land use changes (70%). Additionally, pollution (65%) and unsustainable anthropogenic activities (60%) further exacerbate biodiversity loss. Correlation analysis indicates strong associations between urban expansion, agricultural intensity, and environmental degradation (r > 0.75, p < 0.01). ANOVA results show no significant differences in expert opinions across different specializations (p > 0.05). The study sheds light on the inadequacy of existing literature as it often leaves out underrepresented areas and species, leading to biases in priorities for conservation. This paper presents an overall framework for prioritizing conservation efforts, especially in areas where empirical evidence is barely available. It fills significant knowledge gaps through the input of specialists and helps policymakers reduce biodiversity loss and improve sustainable environmental practice. The research finally concludes that urgent and targeted approaches are necessary to combat the various threats facing endemic plant species. For biodiversity conservation, interactions of human activities, climate pressures, and invasive species need to be addressed to enhance ecosystem resilience and ecological balance.
