Integrated Biotic Community and Human Impact Model for Forest Ecosystem Management

This conceptual framework outlines a comprehensive model for understanding forest ecosystems by examining the interactions between biotic communities—flora and fauna—and their physical environment. It investigates factors such as geology, climate, soil composition, and human impacts like logging, land use changes, and management practices. The model integrates elements like forest structure, nutrient cycling, and ecosystem dynamics, providing insights for sustainable forest management, conservation efforts, and addressing challenges posed by climate change and invasive species.
