However, their forest definition does not reflect ecosystem function or biotic composition. These structural and climatic definitions inflate forest estimates across the tropics and undermine conservation goals, leading to inappropriate management policies and practices in tropical grassy ecosystems.enBiomeGeographyEcosystemForest ecologyTropicsAgroforestryTropical forestEcologyForest managementEnvironmental resource managementletter
