Impacts of Bambusa bambos spread on seedling recruitment, mortality and regeneration potential of native species in tropical moist evergreen forests of Sri Lanka

Some native plants expand their populations rapidly in their home ranges, altering their structure and composition. Bambusa bambos, a native bamboo species, shows a rapid population expansion in tropical moist evergreen forests in the intermediate climatic zone, Sri Lanka. The present study was cond...
