The traditional methodology employed to identify and evaluate the impacts on the environment using development projects, has followed an integrated, global, systematic and multi-disciplinary analysis of these impacts, identifying their causal connections. Objective. Create analternative model to assess the effects and estimate the transformations that plant communities of breast height diameter (larger or equal to ten centimeters) suffer throughout the installation of small hydroelectric plants. Methodology. Material was collected from twelve projects in Antioquia and Caldas. These projects are currently running or about to do so. From each project, the chosen variables were weighted. The values obtained were statistically analyzed. Results. A statistical model is proposed, including ecosystem variables, which helps assess flora impacts considering every asset and associated service. Conclusion. This method shows which factors (associated with vegetation) present greater impacts and their substantial effects due to the implementation of development projects.esCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráImpacto ambientalImpacto ambiental - EvaluacionesVegetaciónCentrales hidroeléctricasArticle
