Abstract
Small hydroelectric power plants are included
among the clean energy production sources,
and they are attractive as a business. Besides,
in force regulations give them environmental
licenses and make a soft control. Also, there
are tax and financial advantages and flexibility
for them. As a consequence, if many of those
plants accumulate in a watershed or are
established with not enough precautions, the
biological characteristics of the place can
be severely affected. Objective. The effect
was assessed and the transformation of the
vegetation with a diameter equal or above
10 centimeters at the height of human chest
was estimated, with the hydroelectric plants
installed in the town of Sonsón, following
Conesa´s model and another one proposed by
the authors. Methodology. The assessment
of the impacts was performed with both
models and the structure, composition and
the diversity of the vegetation around the
small hydroelectric power plants before the
facilities were installed, were determined.
Results. The highest impact found was the
removal of the topsoil to adequateworkshops,
entrances of tunnels, temporary accesses,
machinery rooms and other constructions,
and this soil cannot be recovered. The effects
are irreversible, accumulative and persistent
over time. Conclusion. With the model
developed from the revision and collection
of data from other small hydroelectric
power plants with similar conditions, both
environmental and in terms of the size of
their construction processes, a very precise
estimation of their impacts on the flora was
achieved.
