The riparian vegetation is presumably the jungle most strongly transformed by human labor. The particularities of the lands of the riparian environment are such that, in practically all the valleys in which accessibility is sufficient, the riparian forests have been eliminated, fragmented or profoundly modified and reduced to a narrow strip next to the channel. The vegetation is adapted to the peculiarities that the environment shows.
It is riparian vegetation, that is, it depends fundamentally on the humidity of the soil. For this reason, the riverside vegetation assumes as a primary conditioning factor the greater or lesser proximity and height in relation to the riverbed. This does not mean that it is completely autonomous from the climatic factors, precipitation and temperature, but it affects it to a lesser degree than other types of forest that need climatic zones.
Riparian forests are essential for ecological moderation, as they offer shelter for waters and soil, reducing rainfall and the forces of waters that reach rivers, lakes and dams, conserving water quality and restricting access to polluting agent to the aquatic environment. They also create commission agents that help conserve biodiversity; provide food and shelter for animals; building natural walls against the spread of agricultural pests and diseases; and, during their development, they soak up and establish carbon dioxide, one of the most important gases responsible for the climate changes that disturb the planet.
Among the threats to the subsistence of these forests can be replaced with agricultural and forestry crops, the redirection of the stretches on which they are based, the reconstruction of hydraulic infrastructures and desecration by invasive species. The riverside vegetation is connected with the variation of the fluvial environment, converting the variations of these methods into serious problems for the conservation of the surfaces and variety of the groves.
On the other hand, correct riverbank plant growth demands the work of a unified reasoning that agrees to characterize the different riparian communities with uniformity, so that the characterization of sections of rivers with high ecological value is approved, and that allows the correct choice of vegetal species for the salvation of rivers and degraded banks.
