| Summary: | Riparian forests occur as exuberant plant communities when compared with their surrounding environments alongside rivers, creeks and irrigation channels. These forests often act as corridors for local fauna communicating isolated vegetation communities. Information obtained through remote sensing was interpreted and used to create an inventory of flora and forestry as well as to compare two riparian communities. With this information the tree communities of both rivers were analyzed. A decrease in native vegetation coverage was detected and as a consequence an increase of agricultural lands. In 19 years the annual increment of agricultural land was 1.14% and 1.64% in each one of two rivers affecting about 0.4% of riparian forest. From the 25 tree species found in both rivers, 4 showed the highest importance value for each community. Species diversity (Shannon diversity index) was higher for Rio Cabezones than for Rio Ramos. Soerensen's similarity index was high when comparing both rivers. The highest tree species showed a balanced tree crown shape and a low crown/stem proportion. |
