While some groups (such as avian species) are well known, others (such as invertebrates) are not. This gap in knowledge is partly due to the lack of interest shown in the study of certain species and partly to the difficulties inherent in identifying them. The vast, diverse nature of The Grande Cariçaie’s natural environment is the principle reason for its incredibly rich fauna. If these environments can be protected into the future, then it may be possible to preserve the current diversity of species as well.
Below is a section of the inventory, which includes the listed numbers of species per group and a percentage estimate of what the true number of species may be.
