Among the particularities that SISS-Geo (Wildlife Health Information System) presents, the audit and taxonomic validation work stands out. In biology, two major disciplines are essential for the identification of organisms: Taxonomy and Phylogenetic Systematics. While taxonomy defines and names living organisms based on their common characteristics, systematics classifies and organizes them according to their evolutionary (kinship) relationships. 

Taxonomic audit and validation are fundamental components of SISS-Geo's quality criteria. They ensure that information about registered organisms is accurate, reducing errors in data interpretation and increasing reliability in possible analyses. The identification of organisms is crucial because each species carries its evolutionary history, its geographic distribution, and its interactions with the environment and other species. In the context of health, this knowledge is essential for epidemiological surveillance, as it allows us to identify which species may be natural reservoirs of diseases, which act as vectors, and which are most susceptible to infectious agents. This information is vital for the early detection of zoonotic outbreaks and for the development of more effective strategies in controlling public health risks. 

Furthermore, precise taxonomic identification is fundamental for wildlife monitoring, as it allows for population tracking and provides data to aid in the preservation and conservation of species and in the planning of environmental management strategies. Thus, the platform can offer valuable information for scientific research and environmental public policies. 

However, it is important to highlight the limitations of the taxonomic validation process in citizen science projects, such as SISS-Geo. The quality of photographs, the proximity and angle of image capture of the animals, the specific morphological characteristics of the taxon, and precise descriptions in scientific literature are factors that can impact the accuracy of identification. Therefore, efforts are made to identify at the lowest possible taxonomic level (Order > Family > Genus > Species), with the support of volunteer researchers specialized in various zoological groups. 

In the system, each record can be checked for the status and progress of the audit process, being classified as: pending, checking with specialists, audited, inconsistent, irrelevant, or valid. The record verification process in SISS-Geo consists of two distinct stages: the audit, carried out by the Pibss team (Institutional Platform for Biodiversity and Wildlife Health), and the taxonomic validation, which may involve the support of registered specialists. During the audit, pending records undergo a screening process, in which truthful (consistent) records are separated from duplicate or training records (inconsistent). From this first screening, the record is already considered audited. In the second stage, consistent and relevant records for the platform are identified, differentiating them from records representing domestic animals or invertebrates (irrelevant). With the consistent and relevant records screened, taxonomic validation begins, in which Pibss professionals identify the animal represented in the record down to the species, genus, or family level, classifying it as valid. 

During the validation process, the auditor can count on the support of volunteer specialists registered in the system. When a specialist is consulted, the record's status is changed to “checking with specialist” until the identification is approved by the auditor.
