Citizen science data reliable for studying large, non-endangered wild cats
image: Sequence of data collection and analysis with the study hypotheses. Initially, species' geographic coordinates were obtained, and each coordinate was categorized as either citizen scientist or researcher data based on the database. Subsequently, an environmental envelope was generated based on 19 bioclimatic variables. The envelopes were overlaid, and the percentage of the researcher's envelope overlapped with the citizen scientist's envelope was determined. A linear regression was performed, where it is expected that species with larger body sizes, closed habitat types, and nonthreatened statuses would exhibit greater similarity in the environmental envelopes determined by researchers and citizen scientists.

Anápolis, Brazil: A new study published in Biological Diversity reveals that citizen scientists generate environmental niche data highly consistent with professional researchers for large, non-endangered cat species. The analysis focused on 36 terrestrial felids worldwide and compared occurrence records from amateur contributors and qualified experts.
Body Size and Threat Status Drive Data Similarity
Researchers found that body size and conservation status strongly predicted niche overlap. Larger species and non-endangered felids showed significantly higher consistency between citizen and professional datasets. Habitat type (open vs. closed) showed no significant effect, challenging earlier assumptions about habitat-driven observation bias.
Niche Modelling Validates Citizen Science Utility
The team constructed environmental envelopes using 19 bioclimatic variables and calculated overlap percentages. Over 23 species displayed more than 50% niche overlap, with eight exceeding 90%. These results confirm that citizen science data can reliably support species distribution modelling and conservation assessments for accessible felids.
Implications for Targeted Biodiversity Monitoring
The study recommends structured citizen science projects prioritize smaller, range-restricted, and endangered cats, which remain under-sampled. Properly trained public participants can expand data collection while avoiding disturbance to vulnerable populations, strengthening global felid conservation strategies.
