A biodiversity data analyst is validating species occurrence data across 320 survey plots. Initial data shows 70% plot records as reliable. After cross-referencing with GPS logs, 80% of the unreliable plots are found to have minor GPS drift. How many plots are still considered unreliable?

How A Biodiversity Data Analyst Is Validating Species Occurrence Data Across 320 Survey Plots Across the United States, growing attention is shifting toward environmental monitoring and biodiversity integrity. A biodiversity data analyst plays a crucial role in ensuring the accuracy of species occurrence records collected from field survey plots. In a recent large-scale effort involving 320 survey sites, initial validation revealed 70% of plot records as reliable—highlighting both progress and persistent challenges in field data collection. The next critical step? Understanding what remains uncertain. With minor GPS inaccuracies responsible for most inconsistencies, how many plots still require re-evaluation? This analysis matters because reliable data underpins conservation strategies, ecological research, and policy decisions. Cross-referencing digital field data with GPS logs helps identify patterns of uncertainty, especially when location errors—like minor GPS drift—compromise record accuracy. While the analyst confirms 70% reliability, 80% of the 30% unreliable plots stem from subtle geographic drifts, meaning those records remain flagged for closer review. ### The Analyst’s Critical Role in Field Data Validation
