A biodiversity data analyst is verifying species records from 450 field surveys. She confirmed 60% of the surveys during the first phase. In the second phase, she reviewed 120 more surveys and corrected errors in 85% of them. How many surveys remain unverified after both phases?

**A biodiversity data analyst is verifying species records from 450 field surveys. She confirmed 60% of the surveys during the first phase. In the second phase, she reviewed 120 more surveys and corrected errors in 85% of them. How many surveys remain unverified after both phases?** In an era of climate tracking and ecological accountability, the meticulous work of biodiversity data analysts shapes how scientists understand species distribution across the United States. As environmental data becomes increasingly vital for conservation policy and research, behind the numbers lies a complex process of verification and validation—work that ensures every species record is accurate and reliable. This article explores the current status of a key dataset where one analyst is validating thousands of field-collected survey results. --- ### How the Verification Process Unfolded
