Data Reviewer will flag all entries with more than one patch. It will also tell Hogle if the patch data collected in the field is not where it should be, which could also be a sign of bad data. Without such a check, incorrect DNA data can enter the database and lead to treatment of desirable plants and missed treatment of the invasive plants. Moreover, it can also lead to misidentification in future years based on the incorrect data and could lead to inaccurate categorization of the hybrid's site-specific characteristics.
