Finalized statment:
The data summarized above have been corrected as needed and prepared for future use. Actions to verify, correct or modify data were conducted by R script manipulations, physical examination of samples, review of excel spreadsheets and inspection of hard copy materials.
Recommended mitigations:
Ongoing work:
• Data wrangling
• Update/modify/clarify species list to ensure accuracy
• Protocol to methods drafting
