Achieving Taxonomic Accuracy & Consistency for Diatoms
• Increased need for data sharing
• Taxonomic harmonization
• Development of a proactive solution
• Collaborative planning that leverages existing projects, materials, and the internet to create a new approach to floristic treatments

The solution…

…is a collaborative effort. There is a need for taxonomic accuracy and consistency in US programs, and the effort is larger than individual investigators or labs can provide.

Priority of taxa
• 350 most common species identified from USGS and EPA surveys of flowing waters
• Species that are difficult to identify and commonly misidentified by analysts
• Species that are strong indicators for biotic condition

Outcomes from using the tool
• Taxonomic consistency
• Correct taxonomy
• Updating autecological information; may be one of the biggest contributions of the effort
• Democratizing information
• Geography-associated information allows for tailor-made floras for water-body to regional analyses
![Page 21: Developing an on-line taxonomic guide to the freshwater diatoms of the United States: scope, process and initial steps Steve Moulton Sarah Spaulding National.](https://reader035.fdocuments.in/reader035/viewer/2022062801/56649e2d5503460f94b1d8b8/html5/thumbnails/21.jpg)
A look to the future: leveraging resources
• Current floristic and monitoring work is contributing to this effort (NAWQA, EMAP, NSF projects)
• Feedback from this resource to NAWQA list of names
• Herbaria provide specimens and literature; they receive upgrades in the identification of types and refined/upgraded taxonomy of their collections
• A sense of collaboration and transparency about the process prevails amongst the taxonomic experts
![Page 22: Developing an on-line taxonomic guide to the freshwater diatoms of the United States: scope, process and initial steps Steve Moulton Sarah Spaulding National.](https://reader035.fdocuments.in/reader035/viewer/2022062801/56649e2d5503460f94b1d8b8/html5/thumbnails/22.jpg)
A look to the future: further development
• Scaling up the number of taxa (from 200 to 5,000+)
• Broader community participation - managing work flows will be important
• Including additional records of geographic distribution and ecological range
• Specify data quality standards / increase confidence in datasets
• State agencies and others can write use of the diatom tool into task requirements
