|Figure 1. Comparison of changes to aquatic vegetation in 2013 and 2014 within the same delineated polygon area of a lake in Minnesota. Waypoints showing the presence of the native aquatic plant, coontail was also uploaded and overlain simultaneously to demonstrate how species information can be combined with the vegetation biovolume map to better understand aquatic plant bed composition|
Since its launch in 2011, BioBase has taken the guesswork out of aquatic plant bed mapping and delineation. Now with a partnership with United Phosphorus Inc, we've developed a treatment recommendation tool that automates the estimation of UPI herbicide based on the user-delineated polygon area, target species, desired product and application rate (Figure 2). Whole Lake treatment recommendations can be created if >20% of the lake area is mapped. Users control the accuracy and precision of treatment recommendations by their mapping coverage. A whole-lake prescription will be more accurate and precise if 100% of a lake is mapped with 40-m transects than 20% of a lake with 100-m transects. Optimal mapping coverage in different aquatic plant environment is an area of research that we are hopeful will grow!
|Figure 2. After a polygon is created, authorized users can click on the UPI Treatment Tool button and generate an herbicide recommendation based on one or more polygon areas or the entire lake.|
|Figure 3. After a treatment is saved, a treatment history is created. Click on the "view report" for report for the last sample treatment (see example).|
Embed Treatment Reports in Final Reports or Forward to Permitting Officials
Applicators and lake managers can also quickly produce automated vegetation summary and treatment reports (Figure 4). These static html reports are stored a remote file server and can easily be shared with lakeshore owner customers, partners, or government regulators. No account information outside of the trip owner is disclosed or accessible by recipients. These reports demonstrate the objective and transparent nature of BioBase and UPI tools, thus minimizing uncertainties (and controversy??) by all interests involved in projects.

By using objective, quantitative tools delivered by BioBase and the UPI Treatment Tool, the precise amount of herbicide can be delivered to infestations and thus control costs, maximize effectiveness, limit non-target impacts, and ensure regulatory compliance. If you are interested in using the UPI Treatment Tool (both current and interested future BioBase subscribers), please contact your regional UPI Sales Rep.
