New Polygon and UPI Treatment Tools

One of the most popular features of BioBase is the polygon tool that allows users the ability to trace out areas of their maps for detailed calculations of mapped attributes (e.g., area, depth, water volume, aquatic vegetation statistics).  Until now, users could not use the same polygon on multiple trips.  That has changed and now any polygon a user creates in any trip will be available in all trips to that waterbody!  Now, users can monitor change to aquatic habitat within specific areas of interest (Figure 1).  Further, users can upload and overlay waypoints within polygons, and thus inform the composition of the polygon area (e.g., aquatic plants, substrate composition, muck depths, reefs, etc.)
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
BioBase teams up with UPI to deliver precision herbicide treatments
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.

Citizen Lake Mapping: Power of Aggregation!

Ten Mile Lake in Hackensack, Minnesota is one of many crown jewel lakes of Minnesota.  It's no wonder the Ten Mile Lake Association is serious about lake monitoring and conservation.  When BioBase approached TMLA member and hobby Fisheries Biologist Dr. Bruce Carlson in late 2012 demonstrating how members could passively log their sonar data and map habitat while enjoying a pleasure cruise or fishing, Dr. Carlson jumped at the opportunity.

Two hundred and twenty four trips spanning two seasons (2013-2014) and 5,065 acres (2,049 ha) later, Dr. Carlson and colleagues have produced the most accurate and detailed map of Ten Mile Lake on the planet (Figure 1)!
Figure 1. Track lines from 224 Lowrance sonar logs uploaded to BioBase and merged (left) and resultant contour map (right) produced automatically for Ten Mile Lake, Hackensack, MN USA.  Ten Mile Lake is a 208-ft (63-m) deep lake with 16-ft (5-m) clarity.
When comparing the hand-made maps of 1947 from the long-dissolved MN Dept of Conservation one has to wonder if creating this map took a dedicated and highly trained survey crew all summer to create this map (Figures 2-4)?  Now a critical mass of anglers or pleasure boaters with no mapping experience can create a community-sourced contour map that rivals anything produced by the most trained hydrologists using the most expensive "survey-grade" echosounders.
Figure 2. Original map of Ten Mile Lake created in 1947 by the MN Department of Conservation (left) next to the aggregated map produced by TMLA volunteers in 2014 after uploading to BioBase.  Maps created in the mid 20th Century remain the only maps offered to anglers and recreationists by a large number State Natural Resource agencies. Often these old maps are digitized and artfully recontoured and shaded for resale.

Not just an improvement in aesthetics!
The efforts of TMLA and volunteers from other Lake Associations across the US (e.g., Lake Paradise, Honeoye, Prior Lake) are producing not only pretty maps but also updated digital maps for the public and highly detailed fish habitat and aquatic plant data for aquatic researchers and managers.

First, public trips uploaded and aggregated both from BioBase and Insight Genesis mapping services from anywhere across the globe go to Social Map where they are available for viewing and downloading for free to Lowrance, Simrad, and B&G chartplotters (Figures 5 and 6).

Figure 6. Example map of Anten (Sweden) as viewed from Insight Genesis social map.  Professionals (BioBase) and Anglers (Insight Genesis) can community-source their mapping efforts to "fill-in" unmapped areas and create up to date digital maps for the public.
Second, Fisheries across the globe are threatened by a range of impacts too long to go into detail here and Aquatic Invasive Species are a global pandemic.  Researchers and managers mourn the decline of native aquatic species and often target habitat degradation or loss as a primary driver.  But rarely does information on habitat match the detail of the information on species declines. Citizen Scientists are now helping Natural Resource Agencies fill in the habitat knowledge gaps.  Returning to our example on Ten Mile Lake, now with updated bathymetry provided by TMLA volunteers and data sharing with MN Department of Natural Resources (DNR), Fisheries researchers have precise knowledge about how much cold, well oxygenated water is available for cisco (an important cold-water forage fish for popular gamefish).  Similarly, thanks to the efforts of the Prior Lake Spring Lake Watershed District and citizen volunteers on Prior and Spring Lakes, the response of invasive aquatic plants to watershed and in-lake management actions can be monitored.

Harnessing the power of technology and citizen science to conserve aquatic resources
"Doing more with less" or "working smarter not harder" are common cliché truths that will continue to limit the reach of publicly funded natural resource management programs into the foreseeable future. Through advances in affordable off-the-shelf consumer technology, automation, and the collective enthusiasm of citizen volunteers, good information on aquatic habitat need'nt suffer from declining public natural resource budgets.  Rather, by enrolling the help of citizens and technology such as described here, aquatic biologists and managers can focus their energies on using the information to make wise aquatic resource management decisions.
