Aquatic Vegetation Mapping

Where plants grow in your lake or reservoir, how dense the beds are and which species are there.

Why plant surveys matter

Vegetation surveys for targeted management

Aquatic plants support oxygen production, habitat and water quality, but uncontrolled growth, especially from invasive species, leads to oxygen depletion, poor water quality and lost recreation.

Our surveys assess vegetation coverage, species composition and biomass density so we can build management plans that keep beneficial plants and control nuisance or invasive species.

How we survey

Sonar, GPS and field sampling

Using sonar imaging, GPS mapping and field sampling, we document plant diversity, distribution and seasonal growth, and pinpoint dense growth and invasive species that need treatment.

Invasive plants such as Eurasian watermilfoil and curlyleaf pondweed spread quickly. Knowing where they are and when they grow lets us treat at the most effective time, preserve native plants, keep open water clear and avoid expensive emergency treatments.

What you get

Plant community survey results

Maps and numbers you can compare from spring to late summer, or before and after treatment.

Plant biovolume map

How much of the water column plants fill, from bare bottom to growth at the surface.

Coverage statistics

The share of the bottom with plants and the deepest depth they grow.

Species locations

Each sample point identified, with invasive plants such as Eurasian watermilfoil flagged.

Season and treatment comparison

Repeat surveys on the same base map show what spread, what declined and what a treatment did.
