Invasive plants in our lakes!

As a result of nutrient runoff and the introduction of foreign species, some fast-growing plants threaten the lakes and rivers of southern Quebec by modifying habitats, nutrient balance and oxygen levels of aquatic ecosystems. The monitoring of development of invasive species in our lakes is long and costly, delaying the early response needed to prevent further degradation.

The current project proposes a combination of aerial and aquatic drones adapted for the monitoring of the spatial distribution of underwater herbaceous species. This development will increase our ability to map and monitor the progression of invasive species and curtail the invasion.

A software will be developed to facilitate the planning and execution of field missions. This software will include the planning of the path followed by the drones and tools to combine the data layers gathered by the two types of drones together.

This innovative approach will improve the management of our lakes, and lead to the publication of articles in biology and hydrology.

Aerial and Aquatic drones

Field surveys will be realized using aerial drone cameras and use an algorithm to locate and map the spread of herbaceous plants.

The team will participate in the building, testing and deployment of an autonomous aquatic drone equipped with submersible underwater cameras to identify the species and percentage of surface coverage by each species.

Algorithms will be developed using neural networks for image analysis to identify herbaceous species and produce occupation area maps at 1m resolution.
