St. Joseph River Inventory 2020-2021 - Observations Map
This map (click the title above to link to the map) was created to help share some of the many observations of invasive species and other environmental conditions and features found while kayaking along the main channel of the St. Joseph River as part of a project conducted by the St. Joseph County (Michigan) Conservation District and the Southern Michigan Invasive Species Team beginning in August 2020. The project team kayaked, captured video, and took water quality measurements over the length of the St. Joseph River, a distance of 206 miles from the headwaters in Hillsdale, Michigan to the river mouth at St. Joseph/Benton Harbor, Michigan. The goal of the project, funded by the Great Lakes Restoration Initiative, was to conduct an inventory of invasive plant and animal species and related environmental factors to help three regional Cooperative Invasive Species Management Areas (CISMAs) in their efforts to protect native habitats, native biodiversity, and water quality in the St. Joseph River watershed. Additional funding was received from the Friends of the St. Joseph River, and in-kind support was provided by WaterWays|SEM, L3C.
The types of observations made and mapped include aquatic and terrestrial invasive species, birds and other wildlife, excessive algae growth, wooded floodplains and wetlands, eroding river banks, important fish and wildlife habitat features, old bridges and other structures, accumulated trash and other debris, stormwater and wastewater discharges, and water quality including water clarity, dissolved oxygen, water temperature and specific conductance. The map also includes links to several short video segments obtained during the inventory. Several videos provide interactive 360 degree river views. These links offer a first-hand virtual look at the river as it was observed during the project.

The project team hopes that sharing this information will help inform and inspire continued efforts throughout the watershed to learn about, protect, and restore this remarkable river.
