Aquatic Plants

PJC lakes have a thriving aquatic plant community with a wide variety of species including some invasive species and others that are beneficial. Each year as part of our efforts, we try to stay informed of the latest news of outbreaks by measuring and indentifying aquatic plants.Our mission is to preserve our natural state by monitoring changes and attempting to avoid invasive species by identification and removal.

Painter, Juno, and Christiana Lake Aquatic Plant Survey- Thurs September 6th, 2018

Painter, Juno, Christiana plant survey project is a joint effort between the PJC lake association and the Edwardsburg High School Biology Program. The goal of the project is to survey the three lakes for beneficial and harmful aquatic plants. With the information gained from the mapping, homeowners can make sound decisions about care and maintenance of the lake habitat and invasive weed control. High School honor students will gain experience in collecting and identifying plant materials and recording the results. The students will also use the results to interpret the data and share that information with lake owners. It is our hope that this project will inspire the students to become responsible lake stewards in the future and bring both groups together for a common goal... a better understanding of our lakes.

We've included some information below from the Michigan.gov/invasives, MSU, and the Michigan DNR.

Basic Background Info on Ecology - There are 3 main zones for rooted plants -

  • Shore Zone - These plants have root systems that grow from the wet soils of the shore out to a water depth of 2ft to 4ft. Examples of this type of plant are : Cattail, Bulrush, Arrow Arum, Arrowhead, and Pickerelweed
  • Shallow Littoral Zone - These plants are submerged plants with floating leaves and extends from about 2ft to 6-8ft. Examples include: water lilies, water shield, and many species of Pondweed
  • Deep Littoral Zone - Plants grow entirely submerged with a small tip breaking the water and roots deep from 6ft to 12ft in turbid lakes or up to 20ft in clear lakes. Common plants in this zone include: milfoil, coontail, sago pondweed, bushy pondweed, stonewart, waterweed, and wild celery.
