Just got my hands on this fantastic new book on #Charophytes of Europe and excited to see the most westerly dot on the distribution map of #Tolypella nidifica was from a snorkel survey i carried out on the Outer Hebrides of Scotland - over 20 years ago 😬 #MacrophyteMonday

One of the people fired from NOAA today is the director of the Ocean Acidification Program. That program also leads the U.S. government's effort on marine carbon dioxide removal (mCDR). The destruction of American science is incomprehensible.

Registration for the award-winning Michigan State University Extension Introduction to Lakes Online course is open! This introductory six-week online class is designed for anyone interested in gaining a greater appreciation for inland lakes including concerned residents, decision makers, local leaders, and lakefront property owners. Course instructors include faculty from MSU Extension and state agency personnel.

 

The course covers a variety of topics including lake ecology, watershed management, shoreline protection, aquatic plants, Michigan water law, and community engagement. These topics are explored online through video lectures, interactive activities, and discussion forums. Additional resources are also provided for those looking to dive deeper. Participants communicate with each other and instructors through lively discussion forums and biweekly Ask-an-Expert webinars which include guests from organizations such as the Michigan Department of Natural Resources and the Michigan Department of Environment, Great Lakes, and Energy.

 

Registration is open now through January 28, 2025. The cost of the course is $115 per person. Register by January 6 for an early bird price of $95 per person. Scholarships are available. Current individual members of the Michigan Lakes and Streams Association are eligible to receive a $95 reimbursement upon successful completion of the course.

 

A certificate of completion is awarded to those who complete the class. Participants also can receive continuing education credits including 16 Michigan Department of Agriculture and Rural Development Pesticide Applicator Re-Certification credits (8 commercial core and 8 aquatic) and educational hours in the MSU Extension Master Gardener, Master Citizen Planner, and Michigan Naturalist programs. Learn more and register at www.canr.msu.edu/lakesonline.
