"Plant" Profile - Lyngbya

We are definitely working our way into the heat of summer here at AERF.  Those in the business of aquatic plant management as well as those who just enjoy the water, often deal with the usual invasive culprits like Hydrilla, Eurasian Water Milfoil, and Water hyacinth during the time of year. Another invader, however, might not be as well-known, especially by those of us who recreate this time of year.  Our plant profile this week isn't really even a plant at all, but rather a cyanobacteria (blue-green algae).  This blue-green usually rears it's ugly head in the heat of summer and can have even more severe impacts than its well known invasive plant counterparts.

Plant Profile - Phragmites

Invasive plant species can become a "giant" problem for resource managers.  One true "giant", as far as invasive wetland and aquatic plants go, can be found on EVERY continent except Antarctica and is found highly invasive throughout North America.  This particular plant has two native varieties which occur in various parts of the United States, however a very similar invader variety from Europe can be found throughout much of the same territory and cause a variety of problems.  Its scientific name alone means "southern plant with fence-like growth"....
