Claude,

Wetland plant roots provide conduits for air, which includes oxygen, to
enter the soil. During the day the plants produce oxygen and at night they
use it in respiration. A pond without plants is not healthy. "Invasives" are
merely aggressive successional species that colonize disturbed areas. The
only time plants rob oxygen is when they die and rot in an aerobic fashion.
The cycling between aerobic and anaerobic states is the point of a wetland.
What is the issue for the municipal biologist. Does she want to plant other
plants there? It is not about species, but function.

Kevin & Dr. Bitchface (Mindy)
