Hi Kevin,

I am being told that the night time respiration excedes the day time inspiration.... The biologist feels that these plants, being invasive, are crowding out other indigenous plants and prohibiting biodiversity and therefore man should intervene to remove them and to replant a variety of plants....

I will attempt to make the argument that according to the Gaia theory, the earth is intelligently choosing the exact plants she needs in exact quantities to repair, restore, regenerate and reorganize itself and that furthermore the principle of succession is well established and that therefore a plant's inasiveness is only as long lived as its uselfulness in preparing the soil for the next generation...

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.

Hi All,

Can anyone tell me to to what extent reeds either add or remove oxygen
from a pond ? I am meeting with a municipal biologist next week who is
hell bent on removing ALL the reeds around a pond and her principal
arguments are that this must be done because the reeds are "invasive"
and deplete oxygen - I thought the roots pumped out oxygen allowing a
place for water purifying bacteria to live ?

Thanks in advance,

Claude
