D, Co.parison with Salt Marsh Habitats

Certain characte~istics of the ~egion are similar to those
within salt marsh habitats. These include water quality and
wind velocity. Other cha~acteristics are distinctly diffe~ent,
These include insolation, temperature, humidity, and
p~ecipitation,

1. Water Quality

Table IV gives the composition of major elements within
seawater, The propo~tionate composition of most ions is nearly
identical to Glenwood Springs water. Magnesium is approximately
seven to eight times as abundant in seawate~, and bicarbonate is
about fivefold higher in proportionate concentrations within
Glenwood Springs water, Glenwood Springs has a TDS of 53% of
this seawater formulation.

The significance of this is that coastal salt marsh plants
should have little difficulty adjusting to the ionic composition
of Glenwood Springs water,

2, Wind Velocity

As will be discussed in the next section, wind velocity is an
important determinant of both rates of transpiration and
growth, A fairly low speed is required to provide sufficient
air flow to break down the boundrary layer at the ai~-leaf
surface interface to promote good gas exchange, Good gas
exchange, in tu~n, leads to improved productivity and greater
water loss.
