Summary: 34 The Aquatic Gardener Volume 22 Number 4 35
leaved and emergent species all being
represented in the flora. The flora is
comprised of no less than 22 specialist
species growing in no other form of
temporary wetland (such as peat-lands
and sump-lands) in Western Austra-
lia, along with many cosmopolitan
species. Examples of the cosmopolitan
flora include species from Aponogeton,
Isoėtes, Marsilea, Myriophyllum, Pilularia
and non-native Callitriche and Cras-
up in the water column. In Californian
vernal pools, pH decreased to 7 while
CO2 rose to 200 µmol/L (9 mg/L). In
contrast, the plants consume all CO2
during the day so that the CO2 concen-
tration drops to almost zero while pH
may rise to 10 (Keeley & Zedler, 1998).
The dramatic changes in pH is caused
