There is a lake that runs behind the shopping centre between Xavier College and the Estate behind.
This is home to a host of waterlilies....blue, white, pink and red....and many waterbirds, some who migrate from overseas to visit the lake in seasons.
The lake is covered with weed which makes it look like a swamp rather than a beautiful lake.
I am sure it also harbors many mosquitoes in the stagnant areas.
However, the waterlilies are very beautiful....
The pond is also full of water lettuce....A free floating aquatic plant. Often escapes from aquaria. Looks like a very small open leaved lettuce or cabbage. Leaves pale green. Spreads from stolons which form numerous 'daughter' plants. It has a dense fibrous root system. Very quickly forms dense masses.
Problem: Mats can choke streams. Spread very rapidly and can deoxygenate the water, resulting in fish kills. Water losses increase due to transpiration. Creates a haven for mosquitoes.
