Chris,A boat cut through a swath of these lovely water flowers, leaving behind in its wake, these broken beauties, left to drift away util they too become a part of the muck at the bottom of the lake.
You would be surprised. One needs one root fragment on the stem and one meristem in the leaf axis. The photosynthesis is still active. Those leaves that got whacked the most are one way dead. I see so e possible root remnants. Life can be tenacious.Not when their are ripped into pieces.
Tom,I live in a community inter-twined with/by 8 lakes. They are home for water birds, turtles, native fish, barramundi, finches, parrots, snakes, the occasional croc. The plant life is also native and flourishes in the warm water.
Each year the Parks and Wildlife people will have the lilies and other water plants ‘harvested’ to allow light to enter the water and oxygen to dissolve readily. This prevents fish kills and dense algal growth.
They literally mow the water flora. They use a barge with a huge cutter at the front. Then the cut reeds are raked up and composted at the local dump.
Within weeks of this happening, the lillies and other water plants start appearing on the surface.
These plants can cope very well with damage since the growth comes from the bottom of the lake under the mud.
The lakes are not for recreation . No boats, swimming etc. they are for the birds and bees and the community to look at.
Without the regular cutting of plants the lakes would soon become lifeless swamps of choked waterway and devoid of anything but algae and rotting vegetation with a few worms and bacteria.

Jeez Chris, you know you’re in the tropics when you have to mow your lawn...and your swamp.I use a similar weed mower when the weeds begin to choke the area around my boat...nasty things will clog a propeller in no time. It's basically just an underwater scythe.
