Water crassula, or water needlewort, is a bright green succulent native to Australia. The plant can grow tremendously fast and displace or overgrow other aquatic plants undesirably.
This is not good for water quality. It can lead to too little oxygen in the water, especially if the plant covers a large part of the ditch. Therefore, the Water Board takes immediate action to stop the plant from spreading.
Removing this exotic plant is not easy and must be done carefully. First, the plant must be protected. To do this, oil booms (floating, oblong cushions) are placed in the ditch. Plates are also placed along the edges of the plant and the plant is covered with netting. After this, a specialized company removes the plants from the water as quickly as possible. The plant remains are removed and destroyed. Controlling this exotic plant is difficult. Every piece of stem left behind can grow back into a plant.
