The information board tells us:
"Where a river has been artificially straightened, as the Ravensbourne River here has, the river channel and banks become uniform.
A natural river contains many different habitats. The Parklands project (2011) aims to restore a variety of habitats in the river so that many different species can flourish.
Although prior to the restoration the river here was relatively clean, the health and habitat value have been improved through:
Removing concrete river walls and timber toe boards
Planting aquatic and marginal vegetation such as sedge and yellow flag iris
Creating deeper pools within the river for fish to live in
Creating shallow riffles for fish spawning and to oxygenate the water
Reintroducing meanders and narrower sections of river
Creating backwaters for fish spawning and shelter during high flows.
These changes will increase the populations of insects, fish and birds using the river as their home.
Lookout for species such as mayfly, stickleback and chub, grey wagtail and kingfishers.
River restoration can also help to reduce the likelehood of flooding in surrounding areas as creating sections of shallower river banks increases the channel's capacity to hold water."
The board is illustrated with sketches of plants, birds, fish and insects.
