Wildlife
The 'Trowse Triangle' is a mosaic made up of a variety of habitats: derelict industrial sites, woodland and scrub, dry grassland, tall fen, dykes, grazing marsh, and the rivers.

Plants of the Wensum and Yare
The banks of the Wensum are mainly piled, and so provide an inhospitable habitat for wildlife. The depth of the river, and the disturbance created by boat traffic means it has little aquatic vegetation in the river. But on the edge of the Deal Ground there are many trees of significant landscape value, including Black Poplar and Weeping Willows.

The Yare upstream of the confluence has more diversity. The aquatic vegetation includes yellow water lily, and water starwort.

Nationally scarce plants such as Hoary Mullein, Green Figwort and Bee orchid grow on derelict sites.

Marshland and a rare snail
The large area of tall fen and dykes in the Carrow Abbey marsh is the only example of this habitat in the City. Although the plant diversity is relatively low, it supports an internationally rare mollusc - the Des Moulins' snail..

Birds, bats and otters
Barn Owls hunt over rough grassland in the Whitlingham area, while Kingfishers are common along the River Yare; and there may also be a breeding pair of Cetti's Warblers in the vicinity of the Deal Ground.

The rivers and scrub areas on the Deal Ground and Utilities sites are important feeding areas for Pipistrelle bats.

While otters are not currently frequent visitors to the area, improvements in the quality of the river habitat, coupled with the general upward trend in otter populations, make it likely that they will be seen more often there in years to come.
