	\|Project summary=The River Rom, south of Roneo Corner, is heavily degraded. Straightening has resulted in the river losing much of the natural flow and habitat diversity that is needed to support rich biodiversity. It has also resulted in the loss of much of the river’s connectivity to its floodplain. This means the Rom lacks many of the associated wetland habitats that would slow the speed of destructive floodwaters and support the area's biodiversity.		\|Project summary=The River Rom, south of Roneo Corner, is heavily degraded.

-|Project summary=The River Rom is a tributary of the River Thames and forms the boundary between the east London Boroughs of Barking and Dagenham and Havering.
+|Project summary=The River Rom, south of Roneo Corner, is heavily degraded. Straightening has resulted in the river losing much of the natural flow and habitat diversity that is needed to support rich biodiversity. It has also resulted in the loss of much of the river’s connectivity to its floodplain. This means the Rom lacks many of the associated wetland habitats that would slow the speed of destructive floodwaters and support the area's biodiversity.
-Like many of London’s rivers, the Rom has suffered in recent years. Water quality has been impacted by sewage misconnections and overflows, whilst habitats for wildlife have been damaged by dredging and straightening of the river channel.
-The downstream reach of the River Rom (also known as the River Beam) flows through the eastern section of The Chase Local Nature Reserve (LNR). The Chase LNR incorporates nearly 50 hectares of meadows, ponds, marshes and woodlands and has been designated as a Site of Metropolitan Importance for Nature Conservation.
+The Rewilding the Rom project presented a rare opportunity to restore natural functioning to an urban river in London and in doing so, increase the rivers resilience to the compounding effects of climate change. Project aims are broadly fourfold; providing both offline and online flood storage, increasing resilience of downstream communities; diversifying the Chase Local Nature Reserves (LNR) habitat to support biodiversity; improving water quality of the Rom; and connecting communities to their river and environment. By providing these multiple benefits, this project demonstrates measures to address the biodiversity crisis are often closely intertwined with improving local communities' resilience to climate change.
-In 2021, funding from the Land of the Fanns Partnership Scheme allowed two seasonal wetlands (known as scrapes) to be dug on the Havering Side of the River Rom. These scrapes trap water on the floodplain during times of heavy rain and act as important habitats for wetland plants, birds, and other animals.
-In 2022, thanks to funding from the Kusuma Trust, the Mayor of London’s Rewild London Fund, and Essex and Suffolk Water, Thames21 will be working in partnership with The London Borough of Barking and Dagenham to further reconnect the River Rom with its floodplain, this time on the opposite bank. To do this, we breached a large flood embankment in three places and dug out three interconnected wetlands. In high flows, the river floods into this newly connected area of floodplain, creating an area of seasonal wetlands, rich in wildlife including frogs, newts, dragonflies and water birds.
+In 2021, Land of the Fanns Partnership Scheme funding facilitated the excavation of two seasonal wetlands (scrapes) on the Havering Side of the River Rom, in Grenfell Park to protect flood-prone properties downstream of the site. While the primary purpose of the scrapes is flood protection, they also provide habitats for flora and fauna. Flood modelling has been completed, showing that the scrapes, along with the other interventions, contribute to a reduction in flood risk to several downstream properties and the locally important Maylands Health Centre which currently serves 10% of Havering’s population.
