DNAire

The Aire, like many other city rivers has suffered from over 200 years of industry. Until the 1600s the river was used as a source of drinking water by the people of Leeds and Bradford. The growth of factories and cities soon made this a hazardous pursuit.

At the turn of the 1800s, Atlantic salmon could still be caught in the Aire below Bradford. However by 1825 the river here was nearly devoid of life and remained so for over 100 years.

It wasn’t just pollution that drove salmon from our rivers. Weirs that powered the mills blocked their migration from the sea to spawning grounds in the upper parts of our river.

Our project has five goals

Developing the Natural Aire (DNAire) aims to return Atlantic salmon to the river and connect local communities to their river to safeguard its future. Our river, the green and blue ribbon, that connects communities as it flows through the Aire valley can once again be the jewel in its crown.

To connect the ecology of the river

The ideal way to reconnect rivers is to remove weirs. However all four weirs in this project are listed and form part of our historic landscape. DNAire's fish passes will tackle the four largest weirs left on the river. These are at Armley, Kirkstall Abbey, Newlay and Saltaire.

Each will be a Larinier fish pass. In the base of these sit baffles that slow the flow of water through the pass. Larger fish are able to swim up the pass. Smaller fish are able to rest behind each baffle before they jump over the next one. The size of each weir means that resting pools are needed half way up.

DNAire reconnects 60km of river making habitat for fish to breed, feed and shelter. For Atlantic salmon, this means being able to swim upstream to spawning grounds in the shallow streams and rivers near Skipton. Their return demonstrates the outstanding quality of our river and signals a bright future for the Aire.

To connect diverse communities and organisations together

Volunteers make a huge difference to the Aire. Their work makes it pleasant place to visit by removing litter and caring for riverside paths to ensure access for all. Creates habitat makes space for nature and reduces flood risk through tree planting. Riverfly sampling helps us understand the health of the river.

This is possible due to funding from the Environment Agency, the Heritage Lottery Fund, Craven Council and Yorkshire Water.

To connect people to their rich heritage of the blue thread running through their communities

Visit the Aire on new walks under the banner Discovering the Natural Aire. We want people to explore their local river and be inspired to discover new gems along it. Local history groups and volunteers are sharing the heritage of our river.

To connect people to the impact of their own actions

DNAire is funding visits to primary schools to inspire the next generation to care for their Aire. By exploring the STEM skills used by professionals caring for our river we aim to create the next generation of River Defenders.

These visits are free to schools.

And to connect all of us to the wider world

Just as Atlantic salmon leave our river to start a vast migration to Greenland and back, we are connected to the wider world.

Your actions in Yorkshire can have global benefits.
