Sinclairs are a proudly Yorkshire business, and have been working in partnership with us to support the people, landscape and wildlife of the Dales for the last 19 years. 

Sinclairs have been a manufacturer of paper stationery since 1837. They are based in Otley on the edge of the Yorkshire Dales, and they work hard to support the stunning countryside that surrounds their factory. 

Partnerships that last  

For the past 19 years, Sinclairs have been partnered with us here at YDMT – supporting our work to keep the Yorkshire Dales a beautiful place for everyone to enjoy, whilst also supporting their own environmental and social responsibility aims.

They’re one of our longest standing business supporters, and we’re delighted that they’ve stood with us to support the people, landscape and wildlife of the Dales and surrounding areas.

In the last 10 years alone, Sinclairs have donated enough to plant more than 250 trees and to help more than 50 disadvantaged people access the Dales for health and wellbeing.

Over the years, they’ve joined us at a variety of tree planting events, come rain or shine they’ve supported our tree planting work and being a part of our efforts supporting the planting of more than 1.5 million trees in the Dales.

We look forward to continue working with them in the coming years.
