Well, we've been in class tier for seven years now, and we were in tier co-valentir Cymyn before, so we've got a history of being in environmental schemes. Class tier is an important part of our business. The income we get from class tier is part of our sustains, our business. So we've got about six projects running year at the moment from ffensing out 25 acres of existing woodland, regenerating that woodland, cutting off hedges and replanting them, make wildlife corridors from one end of the farm to the other. So over the last seven years we would have planted about 8,000 trees. We've also got some semi-improved grassland where we're looking to increase biodiversity and species of fauna to return that were here previously, and we combine that with more areas of land that we farm more, slightly more intensively for food production. So it's a combination of environmental work and food production working together and targeting certain areas of the farm differently to achieve both objectives. Well, y wahaniaeth arrewn wedi wneud yw mwy o bai o diversity ar y ffarm, so ni weld species o aderun, a ni sewn ni wedi weld amlyneddau.

The investment of Glastir in the rural community sustains a lot of these hill farms. A lot of hill farms in the area would be in Glastir, and the income from Glastir is an important part of sustaining their business. And it's important to remember that the Welsh language is based around these hill farms. Virtually all the hill farms in the area are first language Welsh, so the rural community as we know it and the Welsh language as we know it is sustained by these family farms.
