About the farm

Lying between 160 and 400m and with around 50 hectares of improved grass the farm carries a stock of:

  • 320 Scottish Blackface ewes
  • 400 mule ewes
  • 40 Luing suckler cows
  • 90 farmed red deer hinds

Hill lambs and suckled calves are sold as stores while crossbred lambs and red deer calves are normally sold as prime stock.

Why Trees?

Glensaugh’s woodlands expanded from around 17 to 70 hectares between 2008 and 2018 as:

  • areas of World War I felling were restocked 
  • other new woodlands were designed into the landscape

A further 100 hectares were planted in 2022, resulting in a displacement of some of the hill ewes.

All livestock will benefit from the shelter added to the environment. While the growing of timber and creation and linking of habitats add long term value to the site as a whole. 

Key messages from Donald

  • exclude livestock and control deer and rabbits
  • kill bracken and cut and kill whins [gorse]
  • plant densely and thin early
  • think long term; plant some oak trees every year and your successors will thank you for it
  • fell some trees every year; before they outgrow the sawmill or are blown down in the wind
