Introduction
Gunningham Farms is one of seven successful Round 1 Integrated Farm Forestry Demonstration Sites receiving grant funding to develop landscape scale best practice integration of shelterbelts and woodlots into the agricultural landscape.
The Cunningham's are 5th generation dairy farmers are currently milking 700 organic cows and producing free range eggs through their nearly 3,000 laying hens.
Gunningham Farms have established 10.46 hectares of Pinus Radiata and 11.93 hectares of Eucalypt nitens at selected sites across the property. Strategically planting trees to maximise their full potential for shelter, biodiversity and aesthetics, Gunningham Farms urge others to get on board.
Gunningham Farms enlisted the services of professional forest consultants ‘Technical Forest Services’ to develop their plan.
Gunningham Farm is made up of 10 individual block plantings - 5 P.radiata shelterbelts (site 1), 2 P.radiata woodlots (site 2), and 3 E.niten woodlots (site 3).
“We are 100% convinced that this is appropriate for a lot of farms. We can already see where we would apply our learnings to our other dairy farms and where we would place additional shelterbelts” says Matthew.
All sites were planted in September 2021 by Mareeba Forestry, Ulverstone and received 20 grams of Multicote fertilizer on planting.
All sites have a stocking rate of 1,200 stems per hectare and all seedlings were sourced through Hills Transplants, Don.
