"One is to help prevent erosion on steeper faces and near waterways. Allowing natural regeneration, along with some strategic planting, helps prevent slipping by increasing ground cover and root structure. It's also beneficial to have unsafe areas for livestock fenced off and stock excluded, as well as being of ascetic value to the property over time."
The work has also opened up opportunities. He's already diversified into beekeeping for manuka honey production, and sees the possibility of earning carbon credits for his retired areas and poplar plantings.
The benefits don't end there.
"With the STRESS areas retired, we can concentrate on improving fertility and production on the more productive land," says Roger, who has maintained his stock numbers at 4000 Romney ewes and 500 Angus breeding cows, with brassica crops and regrassing to finish lambs and bulls.
"Generally, maintenance on STRESS areas is low and we can still use access tracks through them."
He says the retired areas have been beneficial in creating natural buffer areas between blocks and next to waterways.
"In general, I think the retired areas will add value to the property over time, with the benefits of soil conservation and ascetic value as they grow into substantial native bush areas. They're also great for the native bird life."
Roger's efforts demonstrate that a sustainable land management approach is a winner in the hillcountry, says the Council's Land Services Manager, Don Shearman.
"It really does sustain the land — as well as the environment, and as well as the livelihoods of farmers like Roger," says Don. "The bottom line is that without soil, you can't grow grass.
"And the impact of hillcountry erosion has already been seen in major flooding events, while the sediment also degrades the health of waterways. Freshwater quality has become an increasingly important priority, regionally and nationally, so doing the right thing, as Roger has, is in the interests of farmers themselves as well as everyone else."
STRESS assistance is sourced from MPI's Hill Country Erosion Fund. As well as administering STRESS, Taranaki Regional Council also works with hillcountry farmers to produce free, individually tailored farm plans — either covering an entire property, Agroforestry Plans for establishing exotic or native plantation forestry, or Conservation Plans for specific areas of concern.
