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 Pearce, 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 aesthetic value as they grow into substantial native bush areas. They're also great for the native bird life!"
Pearce'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 Shearman. "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."
