The added carbon accumulation, as the forest regime regenerates and shifts from coniferous to deciduous trees-that's like putting the parking brake on while driving the bus, says Johnstone.

Fortunately they prefer the succulent broad-leaved triticum and other woodland grasses to the silky species of the meadows, and therefore seldom bite them or set foot on them.
