The glorious thing about trees is it rains, the sun shines, they grow. If, when they are fully grown, the demand for lumber is weak, you don't cut, and they get bigger and more valuable. Come back in three years when the housing market has recovered, and you have an even bigger tree. Everything else has a negative-inventory cost.
The above—deferring cutting to some degree—is exactly what PCL has been doing for the past couple of years.
