Right. Pinus radiata (Monterey Pine) is native to California, but really has a narrow native range within the state. In the mid-1960's they became popular as ornamental and landscape trees due to their relatively fast growth rate. The problem is, that outside their native range of the central California coast, they become unduly stressed and are prone to several pests (mostly beetle larvae) that are attracted to any pruning cut made in the growing season like a shark to bloody chum. These pests can smell sap flow in Pinus radiata from 30 miles away.
The lumber and pulp plantations I saw in Central Chile were these Monterey Pines and Eucalyptus globulus. The forestry plantation methods I saw reminded me a great deal of those in Bavaria. It would not surprise me that Chilean forestry methods were learned from German mentors. Trees are planted on uniform centers and lower limbs are bucked up to divert root carbs to the highest terminal growing shoots, promoting faster height and more uniform trunk diameter. It also minimizes knots to some degree, but Monterey pines have a lot of secondary branches and there will always be lots of knots, except in the very heart.
In my opinion Chilean foresters are flirting with crop disaster in choosing these two species. They are the most pest-infested tree species in California, whose climate and geology is very similar to Chile's. Such mono-cultures are like big petri dishes waiting for a pest to get established and wipe out the crop. These two trees may be the fastest peso, but growing them is playing biological musical chairs. One day the pests will arrive and many millions of trees will have to be quickly harvested at a loss, mature or not.
This is why I asked before about Redwoods. I have grown them professionally for 25 years, and there are a few sterile cultivars that I believe would perform well in Southern Chile. I think between their pest resistant nature, the amount of annual rainfall in the south, and my particular cultural tricks, I could grow California Redwoods faster to market than the Monterey Pines now being grown. Of course, these would be mostly for the domestic dimensional lumber market, as they would be too valuable to export as pulp.
There are a lot of older homes with traditional Alerce shingles that will eventually need replacing, and the Alerce tree is very slow to grow. The old growth is now protected (for the most part). Redwoods look and perform about the same in the mill, and in the builders' hands. Besides, I know Charles is eager to strap on the old tool belt and build a beautiful new "Chilean Redwood" deck.
