Funnily, my country has a similar story but with the opposite moral.

Scattered around my country you will see plantations of huge oak trees, all the same age. What gives? Well, in 1801 and 1807, my countrys navy suffered terrible defeats by the Brits as part of the Napoleonic wars. The fleet was eventually rebuilt, but that took cutting down many old oaks. Fearing that oaks are a rare resource that must be replenished, the king ordered the plantning of new ones, so that future generations could still build powerful battleships. Those oaks matured in the 1960s.

The moral of the story is that you can't actually plan 150 years into the future.
