First Principles Thinking: Biological Assets
B is correct. Timberland is a unique asset class defined by biological optionality. First, the 'factory' concept means the asset manufactures its own inventory via photosynthesis—trees grow volume regardless of the economy. Second, the 'warehouse' concept means you are not forced to sell; if lumber prices crash, you store the value 'on the stump' where it continues to grow. Finally, the geographic concentration of investable private timberland is historically centered in the US (approx. 50%).
Statement 3 is incorrect (making A, C, and D wrong): Timberland returns are driven by biological growth and local land values, not corporate earnings. Therefore, they historically show very low or zero correlation with public equities, which is their primary value for diversification.
