The contributing editor to Money Morning explains, "In the modern era, inflation has never been a match for timber. On average, the price of harvested lumber itself has risen more than 5% annually over the past 100 years.

"Since 1910, the value of timberland as an investment has risen faster - and with less volatility - than stocks as measured by the Standard & Poor's 500 Index. Here's a trio of stocks to benefit from this trend.
