When the economy and the market look shaky … some investors have also been looking timber. The pitch is easy to like: a natural asset that grows on its own, matures into a harvest and can be cashed in all while you use it for recreation. Institutions have been buying timberland at a rate of one million acres per year, according to Bank of America, and some financial advisors say individual investors … are also taking a look at the asset class. But it is far from a rush, and investors who already own timberland caution that it may not be very profitable in the short term. …Financial institutions point to the asset class as one of interest specifically for the long-term investor. Ken Shepard, at Bank of America Private Bank said that timberland is not a tactical asset class that can be easily entered or exited in response to short-term market conditions.
