Easy evaluation of establishment treatments

The obvious approaches to comparing protabilit y of competing tree establishment techniques or treatments would require much data on growth, costs, and revenues. This in-depth knowledge is frequently unavailable or unreliable. A simple alternative is presented that of- ten can determine economic viability with little detailed information. Specically , assuming that an improved method shortens stand de- velopment time by years, it is shown that a break-even additional relative cost can be computed knowing just and the discount rate or internal rate of return.
