Or listen to selected sub-features
  • Q1 - The basic role of the timberland or forestland appraiser in helping investors making informed decisions (due diligence)
              Why forestland appraisals pose a challenge?
              Why timberland appraisals are unlike real estate appraisals?
              Why statistical inference introduces a level of uncertainty in the investment process
    For as time passes the data become archaic and have to be recalibrated which can introduce a certain amount of investment return volatility which is quite independent from the economics and the growth associated with the forests investment itself.

    Duration: 03:00 


  • Q2 - Quantifying this volatility - how much does it tend to be and what has it been historically?

    Duration: 05:00 


  • Q3 - Typically, what would implementing such a geographic information system (GIS) cost?

    Duration: 01:30 


  • Q4 - Why just using GIS is not a substitute to "boots on the ground" and why the two are actually complementary

    Duration: 03:18
