<p class="yiv9557263681MsoNormal"><span style="font-size:11.0pt;font-family:sans-serif;color:#1F497D;"> </span></p>
<p class="yiv9557263681MsoNormal"><span style="font-size:11.0pt;font-family:sans-serif;color:#1F497D;">Search Dr. Paula Pepper under growth algorithm and Allometric equations subjects and you might find many helpful research papers done
in US modeling the correlation between tree size (DBH, height) and Age. There were two researches completed by two Master of Forest Conservation graduates from University of Toronto in Oakville, Canada. One published in Urban Forestry and Urban Greening.
</span></p>
<p class="yiv9557263681MsoNormal"><span style="font-size:11.0pt;font-family:sans-serif;color:#1F497D;"> </span></p>
<p class="yiv9557263681MsoNormal"><span style="font-size:11.0pt;font-family:sans-serif;color:#1F497D;">However, as these correlations can be heavily altered by various factors (soil texture, volume, weather, available growth space, location,
etc.), your estimated age will not be as accurate as taking a core sample using increment borer. So depending on how accurate you want to be in your calculation/estimation, you might choose either the equations or increment borer. </span></p>
