DynaRoot Root Testing System

 

The stability of urban trees is a key question that affects everyone. Diseased and unstable urban trees pose much risk for everyone, and are a serious liability for municipalities in case of an accident. Tree stability assessment is therefore of the utmost importance. At present, there is only one accepted method for tree stability assessment. The pulling test, while well established and accepted, has several drawbacks, both in terms of reliability and ease of use.

 

Usage Instruction

  1. Assemble the anemometer tower in the vicinity of the tree(s) to be assessed. Attach the anemometer on the top, and erect the tower. Wind velocity readings are sent to, and data is collected at the instrument box located at the bottom of the tower.
  2. Start recording data by pressing the START button located in the instrument box.
  3. Mount the inclinometer on the root collar of the tree to be assessed.
  4. Start recording data by pressing the START button located on the side of the instrument box.
  5. Repeat the previous 2 steps if you have more inclinometers and want to assess multiple trees.
  6. Record data for at least 3 hours (the longer the better).
  7. After the recordings are finished, transfer the acquired data to a PC by removing the internal SD card or by switching the instruments to Wi-Fi mode.
  8. Load the data into the DynaRoot evaluation software and calculate the safety factor.
