Simple Forestry Densiometer
Simple Forest Densiometer
Project Developed by Brian Swanson User:Btswanso
- The forest densiometer provides a practical, objective way to measure the density of tree canopy. This tool removes all guess work out of determining canopy cover, which is a very useful metric for foresters and construction companies looking to predict how much foliage and tree removal must be done in an specified area.

- Align grid to the portion of canopy you wish to measure.
- Hold stationary, it is highly encourage to use a tripod with the associated mounts.
- Count the number of square holes filled over 50%, this number will be the density percentage of the canopy.
Bill of Materials
- The essential material needed to create this densiometer is 44 grams of PLA plastic. At an average price of $25 per kilogram, this part costs $1.10.
- This part has optional mounting 6 mm bolts. A pair of these approximately cost $1.50. A pair of matching 6 mm nuts will add an additional 25 cents to the bill.
Tools Required for Fabrication
- One 3-D printer capable of printing a 102 mm by 102 mm by 20 mm component.
Required Skills and Knowledge
- Ability to operate a 3-D printing device.
Printing and Assembly
- The print is a single component that takes approximately one hour and fifteen minutes to print. It requires approximately 44 grams of plastic.
- For mounting, simply place 6 mm bolts into holes on outside flanges and use nuts to fasten to whatever mount you desire.
- To remain accurate and objective, clean grid lines are a necessity. Proper calibration is a must, along with with minimal peel up. If peel up occurs, this may be limited with application of a glue stick to the print bed or use of a heated print bed.
- On the low end, a densiometer typically costs around $100. Thus, this print at its highest cost with attachments renders a savings of 97.15%.
