Tree characteristics measurement

Objective
Measure and compare the diameter at breast height (DBH) and height of oak trees across sites.
Tools
Measure DBH using Haglöf Mantax Blue Klave calipers and determine tree height using a Suunto PM-5/1520 clinometer.
Data recording
Record measurements using the Field Maps app (ESRI), which will also geo-tag the location, date, and time of the measurement.
