Minor tree trunk size variation occurs throughout the day and can provide insight into water use and water stress status. When certain characteristics of trees are available, change in tree trunk size can even be used to estimate above and below ground carbon sequestration. Commercial forest owners can also track the growth trends of their inventory and determine the time to harvest.
Sap flow monitoring using our advanced sensors allows us to gather hourly tree water consumption trends. When used with evapotranspiration (ET) data users can gain valuable insights into tree water need and alert to water stress conditions.
Sap Flow Rate (gallons/hour, liters/day)
Sap Flow Density (gallons/hour/cm3)
Sap Flow direction
Tracking soil volumetric water content using multi-depth sensors over a period and comparing it with sap flow, evapotranspiration and trunk size variations could provide valuable insights into hydrological dynamics in the soil-tree-atmosphere continuum.
Volumetric Water Content (VWC %)
For large areas of forests canopy coverage can be tracked with aerial imagery. Smaller forests can use drone-based sensors to estimate canopy health.
