Identifying Spruce Beetle Infestations Earlier Using Satellite Data

Harwell Campus, Oxfordshire, UK, 25 October 2018.

Spruce Beetles have become an increasing threat to the forestry industry over recent decades. Outbreaks used to be episodic but are now at epidemic levels in many parts of the world.

Once an infestation is identified, it is a race against time to contain the outbreak and salvage affected timber before it loses its commercial value.

Rezatec, leading providers of geospatial data analytics for the forestry sector, have produced a guide: ‘Identify Spruce Beetle Infestations Earlier Using Satellite Data’, which examines how beetle infestation affects timber quality over time, the challenges of identifying infected trees using traditional methods, and how multi-spectral satellite data can help to identify affected stands before they lose much of their commercial value.

By assessing multi-spectral bands such as infra-red to measure more subtle indicators of plant health, infestation can be detected up to three months earlier than when using purely visual methods.

Tim Vallings, Vice President, Global Resources at Rezatec commented: “Identifying diseased trees as early as June allows foresters to validate, plan and fell in the same year, and thereby sell the timber as much as a year earlier than traditional methods allow to obtain a better market price.”

The key benefits of using satellite data to identify Spruce Beetle infestations are:
• Regularly monitor subtle changes in tree health across entire forest
• Identify outbreaks up to three months earlier
• Salvage and sell timber up to one year earlier

Rezatec have produced a number of other guides relating to the application of satellite data for effective forest management including: tree species identification from space and a comparison of the benefits of satellite and lidar data for forestry analytics.
