Using satellite-retrieved soil moisture data to model the decay risk of in-ground timber
2022 - IRG/WP 22-20689
Satellite-derived soil moisture data from the Soil Moisture Active Passive (SMAP) was extracted for a 9 x 9 km point grid over Europe. The data was then used as input to a dose-response wood decay model based on terrestrial microcosm (TMC) tests. The resulting hazard map plotted dose as an indicator of in-ground wood decay based on differences in annual temperature and soil moisture characteristic...

Phytosanitary heat treatment of wood in a laboratory drying oven and, in a pilot-scale kiln using the house longhorn beetle (Hylotrupes bajulus) larvae as a model
2024 - IRG/WP 24-20722
International trade in wood products brings the risk of the movement of tree pests which can cause devasting ecosystem and economic damage. International phytosanitary guidelines were created to help countries that import wood products. Import requirements intend to minimize pest spreading. Thus, the ISPM 15 (International Standards for Phytosanitary Measures No. 15) which specifies the “Regulat...

Changes in decay risk of wood in ground contact over Europe, from analysis of historic climate conditions
2024 - IRG/WP 24-41008
Changing climate conditions will affect global temperature and precipitation patterns, shifting some geographical areas into states that are more suitable for fungal wood decay. Climate normals, which are taken over a 30-year period, capture vast spatial and temporal variations in these conditions and comparing these can show changes over time. Importantly, being able to identify locations that ha...
