A two-hour drive from Oslo in the southwestern part of Norway lies Siljan and the headquarters for Norway’s largest private forest owner Fritzøe Skoger.

Challenge

To manage 61,000 hectares of forest land is a huge undertaking especially with challenges connected to climate change, such as drought and bark beetles. Production forecasts for timber inventory are a huge part of Fritzøe’s forest management plan, and they need to be updated every six years with Field’s high precision data.

Solution

To reliably measure tree metrics such as species, height, volume and diameter, field personnel from Field acquire ground truth data from sample plots. These plots are used as a reference point for data acquired from high resolution airborne LiDAR scanning and orthophotography. With this data, Field detects every tree through the SingleTree method. The data is then summarized up to larger geographical areas known as forest stands which are used for management purposes.

Benefits

SingleTree data gives highly precise information on tree diameters and species/tree-health, which helps find dead trees in need of harvesting before the timber is destroyed. The customer is also able to search through the data to find specific diameters and lengths in demand from sawmills. They are also able to calculate future tree growth for every tree in Fritzøe’s inventory.
