Albedo in boreal forest

Albedo in boreal forests serves as a strong climate forcing which potentially can offset the climate impact of carbon sequestration. To assess the albedo effect from different types of forest management in the Nordic countries, fine-resolution albedo products are needed to account for the patchiness and heterogeneity typical present in this biome. There are several albedo products available today. However, most of them have a spatial resolution ranging from approximately 0.25–20 km.

The overall aim of the project “Albedo in boreal forest” is to develop an estimation approach for retrieving fine-resolution albedo to evaluate the albedo effect in managed versus unmanaged forest.

Mapping of drought stress in spruce using remote sensing

Spruce is an economically important tree species for the forestry industry in Norway. In recent years, with frequent periods of drought, it has been observed that spruce in several areas is susceptible to drought stress, which can lead to the death of trees either as a direct consequence of the drought or indirectly following bark beetle attacks. Therefore, there is a need to develop a mapping system that can provide a quick overview of the degree of drought stress for spruce stands within a given planning area.

SmartForest

The primary objective of SmartForest is to improve the efficiency of the Norwegian forest sector by enabling a digital revolution transforming forest information, silviculture, forest operations, wood supply and the overall digital information flow in the sector.

NMBU is leading the work packages 1, 5 and 6 (Fig. 1).

PRECISION

«Precision forestry for improved resource utilization and reduced wood decay in Norwegian forests (PRECISION)»

PRECISION is an integrated project that addresses root and butt rot (RBR), the largest source of biomaterial and value loss in the primary production of the Norwegian forest sector. Even a small improvement in the information of the geographical location of RBR can lead to a very large financial gain for the forest sector.

PRECISION consists of a multidisciplinary research consortium spanning the fields of robotics and forest technology, remote sensing, pathology, silviculture, forest management planning, and economics. The consortium includes researchers from Norwegian research institutes and universities in partnership with leading international scientists. The industrial partners are an integral part of the project – the PRECISION industrial partners are responsible for more than 80% of the annual harvest in Norway’s forests.

PRECISION aims at improving the carbon footprint and hence the overall sustainability of the Norwegian forest sector. RBR has a negative impact on the carbon footprint of the forestry sector as it reduces tree growth, increases tree mortality, and reduces the yield of saw timber that can substitute building materials with long lifetimes.
