Advanced Earth observation techniques in forest biodiversity and carbon sequestration mapping
Integrating multisource Earth observation (EO) data and methods allows studying forest biodiversity and carbon sequestration related questions at various spatial and temporal scales. We aim to develop and produce novel remotely sensed variables describing biodiversity and ecosystem properties using a multi-sensor approach. We utilize 1) optical satellite images (e.g. Sentinel, Landsat), 2) airborne laser scanning data, and 3) unmanned aircraft systems (UAS). Optical remote sensing covers large geographical areas at 10-30 m spatial resolution and temporal span of several decades. Laser scanning is a superb method to capture the 3D structure of forested ecosystems with sub-meter accuracy, and…
Hydrological disturbances and naturalness of aapa mires in Finland
Peatlands comprise one of the key elements in the boreal landscape. In Finland, almost one third of the land area is covered by different types of peatlands. Half of the Finnish peatland area has been drained, however, and in Southern half of the country, 75 % is drained (1). While drainage has increased forest growth, it has also caused manifold ecological consequences. For example, the state of the remaining undrained peatlands is affected by drainage of surrounding areas and fragmentation. The undrained peatland area in Finland consists of various sizes of peatland patches that often, at least in the southern areas, are not intact peatland ecosystems but only remnant patches of formerly …
