Peat inversion is a management technique used to reduce emissions and retain carbon in cultivated peatland while allowing for effective forage production. Although maps and land registers document the presence of cultivated peatland that is suitable for peat inversion, these data do not cover all regions of interest. This study explores how an expert system and geostatistical modelling can be used to identify cultivated peatland suitable for peat inversion. The expert system proved to work moderately well for cultivable (but not for cultivated) peatland. Geostatistical modelling, using cultivable peatland as statistical support, gave good results in regions with large, continuous landforms. The results were less accurate in regions with rough, rapidly shifting terrain forms and where peatland was less frequent. The difference could be seen in the range and shape of the semivariograms. Geostatistical modelling can be used to identify cultivated peatland suitable for peat inversion in regions where the semivariogram shows a clear and well-defined spatial autocorrelation structure.

SUSDOCK: Sustainable control of docks (Rumex spp.) – Synergies of detection, mapping and innovative weed control
Broad-leaved dock (Rumex obtusifolius) and curled dock (Rumex crispus) are some of the most problematic weed species in grasslands worldwide; joined, in Norway and the rest of Northern Europe, by the far less studied northern dock (Rumex longifolius).

SUSDOCK: Bærekraftig kontroll av høymole (Rumex spp.) i norsk grovfôrproduksjon – synergier mellom kartlegging og innovativ ugraskontroll
Både ett-, to- og flerårige ugrasarter kan være utfordringer i eng og beite, men ofte er de flerårige mest problematiske. De flerårige deles i to grupper, stedbundne (eks. høymole) og vandrende arter (eks. kveke). I eng og beite er det spesielt vanlig med de stedbundne artene og mange betrakter høymole som den mest problematiske.
