Skogens helsetilstand overvåkes i Norge og rapporteres i en årlig rapport fra NIBIO. Bjørkemålerprosjektet bidrar med den nyeste status for bjørkemålere i Troms og Finnmark i årets rapport!
Salvage logging has been advocated as a means of speeding up the recovery of mountain birch stands that have been damaged by moth outbreaks, but empirical tests of the effects of logging have been missing. In a new paper in Forest Ecology and Management, we show that logging stimulates the growth and production of basal sprouts in the short term, but that these positive effects can be counteracted by ungulate browsing on the sprouts.
Continental scale travelling waves in winter moth: an evaluation of the evidence.
A recent paper claims the existence of one of the most large-scale travelling waves ever recorded for any animal population. In a new paper in Journal of Animal Ecology we address why conceptual and methodological pitfalls may have served to exaggerate or even impose the spatial patterns reported.
