Local provenances not best for afforestation with downy birch near the Keflavik Airport
In a 14-year trial near the Keflavik International Airport in Southwest Iceland, local provenances of downy birch were poorer in performance than many other southern provenances. For afforestation with downy birch, it is recommended that high-performing provenances be planted with initial artificial fertilization, accompanied by simultaneous seeding of lupine.
