Abstract

For this study, researchers tested the effectiveness of seeding and fertilization treatments for increasing total live plant cover and reducing bare soil during the first 2 years following wildfire in dry mixed-conifer forests of north-central Washington state. Results suggest that fertilization treatments can increase the effectiveness of seeding treatments and stimulate regrowth of surviving native vegetation after fire, particularly in forest types with understory vegetation dominated by species that resprout. Yarrow seed was a surprising performer, especially in combination with fertilization. Effectiveness of treatments varied greatly depending on site characteristics that included elevation, precipitation and postfi re plant survival.
