Sow seeds Shrubland and Heathland Conservation

A replicated, randomized, controlled study from 2009 to 2012 in a sagebrush ecosystem that had previously been burnt in Oregon, USA (Davies et al. 2014) found that sowing grass and sagebrush Artemisia tridentata seeds led to increased grass and sagebrush cover. After three years, sagebrush cover was higher where grass and sagebrush seeds were sown (6%) than where grass seeds or no seeds were sown (both 0%). Grass cover was higher in blocks where grass seeds (8%) or grass and sagebrush seeds were sown (6%), compared to blocks where no seeds were sown (4%). Fifteen 15 m x 30 m plots were randomly assigned to be sown with perennial herbaceous plant seeds, sagebrush and perennial herbaceous plant seeds, or no seeds. Vegetation cover was measured annually between 2010 and 2012 using sixty 0.2 m2 quadrats.
