  1. Use herbicide to control bracken

    A replicated, randomized, controlled, paired study in 1992-1995 in a former heathland invaded by bracken Pteridium aquilinum in the Wirral, UK (Snow & Marrs 1997) found that spraying with herbicide to reduce the cover of bracken did not increase the number of common heather Calluna vulgaris seedlings relative to cutting. In eight of eight cases plots that were sprayed with herbicide did not have a significantly higher number of common heather seedlings than plots that were cut (herbicide: 8-20 seedlings/m2, cut: 1-76 seedlings/m2). Three 15 x 5 m plots were cut once a year, three plots were cut twice a year, and three plots were sprayed with the herbicide asulam. Cover of plants was assessed in three 1m2 quadrats in each plot in September 1993 and June 1994.
