  1. Use prescribed fire to maintain or restore disturbance

    A replicated, controlled, before-and-after study in 1994–1998 in a bog in New Zealand (Norton & De Lange 2003) found that burned plots contained a different plant community to unburned plots, with greater plant species richness, diversity and cover. Before intervention, all plots contained a similar overall plant community. After four years, burned and unburned plots contained different communities (data reported as a graphical analysis; difference not tested for statistical significance). Also, burned plots experienced significant increases in foliage cover (from 103% before burning to 171% four years after), plant species richness (from 8 to 14 species/4 m2) and plant diversity (data reported as a diversity index). In unburned plots, these measures declined (cover: from 104 to 100%; richness: from 9 to 6 species/4 m2). In July (winter) 1994, twelve 2 x 2 m plots in a fire-suppressed bog were burned. Twelve control plots remained unburned. Cover of every plant species was recorded in all plots immediately before burning, and at intervals until September 1998.
