Table 2 Presence (percentage of samples) and density (number of plants per 1000 m2) of abundant taxa in controls (Cont) and masticated (Mast) fuel treatments (n = 149) in southern California, USA, chaparral (2011 to 2012). Recruitment is facultative seeding (FS), obligate resprouting (OR), or obligate seeding (OS); status is native (N) or non-native (NN).
