Table 1 The effect of fire on soil organic carbon (OC) and extractable total organic carbon (TOC) (0.5 M K2SO4) from restored and reference wetlands within the Hole-in-the-Donut, Everglades National Park, Florida, USA. Samples were collected two days (6 and 7 May 2010), 1 month (11 June 2010), and 1 year (25 May 2011) following the prescribed burn. (Average ± SE, n = 3, * = P < 0.05).
