Benthic microbial mats often occur in mangroves, especially in scrub or dwarf forests, where sufficient light penetrates to the soil surface. Gross primary production ranges from 6 to 15 mmol O2 m−2 h−1 across a range of light intensities for an average GPP of 12 mmol O2 m−2 h−1 in algal mats among dwarf mangroves on Twin Cays, Belize (Joye and Lee 2004).
