Short summary
We report on the net primary productivity of a biological soil crust from the Boodjamulla NP, Queensland. Metabolic activity lasted from September 2010 to mid-April 2011, referring to 23.6 % of the total time of the year. The first months of activity had a respiratory loss of CO2. Of the metabolic active period, 48.6 % were photosynthesis and 51.4 % dark respiration. Carbon gain was 1.72 g m−2 yr−1. The gas exchange pattern was divided into metabolically inactive winter and active summer month.
