9-(2-Phosphonylmethoxyethyl)-N6-cyclopropyl-2,6-diaminopurine (cpr-PMEDAP) as a prodrug of 9-(2Phosphonylmethoxyethyl)guanine (PMEG)

The mean annual litterfall at two dry woodland sites in central Queensland was 1129 kg ha–1 for an open E. populnea F. Muell. woodland (n = 2 years), and 2318 kg ha–1 for a woodland dominated by E. cambageana Maiden (n = 1 year). Leaves formed the largest component of total litterfall, which varied seasonally with a spring–summer maximum. Annual litterfall at these sites conformed with a pattern of decreasing litter production with declining annual rainfall, consistent with a range of eucalyptdominated communities.
