Figure 7.7
Examples of smooth, cyanobacterial biological soil crusts from western NSW, Australia: (a) characteristic pedicled
(concavely upward curled) cyanobacterial plates; (b) closeup of a water drop on one of the plates in A showing a tendency to water
repellency; (c) cyanobacterial plates in drought, showing a tendency to curl and separate from the underlying soil; (d) soil surface
with less strongly developed BSC of cyanobacteria and a greater proportion of inorganic seals; (e), (f) scarplets in cyanobacterial
crusts arising from wind abrasion during drought, with underlying silts exposed to deflation.
