replacement for vegetation. Straw bales provide the same conditions and physical structure as natural vegetation, enabling the eggs to develop successfully. This method ensures that eggs and larvae are produced and that each river is a source of larvae. Exclusion of livestock and fencing of the bank-side vegetation is also an effective method to encourage regrowth of suitable vegetation. Restoration of the spawning habitat helps to maintain connectivity between larvae from different rivers during marine dispersal.
