VEGETATED
& COMPLEX RIPRAP APPLICATION
Vegetated
riprap incorporates a combination of rock and native
vegetation in the form of live cuttings. These can be
planted in conjunction with the placement of rock used
to armour the banks of watercourses or redirect flows.
Establishment
of native vegetation will improve fish habitat by creating
shade, cover and an input of small organic debris to
the stream. In most cases it will negate the need for the regulator to require habitat alteration compensation. It will also provide added bank protection
through development of root mass. An additional benefit
of this combined technique is a potential supply of
fodder for local animal populations.
Adding
vegetation to riprap provides a softer more natural
appearance to the installed rocks.
