This study tested the hypothesis that rates of canopy recovery are substantially less in turf-dominated habitats relative to canopy-dominated landscapes. It also tested the hypothesis that canopy recovery would be enhanced within turfed landscapes if turfs were removed from the spaces between remnant forests.
Site Selection Criteria:
The selected site had historically large kelp forests that have since been lost. Whilst much of the original kelp forest has been replaced by turfed habitat, small remnants of forests are common.
Cause Of Decline:
On temperate coasts, there is concern about the permanent replacement of perennial canopy-forming algae (i.e. structurally complex and highly productive habitats), with opportunistic taxa such as filamentous turf-forming algae (i.e. comparatively simple habitats). In this habitat, turf algae was experimentally removed to simulate a disturbance.
