Coastal Vegetation
|
The Coastal System in Hawai‘i
includes a variety of grasslands, shrublands and forests,such as this loulu palm forest on
the top of Huelo Rock.
Relative to the other ecological systems of the ecoregion, the remnants of coastal vegetation are typically isolated and not contiguous with the remaining lowland systems. In prehuman times, there would have been a transition between the coastal vegetation and the adjacent lowland systems, differing in both composition and structure. Coastal vegetation is typically both salt-tolerant and affected by frequent wave disturbance. There are a number of natural communities described within this system, including a variety of grasslands, shrublands, and a few forests. Biological diversity is low to moderate in this system, but some specialized plants and animals occur there, such as nesting seabirds and the rare Hawaiian shrub, ‘ōhai (Sesbania tomentosa spp.) More typically, coastal vegetation is low-statured, and tolerant of harsh, seaside conditions., such as this windblown strand at Kapapa, O‘ahu. |

The distribution of the Coastal System across the Hawaiian
High Islands
Ecoregion is depicted below in red with native ecosystems in green. The Coastal System near Ni'ihau occures only on Lehua islet (north) and Kaula Rock (south). The Coastal System on Kaho'olawe |
The
Coastal System on Hawai‘i Island occurs along several more remote
coastlines of the island.
The Coastal System on Maui
is very fragmented except for the remote north
coast of West Maui.
The Coastal System on Lāna'i is
heavily
fragmented, and has been degraded by feral ungulates and weed
invasions.
