Name:
Cocos nucifera / Pennisetum polystachion - Pennisetum purpureum Ruderal Scrub & Herb Coastal Strand Group
Reference:
NatureServe Biotics 2019
Description:
This ruderal strand group is restricted to the shoreline and the zone immediately back of it where sites are strongly influenced by surf, wind and salt spray and where the vegetation tends to be sparse and patchy. Vegetation includes succulent herbs, low wind-sheared shrubs, grasslands, dry shrubs and grasses or taller shrublands, often with scattered trees, especially <i>Cocos nucifera</i>. The vegetation is strongly dominated by non-native species. Characteristic species include <i>Atriplex semibaccata, Vachellia farnesiana, Batis maritima, Cocos nucifera, Coccinia grandis, Cynodon dactylon, Kalanchoe pinnata, Lantana camara, Leucaena leucocephala, Melinis repens, Morinda citrifolia, Pennisetum ciliare, Pluchea indica, Prosopis pallida, Sphagneticola trilobata, Tetragonia tetragonioides, Thespesia populnea, Tournefortia argentea</i>, and <i>Verbesina encelioides</i>. Stands occur along disturbed coasts of the Hawaiian Islands and are restricted to the shoreline and the zone immediately back of it. Elevation is generally below 30 m. Sites may be rocky shorelines or sandy beaches, some with adjacent dunes or low alkaline flats above the saturated zone and behind the high-tide mark. Climate is warm, tropical. Annual precipitation ranges from over 3500 mm for wet strand, down to 1200 mm on seasonally mesic sites, and less than 1200 mm for dry strand. Substrates are variable, ranging from sandy beaches to cobbly shores, derived from volcanic tuff, recent lava flows or old disintegrating lava (basalt), or raised coral beds (limestone).
