Crane | ind | NH/ UP/ HO/ FHi MARQUESAS: Ua Pou (9.40°S/140.08°W); lies 300 kilometers from the Marquesas Fault Line hot spot, vocanic island of 5.61 million years, 105 sq kilometer area, maximum altitude of 1203 kilometers. Ridge above Anakooma river and below Oave, 2000-2400 ft elev., dominated by Pandanus tectorius, Freycinetia impavida and Dicranopteris linearis with Hibiscus tiliaceus dominating the forests below ridge. Common native associates include tree species such as Weinmannia marquesana, Ficus prolixa var. prolixa, Metrosideros collina, Crossostylis biflora, Macropiper latifolium, and Cyclophyllum barbatum. Common native grasses include Miscanthus floridulus, Centosteca lappacea, and Leptochloa marquisensis. Peperomia blanda is common along rock outcrops and other less common herbs and trees include Procris pedunculata, Adenostemma viscosum, Boehmeria virgata, Ixora, and Morinda myrtifolia. Pteridophytes of the area include Asplenium affine, Asplenium quaylei, Asplenium tenerum, Diplazium harpeodes, Blechnum capense, Blechnum vulcanicum, Doodia marquesensis, Cyathea affinis, Paesia rugulosa, Arachniodes aristata, Polystichum marquesense, Tectaria jardinii, Elaphoglossum marquisearum, Elaphoglossum tovii, Trichomanes, Lindsaea propinqua, Sphenomeris chinensis, Lycopodium cernuum, Angiopteris evecta, Ophioglossum pendulum, Belvisia mucronata, Selliguea feeioides, Adiantum trapeziforme, Pteris comans, Selaginella arbuscula, Amphineuron opulentum, Chingia longissima, Coryphopteris quaylei, Tmesipteris sp. nov., Antrophyum subfalcatum, and Haplopteris elongata. 50-70 Tahitian petrel were observed circling around Oave and ca 20 individuals of the Marquesan fruit dove were observed passing over the ridge between drainages. The main threats to this ecosystem include habitat degradation and destruction by feral pigs, catastrophic extinction through environmental events, predation by rats that eat seeds, competition with non-native plant taxa such as Psidium guajava, Coffea arabica, Oplismenus compositus, Conyza bonariensis, Cordyline fruticosa, and Zingiber zerumbet some of which possess the ability to spread rapidly and cover effectively large areas in the forest understory, possible land slides, and for the rare species, reduced reproductive vigor as the result of limited numbers of existing individuals.
