	Lord Howe Island - Wikipedia, the free encyclopedia
		Lord Howe island is a distinct terrestrial ecoregion, known as the Lord Howe Island subtropical forests.
		Lord Howe Island was never part of a continent, and all of its flora and fauna colonized the island from across the sea.
		The Lord Howe Swamphen or White Gallinule (Porphyrio albus), the White-throated Pigeon (Columba vitiensis godmanae), Red-fronted Parakeet (Cyanoramphus novaezelandiae subflavescens) and the Tasman Booby (Sula tasmani) were eliminated by settlers during the nineteenth century.

	Lord Howe Island, Tasman Sea, Australia (Site not responding. Last check: 2007-10-08)
		Lord Howe Island is the erosional remnant of a 6.9 million-year old shield volcano.
		The island is 375 miles (600 km) east of the continent of Australia and near the boundary between the Lord Howe Rise and the Tasman Basin.
		The Lord Howe seamount chain, defined by coral-capped guyots, continues to the north for 600 miles (1000 km) and is probably the result of the Australia plate moving northward over a stationary hot spot.

		The waters of Lord Howe Island are renowned for their clarity, relatively high coral and algae cover and high biodiversity due to the combination of tropical and sub-tropical fauna.
		Lord Howe Island is regarded as an excellent example of the evolution of a volcanic island (guyot) formed on an oceanic ridge.
		The hydrological regime of Lord Howe Island is on a boundary between tropical (Coral Sea) and temperate (Tasman Sea) water masses, commonly referred to as the Tasman Front.

	Terrestrial Ecoregions -- Lord Howe Island subtropical forests (AA0109)
		Lord Howe Island is unique among inhabited Pacific islands in that less than 10 percent of the island has been cleared for human use.
		Lord Howe Island is located approximately 700 km east of Australia and 1,350 km northwest of New Zealand (31 S, 159E) on the submerged Lord Howe Rise.
		Lord Howe Island is largely covered with rainforest, although there are areas of scrub, grassland, and clearings in the lowlands and on the cliffs.

	Geoscience Australia - Lord Howe Rise
		The Lord Howe Rise (LHR) is a frontier area that extends from southwest of New Caledonia to the Challenger Plateau, west of New Zealand.
		The LHR is underlain by continental crust that detached from eastern Australia during the margin breakup that led to the formation of the oceanic Tasman Basin from 85-52 Ma.
		The central rift province, adjacent to the Lord Howe Platform, is characterised by a series of poorly defined basement blocks, normally down-faulted to the west, with 2-4 km of Upper Cretaceous and Cainozoic syn and post-rift section.

	Plate tectonics: a paradigm under threat
		Interest was revived in the early 1950s with the rise of the new science of paleomagnetism, which seemed to provide strong support for continental drift.
		Although a general trend is discernible from younger sediments at ridge crests to older sediments away from them, this is in fact to be expected, since the crest is the highest and most active part of the ridge; older sediments are likely to be buried beneath younger volcanic rocks.
		Plate tectonicists admit that it is hard to see how the subduction of a cold slab could result in the high heat flow or arc volcanism in back-arc regions or how plate convergence could give rise to back-arc spreading (Uyeda, 1986).

		Europeans apparently discovered Lord Howe Island when the island was sighted in 1788 from the British colonial naval vessel HMS Supply, en route from Sydney to the penal colony on Norfolk Island.
		Pigs and goats, which were introduced to Lord Howe Island for food, later went wild and caused extensive vegetation and habitat changes, threatening populations of native species.

		The Gascoyne Abyssal Plain is separated from the Argo Abyssal Plain to the north by the Roo and Joey Rises, and bounded to the east by the Platypus Spur and the Exmouth Plateau.
		The middle Lord Howe Rise continental block east of Tasmania moved together with Tasmania along an incipient NE-SW oriented strike-slip fault that remained active during the 90-52 Ma opening of the Tasman Sea.
		Because the record of the pre-anomaly 33o tectonic history is sparse, the pre-breakup configuration is constrained by strike-slip faults (as in the case of the Lord Howe Rise and the Dampier Ridge) and failed rifts (between Tasmania and the South Tasman Rise, Tasmania and the East Tasman Rise, Gilbert Seamount Complex and the Challenger Plateau).

		The region is bounded on three sides by oceanic basalt crust of Late Cretaceous and Palaeogene age (Figure 2) that formed during seafloor spreading between 80 and 20 m.y.a., as the Lord Howe Rise broke away to the east and Antarctica moved relatively to the south.
		The oceanic abyssal plain west of the South Tasman Rise is very lightly sedimented, and the swath-mapping shows that the surface topography mimics that of the oceanic basement.
		East and south of the rise lies a pile of sediment more than 1000 m thick, which was probably swept from the rise by currents.

		This is Lord Howe Island, by far the southern-most coral reef in the world.
		You say that in #127 you are questioning whether coral larvae could have journeyed to Lord Howe Island since the last ice age, and then specify that this be done "from scratch", which you then define as being restricted to the species that "survived the last ice age in Lord Howe".
		You are right on this one -since I mentioned I wanted to keep "coral larvae coming again to Lord Howe" outside the scope of my answer, I should have used an extended scope for "from scratch", including also the coral that eventually arrived there.

		The later rise of the angiosperms to 85% of the fossil species [Axelrod (1966)] {but not necessarily 85% of the area covered} may have been assisted by the appearance of Coptotermes in the rain forest, which insect also uses live wood, toward the end of the Cretaceous in the Northern Hemisphere tropics.
