The Oldest tree they said is is about 4000-5000yrs old.(Prometheus)
"Rates of coral and coral reef growth have been studied by a number of investigators. Chave, Smith and Roy (1972) have analyzed some of the findings of other investigators and suggest net rates of growth of 0.8 to 26 mm/year. The net growth rate of a reef is the combination of total carbonate production less carbonate losses by biological, chemical and physical factors. Odum and Odum (1955) suggest a growth rate of 80 mm/year. Smith and Kinsey (1976), using an analysis of the CO2 system in seawater, suggest growth of 2-5 mm/year. Adey (1978) feels that this figure is too low for Atlantic reefs that must grow 2-3 times faster.
The figures given above contrast sharply with some figures based on actual soundings of reefs. Sewell (1935) reported 280 mm/year(about 1/4 meter in the Andaman Islands in the Bay of Bengal, and Verstelle (1932) reported a maximum rate of growth of 414 mm/year in the Celebes. This latter figure would allow for the development of the 1405 m of the Enewetak reef in less than 3400 years.The fastest growth rate reported for any coral is the staghorn species Acropora cervicornis . Lewis et al. (1968) found in Jamaica a maximum rate of 264 mm/year(about 1/4 meter a year). Shinn (1976) studied the growth of this species following destruction in a hurricane near Florida. He estimated linear growth rates of 100 mm/year".
