Mangareva Island. This island was not used in analyses of change in naturalized plants through time, because the date of most recent plant collections could not be determined.


Nauru Island. 1933 (22), 1981 (84), 1988 (85).


New Zealand Islands. 1853 (61), 1867 (169), 1906 (528), 1925 (576), 1940 (593), 1999 (2065). The large size and topographic complexity of New Zealand (relative to other islands) creates greater uncertainty about whether particular exotics are naturalized or not in individual time steps. Consequently, data values were taken directly from the literature and range-through values have not been calculated (see Methods in the main text). Data from 1940 were excluded from our analyses because there is a large set of species that may or may not have been naturalized at that time, but data from the other time steps were used. Note that some additional dates are available for a subset of the vascular plants (the non-monocots), but these data were not used here, as our analyses were focused on vascular plants.


Norfolk Island. 1805 (5), 1902 (108), 1912 (115), 1994 (246).


Pitcairn Island. 1991 (40).


Tabuaeran (Fanning) Island in the Northern Line Islands. 1874 (3), 1924 (10), 1972 (19), 1983 (25). The Northern Line Islands, as a set of four islands (Table 5A.1), were used for Fig. 5.2 and the multiple regression analyses. Tabuaeran Island, which has a more complete temporal record, was used for analyses of change through time: Table 5.1, Figs. 5.3 and 5.4.


Tristan da Cunha Island. 1817 (1), 1852 (11), 1873 (14), 1885 (15), 1904 (26), 1909 (34), 1910 (36), 1925 (37), 1934 (38), 1937 (51), 1938 (57), 1954 (62), 1955 (63), 1957 (65), 1962 (66).
