Threatened and uncommon bryophytes of New Zealand (2010 revision)

Figures & data

Table 1  Numbers of bryophyte taxa and entities listed in the reviews of 2002, 2005, and 2009, totals and by threat category.

	Year of review
Bryophyte	2002	2005	2010
Mosses	53 (10%)	63 (12%)	93 (19%)
Threatened	23	27	17
At Risk	28	31	57
Data Deficient	2	5	17
Liverworts	88 (15%)	157 (26%)	217 (36%)
Threatened	65	44	25
At Risk	11	51	79
Data Deficient	12	46	113
Hornworts	1 (8%)	1(8%)	2 (15%)
Threatened	1	1	0
At Risk	0	0	0
Data Deficient	0	0	2
Note: The percentages are the proportion of the total number of taxa that were placed on the threatened species list by the review of that year and are approximate. Most taxa in the ‘At Risk’ categories in 2002 and 2005 now fall into ‘Naturally Uncommon’ of Townsend et al. (2008) but the criteria for assigning a taxon to this category are largely unchanged.
