The British Columbia Conservation Data Centre (CDC) is currently tracking >600 rare native vascular plant taxa in the province. This overwhelming number, about 25% of our entire native flora, requires careful prioritization to maximize the efforts of a limited staff and a restricted budget. The highest priority goes to the 241 Red-listed plants, whose habitats are either threatened or endangered. Little is known about the abundance and condition of populations of these critical taxa, and inventory is therefore much needed. In recent years, intensive field surveys have vastly increased the knowledge and occurrences both for critical areas and specific taxa. In many cases, the CDC database has increased tenfold for these areas and taxa. This inventory has also enabled a number of taxa to be de-listed.
