Fig 1.
Number of records of all vascular plants and useful species in bioregions.
(A) Bioregion map of Colombia. (B) Number of records of all vascular plants (log-transformed) vs the mean vascular species richness (average of the number of all vascular plant species found in each grid cell of 10 x 10 km) for each bioregion. (C) Number of records of useful plants (log-transformed) vs mean useful species richness (average number of useful species found in each grid cell of 10 x 10km. In (B) and (C), points at the top right of the plot represent bioregions with greater numbers of records, but also with higher numbers of species after accounting for area, because mean species richness (species/cells ratio) represents the average number of species per unit area (in this case, 10×10 km grid cell).
Fig 2.
Mean species richness in the study area and in the surveyed areas: all vascular plants (A) and useful plants (B). Mean species richness in the study area was estimated as the number of species recorded in each 10 x 10 km grid cell within the geographic extent of Colombia; surveyed area richness was estimated within all 10 x 10 km grid cells with at least 1 record, and well surveyed area richness was estimated within all 10 x 10 km grid cells with ≥ 25 records. See Fig 1 for bioregion names and S2.5 and S2.6 Tables in S2 File, for richness values.
Fig 3.
Records of useful plants per category of use.
(A) Number of records of useful plants (log-transformed) vs the ratio of number of useful species per cell (species/cells ratio) for each category of use. (B) Number of records of useful plants (log-transformed) per category of use (axis x) and ecosystem (y axis). Dendrograms show clusters based on the number of records.

Survey completeness for all vascular (A) and useful (B) plants by bioregion. Percentage of 10×10 km well surveyed grid cells, defined as those with ≥ 25 observations, is calculated by bioregion.
