About the Observation Time Plots
These plots show the elevations and times of year where the plant
has been observed.
The first set of plots to look at is the "All Zones" set. This plot
includes data from all latitudes. Each set contains three plots. On the
left is an elevation plot. The elevation plot shows how often the species
was observed at different elevations. The elevations go from 0 to 14,000 feet.
At the bottom is a plot that shows when the species was observed. The
large plot shows both when and at what elevation the species was observed.
White areas indicate that the species was not observed at these elevations
and times. As the species was observed more often the color changes from
light cyan to blue and then to red.
In addition to the All Zones set there are five latitude zone sets.
The time and elevation at which a species is observed sometimes different
at different latitudes. Zone 1 is the most northern zone and zone 5
is the most southern zone. When the species is not found within a latitude
zone the plots are blank. When a species is rarely found within a zone
the plots may have so little data that they are not accurate. When there
is little data the color of the large plot does not become red.
