Data are collected following the hiked path shown below and includes the immediate area.
One fertile flower (male or female), is all it takes to count a species in bloom.

We try to visit a lot of different areas, but areas with a better bloom may be visited more often.
It makes a huge difference if the bloom count is from a very dry badlands area, or from a place with a good rainfall or along a creek.

The data in the graph are averaged out over a couple of days, to show the actual daily bloom count in the graph, click on the legend on the right until only one is active (black).
With only one selected bars will pop up representing the daily bloom count.
