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.

The 2020-2021 bloom report:

Bloom prediction for the Anza-Borrego Desert:


Febr 21 2021:

This is one of the driest seasons we've ever seen.
The recent rain brought some rain, but a total of 0.5 inch isn't going to give us a good bloom season.
Only the Palm Canyon weather station reported 1.23 total for the season. That's still pretty low, but most likely enough for some bloom this spring.

We are predicting a below average bloom this season.


The best bloom, but still below average, Hellhole Canyon -> Palm Canyon following the mountain range north. Probably extending south up to Glorietta Canyon.
