In figure 2, you can see that year-2016 was a dry year and there was less biomass of annual plant growth. Why are wildflower blooms including California Poppy (Eschscholzia californica) plants more conspicuous and abundant in Southern California during dry years like 2016, than in wet years like 2017 when there is higher primary productivity and the annual brome grass plants (Bromus diandrus) are more abundant?.
