San Jacinto Mountain Species in Bloom Above 6500 Feet Elevation: 2011

Species in Bloom On Each Trip

Introduction

This page reports the number of species seen in bloom above 6500 feet elevation on each hike at San Jacinto Mountain, along with our best-guess estimate of the total number of plants in bloom for each species.

It is important to note that these numbers were compiled only incidentally to our main botanical goals for each trip. Hence few of the numbers of plants in bloom come from actual counts, since we rarely made a point of actually surveying intently for how many plants of each species were in bloom.

Our procedure was to note each species in bloom when encountered for the first time. Most of the time, near the end of each hike, we make an estimate of how many plants we remembered seeing in bloom for each species. Sometimes, there isn't time to make those estimates during the hike, and they are made a day or two after the hike.

Although we generally end up with a pretty good idea of the number of plants we saw, especially when discussing it with each other at the time, there very well could have been more plants in bloom for some species that we didn't notice. Hence these numbers should in general be treated as minimum numbers of plants in bloom along our hiking routes.

No guessing, extrapolation, or interpolation was used; we only estimated the actual number of plants in bloom that we saw. For example, if our attention was diverted elsewhere at the only location of a species in bloom as we hiked by it, we did not count it as being seen in bloom. For example, in 2011, snow-plant was almost surely in bloom on the route we surveyed on 6/27, since some of the same plants were seen in bloom on that route on 6/22 and 7/1. But since somehow we missed seeing it in bloom that day, no numbers were reported for it in the table below.

I.e., the absence of a number in the table below does not necessarily mean no plants of that species were in bloom.

Number of Species and Plants in Bloom On Each Trip

Three plots are given below:

• The first two plots, Figures 1-2, show what was observed on each trip, the total number of species in bloom and the total number of plants in bloom. The total number of plants in bloom for each individual species is capped at a maximum of 99 plants.

• The next plot, Figure 3, gives the cumulative total numbers from all trips so far this season, of all species seen in bloom. These cumulative total numbers include the number of species on a given trip as well as those from all trips previous to that trip.

In Figures 1 and 3, data from just the Devils Slide Trail from 2006, the severe drought year of 2007, and from 2011 are plotted as well for comparison. Since not every trip in 2011 involved the Devils Slide Trail, the curve for 2011 has fewer points than the curve for 2007.

Note that the Devils Slide curves for 2011 follow the curves for 2007 almost exactly, with the main difference being a slight pause in the decline in the number of species in bloom in 2007, which was probably due to more extensive summer rainfall that year in August.

The plots and the table here must be interpreted cautiously, for at least two reasons:

• First, long hikes will find more plants in bloom than short hikes.

• Second, some areas have a higher species diversity than others, and so will have more species blooming at a given time.

List of Species in Bloom On Each Trip

Table 4 gives the number of plants observed to be in bloom for each species on each hike, with a maximum value of 99 plants for each species. This maximum value prevents one species from dominating the total plants in bloom, and makes it much easier on me to keep track of the bloom.

Because the hike locations vary, some species will not be present on every hike, so the lack of an entry for a given hike says nothing about whether that species is blooming elsewhere. For example, the 2011 hikes on 8/2, 8/7 and 8/12 were all in the Fuller Ridge Area, whereas the 7/1, 7/6, 7/11, 7/26, and 8/16 hikes were all in the Devils Slide / Skunk Cabbage Meadow / Reeds Meadow area. A glance at the first ten species in the table below will show some of the differences in those areas.

The Checklist is sorted first by category, with dicots before monocots, and then by family and scientific name. The Family and Scientific Name are from the 1993 First Edition Jepson Manual. An asterisk before the Common Name indicates a non-native taxon.

See Plant Family Abbreviations to obtain the full family name from the abbreviations used in the table below.

Of course, species that bloom later in the year, and species that do not have flowers (ferns, etc.) are not present in this list, so it is not the equivalent of a plant checklist for the higher elevations of San Jacinto Mountain.
