Plant Checklist For Our Higher-Elevation Surveys of San Jacinto Mountain

As of 10 October 2018, we have digitized 12,859 species GPS points from our surveys of the higher elevation of San Jacinto Mountain. We've digitized all surveys down to 9000 feet, so the data are complete only from 9000 to 10,800 feet. However, it is getting pretty complete down to 5000 feet, so we decided it was time to take a look at the data as a whole, and put the list of species online so we could easily check to see what species we have seen that might be missing from the list.

Fig. 1 shows the number of GPS points for each species as a function of the maximum observed elevation for each species.

Fig. 1. The number of GPS points for each species as a function of the maximum observed elevation for each species. The species with over 600 points is Pinus jeffreyi, which is the result of a number of specific surveys for it and P. ponderosa (which has 170 species GPS points at a maximum elevation of 6950 feet. The species with 355 points is Abies concolor, our most widespread and abundant tree at the higher elevations of San Jacinto Mountain. The number of species GPS points is higher for species with a maximum elevation above 8000 feet due to the larger number of spot surveys done at those elevations.

There are 649 taxa in our species GPS point database, with elevations from 10,800 feet at the top of San Jacinto Peak to elevations of ~4,500 feet in the Idyllwild and Garner Valley areas.

One measure of the incompleteness of the species GPS point database is to see how many species recorded in our master database for SnJt did not yet have any digitized GPS points. There are 141 taxa in our master database that do not yet have any digitized GPS points. Since our master database is incomplete as well, this is a minimum number of species missing from the GPS point database. The total number of taxa from our surveys is thus at least 790.

Fig. 2 shows the cumulative number of species as one goes from the top of San Jacinto Peak at 10,800 feet to lower elevation, both as observed in the GPS point database and with an estimated curve that includes the 141 taxa that do not yet have digitized GPS points.

Fig. 2. Cumulative number of species from the highest elevation to lower elevations. The solid blue line shows the actual cumulative numbers for species in the GPS point database. The solid red line is a guesstimate that includes the 141 taxa whose GPS points have not yet been digitized. There are additional species from our surveys not present in either database yet.

It is also of interest to compare the minimum observed elevation for each taxon with its maximum observed elevation. The maximum observed elevation at San Jacinto Mountain is of course San Jacinto Peak. The minimum observed elevation is the lower limit of our surveys, which is something like 4000 to 4500 feet. Note that many of those species has an actual lower elevation limit at San Jacinto Mountain well below 4000 feet elevation.

Fig. 3 plots the maximum observed elevation for each taxon vs. its minimum observed elevation.

Fig. 3. The maximum observed elevation for each taxon vs. its minimum observed elevation. Note that there are many species whose lowest elevation is 4000 to 6000 feet in the database, and they drop out almost uniformly in the elevation range of 5000 to 10,000 feet. In contrast, there are few species with a lowest elevation of 6000 to 7800 feet, and a highest elevation below 9000 feet, with considerably more with a highest elevation above 9000 feet. There are a fair number of species with a lowest elevation of 7800 to 9000 feet which extend up to 9000 to 10,000 feet. See also the same plot with labels on it for three of those four categories.

Table 1 gives the list of species in either or both of our GPS point database and our Master Survey List, in alphabetical order by Species Name.
