Introduction

The plant trail guide has been updated with all field work through 12 September 2014, but some sections in this webpage have not been updated since 2003.

Highlights of This Trail

Botanical highlights of this trail include:

Number of Unique Taxa On This Trail

The following histogram gives the number of trails and floras from our surveys, that are in our database (many of our surveys are not yet in our database) that contain each taxon on this trail. We had 321 of our trails and floras in our database when this histogram was made on 15 September 2014. A number of "1" means the taxon has only been found on this trail among our trails or floras in our database.

The table above does not contain the two taxa vouchered on this trail that we've never recorded in our database.

The taxa seen only on this trail, or on just two other trails / areas, as well as two taxa which are vouchered from this trail but which we have never recorded in our database, are:

3Sequoiadendron giganteum*giant sequoia

Sequoiadendron giganteum is non-native here, and has been planted in the parking lot area.

Although our database is incomplete, and does not contain all our surveys, the taxa in the above table are indeed quite uncommon in our surveys.

Fieldwork Dates and Summary of List Changes With Time

This section has not been updated, and is unchanged from the 2003 version.

The following table gives the dates the trail was walked and taxa recorded. After each visit, the table gives the total number of taxa on the list and the breakdown of the taxa without positive identification. See Explanation of Plant Trail Guides to understand the symbols below.

9/25/20032636130

The 8/30/02 fieldwork was only to mile 2.32.

The Plant Guide

This guide now mostly uses the scientific names from the Jepson Manual Second Edition, 2012, with these changes.

The mileage is from the Topo! route drawn from several GPS tracks of the trail, and might be underestimated a bit due to the large number of tight switchbacks.

There used to be a number of signs placed at switchbacks that numbered the switchbacks and gave their elevation, as well as the mileage to each one in hundredths of a mile, but all those signs were gone as of 2014. The guide retains the info from those signs as of 2003. The mileages on the signs in the upper part of the trail were roughly 0.10 miles higher than the numbers in the guide.

For this guide, we've relaxed our usual tight criterion for whether a plant is "on trail" or not. Only plants not easily reached from the trail now qualify for being put in parentheses as being "off trail".

Comments On Specific Species

Ceanothus cordulatus and Abies concolor. The first occurrences of these taxa were dead in 2003 and 2014, respectively. The guide gives the first live plants in 2013.

~Allium monticola. Only dead inflorescences were observed in 2003, but the bract length, bract shape, tepal length, and pedicel lengths are only consistent with this id. However, we still qualify this id as only being 95% since we have not observed a bloom yet.
The second occurrence of dead onion inflorescences was at 0.07 miles from the top. Although we did not measure those dead inflorescences, only Allium monticola is found above 9000 feet, according to the floras, and hence again this is the likely id.
