Introduction

The Big Spring tributary of Upper Tubb Canyon must be one of the best-kept secrets of Anza-Borrego Desert State Park. We, and zillions of other people, have driven S22 starting down the Montezuma Grade without having any idea that the very dry landscape around S22 harbors not only a "Big Spring", but a creek with over a half-mile of year-round flowing water! We were simply dumbfounded to discover this the first time we looked at a Google Earth view of the area, and saw the extensive stretch of vegetation along it.

However, the water is normally guarded well by dense vegetation, steep slopes, and waterfalls. Schad (2010, p. 318) comments in describing a hike to Big Spring that:

the water gushes through tall thickets of seepwillow and thorny tangles of catclaw and mesquite - making it hard to reach the water with one's hide intact.

However, a lightning-caused fire burned the entire area in August 2012, which created a window of opportunity to explore the spring and the creek below it before the vegetation grows back and once again make access difficult. However, be warned that there are a number of waterfalls along the creek below Big Spring, so the trip below Big Spring is not for the faint of heart.

Checklist for Upper Tubb Canyon / Big Spring

This checklist is compiled from 2.5 days of fieldwork:

This preliminary checklist is probably still incomplete for some winter / spring annuals and perennials, and some of the determinations may be incorrect that were made from resprouting plants or young annuals not yet in bloom. Species that were not definitively determined are identified in the checklist below.

See:

The family name is abbreviated to the first five characters in order to save space in the table rows.

An asterisk before the Common Name indicates a non-native taxon.

The column labeled #Pls gives a minimum estimate of the number of plants from the field surveys, up to a maximum of 99 plants, for species seen in the field surveys for which abundances were noted. A ~ before the number indicates that the species or subspecies determination is not certain, but instead was just our best guess from the observed plants.

Because no vouchers for this area were present in the Consortium of California Herbaria on 18 January 2013, no voucher column appears below. Mary Jo Churchwell is currently documenting this area, so vouchers will be present online in the future.
