The Botany Society Celebrates Tenth Birthday

Last February, we presented the first in a series of essays looking back and celebrating 10 years of history and accomplishments of the ABDSP Botany Society. That article reported on the goals of the Society and the activities put in place in the first year to achieve them. This second retrospective will focus on two parts of our mission: education through field work and building a scientifically useful herbarium.

There is no better way to learn about plants than to see them in their native habitat, watching them germinate, grow, flower and fruit. Throughout our 10-year history, a high priority for new and seasoned Botany Society members is to do just that. San Diego County contains one of the most diverse flora on the continent, and ABDSP encompasses many plant habitats ranging from the desert floor to the montane, offering rich opportunities to learn.aInformation documents our region's unique natural history and biodiversity, and provides valuable scientific data showing how it is evolving. These trained volunteers routinely survey one or more sectors within the Park (3 x 3 mile squares) and collect plants not only for the NAT herbarium but also for our CDD herbarium. The goal is to collect a representative of each plant that exists in that sector. Many hundreds of plant specimens have been collected; one is sent to the NAT for identification and another is entered into the CDD herbarium. Even though the Plant Atlas Project is coming to an end, many Botany Society members still monitor their sectors. Most notable of them is Mary Jo Churchwell, who logs in many hundreds of hours each year monitoring several sectors.

The Botany Certification Course held every year heavily relies on field trips for educating new Botany Society members. Our theme might well be summarized by the question: What do you see? What else do you see?

Next time we will focus on the herbarium.

The Latest from Pam's Amble

On Friday, December 14th, Pam's Amble explored the wash leading to Truckhaven Rocks. Amblers were richly rewarded!

Right by the road we were greeted by glowing pink desert sand verbena (Abronia villosa). Then, not only were the usual suspects--lavender (Hyptis emoryi), creosote (Larrea tridentata), and burro bush (Ambrosia dumosa)--in bloom, but indigo bushes vied to paint the wash, well, more indigo, and a rush milkweed (Asclepias subulata) sported cream-colored blossoms.

On a smaller scale, we also saw blooming wishbone bushes (Mirabilis bigelovii), brown-eyed evening primroses (Chylismia claviformis), and even one each of an eye-popping yellow poppy (probably Eschscholzia californica, given the size of the unfurling bud) and more demure ground cherry (Physalis crassifolia).

Also exciting were the vast number of healthy lupine seedlings--the wash should be awash with blue-purple in the not too distant future.

Happy botanizing, Pam

October Showers Bring December Flowers

In mid-October monsoonal rain fell in two distinct locations in the Anza-Borrego Desert. One area was the Borrego Badlands. The other was along S-2 between Whale Peak and the Mountain Palm Spring area. Both areas received about 1. 5 inches in one day, and both now have lots of germination of annuals and even some flowering. Botany Society members have recently hiked both of these areas to see what's coming up. 

In the badlands the ocotillo (Fouquieria splendors) leafed out extravagantly. Many desert lilies (Hesperocallis undulata) are also showing their leaves. A couple of them were even in bloom, which is remarkable for December. A few hairy desert-sunflowers (Gerea canescens) have opened up. Most remarkable was the number of barrel cactus (Ferocactus cylindraceus) with buds and flowers. Emerging annuals include Arizona lupine (Lupinus arizonicus), Thomas' buckwheat (Eriogonum thomasii), and California caltrop (Kallstroemia californica). The caltrop is a monsoonal annual that only comes up in response to summer or early fall rainstorms. Dune evening primrose (Oenothera deltoides) is just starting to bloom. Perhaps the most uncommon plant we saw in bloom was Long-beak streptanthella (Streptanthella longirostris), a dune inhabitant. 

The south end of the park was equally florific. The most frequently seen plant was Brown-eyed primrose (Chylismia claviformis peirsonii) which is blooming by the thousands in June Wash. Devil's Claw (Proboscidea althaeifolia), another monsoonal annual, was abundant in Canyon 41 and Canebrake Canyon. It had both flowers and fruit in early December. Indigo Bushes (Psorothamnus schottiiwere covered with deep blue flowers especially in the late afternoon. A few Orcutt's woody asters (Xylorhiza orcuttii) were seen in June Wash, but not yet in flower. The most unusual and surprising find in this area was a hybrid brittle bush, a cross between Encelia farinosa and Encelia frutescens. At at distance the plant appears to be a normal brittle bush, but closer examination reveals that the leaves and flowers are somewhere between the two parents. Three of these hybrid plants were observed in June Wash.

The bottom line is that there are plenty of plants to see if one goes to the places where rain has fallen. However, the condition of plants changes rapidly with the weather, so don't delay. Get out there and see what's blooming.

Jim Dice to Speak on Botanical Research in Borrego

Jim Dice, Reserve Manager

Jim Dice, Reserve Manager

Jim Dice, Reserve Manager, UCI Steele/Burnand Anza-Borrego Desert Research Center, will be the January speaker as part of the Botany Society’s Public Lecture Series. He will discuss History of Botanical Research in Borrego on Monday, January 14, 2019.

Jim Dice has been Reserve Manager since the Steele/Burnand Anza-Borrego Desert Research Center opened in 2012.

Two Top Speakers Highlight Botany Society's First Monthly Lecture

The Anza Borrego Desert Botany Society is fortunate to have 2 gifted speakers for our monthly lecture series this coming Monday (Dec 10) at 10 a.m.

Our first speaker is Kate Harper, known familiarly as Botany Woman. Kate has been a botanist in the Borrego area for years and is a principal contributor of Tom Chester’s excellent Web site, Plant Species of the Borrego Desert.

Kate will focus on desert adaptations. Hear her speak to learn which plant is the “King of Desert Plant Adaptations.”

Following Kate’s talk will be Dr. Chris McDonald, Natural Resource Advisor for southeastern California. Chris will discuss plants that jeopardize desert native plants. McDonald is an expert in invasive plants and will demonstrate how to recognize aggressive, invasive plants in the Borrego Desert and discuss what can be done to control them.

Dr Chris McDonald is the Inland and Desert Natural Resources Advisor for the University of California Cooperative Extension. His expertise is in managing plants in wildlands with an emphasis on managing difficult weeds.
