Tucson Chapter

President:  Anthony Baniaga, email

Vice President: Andrew Cordery, email

Treasurer: Jackie Taylor, email

Secretary: Arlette Corderyemail

Chapter meetings and evening programs are held on the 2nd Thursday of each month from September through May, beginning at 7:00 pm. Our monthly meetings are held at the City of Tucson Ward 6 Office, 3202 East 1st Street, south of Speedway Boulevard and east of Country Club Road.

Look for the AZNPS sign board. We often have raffles for native plants, posters, or related books at each meeting, so be prepared!

UPCOMING Chapter Meeting Presentations

Thursday April 13th, “Plant disease in native ecosystems: what to worry or not worry about” presented by University of Arizona Professor Dr. Barry Pryor. Based on years of collections and research on plant pathogens, Professor Pryor will highlight the principles of plant pathogenesis in native ecosystems. He will also highlight historic catastrophic case studies relevant to our native flora such as sudden oak death as well as relate how plant diseases are a natural part of ecosystem cycling.

 

Thursday May 11th, “Globemallows: the Species Problem”, presented by Ries Lindley. Our ideas about science evolve slowly, even though there may be precipitating events for change. Before the publication of Charles Darwin's Origin of Species in 1859, species were immutable, afterward, well, things got mutable. Globemallows are a good group of plants to illustrate the problems of species. These southwestern plants offer us insights into our thinking and their history. The globemallows are deceptively complicated, and they could change the our ideas about the question, "What is a species?"

REPORTS OF FIELD TRIPS

Saturday November 12th, 2016. Desert Mistletoe on Desert Legume Woodies with Kelsey Yule.

After her informative November 8th presentation, Kelsey Yule (PhD Candidate in the Department of Ecology and Evolutionary Biology at the University of Arizona) directed a field trip for Tucson chapter members to the Ironwood Picnic Area at Tucson Mountain Park. At that site, she was able to show the group desert mistletoe growing on five different legume hosts: desert ironwood, velvet mesquite, catclaw acacia, whitethorn acacia, and foothills palo verde. Attendees enjoyed seeing the differences between mistletoes infecting different host species, learning to sex this dioecious plant, and observing how mistletoes are transmitted between hosts.

 

Saturday October 29th, 2016. Salvaging, propagating, and landscaping Native Desert Plants with Jesse Byrd.

Following up on an excellent October 12th presentation, Jesse Byrd (Pima County Native Plants Nursery Manager) led a group of Tucson chapter members and Master Gardeners through the diversity of native plants and operations at the nursery. Very cool to see the salvaged and flourishing cholla, opuntia, and saguaro cacti as well as the extensive queen of the night collections. Later we visited two recently landscaped sites on the westside of Tucson; the Pima County Housing Extension Office, and Las Iglesias Restoration Site along the Santa Cruz.

 

Saturday September 24th, 2016. Common Sense Water Harvesting Tour.

Our annual event that highlights common sense passive water harvesting in Oro Valley and Oracle. An eccentric mix of Tucson chapter members and Master Gardeners visited several front yard and roadside water capture berms in action throughout Oro Valley and Oracle. These included Chuck LeFevre’s landscaped hillside at the Oracle Community Center as well as several private home landscapes where Chuck has made his lasting mark. We finished our tour with a sumptuous lunch at the Patio Cafe in Oracle.

Saturday, March 29, 2014: Selaginella and Ferns of the Catalinas

Fifteen people traveled up the Catalina Highway to learn more about the local ferns and Selaginellaspecies. Dr. Michael Barker discussed the evolution and genetics of ferns and Selaginella at Molina Basin Overlook along Catalina Highway. Anthony Baniaga pointed out three different Selaginella species and ten fern species at different locations along the highway. We explored canyons where there were pools and running water. For a photo report, click here to see Sue Carnahan's photo collection which includes photos of the flowering plants as well.

August 22-24, 2013: Chiricahua Workshop-Southwestern Research Station

This year’s August field trip to the Chiricahua Mountains yielded over 200 species to 21 participants, who hailed from four different chapters. The bloom was richest in the high altitudes, but field trip diversity included plants from the high Chihuahuan desert to the montane forest at the top of the mountain range. Explorers spent an entire morning just ferreting out plants of the Paradise cemetery. Generous assistance was provided by area residents P.D. Hulce, leading the trip to his private paradise in the mouth of Horseshoe Canyon, and by Dave Jasper who lead the trip on the gorgeous upper trail at Rustler’s Park. Elaine Moisan led a great trip to the Paradise Cemetery on that sunny and wonderful last day. The Southwestern Research Station provided great accommodations, delicious food, a lovely picnic area for wine sipping and a lab for the plant ID workshop.

March 1-3, 2014, Wildflower Foray to Tinajas Altas

 

The Tinaja Altas (High Tanks) is located in southwestern Arizona 65 km ESE of Yuma, and only 6 km N of the Sonora border. The Tinajas Altas Mountains are the southeastern extension of the Gila Mountains.Tinajas Altas was always a crucial water source for travelers along the Camino del Diablo, especially during the gold rush of 1849. Many unfortunate travelers were buried in stone covered graves on the nearby Mesa de los Muertos.

In the early 1980s, Tom Van Devender and paleoecologists from the University of Arizona’s Desert Laboratory on Tumamoc Hill visited Tinajas Altas to collect ancient packrat middens. Plant remains from 21 radiocarbon dated midden assemblages provided a record of the vegetation in this area for the last 43,200 years! During the last glacial period (the Wisconsin), a pinyon-juniper woodland with singleleaf pinyon(Pinus monophylla), California juniper (Juniperus californica), and Joshua tree (Yucca brevifolia) was present. The lowest elevation record for the pinyon in the Pleistocene was 430 m in a Tinajas Altas sample dated at 11,040 B.P. Sonoran desertscrub became dominate about 8,900 years ago, although the modern dominants foothills paloverde (Parkinsonia microphylla) and ironwood (Olneya tesota) did not return until about 4,000 years ago.

On March 1-3, 2014 Tom and Ana Lilia Reina-G. led an Arizona Native Plant Society group of 25 people from Tucson, Phoenix, Flagstaff, and Y Junction to Tinajas Altas. This part of Arizona had very good winter rains, and the landscape was in flower. The yellow flowers of brittlebush (Encelia farinosa) and red flowers of chuparrosa (Justicia californica) colored the landscape. Nearly 150 species of plants were seen atTinajas AltasTinajas Altas Pass, desert flats east of Raven Butte along the road to Wellton, the Mohawk Dunes, etc. The birders on the group were able to record 37 species of birds. Some lucky participants were treated to a pair bighorns –mother and lamb on a high cliff at sunset. The observations and images will go into the MABA database, available for use by land managers in the Barry M. Goldwater Air Force Range.

Tinajas Altas Snail

Tinajas Altas was a crucial water source along the Camino del Diablo for travelers during the gold rush. In 1849, a man named Frick, presumably in route to California, collected some land snails at Tinajas Altas. The same year Wesley Newcomb, New York physician and amateur malacologist, traveled to San Francisco. Sixteen years later, he described the Tinajas Altas snails as Helix rowelli, probably the first terrestrial land snail known from Arizona. The snail was later called Sonorella rowelli (1904) and today isEremarionta rowellithe eastern desertsnail.

Sonorella and Eremariodonta are air-breathing land snails that are well known for having species with small geographic ranges. The San Xavier Talussnail (S. eremita) is only known from a deep, limestone rockslide in Pima County, Arizona, and is protected by a Conservation Agreement between El Paso Natural Gas Company, Arizona Electric Power Cooperative, Inc., Arizona Game and Fish Commission, and the U.S. Fish and Wildlife Service. The Saracachi talussnail (S. aguafriensis) is only known from Arroyo Santo Domingo near Rancho Agua Fria and the Saracachi Ciénega southeast of Magdalena, Sonora.

Tinajas Altas is in the Barry M. Goldwater Air Force Range, administered by the U.S. Marine Corp. The eastern desertsnail was first found 165 years ago, and current management will insure its survival.
