Thursday April 12th, “Hydrology and
vegetation of the fresh water pozos of the Gran
by Ben Wilder.
The Gran Desierto region
of the Sonoran Desert is the largest extent of sand dunes in North
America. An array of freshwater springs (or pozos) miraculously punctuate the salt flats
where the dunes meet the sea. Unresolved in origin, and essential to
countless species, their waters rise up inextricably out of the dunes.
This transdisciplinary collaboration between a
botanist, hydrologist, and artist seeks to document the origin of the pozo’s water, determine how long it has resided below
the dunes, and show how the pozo’s and the
riparian vegetation they support has changed through time. Likewise, the
project, a part of the Next Generation Sonoran Desert Researchers 6&6
art-science collaboration (nextgensd6and6.com) will document this
wide range of dependent themes as part of the 6&6 art show at the
UAMA opening in January 2019. From the traditional salt pilgrimage of the
Tohono O’odham people, to nesting raptors, generations of cottonwood
trees, and the future of water in the binational
Sonoran Desert desert;
these springs are central to the larger story of how humanity interacts
with water in the arid west.

Desert Plants: Seasonal Flowering Schedules
based on 20 years of data from 1966-1985
by William G. McGinnies
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
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.

Late Summer in the Chiricahua Mountains,
September 5, 6, and 7, 2015
The Cochise and Tucson Chapters of the Arizona
Native Plant Society held their fourth annual weekend at the Southwestern
Research Station in the Chiricahua Mountains
of southeastern Cochise County. 25 members enjoyed good food, good company
and perfect weather in these richly diverse mountains on one the
northern-most islands in the Madrean Archipelago
that encompasses parts of Arizona, New Mexico, Sonora, and Chihuahua.

Saturday, August 16,
2014: AZNPS Wildflower Walk in Madera Canyon
For the third year in a row, the eminent
naturalist Doug Moore led 14 members of AZNPS to the Carrie Nation Mine in
the Santa Ritas. Click here for photos
now posted on Facebook of the flowers seen on the hike. Midway up the
trail, the group saw the biggest spread of red cinquefoils they had seen in
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.
Anthony explains how to ID fern species. He measures the
fronds to determine species.

participants study ferns.
August 22-24, 2013: Chiricahua Workshop-Southwestern
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 Altas, Tinajas 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 rowelli, the 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.
