Thursday January 12th - “The Nature of Madera Canyon” presented
by Doug Moore. Doug Moore is a passionate and knowledgeable
naturalist of the Santa Rita Mountains. He is a docent and Education
Director of the non-profit volunteer organization Friends of Madera
Canyon. He is also the author of The
Nature of Madera Canyon, and
will present a natural history overview of Madera Canyon and surrounding
Santa Rita Mountains including geology/formation, climate, Sky Island geography,
life zones and associated plant communities
highlighting interesting habitat, plants and animals.
Thursday February 9th – “The
Ironwood Event of September 9th, 2011” presented by Bill
Peachey. A five-day incursion of tropical moisture in September of 2011
achieved an indelible mark in the Tucson areas history of weather events
that included a record “fudging” downpour at T.I.A., a giant “haboob”, AND a storm-cell that spawned a series of
“microbursts” that left a path of destruction of property and Sonoran
Desert vegetation across Pinal & Pima Cos. in SE Arizona. Bill
Peachey will present a program that describes and discusses the implications
of the “Ironwood Event” of 09 September 2011: one of the
microbursts that damaged or felled thousands of saguaros within a 5.7 sq.
mi. area of eastern Ironwood Forest National Monument.
Thursday March 9th, “Creosote bush and pollinator
interactions among individuals differing in chromosome complement”, presented
by Rob Laport, PhD. Much of the floral diversity in flowering plants is
the result of evolutionary pressures to ensure pollination and or
reproduction. Physical alterations to the appearance of plants and their
flowers can arise as a consequence of genome duplication, or via the
acquisition of multiple copies of genes responsible for flower color,
size, shape, and rewards. Until recently it has been unclear how changes
in the number of gene copies via genome duplication or other processes may
influence pollinator visitation. Rob Laport a
Postdoctoral Research at the University of Colorado-Boulder will talk
about his research on how genome duplication has structured not only the
biogeographic distributions and overall appearance of the southwestern
desert creosote bush (Larrea tridentata), but also how in turn such
differences may ultimately influence native and honeybee pollination in
this important and characteristic desert shrub.

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.
The Ragged Top Diversity
Wash with Ries Lindley, Saturday 19 March
This is an easy walk up a pristine desert
wash full of Spring wildflowers and native grasses. If you have
a high clearance vehicle, please bring it so we can carpool.

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.

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

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.
