Flora of the Dragoon Mountains by Doug Ripley

In special springs, when the winter rains have been plentiful, nature throws an exuberant party with wildflowers as the guests of honor. The unpredictability of these special shows makes them all the more precious. This spring may bring some surprises as the rains came late but have been abundant. We’ll look at various germination strategies of the ephemerals and how flowers and their pollinato...

Jared and Katy celebrate and promote ecological native plant landscaping through their business, Spadefoot Nursery. Their program will be a discussion about a different sort of horticulture one that doesn't center the plants and how they look but rather views plants as part of a larger ecology. Jared and Katy own Spadefoot Nursery in Tucson which is entering its 6th year of operation. Both of t...

All organism reproduce - and among organisms, plants reproduce in the most diverse ways. Reproduction takes place via flowers that range from the size of a pinhead to the size of a teenager. Some plants make flowers but then fertilize only themselves. Most, however, require pollen to be moved between flowers, a feat accomplished by wind, water, and animals ranging from insects to fish to birds ...

Summertime in the South or on the East Coast is synonymous with fireflies. As darkness falls, generations of children have collected them in jars and turned them into summertime lanterns. But fireflies in Arizona? Believe it or not - yes! Dr. Joe Cicero will discuss the three kinds of fireflies that occur in our state, the life cycles of these insects, how they communicate by way of luminescenc...

Presented by: Jim Verrier The large number of subtropical plants reaching their northern range in the U.S. sky islands contribute to the unique botanical flavor of this biodiverse region. This talk will explore the extent of subtropical plant distribution in the Arizona-New Mexico sky islands, drivers of subtropical plant occurrence, regional patterns of subtropical species turnover, and sky is...

Speakers: Gita Bodner and Collin Gillespie Mesquites are some of the most flexible and adaptable plants on the planet, with the same species capable of growing as tall forest trees, or knee-high thorny shrubs. This flexibility has led to confusion among researchers and conflict among land managers. Forests of large spreading mesquite trees once sheltered the floodplain terraces of rivers across...

AZNPS Conservation Committee chair John Scheuring speaks to us about the successful AZNPS restoration project in the Waterman Mountains. John describes the process of removing a massive buffelgrass patch and installing water harvesting structures to improve native plant recruitment.

This program is a visual journey through the life and work of Sara Plummer Lemmon, for whom our beloved Mount Lemmon is named.

Here is an opportunity to get behind the scenes and experience photographs, art work and other details that are not included in this wonderful book. Some of the artwork w...

Anyone living in SE Arizona in the second half of 2021 couldn’t help but notice the unprecedented abundance of butterflies that appeared with the strong monsoon rains and the burst of plant growth. These colorful insects, whose lives are inextricably linked to our native plants, will be the topic of this presentation. Fred will present a brief primer on butterfly biology: life cycle, host vs. n...

Will the Sonoran Desert have a good wildflower season? There’s no way to know if it will, but we can all see some wildflowers at this presentation! Take a visual and verbal walk through the winter/spring annual plants with Sue as your guide. See some all-time favorites and some more unusual species. Be prepared to share your favorite spots to see wildflower displays or unusual plants. Sue Rutma...

The lives of birds and many other organisms are intricately intertwined with native plants for food and shelter. We’ll explore some of the specific deleterious impacts that non-native plants have on local birds-from wholesale landscape conversions as a result of inappropriate fires, to energetic stresses that come from foraging on too-small seeds and too-few insects, to the food-deserts of typi...

The quintessential image of “cactus” and of “desert” in the minds of most people is Carnegiea gigantea, our beloved saguaro. How has this one relatively restricted plant species come to bear the burden of so many expectations and assumptions? In this talk, Larry Bird will draw from his recent book, In the Arms of Saguaros: Iconography of the Giant Cactus, to discuss the history of the saguaro c...

Arizona is home to an astounding diversity of bees; with well over 1200 species, it is arguably the most bee-diverse region on the globe. Arizona’s native plants depend on this bee diversity for pollination. Many of Arizona’s bees are specialist pollinators, and some of them are rare or range-limited. Unfortunately, native bees are in decline. Fortunately, the causes of this decline are within ...
