Climate change – a curious nature

The Cowpen Daisy ….. One of the Happiest Sunflowers Ever!

Part 1 ….. Can There Be Too Many Sunflowers?

August 5, 2025

It was the Fall of 2024. A small cluster of Cowpen Daisies (Verbesina encelioides) flourishing on the severely disturbed ground surrounding our new home was going to seed. Waiting several weeks until the migratory birds ate their fill, I spent an hour or so collecting as many remaining dried seeds (cypselas) as possible, stuffing full two quart-sized ziplock bags. About 1/3 of the seeds I scattered around the house where they would overwinter on the ground. The rest were poured into large pill vials that were labeled with species name, location, and date, then placed in the refrigerator to simulate cold storage until Spring.

It was late April 2025. The chances of heavy frost seemed a distant memory. My fingers crossed, I chose a sunny 42 degree morning to liberate those refrigerated seeds from 6 months of cold storage, and scattered them in disturbed areas not seeded last Fall. Then I waited like an expectant parent, watching for signs of germination, worrying that runoff from late season snows might wash away my scattered seeds, expecting that flocks of migratory birds would gobble them all up, and hoping for gentle rain showers to swell those thousands of seed coats to aid those tiny embryos in growing their first roots (radicles) and first leaves (cotyledons).

Then early June 2025. Success! Cotyledons were literally popping up everywhere, which meant the radicles were already expanding into the soil. They were especially crowded where I’d scattered all the cold storage seeds, and germination was obvious where seeds had been scattered the Fall of 2024. By early July, those Cowpen daisies were crowding out many of the other native species I’d also seeded in the same areas.

And now it’s early August 2025, and what a dazzling show! Even though the sunflower yellow flowers of Cowpen Daisy are small (2” wide), there are up to 75 long-stemmed flowers on each plant that can grow from 4-5’ tall! They are so dense, the backyard fence is hardly visible, our walking paths are totally draped with 4” long leaves, and if there’s a rattlesnake lurking around under our massive Cowpen Daisy canopy, we’d probably (hopefully) hear him well before he slithered into view!

Goals and Lessons Learned

I’ve learned a lot by parenting these Daisies; from the best time to scatter seed (in the late Spring following cold storage) and where (not so close to other desirable natives or pathways), to managing the mass of growth (by organizing through selective removal). Our initial goal of seeding and growing native plant species was to attract and help feed wildlife (pollinators, reptiles, rodents, birds and mammals), and we are optimistic that achieving this goal long-term seems realistic with the success we’ve had to date. However, because so many of our native plants are losing the battle against habitat loss caused by invasive species encroachment and takeover, land development, and climate change, we will continue to explore ideas to expand our initial goal to address the habitat situation. As we gain insight about the best native plants to grow to help restore our disturbed soils, we will learn and share with our neighbors those species that: are drought tolerant; aid in building soils; are effective at invasive weed suppression; provide wildlife benefits; and increase plant diversity.

Happy – Happy – Happy! Will I be collecting Cowpen Daisy seed again this Fall? You bet! Having all that sunshine yellow around our home is thrilling. Every morning all those thousands of sunflower faces looking East towards a new day are about the happiest sight ever! And having such wild, uninhibited growth of a native annual out our back door has been ideal for observing the pollinators that benefit from the abundant nectar and pollen, enjoying the aerial acrobatics of several phoebe families that have been feasting on those pollinators, and promises to be a perfect spot for bird watching this Fall when all those cypselas ripen into high protein food.

Can’t wait!

Do you ‘know’ a special native plant? How about a native butterfly garden? Are you a bird watcher? Maybe you enjoy the occasional deer, coyote, or bobcat wander through your yard? Please share your favorite wildlife encounter!

As always, thanks for stopping by!

High on the Views: Camping Above the Rio Grande

June 6, 2025

Such an awesome-inspiring place to spend a Spring week in New Mexico!

Three of the five big boys! Rocky Mountain Big Horn Sheep.

Rio Grande del Norte National Monument …..

comprises a breathtaking 245,000 acre area of the northern Rio Grande rift valley in north central New Mexico. Established as a Bureau of Land Management (BLM) national monument in 2013, the rugged wide-open plains average 7,000 feet in elevation before dropping into steep narrow canyons carved into the landscape by rivers that have been flowing for millennia.

The confluence of two of these rivers, the Rio Grande and the Red River, occurs in the northern Wild Rivers area of the Monument. It’s at this confluence where the gorge is its deepest at 800 feet, and its widest from rim to rim measuring 3/4 mile. It’s an impressive view from the la Junta (“the Meeting”) Overlook. All of the views from anywhere along the rim are impressive.

We backed our RV (‘Felix’) into what must’ve been the best designated camping site ever ….. #9 on the southern loop in Big Arsenic Springs Campground. After setting up, we discovered that Felix rested only a few steps west was the rim and the long plunge down to the Rio Grande! But immediately south of us, the rim formed a small peninsula where nearly every afternoon I could be found sketching the plants growing from the basalt cliffs, or the swifts and turkey vultures soaring along the cliffs and over the river aided by the canyon’s updrafts. This skinny little peninsula quickly became my favorite sit spot; then late one morning it became priceless …….

Can you spot our RV? We were precariously perched above the Rio Grande, right on the rim of the gorge!

I could hear them approaching, like a swarm of bees. In a matter of seconds I was witnessing a cacophonous chorus of 100’s of pinyon jays. These noisy birds quickly moved in and onward while descending, like they were famished, on this year’s piñon pine cone-laden trees in large erratic groups, all the while screaming, “Hurry, Hurry, Hurry, Hurry!” Where exactly they came from or where they went remains a mystery. All I know was the spectacle must’ve lasted a good 10 minutes or more, as I watched wave after wave of these birds pass by. I still get goosebumps (jaybumps?) recalling those exciting moments.

We had planned to spend only one day camping in the Monument, but every morning we decided to stay at least another and then another day. We hiked every rim and interior trail (sometimes more than once), spent hours at all of the Overlooks getting ‘High on the Views,” were thrilled with our chance encounters of five (5) Rocky Mountain Big Horn Sheep rams (twice in one day), and marveled at how the forces of nature* collaborated to carve the narrow and steep 800 foot deep gorge within the Monument.

But alas, it became time to pack up our home away from home. Even tho a string of completely clear days allowed sun to shine on our solar panels from sunup to sundown, keeping Felix’s battery purring happily our entire stay, it did nothing to recharge our potable water tank. So the morning we found the water indicator light teetering on ‘Empty,’ was the day we headed for home (after enjoying a farewell hike, of course) with my nature journal full of sketches and memories for a lifetime!

Do you have an especially special place where you can spend time in nature? Please share your discovery and what makes it so awesome!

As always, thanks for stopping by!

*Geology 101

From the overlooks throughout the Monument, we could see stacks and stacks of basalt and ash lining the narrow canyon walls of the Rio Grande Gorge. It’s hard to imagine the volume of material deposited during two very active periods of volcanic activity that occurred 5 and 3 million years ago. Soon after these events, water moving through the major drainage in the area (today’s Red River) began eroding pathways into these deposits as it flowed downstream into the 10-16 million year old rift valley. Geologists refer to the ancient Red River drainage as the ‘original Rio Grande’ because the still-closed San Luis Basin to the north (in south central Colorado) would not overflow for a few million years. Then 400,000 years ago, coinciding with a change in climate resulting in an overabundance of snow and rain, the San Luis Basin filled and spilled. As water does so well, this new and powerful river, today’s Rio Grande, moved ‘downhill’ towards the ‘original Rio Grande’, cutting through everything in its path (including the ancient volcanic deposits). When it converged with the ‘original Rio Grande,’ the erosive force of both rivers became enough to eventually carve out an 800-foot deep gorge in the Rift.

A Quirk of Nature: Fourwing Saltbush

November 25, 2024

In November 2023, I created a journal page of seeds and seed pods, which posted on 12/14/2023, under the title November Littles: Seeds, Pods, Silk, and Wings. On that page was a small drawing of two Fourwing Saltbush seeds, absent any information about this plant species, Atriplex canescens. At that time I remember finding a wealth of articles and research documents about this widespread shrub, but what really stuck in my mind was a very unusual quirk exhibited by this plant. Finally, a year later and WOW! I discovered Fourwing Saltbush has a reproductive superpower …… this species has the ability to change sex!

An Unusual Quirk

My first dive into the literature revealed that within a 7-year period of time, 40% of a Fourwing population switches sexes with 20% of a population changing sex every year. Botanically, this is known as Trioecious, or the 3rd Sexual State.

But clearly a bit of back peddling is needed ……. if Trioecious is the 3rd Sexual State in plants, what about the 1st and 2nd sexual states, huh? Yes, they exist …….. but before explaining them, which requires comparison with the more common sexual state in plants, I must describe this sexual norm.

And now for a little Botany 101 ……..

The Sexual Norm …… Plants with Perfect or Complete Flowers

You are likely familiar with plants like roses, tulips, lilies, garden strawberries, beans, peas and cabbage. If you’ve closely examined their flowers while inhaling their fragrant aromas, you may have noticed their centers have both female and male parts. These are known as plants with Perfect or Complete flowers (aka hermaphroditic or bisexual) defined by each individual flower having a fully functional pistil (the female part) and stamens (the male parts). Worldwide, about 90% of flowering plants have Perfect or Complete flowers.

Monoecious ….. the 1st Sexual State

Here again you are likely familiar with many plant species described as Monoecious (moh-NEE-shuhs). These include corn, all of the plants in the gourd family (i.e. cucumber, squash, watermelon), oak, birch, pine, spruce and dogwood. Monoecious, which means “one house” in Greek, describes plants having separate female and male flowers in different places on the same plant, often blooming at different times. Visualize corn growing in a field; the tassels are the male (staminate) flowers, and the corn kernels you eat are the female (pistillate) flowers. Around 10% of all flowering plant species worldwide are Monoecious.

Not to confuse the matter, but sometimes botanical experts refer to Monoecious species as Perfect or Complete because they have both male and female flowers on the same plant, even though these flowers are separate and considered sexually Incomplete (aka unisexual) by themselves.

Dioecious ….. the 2nd Sexual State

A plant species with individual plants in a population having only female flowers, and individual plants of the same species in the same population with only male flowers is called Dioecious (dahy-EE-shuhs). This Greek word meaning “two houses,” describes plants such as spinach, asparagus, sumac, currant, box elder, willow, holly, ginkgo, juniper and aspen. Only 5% of all flowering plant species worldwide are Dioecious.

Another confusing matter once again. There are botanical experts that refer to plant species with Perfect or Complete flowers as Dioecious because they require cross-pollination to produce seeds (fruit). Tree fruit species such as apples, pears, cherries and plums are common examples.

Trioecious ….. the 3rd Sexual State

An extremely rare reproductive strategy among flowering plants, Trioecious (aka trimonoecious or “three houses”), is characterized by a species that can have Incomplete (unisexual) male, Incomplete (unisexual) female, and Perfect or Complete (bisexual or hermaphroditic) male/female flowers on separate plants in a population or even all on the same plant! Just over 3% flowering plant species worldwide are Trioecious (trahy-EE-shuhs).

This is where Fourwing Saltbush (Atriplex canescens) enters the story

Primarily a Dioecious species, some Fourwing Saltbush populations have a Monoecious component ranging from entirely male (staminate) or female (pistillate) individuals to those that are Perfect or Complete (hermaphroditic or bisexual). And in this Dioecious–Monoecious–Hermaphroditic gender system, referred to as Trioecy, switching sexes occurs. To reiterate from an earlier paragraph, on average, in a 7-year period, about 40% of a Fourwing Saltbush population switches sexes with 20% changing from male to female or from female to male every year.

Reasons Behind and Benefits of Fourwing’s Sex Change Phenomenon

Fourwing Saltbush has evolved to be one of the most adaptable plant species found throughout central and the western US. It grows from sea level to 8500 feet elevation, and in a multitude habitats within a wide range of plant communities, no matter the successional stage. Fourwing can adapt to all soil textures, soil depths and all but the wettest of soil conditions. The species is able to tolerate hot (+100F) and dry (6” precipitation annually) summers, and bitter cold (-50F) and dry winters.

The ability of the species to adapt to such a wide range of physical and climatic conditions is, in part, due to this sex change phenomenon. Environmental stressors seem to be the major triggers resulting in Fourwing plants switching sexes. Female plants are more likely to change sex than male plants, especially following a drought, an extremely cold winter, or after a heavy fruiting season. Because fourwing is so tasty as range forage, overgrazing can also trigger a sex change, with male plants tending to dominate regularly grazed sites. Male plants that change to female typically flower earlier than plants that remain female season after season. And female plants dominate richer sites than do male plants, becoming larger and producing more seed.

Undoubtably there’s more environmental stressors, such as wildfire and other climate change-induced factors, that may result in Fourwing Saltbush to switch sex. I’ll be curious to learn what they are and how these triggers influence the adaptability and survivability of this robust species. And I’m excited get busy marking this season’s female and male plants that we see nearly every day, and will begin more closely observing these populations for gender changes and possible stressors that may have triggered these switches.

A Retrospective and Thoughts on Prospective Studies

There’s so much to learn about Fourwing Saltbush that it seemed logical to tackle one characteristic at a time. Originally I had planned to discuss both the plant’s reproductive quirk and several of its common galls, but found there would be too much information for one post. While deciphering the complexities of the Fourwing’s sex change abilities, I found it necessary to describe certain key botanical terms in my buildup to the crucial piece of the puzzle ….. the Trioecious reproductive strategy. So this post focused on the first of my two journal pages; my beginning exploration into this plant. The galls illustrated on my second journal page, that could not be easily chopped away from the first page, serve as a preview of a future post about the fascinating Fourwing Saltbush.

And Finally ……….

For a shrub I used to describe as a messy tangle of branches haphazardly cloaked with unremarkable features like dusty little grey-green leaves, nearly invisible flowers, shreddy dull grey trunks and a chaotic canopy, Fourwing Saltbush has captured my imagination, respect, and love as an almost invincible survivor of our changing world!

Hopefully you found this interesting and informative. Bet you never look at flowering plants in casual ways again. Let me know if you are familiar with Fourwing Saltbush. Where does it grow? Have you ever marveled at the thousands of winged seeds densely crowded at the tops of these shrubs? And then satisfied an irresistible urge to strip dozens of skinny branches of those ripe seeds, tossing them in the air like confetti? If so, please share.

As always, thanks for stopping by!

Late Bloomers …. Fall’s Flowery Foothills

September 26 & 27, 2023

It’s hard now to imagine how extremely hot and dry the summer was this year. Without even a spittle of rain, the 100+ degree temps for weeks effectively suppressed the usual mid-season bloomers in and around the Albuquerque foothills/East Mountains. Even invasive plants, like goathead and tumbleweed, remained dormant or failed to germinate all together. It looked like winter browns had arrived early.

Then in less than a week, a small rain followed by several long downpours flooded the parched landscape, transforming browns to greens. You’ve heard this from me in a few earlier posts, but it was magical, and a reminder about the resiliency of desert vegetation.

Here’s a few pages highlighting a handful of the Late Bloomers I recorded in only 2 days. More than 2 dozen species had sprung back to life, setting flowers at all stages of accelerated vegetative growth. The landscape seemed wide awake. If plants could talk, I imagined them laughing while excitedly chanting, “hurry, hurry, hurry!” Only their roots prevented them from dancing!

In addition to the species on these journal pages, there are many (more) composites, native grasses, shrubs and sub shrubs, small forbs from Spring and early Summer actively growing and blooming right now, and (of course) the weedy invasives are growing and blooming with wild abandon.

Random thoughts and wonderings ….. are pollinators still hanging around …… or ….. how many of today’s bloomers are self fertile …… are local birds, insects, reptiles and mammals that depend on earlier summer pollen and/or fruit and seed production stressed with this timing change/availability of food sources … will there be noticeable shifts in species composition, including plants, insects, reptiles and animals (including birds) ….. what species can and will adapt to changes, and how quickly ….. etc. The answers to these and many more questions are probably best answered in coming years, if it’s even possible to answer them at all.

Have you observed vegetation anomalies that may be influenced by changes in climate? If so, please share your observations and where these changes are taking place. Meanwhile, keep your eyes wide open.

July “Littles” ….. Blooming flowers attract famished butterflies

June’s hot, dry weather slipped stealthily into July as we became mired in one of those infamous heat domes for weeks. Our rabbitbrush shrubs, usually late summer bloomers, burst into piles of brilliant yellow flowers a full month before normal, and for the first week of their premature bloom, not a single pollinator was in sight. I was so concerned the over abundance of nectar would dry up, pollen would blow haphazardly away, and seeds wouldn’t form. Then one morning I woke to find hundreds of butterflies, weevils, flies and bees flitting, crawling and buzzing about, nearly covering the shrubs completely in a pollination frenzy! How did they know? Where did they come from? What a relief for me, but it must’ve been an unimaginable relief for all of those pollinators that happened upon our oasis in the desert.

And so it went, all month…. bursts of early blooms rapidly completing their floral life cycles, thanks to urgently feeding pollinators.

This is how I remember July, with everything in bloom at once, the air full of pollen and pollinators. It was quite a sight!

Once again, a big shout-out to “Made by Fay” for the inspiring “Littles” idea! Stay tuned for the next installment of “Littles.”

Excitement on all levels! Welcome Big Rain and Big Bugs.

August 8, 2023

Was it just 2 days ago when I posted “this year’s monsoons didn’t materialize.”??????? This is headed our way! The skies are grumbly, full of lightning, big fat rain beginning to drop. Wow! This is what we had seconds before posting. We’re that little blue dot east of the big red!

And if that isn’t enough excitement ….. Big Bug Alert! you should’ve seen this giant root borer that paid us a visit a few days ago!

Ok! I’m posting quickly before the lightning wipes out the Wifi on Sandia Mountain.

Thanks for sending rain!

The Forecast: Scattered Green Mixed With Dry Brown Dust

August 6, 2023

Sharing my pages from today’s short hike up Cedro Creek, on the fringes of the Manzano Mountains. The water shortage here and all around us has become dire; soils are cracked and dry and beginning to take flight with the barest puff of wind.

Since we last hiked this area (a few days shy of a month ago), the scattered shallow pools of water have either evaporated completely or made a retreat underground, where there may be just enough water to wet the riparian area. All the tender flowering plants have disappeared; many have been able to set seed in hopes of a wetter year to come. With this premature wrap up to the summer season, the birds, bees and butterflies have moved on; hopefully up in elevation where food may still be found.

Our summer monsoon season just didn’t materialize (yet?). But despite the hot and dry conditions, we did manage to find a few leafy green shrubs. The massive cottonwoods appear to be doing well (must still be sufficient groundwater). In the cooler parts of the canyon, there are berries hanging on the 2 species of juniper trees. Acorns have begun to mature on several oak species, even though there are many that have withered; is all of this earlier than usual?

At the trailhead, tucked in a swale where water (when it comes) can collect, I was surprised to see some very stunted smooth sumac. Already showing off their clusters of juicy red berries, the plants are barely a foot tall. This species can rapidly grow to heights of 16 feet. Maybe flowering and fruiting on such short plants is a type of survival mechanism this sumac exhibits when conditions are not favorable? I will be able to watch this little grove over the coming years and maybe answer that question.

Then further up the canyon, about 20-30 feet above the riparian area, Gambel’s and Wavyleaf oaks are growing their acorns. That’s encouraging news for the squirrels who collect and cache them in overwintering nests.

It’s been a challenging year.

What differences in nature have you been noticing where you live? Do you think our changing climate has played a role in driving the changes? Have you observed not only negative but positive affects? I’d be very interested in knowing!

As always, thanks for following!
