A Beachcomber’s Musings on Floridian Dune Ecology

Discover the resilient beauty of Florida’s dune sunflowers through the eyes of a beachcomber. Uncover the secrets of Helianthus debilis, a symbol of hope thriving where sea meets sand. Join the coastal dance of life.

Encounter with Helianthus debilis


Strolling along the beachfront of Patrick Space Force Base, Florida, my gaze is captivated by a cluster of dune sunflowers, or Helianthus debilis. These hardy perennials are native to the coastal sand dunes of the southeastern United States and have made a home amidst the sandy grains where few dare to take root.

The Sunflower’s Domain


Helianthus debilis, distinguished by its large, yellow ray florets and dark center disks, thrives in this challenging environment. The dunes provide a unique ecosystem, where the sunflowers can withstand high salinity, shifting sands, and the full force of the sun’s rays. Their deep root systems anchor the sandy soil, helping to prevent erosion and maintain the integrity of the dune landscape.

Adaptation and Survival


The dune sunflower’s adaptation to its coastal environment is a marvel of nature. Its silvery-green leaves are covered with tiny hairs, reflecting sunlight and conserving moisture. The flowers bloom throughout the year, ensuring a constant presence of color along the dunes. Their hardiness is a testament to the sunflower’s evolutionary success in a habitat where freshwater is scarce and the soil is nutrient-poor.

A Native’s Role in the Ecosystem


As a native species, the dune sunflower plays a crucial role in the coastal ecosystem. It serves as a food source for local wildlife, including insects and birds, and its presence helps stabilize dune formations. The ecological value of Helianthus debilis extends beyond its beauty, as it contributes to the biodiversity and resilience of the coastal dunes.

The Dynamics of Dune Life


The life of a dune sunflower is inextricably linked to the ebb and flow of the coastal environment. Each plant is a microhabitat, supporting a range of organisms from the larvae of the dune butterfly to the burrowing beetles that find refuge in the sand. The interaction between the sunflowers and these creatures creates a dynamic web of life, each species depending on the others for survival.

Reflections on Resilience


The dune sunflower’s ability to flourish in such an austere environment is a profound reminder of the resilience of nature. As I observe the sunflowers, I am struck by their tenacity, their willingness to face the elements head-on. They are a beacon of life in a place where existence is a daily challenge, and their perseverance is a lesson in the art of endurance.

Conclusion: A Testament to Nature’s Ingenuity


As the sun begins to set, casting a warm glow over the dunes, I take a final look at the Helianthus debilis. Their scientific wonders and ecological im portance leave a lasting impression. They are not just flowers; they are a testament to nature’s ingenuity, an embodiment of the delicate balance between life and the environment. These dune sunflowers are a symbol of hope, a reminder that in the face of adversity, life finds a way to not just survive, but to thrive.

Rincon Flame: The Southwestern Paintbrush’s Desert Dance

Step into the Rincon Wilderness with me, where the Southwestern Paintbrush blooms amidst the ancient stones.

Discovery in the Rincon Wilderness

In the embrace of the Rincon Mountains, east of Tucson’s hum, lies the Rincon Wilderness, a tapestry of desert life and geological marvels. These mountains, one of the “Sky Island” ranges cradling the Tucson valley, are less rugged than their siblings, the Santa Catalinas and the Santa Ritas, offering a gentler invitation to explore their secrets.

Happy Valley Saddle’s Floral Jewel

Amidst the rugged beauty of Happy Valley, a hidden corner in the quilt of the Rincon Wilderness, a singular red-orange glow caught my eye. There, among the lichen-encrusted boulders, stood the Southwestern Paintbrush, Castilleja integra, its flamboyant bracts a fiery contrast to the muted greens and grays of its surroundings.

Portrait of a Parasite

This herbaceous perennial, with its soft downy coat, is a paradox, both painting the desert with life and leeching it from others as a hemi-parasite. Its roots, entwined with those of other desert dwellers, tell a tale of survival that’s as old as the hills themselves.

The Brushstrokes of Evolution

Each leaf, narrow and dusted with hairs, speaks to the adaptive artistry of nature, designed to conserve precious moisture. The flowers, with their extended blooming season and generous nectar, court the hummingbirds who dance between the blooms, pollinators in this ancient symbiosis.

A Symbiotic Canvas

The Southwestern Paintbrush, with its colorful allure, draws more than just winged admirers. Its presence among the rocks is a reminder of the complex ecological web of the Rincon Wilderness, a part of Saguaro National Park’s rich mosaic

Autumn Evening Hike, turning home

through Devil’s Kitchen to Lucifer Falls

In this third part, we continue hiking Treman gorge, approaching Lucifer Falls, viewing another waterfall further downstream and returning to the trailhead.

 Tiny Trumpet, unknown

I have never achieved a satisfactory capture of the waterfall in the Devil’s Kitchen, a place where the creek flow is diverted south by a projecting ridge. Less than 100 feet later the easterly direction is regained where the water plummets over Lucifer Falls.

The annual in fall of rock in Devil’s Kitchen uproots and crushes plants growing there. There is scant soil, the roots of this shiny purple trumpet bloom took hold in a microscopic crack. The plant is so thin, the flower so tiny it is lucky my gaze found it.

Click link for my fine art print “After the Rain: Showy Lady Slippers.”

After searching all my plant identification references, this plan is unknown to me.  Please help with identification. The bloom is 1/4 inch long.

Not far away, these asters grow from a slightly wider crack.  Pam pointed them out to me. I was drawn by the striking color difference of the heads growing from a single stalk.

Click link for my fine art print “Purple Asters.”

As trail winds around the ridge a stone wall rises on the right and for good reason.  The stream shortly reaches the brink of Lucifer Falls, 115 feet high.  Gorge walls fall away, the trail steepens.  Here is the view from the trail next to the brink.

At hand, on the right, a growth of ferns has survived many seasons.  Flowering plants are, in geological time (across billions of years), a relatively recent development compared to these non-flowering ferns.  The first flowering plants appears 120 million years ago compared to the first ferns, 360 million years ago.  Oddly enough, the spread of flowering plants affected evolution of ferns, an increase of fern speciation in parallel to the rise of flower plants.

While descending the stairs next to the falls brink, look to the right to see this ecosystem, a result of water seeping from the sedimentary rock stratification.

Here you can see how, at lower flow levels, the inactive sections of the fall lip become a garden.  In our climate, the entire brink is active for rare and brief intervals during spring thaws.  Note how, closer to the active brink, the grasses give way to mosses.  Where grasses grow the brink is almost never active.

The trail wall is a lighter color than the cliff, this is how you can see, on the right, the steep trail descent.

Pam and I turned around here.  This is some work I did August 2014 of a notable fall downstream from Lucifer.  I used the 24 mm Canon lens here, cropping the image.  My goal was to include the stair, for interest, with sunlight on the upper stairs; the water in shade.

Click link for my fine art print “Woodland Falls.”

Myrtle borders the trail as it rises from the gorge entrance.

Tree trunks fallen from the gorge walls are left to decay, restoring the soil.  The trunks are covered by moss among a thick growth of myrtle and a few ferns.

To finish, here is an image that may broaden your understanding of sunflowers. These smaller, ornamental sunflowers are, at first, difficult to place. Look carefully at the center, composed of many tiny flowers (florets). In crop sunflowers each of these becomes a seed. In this image, shiny beetles are feasting.

Autumn Evening Hike Part 2 of 3

Water runs through it

Portrait of Mill Falls

In part 2 of this series, we return to the starting point. Siting of a water mill requires immediate access to the potential energy of falling water, something called “head.” Upper Treman Park was once a prosperous hamlet with the mill as the kernel. Today, the head that drove the mill is a lovely cascade behind the substantial and intact mill building. Easy walking distance from parking, this is a well-known park feature.

Here are three versions of a portrait of Mill Falls using different lenses for varying effects. All were taken in the same season and approximate time of day, being early evening.

This is the uncropped image used in part 1 of this series. I found the secondary cascade a distraction. Exposure of the secondary is difficult to balance against the primary and more shaded primary.

Stone Span

Let’s return to where part 1 left off, the stone bridge across the eastern side of the gorge entrance gallery.

This segmental arch is an illusion, the beautiful stone work is the facing of the concrete structure that carries to load of the stone, itself and visitors.

My composition emphasizes the mass of rock wall above the bench and into which it is placed.  The limestone slabs are from a different source, they are not built from the material removed from the cliff.

Seeds and Flowers

A dandelion on steroids.  If you can help with identification of this plant, please post a comment.

Look Back!!

Many first time visitors do not look back to appreciate these scene.  When we give advice, our recommendation is to return on the same gorge trail.  The different viewpoints make for a fresh experience.

They are like people, sitting there.  Kenneth Graham’s genius, in writing “Wind in the Willows”, was to recognize the likable characteristics of the toad.  I find myself concerned about their survival, although they must survive.  Earlier in the season they are pea sized.  I resist an inclination to move them to what may be a more promising location, preferably with a stone house and chrome brilliant motor car.

Autumn Evening Hike Part 1 of 3

It started with running water…..

Over the weekend the handle of our 60 year old Delta brand kitchen faucet broke off, since we moved here I rebuilt it once and replaced the stainless steel sphere, the central control of the mechanism.  The stem of the sphere must have been faulty because it snapped. Monday, I visited Lowes and the sphere was not in stock.  Just wanting to fix the faucet, I skipped the usual vetting of a new product and grabbed the exact same Delta faucet which was, just like the sphere that broke, made in China.  The next step up in (questionable) quality was three times the price.

Running Water

Yesterday I installed a new faucet in the kitchen sink, a straightforward and unpleasant task that took most of the day.  Late afternoon, while resting up, I brought up the idea of a hike and Pam reminded me we had another clear September day.  Last week, I headed out to capture the Mill Creek waterfall of upper Treman Park at the perfect time of day.  It was a day such as this, warm, a cloudless sky, minimal breeze.

Mill Falls
Pam reminded me this evening I was trying to capture the Mill Waterfall of Upper Treman Park at the perfect moment when the sunlight glazes the pools.

I need to get in place a bit earlier.  Previously, I used a 24 mm wide angle lens and, today, mounted the EF 70-300mm f/4 – 5.6L USM lens on the Canon EOS 1DS MarkIII.  Did not have time to sort through the ND filters, so left the UV on.  The waterfall is in a glen, shaded from direct light at this time of day, sun low in the west.  Given the low light, to save time, I decided to set ISO to a low value (125), set lens to the widest angle (70 mm), and frame the shot using the heavy Manfrotto tripod with ball head.

Needed to crop the image for the above result, still not perfect.  I am seeking to full the entire pool in that glow.

Mo's Bench
Towards the end of her life, my Mom waited for us on this bench while we walked. She enjoyed the sound of the creek, watching and chatting with passerbys. There some out of focus goldenrod right foreground. I frames the shot to catch the flowers and crop out a tree trunk.

Hiking the Gorge Trail

Instead of putting the gear away, I carried that heavy setup on the hike.  The strap around the neck is a lot of stress if it hangs.  With the gear cradled in the crook of my arm it is bearable.

Foot Bridge
The creek is spanned at several points by these stone footbridges, the work of the Civilian Conservation Corps, as are all the gorge trails. This bridge was restored last year. It leads to a marvelous grove of Sycamores.

Needless to say, the pace was sedate.  Pam spent most of the time walking ahead and refusing to be in any shots.  These past weeks, rainfall was light, so the creek is low.  This low flow is a necessary element to a perfect waterfall image.

Golden Rod
A single stem of goldenrod, ther are hundreds of species of this relative of the aster.

I get some great macro shots with that lens.  With just the UV filter, it is quite fast.

Ferns, Lichen, Gorge Wall
The gorge wall rises to the right of the path.
Foot of the Gorge Wall
Very little of the gorge walls do not support thick growth of mosses, lichen, ferns, flowering plants of all kinds. I don’t know offhand the name of the cnetral plant growing from the base of the wall.

In the Gallery

Creek Pool
Shaped by whirlpools during high flow, the curves recall flowing water.

A memorable feature of upper Treman Park is the dramatic gorge entrance.  When the glaciers melted, 10,000+ years ago, enough water flowed through this watercourse to wear away several hundred feed of sedimentary rock to form a gallery, or hall, with towering, crumbling, walls on either side.

This evening the light was low, the water seemed dead in that it was clear and did not glisten or ripple.  I used these conditions in the above shot to emphasize the structure this pool.  Located at the foot of a waterfall, at high water, the falls fill channel and this pool is carved by river stones carried in the current.  At lower water, the pool is exposed.
