Frost Flowers -- Nature's Winter Artistry

Frost Flowers -- Nature's Winter Artistry

Written by Jenna Atma, Naturalist

Frost "flower"

After a hard frost, like we experienced here at Warner Parks this morning, many plants retreat into a winter dormancy. But a few species, including a native perennial called White Wingstem (Verbesina virginica), will create a stunning spectacle when the temperature drops in the form of "frost flowers", which also earns White Wingstem the nickname "frostweed". 

Frostweed with its signature winter frosted base.

Frost flowers, formed in a process called crystallofolia, are a fascinating natural phenomenon that occurs when conditions are just right. The moisture in the plant's stem freezes, producing beautiful feathery-looking ribbons that appear to spill out from the stem, often close to the ground (where their roots continue to supply more water to the stem). White Wingstem in particular holds an ample supply of moisture in its stem, making it particularly adept at creating these ephemeral ice flowers.

Why do these plants create frost flowers? Although these formations are of course beautiful to observe, there are several potential practical reasons for them to occur as well, like helping to insulate the plant and protect it from harsher winter conditions. These frost flowers can also provide a source of water for some insects during cold winter months; a connection between plants and animals within the ecosystem.

If you look closely at the plant base where the frost flowers are formed, you may notice that the main stem itself doesn't split. The outer layer, or "epidermis", will rupture to release built-up pressure from the sap rapidly freezing. Plants that live in climates that freeze seasonally have a few options for survival: with annual herbaceous plants, the main plant dies while leaving a protected seed bank behind. Longer-lived species, like frostweed, will either remain active or become dormant during the winter. Some plants that remain above ground require mechanisms that allow them to persist in the cold, with one strategy being crystallofolia.

Like snowflakes, each frost flower is different, with intricate patterns and shapes that are unique between every plant. The fleeting nature of frost flowers has led many people to think of them as reminders of the impermanence of life, and encouraging appreciation for natural beauty around us, no matter how transient it may be.

Every frost flower is unique

The best time to observe these magical occurrences is during the first few frosts of the season, typically in late fall to early winter. The best places in Warner Parks to observe frost flowers are the Nature Center meadows and the field in Long Hollow along the Old Roadway loop in Edwin Warner Park.

For all those who appreciate the subtle beauty of the natural world, the White Wingstem and its frost flowers remind us to pause and admire the intricate details to be found in nature, and the new discoveries that the winter season may bring. So, next time the frost settles in, keep an eye out for these stunning frozen flowers that remind us of the beauty and resiliency of the natural world.

Where are the Monarchs?

Where are the Monarchs?

Written by Elyse Dilks, Naturalist

Where are the monarchs? It is a question that I have been asking myself a lot recently. A question quickly spiraling into other questions… Have they started migrating yet? Are they okay? Have they stopped flying through our parks? Did Hurricane Helene delay them? Are there even any monarchs left? My mind has been a whirlwind of concerns as I formulate reasons as to where they could possibly be. Here at Warner Parks, we are accustomed to seeing hundreds of monarch butterflies in the spring and fall seasons. They flutter around our meadows, visiting flowers and searching for the perfect milkweed leaves to lay their eggs on. I’ve seen females go from plant to plant laying eggs. They can lay anywhere from 100-300 eggs and when conditions are perfect, 1 egg per plant. However, where are the females to lay their eggs?

There have been a couple of sightings this fall season. One seen at Long Hollow and one near Butler’s Field. There was one monarch in the beginning of September, the 9th to be exact, that left her mark within our organic garden. Upon 3 of our healthiest milkweeds, 2-4 eggs rested on separate leaves. In total there were 7 monarch eggs. I was ecstatic! They were finally here! There had been speculation that a cold front in the north delayed the larvae development and start time of the monarchs’ usual migration period by at least 10 days. I wondered if she was the early bird and if more were soon to come after having been delayed. However, days of waiting and watching have now turned into weeks. Nothing. Those eggs I hoped to watch grow during their first phase of life were quickly eaten within the first couple of days. A tasty snack to ants, wasps, beetles, parasites, and many others. The early bird, or in this case the early monarch, did not succeed. Nature can seem so cruel, but it is simply being natural. I cannot help but feel sorrowful and a sense of dread lingers knowing that at this point, those eggs were the only ones laid here at the Nature Center. Maybe a few sneaky monarchs wandered to our meadows and laid eggs that were successful, but a cloud of doubt fills my mind.

This year has turned out to be a major hit to the monarch populations. After a couple of heavy cold spells in January of this year, many monarchs from the roosts of Mexico did not make it. Scientists with the World Wildlife Funds estimated there was a 59% decrease in population from the previous 2022-2023 year. This estimate was based on the number of acres inhabited during the winter roosts in Mexico, with 2022-2023 having 5.5 acres used for roosting as opposed to this year’s 2023-2024 season only making up 2.2 acres (“Eastern Migratory Monarch Butterfly”). To give some perspective, the largest roost documented, spanned 18 acres. Since being documented and observed, monarch populations have been decreasing for the past 30 years, due to climate change, deforestation, and habitat loss. I worry that now it has become too noticeable that something is amiss.

Here in Warner Parks, we did not see a single caterpillar at our monitoring sites in 2024. Any eggs seen were snatched within the snap of my fingers. Many of us have been aware of the monarch populations decreasing, but we still saw them in large enough numbers. My brain never truly processed what it could result and now I am witnessing it firsthand. The lack of monarchs poses to us a cautionary tale. The absence of their presence foreshadows much larger problems for not just monarchs but to all living things in this world, which has caused me to realize the privilege of observing a monarch perform pirouettes in the air, carefree to us worried onlookers. As their populations dwindle, I watch our milkweeds begin to reach to high to the sun without monarch larvae to help prune their leaves. Like Icarus, their once bright green leaves scorch and shrivel, their bodies covered in black mold. Where did the mold come from? Greedy aphids feast upon the milky latex of milkweed and excrete a byproduct known as ‘honeydew’. A sticky but delicious delicacy for many organisms. While aphids’ honeydew coats the milkweed, sooty mold seeks the opportunity to daintily rest upon the plants and eat away at the sugary treat. Leaving behind the decrepit image of a burnt corpse. Unhabitable and undesirable.

I refuse to leave this on a sad note. In my heart, I believe the monarchs simply skipped Warner Parks this year and rushed down to Mexico to roost after potentially being delayed by cold fronts and a hurricane. Maybe next year as they travel up north, there will be a population explosion. To you as the reader, consider growing milkweed and let your yard flourish with native plants. If you live in an apartment, plant natives in pots or other outdoor containers. Even if the Monarchs don’t visit, at least you are providing food and shelter to other species that may be just as affected by the changes of our world. If the resources are there, such as Milkweed and other native flowers to forage, who knows what could happen. Nature likes to be unpredictable. I prefer it that way. Untamable just like the wild Monarch that flutters away as you catch a glimpse, leaving you hunger for more.

Leave the Leaves

Are you dreading having to rake your leaves over and over again this fall? Well you're in luck, because the "Leave the Leaves" initiative says you don't have to! 

We don't often think about the fall leaves covering our yards as serving much of a purpose; but in fact, they are massively beneficial for many reasons. So before you grab your rake and jump into the usual fall clean-up routine, consider leaving your leaves in place--it may actually be the best thing you can do for local wildlife.

1. Leaving leaves creates habitat for wildlife

One of the primary benefits to leaving your leaf litter in on the ground is that it provides crucial habitat for a wide variety of wildlife. Insects and critters such as beetles, spiders, salamanders, lizards, and many other creatures use the decaying leaves and for shelter and a way to find food. In turn, birds, mammals, and other predators also find food amongst the leaves, making leaf litter an important place for many animals to find shelter and sustenance during the fall season.

One of the many benefits of leaving leaves during the winter is that you might find your garden full of butterflies in the following spring! many insects, including butterflies, have larvae (like caterpillars) that live under the leaf litter in fall. 

2. Leaving leaves supports soil and plant health

The decomposing leaves offer more than just a shelter for small critters; they also add important nutrients back into the soil. Decomposing leaf litter creates a natural mulch that helps to suppress weeds while fertilizing the soil as it breaks down. Animals, plants, and fungi that consume decaying matter, known as "detritivores", also help to break down the leaf litter, which helps speed up the decomposition process to make your yard's soil more fertile and thus helps plants grow in the spring.

If you must move your leaves from the lawn, considering using them as a natural mulch for your garden or in landscaping. Mulch can help mediate soil temperature by keeping plant roots warmer during the winter and cooler in the summer. Mulching also keeps the soil moist, which is especially helpful during hot weeks with little rain. Leaf litter is a free and eco-friendly mulch option you can use!

3. Leaving leaves promotes a natural landscape

Allowing leaves to remain where they fall can help promote a more natural landscape to flourish. Traditional lawns limit the amount of natural processes that can occur, and allowing leaves to stay is a fantastic way to encourage your yard to be more beneficial for local biodiversity and help support many more organisms than it otherwise could.

4. Leaving leaves helps reduce our environmental impact

Raking and bagging leaves contribute to the growing problem of yard waste in landfills. By leaving leaves in your yard, you’re helping to reduce the volume of yard waste that ends up in landfills. This small change in your yard maintenance routine can be a simple, yet effective way to make your lawn care more eco-friendly. And gas powered leaf-blowers are big polluters - not only are they noisy and disrupt the critters living in your leaves, it is also estimated that one hour of operating a commercial leaf-blower emits smog-forming pollution equal to driving a car about 1,000 miles!

While the temptation to rake up those autumn leaves is strong, especially if you’re aiming for a pristine lawn, there are compelling reasons to reconsider. By leaving leaves in place, you’re supporting local wildlife, enriching the soil, reducing waste, and fostering a more natural landscape. This simple act of letting nature take its course can have a profound positive impact on both your yard and the environment. So, this fall, think twice before reaching for that rake—your local ecosystem will thank you!

Hooked – A Story of Snake Ensnared

Hooked - A Story of Snake Ensnared

Written by Elyse Dilks, Warner Parks Naturalist

Yes, this is a story about a snake, but more importantly, this is the success story of a Northern Watersnake that had been hooked by a fishing line here at Warner Parks.

To unveil the full story for this blog, I dug deep by interviewing those involved with this snakey incident, comprising mainly of our very own Warner Parks staff and the Nashville Wildlife Conservation Center.

It all started when one of our Naturalists, Rachel Carter, was at the Little Harpeth River working with our summer camp kids. There, she encountered a teenager who was getting ready to fish nearby. She ushered him to portion of the creek a little further away from the kids. It was shortly after this moment that Rachel C. heard,

“Snake!”

Rachel C., upon hearing this, turned towards the direction of the call and saw a large Northern Watersnake (Nerodia sipedon) swimming in the water near the fisherman. Watersnakes are a common occurrence in our parks, so--not yet understanding the full situation--Rachel C. exclaimed excitedly,

“Oh my gosh look at that snake! That’s a huge snake!”

“No, it ate my fishing line… it ate my lure!”

Now realizing the dire situation at hand, Rachel C. watched as the snake, hooked in mouth, began swimming towards a pile of rocks, dragging the fishing line with it. Although Rachel C. “has a healthy respect for snakes” and describes them as “beautiful creatures that are misunderstood and receipients of irrational fears”, she still felt inexperienced in her abilities in catching a snake of this size. She decided to call Rachel Anderson, another park Naturalist, and myself for guidance on what to do. As Rachel C. was frantically trying to find a solution, the young fisherman beckoned for his mother to come back. Knowing he would have to cut the line and potentially ruin their chances of rescuing it, he protested, but then both to his and Rachel C.’s dismay, they watched as the line snapped…

Over at the Nature Center, Rachel A. had received the phone call from Rachel C. and was headed towards the location where the snake was. As Kassie, our front desk Naturalist recounts,

“Rachel A. ran by, saying ‘I have to go save a snake!’”

On Rachel A’s. way, she bumped into two of our Summer SWEAT crew members, Austin and Lars, who were eager to help with the rescue. They appeared at the scene and quickly scouted out the snake with Rachel C.’s help. They were able to safely capture the snake, and brought it back to the Nature Center where they created a makeshift container to hold it: a simple bucket with a towel taped around the top with holes cut into it for better airflow.

Two of our staff members, Kassie and Caroline, started calling different wildlife rehabilitation centers and even local veterinarians to see if they would take in the snake. At this point, the snake’s condition was dire. It had swallowed the hook and only a string could be seen hanging from its mouth. Everyone knew that it needed medical professionals to removal the hook. After many calls and no one able to take it in, the name Debbie Sykes, a former Warner Parks employee, was mentioned.

Debbie seemed like the right person for the job. She created the Nashville Wildlife Conservation Center (NWCC), is an ER Licensed Veterinary Medical Technician and takes in all sorts of injured wildlife. Once Debbie was informed of our emergency, she assured our staff that she would be able to take the snake, but not until the next day. Because of this, Rachel A. took the snake home, kept it overnight, and delivered it to Debbie the next morning.

Once it was in Debbie’s care, she immediately took the snake be radiographed, which revealed that the hook had punctured through its internal wall and was now stuck in its neck. A surgery was performed by a veterinarian, and the hook was successfully removed. Debbie stated that “After a couple of weeks of pain medication and antibiotics, along with proper housing to decreasing stress and promote natural behaviors, he was deemed ready to go.”

On July 27th at 9:09am, Rachel A. and I watched the watersnake be released back into the Little Harpeth River by a NWCC volunteer. To say it was an astonishing sight observing the snake be released, is quite frankly an understatement. This was a snake that had all odds against it: swallowed a hook, impaled internally, went through surgery, and was then kept in captivity for a few weeks. These are highly stressful events for even a person to go through, so imagine what it may have been like for this snake!

As Rachel A. remarks, “I was impressed on how resilient of a creature it is,” which I think perfectly encapsulates everyone’s opinions on our mighty little legless friend.


Some may wonder why we would intervene and help this snake out? Well, here is the simple and cold truth: It would have died without our intervention. When an animal gets hooked or wrapped up in fishing line, it interferes with its daily life. Its mobility is lowered, it can have difficulty eating, or even have internal complications arise. As Rachel C. stated,

“I feel we were obligated to help that snake. It was a victim of human actions, so therefore humans were responsible for doing everything they could to undo the damage they caused.”

Everyone I talked to agreed that intervening was the right call. As Lars (SWEAT crew member) mentioned,

“It would have been different if the snake was injured by another animal or was just old, but it had fallen victim to something that was never meant to affect it. Something that it couldn’t avoid or understand.”

Although it was a happy ending for the snake and all those involved, oftentimes there are different outcomes to a story. While in the midst of typing up this blog, another animal was found hooked at our Little Harpeth River: this time, a juvenile Belted Kingfisher. The young bird was seen dangling in a tree by a fisherman, having been hooked by a line that had been tangled up in the branches and abandoned. Warner Parks staff once again hopped onto the scene. Unfortunately, in this case the Kingfisher was not as lucky as the watersnake, and had withstood too great an injury to have been rehabilitated. A heartbreaking end to pair with the success story of the Northern Watersnake.

Both of these fishing hook encounters sparked conversation among our Nature Center staff. Two different hooked animals, with two different ends to their stories. Warner Parks is a nature sanctuary, and we do not allow our flora and fauna to be harmed or removed. When interviewing staff, I would often ask them: "What is one way you think would have prevented this situation from happening again?" Some, when prompted with this question, suggested on banning finishing in our parks. Others want to urge park fisherman to cleanup their fishing supplies, leaving nothing behind. Some staff were unsure on the best course of action. As Kassie put it,

“We are a city park and nature sanctuary, should fishing be allowed when we don’t allow the harming or taking of our animals?”

 We wish there was a simple solution. However, it is important to note that Warner Parks are a part of the Metro Parks system. Because of this, fishing in any Metro Park is allowed as long as anglers have a required, valid fishing license. Even though we do not have a definitive solution to this issue, here are some ways you can help prevent an incident like our hooked snake and kingfisher friends experienced from ever happening again:

- Leave no trace! Clean up after yourself and others, and do not leave anything behind. If out fishing and your line snaps or a lure gets caught, please retrieve it and discard it into a proper waste container.

- Be aware of your surroundings. If you are in a location where you could encounter animals other than fish, be mindful of where you cast your line and be vigilant as to what is being attracted to it.

- If you do catch something that’s not a fish and are unsure how to extract it, please contact the Nature Center at 615-862-8555 or wpnc@nashville.gov. Do not cut your line or leave a hooked animal in the Park.

A big thank you to the Nashville Wildlife Conservation Center for being our helping aid for both the Northern Watersnake and Belted Kingfisher.

The Great Cicada Emergence

  

The Great Cicada Emergence

By Jenna Atma, Warner Parks Naturalist


Something exciting is happening in the park—the first sightings of some very special cicadas! Whether or not you've already heard about “the big cicada emergence” this year, you may very soon notice several of these small, red-eyed creatures buzzing around in the trees or crawling on the sides of plants and buildings. 

You've probably seen or heard cicadas before, especially if you've spent at least one summer in Tennessee, but the cicadas emerging this year are part of a special group. These cicadas are called Periodical Cicadas and are a species that spends the first part of its life, a whopping 13 years, completely underground, only emerging to sing and find a mate. They’re called “periodical” because they only emerge above ground on a 13-year cycle, based on their lifespan. Because they’re cyclical, we can predict when they will emerge, and each of these “broods” is numbered. In 2024, we’re experiencing “Brood XIX”!

Discarded exoskeleton (outer skin) of a cicada nymph

Many cicadas spend the majority of their lives in nymph-form, drinking nutrients from tree roots underground. Once they are ready to emerge, they dig their way out of the ground and crawl up the sides of plants, trees, and buildings, and shed their nymph exoskeleton, similar to a butterfly hatching from a chrysalis or cocoon. They will then perch nearby and wait as their shells harden and wings dry out. Then, off into the night they fly, leaving their exoskeleton behind! You can watch this process in the time-lapse video below:

Time-lapse video of a cicada emerging from its nymph exoskeleton

However, not all cicadas spend years and years underground. Many of the cicadas you see and hear every year are “annual cicadas”, which mature in just 2-5 years. This means that annual cicadas emerge unsynchronized from each other, whereas the periodical cicadas have synchronized broods and all emerge en masse in the same year as the rest of their "brood". 

An annual (also "Dog-day") cicada, which is larger and has black eyes with green markings

Although cicadas are loud and can be rather alien-looking, there’s no need to be afraid of them. Cicadas don’t bite defensively or have any stingers, nor are they poisonous. In fact, they are quite harmless! Large broods of cicadas emerging can also provide a valuable food source for birds and other insect-eating animals, and the tunnels that cicada nymphs dig helps aerate the soil, which can have a positive impact on plant growth and available soil nutrients. So don’t worry—cicadas aren’t going to harm your gardens or trees!

Freshly-emerged cicada drying its new wings at Warner Parks

So where can I find cicadas, you may ask? You'll be able to see (or mostly just hear) both periodical and annual cicadas during early summer evenings and nights here in Tennessee. Brood XIX has the largest range of all the periodical cicada broods, and can be found in many parts of Tennessee. Cicadas from Brood XIX will also be emerging in many other states in the Midwest and eastern U.S.; and along with them, another brood of periodical cicadas will be emerging as well, a species of 17-year cicadas called Brood XIII! Although we won’t be able to experience them here at Warner Parks, these two broods will be overlapping emergence years in parts of their ranges for the first time in 221 years, which makes this year a very special one for cicadas indeed! 

So take some time in the evenings this summer (early May – late June) to go outside and listen for the chorus of cicada calls, and enjoy these amazing little creatures on this very special year!

Want to come and celebrate or learn more about cicadas here at Warner Parks? Join us for our upcoming Cicada Celebration on May 23rd and 24th from 1-3pm, or visit our upcoming program and events schedule to discover other fun happenings here at Warner!

Solar Eclipse 2024

The 2024 Solar Eclipse

By Wesley Roberts

Photo of the 2017 solar eclipse by Wesley Roberts

The second solar eclipse within 6 months will be visible in Nashville on April 8, 2024. Although we are not in the path of totality, we can expect the sun to appear 95% covered by our moon. The Nashville sky will become much darker than a normal day, and millions of people throughout our area and North America will enjoy this astronomical event.

Many people understand what is happening. As the moon moves in its orbit around the Earth, it will pass directly between the sun and our planet. The shadow cast by the moon on to North America will move from southwest to northeast along a path from Mexico through to New England. Along the path of totality, where the moon appears to completely cover the sun, it will be as dark as nighttime for a few minutes and stars will appear in the daytime sky.

A most important aspect of understanding this phenomenon is the accuracy of science. There are very few events that take place in the future for which we can have near absolute certainty of their occurrence. Science gives us the opportunity to make reasonable predictions to which we assign confidence based on the fact that results are testable. For example, the science of meteorology gives us reasonable expectations about upcoming weather and the science of botany helps us to have reasonable expectations that we can grow food. Neither of these is 100% definite. The prediction of an eclipse is as close to 100% as we can get.

In the 4th century BCE, Chinese astronomers began predicting eclipses accurately (with at least one king, Zhong Kang, beheading two astronomers who failed to predict one). The observations of a lunar pattern called the “Saros Cycle” was observed by ancient cultures around the world and enabled the forecasts to proceed. Today we can accurately state the eclipses that will occur for the next several thousand years.

As science is currently attacked from many disciplines that include an unwillingness to accept its rigid protocols and openness to revision based on data, the solar eclipse is a strong testament to the power of this branch of knowledge. On April 8, 2024, this event WILL HAPPEN (to be accurate, an asteroid of the “Don't Look Up” variety could strike, or a few other cataclysmic events, but these are unlikely to the point of being dismissible). As you are getting comfortable in your observation place, wearing your safe eclipse glasses, finding yourself in awe of the power of this marvel and counting the stars that almost magically appear in the daytime sky, be aware of the values that scientific discoveries have added to the quality of our lives. Most of all, enjoy this celestial show of shows and our unique ability to understand it.

The Spring Peepining

The Spring Peepining

By Elyse Dilks

Naturalist -- Warner Parks


Spring Peeper

As spring approaches, there are many signs to let us know that warmer months are about to come. The flowers begin to bloom, insects begin to buzz around, birds that migrated during the winter months start to return home, and all the creatures that hid away in their warm burrows and dens creep out. However, one of my favorite signs of spring is when you start to hear the evening calls of some peculiar creatures that we know dearly as the frogs and toads.

Cope's Gray Treefrog

Tennessee is home to 21 species of frogs and toads, though not all are heard or seen here at Warner Parks. Since January, I have been on edge, waiting and listening for the frogs to begin their wonderous tunes. However, the start of 2024 has already been a strange one when it comes to the weather here in Tennessee. From temperatures ranging as high as the 60s-70s to lows being in the 20s-30s, each week this winter has been different. We were even hit with freezing temperatures that resulted in much of Nashville being shut down due to the ice and snow. With the weather being so irregular, it becomes harder to predict what the wildlife will do. In terms of frogs, some are more resilient than others to the cold, but with such random weather and temperatures, it was a mystery as to when we would hear the early bird, or in this case, the early frog.

Chorus Frog

It was just yesterday, February 14th, that I heard my first frog calls of the new year while out walking on the Old Roadway near the Little Harpeth River. The calls sounded like a finger plucking or dragging against a comb. These calls are made by Chorus Frogs, which are often the first frog calls heard due to their resistance to the cool spring weather. I was overjoyed to hear their melodic cries as they called back and forth to one another, even adding in harmonies.

Although I have yet to hear them, other species to be listening for are the Spring Peepers’ peeps and American Toads soothing trills. Once spring has officially begun by mid-March, many other species will start to come out. By the end of spring in June, most species of frogs will have emerged, having either completed or are just starting their mating call rituals.

American Toad

I highly encourage you to go out to Warner Parks for an evening hike where there is a nearby water source. Take a stroll around Butler’s Field, the Old Roadway, or even stop by and sit at a shelter or picnic table at the Little Harpeth River or Willow Pond. From my own experience, going out and seeing the sun start to set where the luscious colors of the world seem to fade, there’s a comfort in knowing you are not alone as the loud “WAAAAH” of a nearby Fowler’s Toad fills the air.
