Amphibians!

Typically, March is not my favorite month. Dreary, cold and windy describe most Marches in central Ohio, making an out-of-town Spring Break sound quite appealing. This year, although there were some dreary, cold and windy days, March had many warm days and even some warm nights. Warm nights plus a bit of rain in the early spring trigger an astounding amphibian mating frenzy that can extend into April. Many of these animals, which are generally quite hidden during most of the year, find their way to ephemeral ponds called vernal pools, and do their best to perpetuate their species. 

Why gather in vernal pools? These shallow water bodies dry up rapidly in summer and do not seem to be hospitable places to lay eggs that need to undergo complex metamorphosis in order to become adults. They have one big thing going for them though--no fish! Fish would relish eating the frog and salamander larvae in the vernal pools. The amphibians deposit vast quantities of eggs in the pools, and while some may be lost if the pool dries too quickly, overall reproduction is more successful than it would be if there were fish to contend with.

We've had several early spring adventures in central Ohio that featured vocal frogs that were out and about calling for mates. One of most common (and largest) is the wood frog:

Here is a brief video that illustrates the barking sound of this amphibian:

At another vernal pool a cacophony of chorus frogs greeted us, sounding like someone is scraping a fingernail across a comb:

We were lucky enough to get a view of a chorus frog:

We recently heard some chorus frogs calling from a large puddle near a parking area in Scioto County. I walked over to the puddle and was partially hidden from view by some construction debris so this little frog kept right on singing:

Here he is, belting out his message:

After mating, western chorus frogs will be hidden in the mud and leaf litter most of the year. We were quite fortunate to see them! 

A spring peeper is tiny, only about 2 inches in length, but makes a huge sound. This photo illustrates the typical "X" mark on its back:

Although they are quiet, many salamanders also gather in large numbers in early spring in the moist forest and in the vernal pools. Here are a few that we were fortunate enough to spot this year, hiding under logs in the wet woods.

The redback salamander is one of our most common, and it often hides under fallen logs anywhere in the moist forest:

The redback is one of the few salamanders that lives entirely on land and generally does not go into the water, even to breed. 

Although they can be found in a variety of habitats, we don't see many smallmouth salamanders, but enjoyed seeing this one:

The spotted salamander is always fun to find. They are fairly common but seldom seen except in early spring:

Despite the fact that most people are totally unaware of them, all of the animals featured in this post are locally present in large numbers in our forests and are important components of healthy ecosystems. Unfortunately, their numbers are declining in many parts of their ranges due to habitat loss and other factors. Their fascinating life cycles and utilization of the vernal pool habitat makes them well worth our attention. These critters made our March and early April much more fun and interesting than I anticipated!

Butterflies Have Re-appeared!

Last summer we had a lot of fun discovering Ohio's butterflies, so we were looking forward to seeing early species emerge this spring. Different butterfly species have different ways of coping with winter. Some can't live through our winters at all, and have to re-colonize our area from the south. Some overwinter here as eggs, some as caterpillars, and some as adults. Those that spend the cold months as adults tend to be among the first to emerge in the spring, ready to take advantage of warmer weather. 

Last week we hiked the wonderful Miller Sanctuary State Nature Preserve near Bainbridge. It was a lovely warm day and as we ambled down the trail I noticed a flash of orange that landed on a tree trunk. A closer look revealed it to be an Eastern Comma, one of the butterflies that overwinters as an adult while protected in a crevice or under some loose bark. 

As we got closer, I noticed some odd markings at the base of the tree:

After a moment I understood what I was looking at. A beaver had chewed the bark off parts of the trunk, and the tree reacted by exuding sap. Insects arrived to feed on the sweet liquid, including several more commas and a lot of flies:

I had certainly never thought about this particular interaction among trees, insects and mammals!

Miller is a great place to view spring wildflowers, and in a few weeks it will have impressive displays of Virginia bluebells, large-flowered trillium, and many others. Although we were too early for most of the flowers, we spotted a few early bloomers, including hepatica,

the tiny harbinger-of-spring

and snow trillium.

Spring is just beginning--we have many more wildflowers, butterflies and hikes to look forward to!

Exploring the trails at Old Man's Cave

I mentioned in my last post that we recently visited the Old Man's Cave area of Hocking Hills State Park. This is arguably the most scenic attraction in all of Ohio, and it is accessed by a network of trails that features tunnels, stairways, bridges and narrow pathways. We have lived in Central Ohio for 30 years, yet until this year we had only been there once before quite long ago. I think we avoided the area for several reasons--the trails can be quite crowded, it isn't a very good area for seeing birds (our main hiking priority for many years), and wildflowers are scarce in the surrounding hemlock forest. We rediscovered it this winter and found this magnificent gorge to be well worth our attention. In fact, we have hiked the area twice in the past 2 weeks.

We began the trail above the upper falls, where a series of cascades barely hints at what hikers will see in the gorge:

The upper falls are beautiful right now; later in the year the area will be nearly dry:

The trail through the gorge leads by steep cliffs that were covered with icicles on our first visit:

We encountered several bridges as we made our way down the stream:

This one was covered with ice and quite treacherous on our first visit last week:

The sandstone bedrock has been sculpted over time into cliffs, caves, and this nearly circular formation:

Named for a hermit that lived in the area in the early 1800s, Old Man's Cave is a deep recess in a magnificent sandstone cliff:

The cave isn't easy to photograph but here is another view:

The trail system gives access to many interesting rock formations and small waterfalls:

I loved the blue-green pool at the base of the lower falls:

The trail continues about 3 miles down the gorge to beautiful Cedar Falls:

Very little sunlight reaches the floor of the gorge so we didn't see even a hint of a spring wildflower there. Along the rim, though, coltsfoot was just starting to bloom and added a welcome spot of color:

The Old Man's Cave area is extremely popular and can get crowded at certain times. The scenery is fantastic, though, and I'm glad we have rediscovered it!

Central Ohio Waterfalls

This winter we have stayed pretty close to home, in contrast to 2015 when we were frequently out of town. We have enjoyed this relatively mild winter at home more than I expected, largely thanks to the fact that we have gotten out to explore various natural areas nearly every day. Since there has been plenty of precipitation, we have made a point of visiting several waterfalls within about an hour drive, most of which we had never seen prior to this winter.

One cold day in January we headed west to Greenville Falls, which is part of the Miami County Park District:

Another view of the falls shows the ice formations along the sides of the stream:

From there we headed to nearby Ludlow Falls, a pretty good drop considering the generally flat topography in this part of Ohio :

My favorite waterfall that day was West Milton Cascades, tucked into a ravine right in the small town of West Milton:

Here is another view, from the icy steps that were constructed long ago to give access to the falls:

Hayden Run Falls is about 5 minutes from our house, and I had only been there once many summers ago when just a trickle of water fell over the ledge. That visit involved a messy scramble down a steep cliff, but several years ago the City of Columbus parks department built a stairway and boardwalk to give safe access to the falls. The contrast between our January visit and my long ago trek was quite dramatic!

A few weeks after that photo was taken, we stopped back by Hayden Run after much of the ice had melted:

What a difference a few days of warm weather makes!

On another one of the warmer days this winter, we headed to Knox County to 25-foot tall Honey Run Falls: 

We had never been there before, and enjoyed the hemlock forest, impressive sandstone boulders and a short trail that leads from the falls to the Kokosing River.

Another interesting waterfall that neither of us had ever been to is Indian Run Falls in Dublin:

Located in a steep ravine behind the Dublin Library, Indian Run is rather hard to photograph but is well worth a visit. The City of Dublin has constructed a series of stairs and trails to allow safe access to several viewpoints.

One weekend we headed west to Charleston Falls Preserve in Miami County. This park has an extensive trail network in addition to the waterfall, which is the main attraction. The bottom of the falls is accessible via a series of stairs and a boardwalk, which were quite icy the day we visited. I actually preferred the view from above, with the falls flanked by a stately sycamore and a tall cedar.

Last week we topped off our series of waterfall visits with a trip south to Hocking Hills State Park. My favorite was this view of the upper falls at Old Man's Cave:

Just above the falls is a series of scenic cascades:

Here is a photo of the lower falls at Old Man's Cave. 

The entire hiking experience at Old Man's Cave is great (if it isn't too crowded) and I highly recommend it. 

Cedar Falls was flowing quite well; I liked the way the water splits over the rock and comes together again:

Our last waterfall in this series is at Ash Cave, another part of Hocking Hills State Park. It didn't have a lot of water, but the setting is so impressive:

A trail leads behind the falls to another view which includes the massive recess cave for which the area is named:

All in all, we have managed to enjoy this winter here in Columbus (much to my surprise!) and our waterfall expeditions have been some of the highlights. If you would like to see more pictures of some of these falls, check out Jim McCormac's excellent blog here.

Early Spring At Inniswood

At the end of February we were were hungry for some signs of spring so we headed over to Inniswood Metro Gardens in Westerville. We first walked around the woodland trail, which still looked quite wintery:

The young beech trees tend to retain their leaves all winter. The reason for this is not known for sure but there are several theories as to why young beeches and some oaks don't completely shed their leaves in the fall. In a month some nice spring wildflowers will be blooming in this beech-maple woodland. 

Unfortunately, evidence of the devastating damage done by the emerald ash borer was obvious along the trail:

This invasive insect has killed literally billions of ash trees in the midwest. Its larva feeds on living tissue just under the bark, destroying the vital channels that deliver water and nutrients to the tree.

We took a delightful walk through the rest of the grounds, promising each other that we would visit more frequently than we have in the past to see the garden's sequence of blooms throughout the summer. There was plenty to see in late February, though. Here is a nice hedge of winterberry holly, a deciduous shrub that retains the brilliant red berries all winter:

We were delighted to see many crocuses in bloom. They must have been planted many years ago because in some places they have naturalized into the lawn and down wooded slopes:

A large bed of winter aconite was also a welcome sight:

Looking closer, we saw some very active bees visiting the flowers. (None of the flowers pictured in this post are native, but they are early, colorful and attractive to honeybees, which are also non-native.)

The snowdrops were in full bloom too:

The children's garden is one of my favorite places at Inniswood. These enormous sunflowers welcome visitors:

In the farmhouse replica in the background are whimsical murals that I always enjoy:

As the temperature warms, the delightful sounds of real frogs will fill the air near Inniswood's wetlands. 

My kids would have had a hard time leaving this treehouse and swinging bridge:

As we left the gardens we found some Lenten roses (hellebores) just beginning to bloom:

The action is just beginning at Inniswood and we definitely are looking forward to seeing what comes next!
