Wetlands, Conservation and Waterfowl

Wetlands-
as vital to our ecosystems' health as kidneys are to a human's. You may not dwell on their importance, until they are compromised or cease to function.

The keynote speaker at OOS/Columbus Audubon's excellent Waterfowl Symposium illuminated the point with a photo presentation on the century's worst man-made ecological disaster. Quite a claim to fame, achieved by the one and only Saddam Hussein of Iraq.


Dr Alwash has been involved in engineering the re-flooding of the southern Iraq marshes, the cradle of mankind and the likely location of Eden. The marsh people of Iraq have thrived here for centuries, co-existing with the land and utilizing the marsh reeds for most of their needs, from fuel to building supplies, until Saddam intentionally left them high and dry. In order to punish the marsh people for rebelling against his power, Saddam drained the marshes- destroying their lives and livelihood.
Today efforts are being made to reintroduce water to this region, once again allowing the marsh reeds to grow and thrive. For the full story, you can go to National Geographic on line and read Iraq's Eden: Reviving the Legendary Marshes.

And while Americans tend to dismiss all reed grasses as undesirable invasives, even the worst of these harbor an abundance of species, from insects, to frogs and birds. And with proper management some very desirable diversity will thrive along the edges of these areas, i.e. Cleveland Museum's Wakerobin Trail.

If you are interested in learning more about wetlands diversity be certain to follow this link to the FOWL organizations link where you will find a registration for an upcoming Managing Wetlands for Biodiversity. Greg Lipps will cover the fauna, while Dr Jim Bissell and John Mack will handily address the flora.
...
And while you are thinking about wetland conservation... don't forget to purchase your Federal Migratory Bird Hunting and Conservation Stamp to help purchase wetlands. They are not just for "Ducks!" And to support biodiversity in Ohio, look for this Ohio Wildlife Legacy Stamp. We will be selling them on the upcoming GMAS trip to Killdeer Plains. So click on our website for details, and plan to meet us there March 6th, 2010. Hope to see you there!

Return of Jaret Daniels

So who is this Jaret Daniels, and where is he returning? If you are an Ohio Butterfly enthusiast, you'll already know that name. Jaret is the author of Butterflies of Ohio, an amazing little book that covers all the colorful butterfly species found flying in the buckeye state.


The most common, the Spring Azure, a delicate blue beauty (magnified here to 4 times its actual size!) found near woodlots and dappled shade is a fast flier who rarely provides an extended look.

Equally appealing are Red-banded Hairstreaks, just one of our many, similar-looking, gossamer winged hairstreaks. They can be a challenge to sort, but how gratifying would it be to find a rare White-M Hairstreak! It would be the same thrill a birder feels when finding a Mississippi Kite or a Kirtland's Warbler, all three are rarities in Ohio.

If you don't have this book, you'll want to go here and order one.
Butterflies are interesting creatures of diverse habits and habitats. Most are highly selective, with specific host plants needed to maintain their larva. There is such an intimate tie between butterflies and their host plants, it is not surprising that Dr. Jaret Daniels is a botany guy too.
What is surprising, is the fact he would trek all the way from Florida for the third year in a row- just to see the Southern Ohio butterflies and lead a Flora-Quest trip!


So if your wildest dreams include Olive (Juniper) Hairstreaks, or...



the subtle shades of Henry's Elfins, you'll want to beat feet to the Flora-Quest website and download a registration form. You'll have to write in "BUTTERFLY TRIP" as this news is so new- we don't even have it listed yet!
Everyone attending Flora-Quest will get a species list of the butterflies found in Shawnee during the spring, and I hope you'll enjoy these little beasties as much as I do.
Maybe some year we will have to offer a "Caterpillar Quest" too!

X-Country Nirvana

Making the most of our snowy days, I ventured out this morning to try a bit of real cross-country skiing. Surrounded by corn fields and woodlots in mid-Ohio, this is as "cross-country" as it gets. The ice-enhanced snow created the perfect platform to cross acres of plowed fields, usually damp, deep furrowed and difficult to trod .


The temperatures had crept up to the mid 30's, but the snow remained crusted over with a layer of ice, caused by several days of thaw and re-freeze. It was a skier's nirvana which fully supported my weight, spread out on 6 foot of ski surface, above a foot or so of snow. However, the snow conditions quickly became a burden for the beast.


Argus, the butterfly hound, was having a tough go of it. With each step into the snow, he sunk elbow-to-shoulder deep, bringing all progress to a whimpering stand-still.


Fortunately a snowmobile track provided just the right amount of compaction to make mobility possible. He was limited to following the track marks across the fields, but at least he was able to follow along.
This photo reminds me: if you are not the lead dog, the scenery never changes. Argus is definitely the lead dog.

The fresh air and sunshine was only enhanced by the calls of the Horned Larks as they scattered throughout the fields. Flocks of these yellow-faced bandit birds spend the best part of winter gathered along the road edges, seeking out cast-off seed (and perhaps salt?) Generally difficult to view in close range, the flocks lift off in a twisting flight, leaving behind only their soft "twinkling"calls.


Great Blue Heron, Wood Duck, Woodcock- it is always a treat to see what creatures are utilising the creek at our property's edge. Last winter, I witnessed a Bald Eagle cruising through at top speed, lifting an early evening opossum right out of his tracks! Yum-yum. 'Possum, the other white-meat.
Today is was an American Pipit that provided the surprise for our journey. Once called the Water Pipit, these birds are known to work water edges for seed and insects during their migrations. A wagging tail and self-declaration of "pi-pit" were dead giveaways to its identity as it provided the closest looks I have ever seen. Let the migration begin!

Mega-fruit for Megafauna?

Did you ever wonder what birding has to do with a Flora-blog? Or how birding might improve one's understanding of botany?


The answers became clear to me this week. As a Weedpicker, I am always curious about the relationship between plants and animals. And while enjoying good looks at Green Lawn Cemetery's Merlin (Jim McCormac has that story), I started asking questions about trees.

In particular, the fruit of the Kentucky Coffee Tree, Gymnocladus dioicus has always intrigued me. It is so large, and heavily armored... what could possible eat it? Certainly, no birds have bills adapted for the task.



.................Photo by Bruce Marlin credit Wiki


Or the fruit of the Osage Orange, Maclura pomifera- what utilizes this large fruit? Is its seed only distributed by rolling downhill and floating along creeks? Or by the ballistic practises of 10 year old boys?


A fascinating article addressing these questions appeared in AmericanForest.org. Whit Bronaugh's article Trees that Miss the Mammoths make a compelling case for the mega-fauna being the primary seed dispersal for these two plants in particular, and others as well.


No wonder it did not add up in my brain, it has been a while since we've seen giant ground-sloths in my neighborhood, but by evolutionary standards- the 13,000 years since they became extinct is much like last Tuesday. The trees are just now starting to take notice, and may have to adapt to new seed dispersal strategies or die out. And that my friend, is the stuff of Mendel and Darwin.

Dramatic Dragonflies

Since I've been in the mood for dragonflies, John Howard sent me some of his best finds from 2009. I've been drooling over this file of incredible dragonflies, each one is better than the next... and hopefully, you'll enjoy them too!

Blue Corporal - this one was found in Adams County- is a real rarity in the rest of the state. It was big news when several of these were found a year or so ago.


Black-shouldered Spinyleg- is an impressive beast. It may only measure in at 2" but it looks mighty serious with those jagged spines on the hind legs. I have never seen this "uncommon" dragonfly, but John's photo of one perched on Ironweed, Vernonia sp. makes a picture suitable for framing.


Can these eyes be mistaken for anything but an Emerald? It is a Clamp-tipped Emerald, in fact. Again, an uncommon species in Ohio, named for the male's obvious-looking cerci (these are for some serious business with the lady clamp-tails.)


An utterly gorgeous photo of Slaty Skimmer, probably not as rare as most of the others shown here, but this photo was so beautiful, it simply begged to be shown. And it is a good one to be familiar with, as it is very similar to the much rarer Spangled Skimmer (which would have a speck of white along with the black dot on the wing stigma.)
Have patience and learn one or two at a time, and they are not as confusing as they first seem. Dragonflies can be sorted by habitats and behaviors as well as color. Be aware that dragons are often sexually dimorphic and the males and females can vary greatly. It only adds to the adventure!

Again, special thanks to John Howard for allowing me to share these wonderful photos. If you ever want a real challenge, try to photograph some dragonflies!
