Spiny softshell turtle. If you click on the photo to enlarge it, you might barely be able to see the little projections from the center of his nose that distinguish spiny softshells from smooth softshells.

Meet Henry.  Henry is a very small softshell turtle that spent a few days at our house in late August, 2010.  I’m not sure what Henry thought of the ordeal, but our family sure enjoyed having him.  He even went to school one day.

I found Henry along the Platte River and brought him home so my family and I could learn more about softshells – and I could get some photos.  Those of you who have followed this blog for a while will remember how I photograph small creatures like this (if you don’t remember, you can read about it here.)  Henry’s visit turned out to be a big success, at least from our standpoint, and we delivered him safely back to where I’d found him a few days later.

Spiny softshells are very good at burying themselves in sediment.

One of the things we learned was that softshells are very good at burying themselves in the sand – and they can do it amazingly quickly.  We’d be watching Henry walk along or sit and look at us, and then within about 5 seconds, he’d be gone.  It was really hard to tell how he did it – it was like he just slid into the wet sand.

Here, Henry shows off the length of his neck.

According to Dan Fogell’s excellent new field guide to the Amphibians and Reptiles of Nebraska, Henry really is a “Henry” – not a “Henrietta” because of the distinct spots on his back.  My kids, who named him (clearly) are relieved to know that.  Softshells have a smooth leathery carapace without the hard plates that are characteristic of most other turtles.  According to Fogell, they eat mainly small invertebrates, but will also scavenge on dead fish and even eat vegetable matter at times.  During  his short stay with us, Henry didn’t eat any of the offerings from my kids.

Although I’m not a big fan of people taking animals out of nature, I do think there can be great value in employing them as ambassadors in certain circumstances.  I hope Henry recovered from his time with us, and is living a normal life in the river now.  My kids will certainly never forget the experience, and still talk about Henry fairly often.  Whenever we go to the river, we keep our eyes out for him – and his colleagues – and it’s hard to wonder how many softshells are watching us from their submerged hiding places as we walk around.  Because they were able to form a “relationship” with one of the inhabitants of the river, my kids now see that river differently.  Rather than water flowing through sand, it’s a place where creatures like Henry live.  From a conservation standpoint, that’s a pretty important distinction that I’d like everyone to make.

Thanks Henry.

Photo of the Week – January 12, 2012

It’s been a very mild winter in Nebraska.  We took advantage of the warm weather on Tuesday to burn a small island in the middle of a stream/wetland restoration project area.  The day was sunny, and it was 55 degrees F with light winds when we started the fire.  (Quite a contrast with Wednesday, which was in the 30’s with winds gusting to 40 mph.)

Fire backs into the wind through a grove of young sandbar willow trees. The fire will top kill the trees, but they will resprout again in the spring.

The objectives for the fire included clearing most of the vegetation from the island to create feeding and roosting habitat for migratory cranes, shorebirds, and other species in the early spring.  We also wanted to burn through the willow trees that were establishing on the island and set them back before they started to crowd out the grasses, sedges, and other herbaceous wetland plants beneath them.  The fire worked out just right, removing most, but not all, of the vegetation.

It’s not often we can get a burn done in January.  Even when it’s warm enough, the days are too short.  By the time the day warms up enough to dry out the grass and support good fire behavior, it’s usually after lunch – and by mid-afternoon, the sun has dropped low enough that fire stops burning well and smoke stops lifting.  Most of our burn units are big enough that it’s difficult to complete them during that short window of time.  The island we burned this week, however, was less than an acre in size and we didn’t have to do anything but light it and let it go.  A great way to do prescribed fire!

The island was surrounded by a wide swath of water and sand, making it very easy to control the fire (which is why I had time to take photographs!).

The prairie cordgrass (Spartina pectinata) on the island burned very intensely, but other areas had standing water or other vegetation types that burned less well - leaving a mosaic of burned and unburned vegetation when the fire was over.
