Sorry to have been away from this blog for so long; check back weekly from here on for more  regular updates.  I sometimes forget the important presence of the Shiawassee and our natural world, but then something usually reminds me, sometimes sharply, of where I live.   I was walking along the banks of the River the other morning lost in a reverie of thoughts not related to my surroundings when I came up short. There, right beside the trail, an ancient reptile was digging in and gave me a wary look.
 
Snapping turtles (chelydra serpentina) reside with some frequency in  the Shiawassee River, though their secretive ways keep us from seeing them often.  It’s dark color and rough shell, which is often algae covered, also camouflage its appearance.  Once, when wrangling a canoe through some shallow waters north of Owosso I almost stepped on a big snapper that looked just like one of the surrounding rocks.
 
The snapper I saw in Harmon Patridge (aka Green Meadows) Park had left the river to lay her eggs in the soft soil about 10 feet from the River.  Females lay their eggs in late May through early June, though she may have mated much earlier; female turtles remain fertile for years at a time, and reproduce only when they feel conditions right.  She would have layed between 10 and 96 eggs which will hatch later this summer or fall.  Because of heavy predation of the eggs and young, only a few new turtles will result from the hard work I saw this mom undertake to pull herself out of the river and dig out a nest.
 
Snappers have an undeserved reputation as vicious predators, and while they are omnivorous eaters in the aquatic ecosystem of everything from plants to leeches to baby ducks, they do not negatively effect gamefish populations.   While they do have a sharp beak and powerful jaws, they usually are only aggressive when attacked or out of the water.  As with most animals, its best to observe snappers from a distance.    You can learn more about this resident of the Shiawassee from the MSU Natural History Museum website (click here).
 
Snapping turtles live for 30 to 40 years, and as you can see from the photo, this one appears to have been around a while, having suffered but survived some trauma that cracked its shell.   This mother snapper reminds me that it’s not just the people in Chesaning who live downstream from us.  We share the River with lots of fauna, including chelydra serpentina.  What we do the River and the land around it impacts their life, for good or ill.
