Karen’s Wetland Videos

One of my favorite places within our Platte River Prairies is a restored wetland we usually call “the sandpit wetland” because it is a former sand and gravel mining pit.  We restored the site over about 10 years, a little at a time, and it now features a meandering stream and various side channel, backwater, and off-channel pockets.  You might remember the site from previous posts, including this one about sludge and this one (or this one) about timelapse imagery.

I always enjoy walking around the wetland – even if I’m fighting off invasive species – because there’s so much to see.  I have a pretty good feel for the plant community at the site because it’s easy to find the plants and watch their slow movements around the wetland over time.  There are more invertebrate species than I’ll ever be able to count, of course, let alone see, but I can usually find quite a few of them if I look.  However, it’s harder to see and keep track of the larger animals – the birds, reptiles, amphibians and mammals.  For some reason, they don’t usually show themselves when I’m there…  (Especially the otters…. don’t get me started.)

Our timelapse imagery over the last couple years has helped us keep track of some of the wildlife use at the site, but since those cameras only take photos at regular hourly intervals, catching animals in front of the camera is just a happy accident.  Now, however, one of our longest tenured volunteers, Karen Hamburger, has taken it upon herself to find out what’s really out there.  During the last year or so, she’s been setting a trail camera (actually more than one, since at least one was inundated in a flood) in various places around the wetland and capturing views of many wildlife species.

I finally had a chance to go through some of her favorite video clips the other day, and I made a short 3 minute video montage with some of them.  It includes several bird species, beavers, deer, raccoons, and even (sigh) otters.  We knew from tracks and other sign that most of these animals were around, but it’s one thing to see footprints and another to watch the critters themselves!  This video gives us a wonderful and unique perspective on what happens at our wetland when we noisy blundering people aren’t around.

I hope you enjoy it.

 

THANK YOU to Karen for all the work to capture these moments for us, along with all the other work she’s done over the years!

Who could be mad at these big beautiful brown eyes?

As it turns out, lots of people can.

The differential grasshopper is one of a long list of native North American species, headlined by white-tailed deer and raccoons, that have adapted very well to today’s agricultural landscapes.  Whether you call these species adaptable generalists or pests probably depends upon whether or not they’re eating your sweet corn.  Regardless, you have to admire (or at least recognize) the traits that allowed them to thrive under changing habitat conditions that have pushed many other native species to the brink of extinction.

The olive-greenish color and the strong herringbone pattern on its back leg helps distinguish the differential grasshopper from other species.

Peek-a-boo!

Peek-a-boo!  Isn’t she cute?

Before Europeans took over the continent, differential grasshoppers lived mainly in low grasslands, feeding on a wide variety of grasses and wildflowers – but, purportedly, with a particular affinity for giant ragweed.  When the landscape began changing to one dominated by rowcrops, alfalfa, and short-grazed grasslands, it basically created heaven on earth for differential grasshoppers.  Today, they are abundant enough that they can be found almost anywhere across the landscape (at least in Nebraska).  Apparently, they can move as much as 10 miles a day to find food.

One of 108 grasshopper species recognized as native to Nebraska, the differential grasshopper is one of only a small handful that actually cause any economic damage to crops.  All of those grasshopper species – pests or not – are important food sources for birds and many other wildlife species.  In years when differential grasshopper populations are particularly high, they can cause more problems for farmers and gardeners, but also provide even more food for wildlife.

“Don’t hate me because I’m beautiful.”

It’s ironic that many traits we admire in people (resilient, adaptable, successful) become indicators of pest-ness when we’re talking about wildlife.  Really, we should give differential grasshoppers some kind of award for their ability to take lemons and make lemonade (that’s just a metaphor, kids).  Hooray for differential grasshoppers!

Unless, of course, they’re eating your sweet corn.
