Coming from the perspective of a human (a true biological juggernaut of adaptability), the past couple of weeks have been a real joy. For a few glorious days, I wore a tank top outside at work (in February!) and today I’m walking in a winter wonderland again. While the particular weather pattern we’ve just experienced here in Milwaukee has been a treat for us humans, for the plants around us, trees and shrubs especially, it will prove to be more of a trial.
For those of you who may not know, we have an organization-wide phenology competition every year to document the first of year (FoY) Red-winged Blackbird, Eastern Chipmunk, Mourning Cloak, and Butler's Gartersnake. The documentation of these four species typically signifies the arrival of spring and the dismissal of winter. This year's unseasonal warm weather, however, has a resulted in an uncomfortably early kickoff.
It is the season of showy butterflies, buzzing cicadas, crackling grass hopper wings and CRIKT research. Nope, that is not a typo. CRIKT stands for “Citizens Researching Invertebrate Kritters Together” and this research team at the Urban Ecology Center is leading the nation in its approach to field ecological research. “Invertebrate Kritters” refers to the vast array of animals found in the insect, spider and mite categories. Because invertebrates impact people in a variety of ways: pollinating crops, decimating crops and invoking some of our greatest fears or senses of awe, they have been studied quite a bit over the years. So what sets CRIKT apart? It is WHO is involved and WHERE they work.
A potent odor in Three Bridges Park recently led us to a dead skunk lying next to the Menomonee River. It rested, amazingly intact, on a sewerage outflow pipe lightly covered in snow. Whether he was the victim of hypothermia, winter starvation or a ravenous hawk remained a mystery, but whatever the skunk’s demise, it was clear that two weeks after he had perished, his scent still lingered.
Last fall at Riverside Park, the research and citizen science department was hosting the Wisconsin DNR’s bat biologists for an evening of bat mist netting, when a gregarious little screech owl paid us a visit. As DNR biologist Paul White held the large group of participants enraptured with a live bat, a persistent whinny in the distance distracted those of us at the back of the group.
When I think of the opossum, I think of a scrappy little character; tough, resilient, clever, and tenacious. In fact, one of my first memories of the opossum demonstrates its impressive adaptability. When tree hollows and brush piles provided inadequate shelter, the resourceful opossum sought shelter elsewhere - she would sneak in under our house's raised foundation and hunker down next to the hot water pipes beneath the bathrooms. There, she would build a comfortable bed of dry grass and stay till spring. And sometimes, when my family would take a shower or bath, you could even hear the scratching of little opossum paws against the water pipes, presumably acknowledging the relief provided by the warm plumbing.
By now you have probably heard about the Riverside Park Beaver. He’s been chewing down Milwaukee River Greenway trees since the summer of 2014, has been featured on local news segments, has been written about in social media and blog articles, and even became the star of our recent Earth Month grant-matching campaign. But, how much do you really know about this busy beaver? You might be surprised to learn that this species is much more complex than one might think.
Thank you to everyone who helped make the 5th Annual Green Birding Challenge a success! 19 teams, comprised of both experienced and fledgling birders, participated in this year's challenge and observed over 100 distinct bird species in a fossil fuel free search around the city. Their efforts inspried more than 150 generous donors to pledge $8,000 for the Center's Citzien Science program. Wow! Read on for more fun facts and photos from the day's birding adventure!
I have a confession. A part of me enjoyed when the Riverside Park beaver was a secret. I liked sneaking through the park examining tree trunks along the river for signs of beaver chewing. I enjoyed watching the progress of the chew on the large cottonwood that first revealed signs of the beaver. I enjoyed sharing the location of the tree with nature-loving volunteers and I entertained myself by photographing two of those volunteers with the last name "Beaver" kneeling next to the tree pretending to gnaw at the bark.
Our research program has two unique features: an urban habitat focus and the inclusion of volunteer citizen scientists.
The urban wilderness research and monitoring we do provides baseline data that allow us to track how our habitat improvements affect wildlife over time. We’re measuring the changes so others can replicate the results in other cities.
We are one of the leaders of an international movement to facilitate community-led research and monitoring. Our Citizen Science program focuses as much on the process of engaging community volunteers as it does on the research process itself. What this means is that everyone can contribute in a meaningful way to scientific research.
