If you’ve walked around Nature Boardwalk at Lincoln Park Zoo recently you might have spotted a great blue heron fishing around the pond.

Our Little Green Friends

You might be one of the many folks who struggle with plant names. Most of us do! For the select few who can rattle off a full list of nomenclature, I suspect good, careful observation combined with a gentle affection for our photosynthetic friends really helps out. What follows are fun tidbits about the new flowers at Nature Boardwalk.

For such a cheery, bright summer bloomer, I have to admit this plant has an unfortunate name. I can’t shake the image of an accident-prone young girl.

Ready For Takeoff!

Black-crowned night herons are statuesque birds that look as though they are wearing black capes and hoods. They have piercing red eyes and long white plume feathers that trail off the nape of their necks.

They don’t begin their lives looking quite that majestic, however.

Eastern Cicada Killer Wasp

The other day, while I was walking around the boardwalk, I heard a loud buzzing and rustling sound coming from the prairie grasses. When I looked down, I immediately spotted the source. A long, slender wasp with reddish-tinted wings was dragging a huge cicada along the ground, furiously buzzing and working its wings as it went along.

To my surprise, the wasp began climbing one of the wooden stakes we are using to anchor the goose fencing (netting temporarily in place to keep Canada geese from eating our new plantings).

Differentiating Dragonflies and Damselflies

An astounding 16 species of dragonflies and damselflies have already been identified at Nature Boardwalk. To tell one of these species from the next, biologists use species identification keys to look for specific features.

The first step is figuring out whether an insect is a dragonfly or a damselfly. These two groups share a common biological heritage: both are suborders within the scientific order Odonta. They are similar in other ways as well. Both are carnivores, eating other insects. Both start their lives in the water as nymphs and then emerge as flying insects.

Giant Water Bug Nymphs

You wouldn’t know it by looking at this little green critter, but this tiny animal will grow up to become a giant water bug. Zoo biologists found this insect while doing invertebrate surveys at the pond at Nature Boardwalk. Just like dragonflies and damselflies, immature giant water bugs are called nymphs.

Giant water bugs make up a family of insects that are often found in ponds.

Dragonflies of All Stages

Today a few colleagues and I put on our boots and waded into the shallows of the pond at Nature Boardwalk to take samples of the invertebrates that are colonizing the habitat. We swished our finely meshed nets back and forth in the water to collect aquatic invertebrates and then quickly transferred everything we’d caught into a bucket for temporary holding.

Stocking Nature Boardwalk with Fish

The pond at Nature Boardwalk has more than 30,000 new residents today! This morning we stocked the pond with multiple native species of fish. Approximately 800 bluegill and 600 pumpkinseed were given a brand new home at the pond, along with an astounding 100 pounds of fathead minnows. The minnows are about an inch long at stocking, so you can imagine that 100 pounds is a lot of minnows. There are approximately 300 individuals per pound!

The fish all arrived on a pickup truck, eager to get out of their small tanks and into the big pond that awaited.

Preparing for Turtles at Nature Boardwalk

We want to welcome many different types of wildlife to the pond at Nature Boardwalk, a desire that’s reflected in the area’s design and landscaping. A specific group of animals we hope to welcome is turtles. We plan on bringing turtles to the pond in the future, and some may naturally find their way here as well.

Because turtles can’t regulate their own temperature like we can, basking sites are a very important habitat feature to welcome them. Basking sites are spots where turtles can use heat from the sun to regulate their temperatures.

Pasture Rose

Every once in a while you run across a plant you think everyone should be growing just because you like it so much. And if you’re up on natives, this makes the case for the pasture rose (Rosa carolina). I can only find one flaw, but I'll get to that.

I’m glad we used pasture rose at Nature Boardwalk. The large, shell pink, flowers are decidedly pretty and the customary, glossy dark green leaves are handsome as well.

Behind the Scenes at Nature Boardwalk

Everyone here is gearing up for the big opening of Nature Boardwalk at Lincoln Park Zoo on June 24, and the plants are getting ready too! Prairie grasses will be a prominent feature of the landscape, a process that will take some time as they develop their extensive root systems.

In some prairie plants, as much as 90 percent of the weight is underground. This extensive root structure protects the bulk of the plants beneath the soil, enabling them to survive in an ecosystem with frequent disturbances, such as fire and drought.
