“Humankind has not woven the web of life. We are but one thread within it. Whatever we do to the web, we do to ourselves. All things are bound together … all things connect.” — attributed to Chief Seattle
I’m an environmental educator. Have been one all my life. Among my goals? To erase the line between us and the environment. So often we think of nature as someplace we have to travel to. But this separates us from understanding how we affect our world — for good or for bad.
Amazing creatures like this robber fly can be found in your backyard. These excellent predators catch their prey in the air.
At this time of year we are surrounded by appeals to plant trees. Conserve water. Recycle. Save the polar bears. Want to find examples of IPM as an Earth Day theme? Good luck.
Which is too bad. Because the critters and plants that surround us prove that the environment is right here, right now, all the time. The mice in your kitchen are proof that we coexist with nature even inside.
There is no line.
What’s in a name? Is this a weed or a spontaneous lawn flower? The bee doesn’t care!
Basic ecology tells us that all living things need food, water, shelter, and space. Overwater an indoor plant and you will find fungus gnats. Mow your lawn too short and spontaneous lawn flowers will outcompete the grass. Fail to empty outdoor buckets or refresh the water in your birdbath and there will be no shortage of mosquitoes.
When living things move into our space, we typically label them as pests. But this, my friends, is how nature works. When we provide food by leaving dirty dishes around, don’t seal the garbage right, or plant a favorite flower (tulips, say) in an area with no shortage of deer, we might as well just sit back and watch what comes to partake of our offerings.
Who needs to visit Africa? We can watch the circle of life in our backyards! And no need to get all those shots!
I dream of a world where, along with learning about tigers and redwood trees, children learn about our environment through ants and dandelions. For even in the most urban areas, we find ourselves in nature if we only open our eyes and take the time to recognize it.
My appeal? For Earth Day 2017, let’s each learn about one critter we see often – especially one we consider a pest. Where does it fit in the food web? What helping hand have we given it? And to help your exploration, I recommend starting with the NYS IPM Program’s What’s Bugging You webpage.
Erase the line. And have a very happy Earth Day.

by Mary M. Woodsen Comments Off on Earth Day IPM for birds and bees — and native plants that nourish them
We’re starting this post with a detour. But we have little choice. Before you go shopping around for landscape plants, you need to know the backstory.
Invasive plants, trees, shrubs, vines and flowers, many of them brought from afar because yes, they’re lovely in the landscape, have become a bit too much of a good thing. In part it’s because they didn’t evolve here. That could mean the critters — mostly insects or pathogens that co-evolved with them and helped keep them in check — don’t live here. Where that’s the case, there’s little here to naturally keep them in check.

True, not all imported plants are invasive. But it’s all too easy to dig up a seedling or sucker from an invasive when you don’t know the extent of the problem. Which is partly why New York passed the Invasive Species Prevention Act in 2012.
Native plants, on the other hand, are less likely to get out of hand. Plus they can encourage biological control by attracting predatory or parasitoid insects — the good guys that prey on insect pests. And promoting these good guys is key to good IPM.
So with Earth Day in mind and planting season at hand, let’s note this threesome of invasive trees: angelica tree, sycamore maple, and Amur cork tree. These landscape trees are no longer for sale in New York. For a threesome of attractive natives that can fill their place — while helping the birds and bees — consider the merits of (drum roll) staghorn sumac, Juneberry, and white fringetree.
As we speak, migrating birds are stripping last year’s crop of staghorn sumac seeds, now mostly dry and withered but still nourishing, to power their northbound flight. Love birds? Your sumac planting will benefit robins, bluebirds, thrushes, catbirds, cardinals, chickadees, starlings, wild turkey, pileated woodpecker — and that’s just for starters. Soon its tiny yellowish flowers will attract bees and butterflies. Fiery autumn color. Drought resistant, and an excellent soil stabilizer on hillsides.
Juneberry isn’t your traditional hummingbird plant but welcoming even so. And first to flower means first to fruit — nourishment for many nesting songbirds. (Photo credit Hans. Thank you, Pixabay)
Juneberry (Amelanchier spp., with more common names than you can shake a stick at) is also an early bloomer that draws hummingbirds, bees, and butterflies. When its fruits ripen in early summer, robins, waxwings, cardinals, vireos, tanagers, and grosbeaks make a point of stopping by for a meal. You might too — the subtle flavor, shape, and color are reminiscent of blueberries. Grows well in full sun or part shade; adapts to wet or dry soils — but note soil must be acidic.
And then — raise your hand if you’ve seen our native witch hazel. This late bloomer is (metaphorically, that is) the golden chrysanthemum of the woods, daring to blossom when other trees have tucked in for a long winter’s nap. How to describe its flowers? Ribbonlike. Spidery. Kinky. Confetti-like — these all serve for a tree that’s the only show in town. But … if pollinators have tucked in too, how to play the pollination game? Turns out a native moth, the sallows, comes out on chilly nights — shivering its flight muscles and raising its body temperature upward of 50 degrees, then flying off search of food. And during a warm spell, bees will sup here too. Yes, this tree benefits birds and wildlife too, but more on that another time.
Witch hazel makes a lovely understory tree. Prefers part shade and moist but well-drained soil.
Common to all? They fit neatly under power lines.
And now a plug for IPM: it’s easy to talk about the birds and bees. Yet so many critters are on our side. Understandably we shudder when wasps and flies come to mind. But consider the scads of wasp and fly species that are on our side. Hey, plenty of wasps don’t even have stingers; they care only to lay their eggs within pest insects. Flies? Ever heard of flower flies? They do what their names suggests, while their larvae prey on aphids and thrips. And there’s scores more good guys in the family they belong to.
By most measures it’s spring in the northern hemisphere. Technicalities count: regardless if you live in snowy Labrador City (pop. 9354; high of 15ºF) or greater Miami, Florida (pop. ~5.5 million and summery 76ºF), the vernal equinox marked the official start to spring.
Whether or not the weather concurs with your expectations, of course, depends on your point of view. (Here in New York, opinions are mixed.)

Our question to you — what does Earth Day mean for our homes and forests, our farms, lakes, and rivers? And how does IPM help?
