Nature blog: Tying up some loose ends on Heaven’s Hillside

This post originally appeared on April 15, 2012 on Nature Writing.

During my nature writing class at Chatham University’s MFA program, I had to keep a weekly nature blog. Each of us picked a place and spent thirty minutes in that place each week, and then wrote a blog post about it. I’ve just bought a house and moved away from this place, so I thought reposting these entries would be a good way to celebrate the time I’ve spent there. I’ll tag each one “natureblog2012.” This is the final entry.

As our early spring progresses, more and more plants pop up every day on the hillside. The robins are singing this morning, and there’s a slight breeze. The sound of a neighbor’s lawnmower drones on behind the birdsong, wiping out the sound of cars on the highway. It’s cool, but it’s the kind of cool that promises heat later in the day. The stinging nettle now completely blocks off the back half of the yard, and the Japanese honeysuckle is about to go into bloom. The rose of sharon shrubs have shed their seed pods entirely and unfurled leaves all up and down their gray-brown branches.

The black willow. You can also see the dead tree of heaven and a Boston ivy vine.

What I assumed was Japanese honeysuckle vines climbing the trees of heaven nearest my house are not. Now that the leaves on the vines have grown, I see that they are broad, flat, and triangular, nothing like the long, thin leaves of the honeysuckle. I think it’s Boston ivy, also known as Japanese ivy or Japanese creeper. Another invasive species introduced from Asia. Boston ivy got its nickname from its use in that city on the sides of brick buildings. By allowing the plant to climb the sides, it provides shade and reduces heating costs in the summer.

In looking closely at the tops of the two trees of heaven closest to the house to try to figure out what kind of vine was climbing them, it looks like one of them is actually dead. If it isn’t dead, at the very least, it’s dying. It doesn’t have any buds. I didn’t notice at first because its branches intertwine with a few other not-dead trees of heaven. It’s bark has fissures on it as well, which is a sign of age in trees of heaven. They only live about fifty years, so it’s not surprising. The one next to it is probably not much younger.

Boston ivy is growing along the right-hand fence, though there it appears to be much thicker and vibrant. The vines growing on the trees of heaven don’t seem very healthy, though, as not many leaves have grown from the vines. I wonder if this has anything to do with the chemical the tree of heaven releases to impede the growth of other plants. In addition to the Boston ivy, common ivy, the dark green ivy frequently seen covering the slopes in front of homes, also grows in my back yard. The stinging nettle and various other plants keep it in check. Before I moved to Pittsburgh, common ivy was the only type of ivy I’d ever seen.

After clicking through almost every tree on the PA Department of Conservation and Natural Resources online list of common trees of Pennsylvania, I finally deduced that the not-dead tree is a black willow. Its leaves hang down from the branches in long, graceful clusters. A chunk of the willow’s trunk hangs off, like a gaping wound, but otherwise it seems healthy. The wound doesn’t go deep, so I hope no insect invaders nor fungi find a way to take advantage.

A new bird song that I haven’t heard before picks up. Although it’s become harder to see birds in the foliage of the yard, they chase each other back and forth constantly. I catch flashes of movement, a wing, a tail. Even now my presence doesn’t bother them, when it did in the winter. They zip around, back and forth, back and forth. Today it’s the sparrows chasing each other, but I hear at least half a dozen species chirping and singing. I imagine it’s good to be a bird in the spring time.
