A walk yesterday in the late afternoon. Copper and I ran down Folkstone Drive, then ducked into the woods. It was cool and quiet there, and what struck me first was the filtered light. This is a second-growth forest, maybe third- or fourth (if that’s possible). The oaks are 70 to 80 feet or taller, and the birch and hickories and other trees in the canopy shade the smaller plants, give them a vaulted ceiling beneath which to grow.

I take off my sunglasses, hold them in my leash hand. The colors are even more intense now — the dark greens of the holly and the brilliant hues of the newly unfurled ferns. In places the woods are carpeted with ferns. It’s a fern forest floor.

I look more carefully at the delicate fronds, watch them as they wave slightly in the breeze. There is something satisfyingly primordial about ferns, something soothing in their longevity on this planet. They thrive in the indirect light.

As I think of writing about ferns today, Copper tugs at his leash. The ferns are the height of his sturdy little shoulders; he swishes through them when he ventures off the path.
