Tree of the Week



Green AshFrazinus pennsylvancia Marsh.

DISTINGUISHING CHARACTERISTICS: Leaves once-pinnately compound, opposite, 10 to 12 inches long; leaflets 5 to 9 in number (usually 7), oblong-lanceolate or less commonly elliptic, 2 to 6 inches long, tapering at the base and extending along the upper side of their 1/16- to 3/16-inch-long stalks; margins conspicuously toothed; upper surface dark green and often glossy; lower surface light green, glabrous or nearly so (hairy in the form called red ash). Winter twigs moderate in diameter, gray, glabrous (finely hairy in the form called red ash); leaf scars small, half-round to nearly round, bundle scars numerous and very close together, forming a fine curved line. Buds globose to subglobose, brown, with 1 or 2 pairs of visible scales, the terminal 1/8 to 1/4 inch long. Flowers very small, dioecious, apetalous, appearing with or before leaves; staminate in short, compact panicles, pistillate in open panicles. Fruit a narrow, paddle-shaped samara 1 to 2 inches long that often persists in winter; wing extending along upper half of seed cavity. Bark ashy gray or gray-brown, furrowed, with narrow, interconnecting ridges enclosing diamond-shaped spaces.

SIMILAR TREES: White ash has relatively broad leaflets with entire or obscurely tooth margins and stalks about 1/4 inch long; the wing of its samara does not extend along the sides of the seed cavity. Black ash has 9 to 11 unstalked leaflets and its fruits have indistinct, flattened seed cavities.

IOWA DISTRIBUTION: Native and planted throughout the state.

Gardening in October

Wednesday, October 11

Today the weather's so warm I shed my sweatshirt by noon and put on a short-sleeved shirt. Crisp nights, warm days, sunny skies, gentle breezes, turning leaves. The golden time, and the harvest continues as if it were high summer rather than midfall. Monday, more yellow pattypans. Enough on hand for Kate to stuff a couple that night with couscous, corn, onions, and peppers, and freeze a few for the winter. Also more Big Beef slicers, enough for me to make a tomato sauce for the pattypans to bake in, with basil, parsley, garlic, and chili powder. A Mexican sort of concoction that Kate invented during a family reunion back in August -- so rich and tasty now with the whole wheat couscous, we both agreed it's ready for a recipe contest. More slicers on the back porch, and more turning ripe on the vines. And more zucchini to go with the batch already in the crisper, enough for two or three dinners.

Habitat of the Month





Pacific Rainforest
Common Raven

The Pacific rainforest is properly named—it is one of the rainiest places in the United States. Majestic fir, cedar, hemlock, and spruce trees grow in the rainforest. These evergreen trees keep their green needles all year long and make cones for seeds. Not much sunshine gets through the thick forest top, but thousands of plants and animals that like moist shade and mild weather flourish here.

Within the sound of ocean waves, the common raven lives in the lush green rainforest. You can easily observe these large birds with their strong powerful legs and wedge-shaped tails. Both male and female ravens have glossy black bodies and shaggy throat feathers. They are omnivorous, which means they eat both plants and animals.

Ravens are social birds that use many different calls to communicate with each other.

They build deep, bowl-shaped nests high in the tall evergreens. The nests are lined with animal fur to keep their eggs and chicks warm.

Once, rainforests covered wide areas of the Pacific Northwest, but much of the original rainforest has been cut down and logged. Little is left outside protected parks. You can explore the habitat that havens call home all year round when you visit these rainforest parks.
