|A mesic deciduous forest in North Eastern Iowa along Twin Springs Creek near Decorah. This Mesic forest is dominated by Maple, Basswood, and some Elm, Hackberry, and White Pine.|
|Early succession mesic deciduous forest composed mostly of Bigtooth Aspens but also a few Sumac trees.|
Being the uplands have an abundance of fruits they are also home to an abundance of birds. Choke Cherries, Dogwood berries, Raspberries, Black Cherries, and Goose Berries are just some of the more common fruits produced here. There is nearly continuous production of one type of fruit after another through out the summer, supplying a continuous food supply to the animals, and especially birds that reside here during the summer. These fruits are highly adapted to birds and are in-fact designed to have birds eat them. A fruits generally bright color simply says "eat me!" to any passer-byer (but don't do this unless you absolutely know what the fruit is, there are poisonous brightly colored fruits such as Poison Ivy!!!). When a bird eats these fruits the seeds pass right through their digestive tract and are deposited elsewhere, thus the bird aids the transportation of the seeds to colonize new locations.
Nuts are also abundant in the upland forest. Acorns, Walnuts, and Hickory nuts are abundant in the fall, supplying food for animals and birds of all types. Everyone knows squirrels love nuts, but so do deer, bear, raccoon, chipmunks, and large birds such as woodpeckers, Blue Jay, and Turkey. These animals often gorge themselves on nuts when they ripen in the fall. The high fat content of nuts makes them a great food to fatten animals up for winter. Some of the other common birds to the upland forest are Warblers of all types, Cardinals, Wood Thrush, Indigo Bunting, Fly Catcher, Gnat Catcher, and Rose Breasted Grossbeak. The best time to see these birds is early in the morning.
