Temperate Deciduous Forests A Project by: Angell Brake, Brittany Shea, Cassidy Butler, Robin Blagdon, and Damian Hirschkorn. Deciduous Vegetation --Type of vegetation that sheds its leaves during winter or dry seasons Temperate Deciduous Forests Temperate deciduous forests are found in the Eastern parts of Canada, below the boreal forests Deciduous forests have four seasons: spring, summer, fall and winter caused by the position of the sun and rotation of the Earth. During the summer months the temperature will range from 75 to 86 degrees. The soil conditions in the TDF are fair & Fertile. The annual precipitation in the deciduous forest is about 75cm to 150cm Soil Conditions People often marvel at the many different types of trees comprising these forests, such as oaks, maples, hickories, walnuts, and beech. However, they tend to overlook the soils at the bases of these temperate deciduous trees, which provide the trees with the nutrients necessary for life and growth. Alfisols; Ultisols; & Rocky Soils Alfisols Also known as brown forest soils, alfisols have two distinct layers: a top layer, consisting primarily of dead leaves, and a subsoil, which has a high content of clay Ultisols Ultisols provide poor aeration and lack nutrients. While primarily brown in color, ultisols often contain streaks of red or yellow Rocky Soils These Soils are dry and unfertile. Only small deciduous trees, like hickories, are able to grow in rocky soils. Interesting Facts The Deciduous Forest’s have a lack of Evergreens The Largest Forest in the world is A Temperate Deciduous Forest. It is found in Northern Russia and Has over 3.5 Million Acers of Trees! Humans have often colonized places in the Temperate Deciduous Forest, as well as harvesting the wood for timber. As a result, less than a quarter of the original forests are left. Threats to the Temperate Deciduous Forests This biome has been very extensively affected by human activity, and much of it has been converted into agricultural fields or urban developments. Air pollutants from fuels we burn are destroying forests, killing our wildlife and poisoning the soil. Acid Rain Global Warming The introduction of non-native plant and animal species to the Deciduous forest can destroy the balance of the forest. Plant Life Plants in the Temperate deciduous forests adjust their growth and activity to the seasons of the year. ->Oak Trees ->Eglantine ->Birch Trees ->Red Maple Tree ->Sugar Maple Trees Dogwood, Oak, Maple, Elm, and Birch are among the largest plants found in the temperate deciduous forest biome of Canada. Small plants like wild berry bushes and flowers have adapted to bloom and reproduce quickly in the spring before the trees’ leaves bloom and take up most of the sunlight. Mosses and Lichens are also ever present on the trunks of trees and covering the ground. Dominant Animal Life There are many different types of plants and animals found throughout the temperate deciduous forest biome. The main types of animals found here in Canada are: The Red-Tailed Hawk, The Bald Eagle, which has who hunts mostly adapted to live in higher regions small prey such as of trees and mountains where mice and squirrels. many other species of large predator birds cannot live. The Black Bear, which helps to control the population of many small species of prey animals such as rabbits and chipmunks. The Coyote has adapted to live almost everywhere and The Fox and Red Fox, can wipe out smaller species who eat mostly small which it preys on in only a prey and wild berries. matter of a few years.
