That's because the driving force behind the changing forests are earthworms, which play a key role in recycling nutrients in the soil but which may also be altering habitat for plants, salamanders, birds and other wildlife. What's Related Non-Native Earthworms May Be Wiping Out Rare Plants Earthworms Threaten Minnesota Forests Acid Rain Threatens Forests In More Ways Than Previously Thought related stories Related sections: Only a few forest stands are known to be affected to date, according to University of Rhode Island soil scientists Josef Görres and José Amador, but they say the threat to forests is real. Most of the earthworm species found in the Northeast are not native to the area.

Index MICHIGAN FORESTS FOREVER TEACHERS GUIDE FOREST ECOLOGY BASICS A forest is a collection of biological organisms and non-biological factors. From an ecological perspective, the definition of a forest includes all these things, from the trees to the bacteria, and the soil type to the microclimates. See the " Tree Basics " page for more about the definition of a forest. Forest management systems are rooted in forest ecology (pun intended!). There are three groups of concepts with forest ecology, or the ecology of just about any natural system. Each of the three groups of concepts interact with other to variable degrees, at variable times, and in variable ways. Composition : These are the pieces of the puzzle. Structure : This is how the pieces are arranged. Function : This is what each piece does and the interactions among the pieces.

Home Facilities Programs Curriculum ... Events Ecology Education on the Southern Coast of Maine What Programs Does Ferry Beach Provide? Ferry Beach Ecology School (FBES) is a non-profit educational organization dedicated to providing ecological education to 3rd-8th grade classes. Our interdisciplinary ecology curriculum focuses on teaching hands-on lessons in basic ecology by using the outdoors as a classroom a classroom where learning occurs through exploration, scientific investigation, discovery and sensory awareness. FBES naturalists take students to a variety of ecosystems residential programs , as well as day programs and outreach programs to public and private schools. Why Do Classes Come to Ferry Beach? A trip to FBES can be a once in a lifetime opportunity for students to explore and learn about ecosystems such as tidepools, beaches, dunes, salt marshes and coastal forests- places that many of them may never have seen before. The experience of being away from home and learning to live with and get along with others is also invaluable. School teachers from all over New England use this experience as an integral part of their science curriculum. Pre-visit and post-visit activity manuals as well as free teacher training during your visit to Ferry Beach Ecology School help to ensure that the week can be incorporated into the regular school year.

THE FISHER MUSEUM AT HARVARD FOREST I n 1907, Harvard acquired 2 000 of its 3 000 acres of forest in Petersham, Massachusetts (65 miles west of Cambridge) to serve as an outdoor classroom, a laboratory, and a demonstration site for field experiments. In the 1930s, Richard T. Fisher, the first director of the Harvard Forest, was able to commission, through the generosity of Ernest Stillman, a series of 23 dioramas depicting the history of central New England Forests, their management and ecology. These models, made by the studio of Guernsey and Pitman in Cambridge, form the core of the Fisher Museum (dedicated in 1941), and represent an internationally renowned educational and artistic achievement. Additional exhibits relate to the forest history, ecology, and ongoing research. T he Harvard Forest was named a National Science Foundation Long-Term Ecological Research site in 1988. Subsequently, it became the northeastern field site for the National Institute for Global Environmental Change. Location: Petersham, MA 01366 Telephone: (508) 724-3302 Harvard University Museums

Ceska verze The Institute of Forest Ecology was established as a scientific workplace of the University of Agriculture, Brno in 1968. The main task of the Institute is to develop the theory of ecology and to interpret it in forestry. Research activities are concentrated on the analysis of Central European floodplain forests, study of structure, production and processes in Norway spruce stands with particular emphasis on anthropic activities. For a number of years, the Institute provided for projects of the International Biological Programme (IBP) and later on the UNESCO Man and the Biosphere Programme. At present, the Institute is a scientific workplace of the Faculty of Forestry and Wood Technology and problems of sustainable management in forests are studied, especially preservation of biodiversity, adaptation of forests to climatic changes, spruce monoculture conversion to mixed forests and stress identification and its response in forest ecosystems. In addition to research work in the field of forest ecology, the Institute activities are also oriented to the education of doctoral students.

Forest ecology - much more than trees When we think of forests, we often think only of the trees that grow there. And while many tree species are impressive - such as the 82m (274 ft) California Sequoia that is the earth's largest living thing or Methuselah, a California Bristlecone Pine that dates almost 4,770 years - trees represent only a tiny percentage of life in the forests. Part of what makes forests so amazing are the complex relationships between flora and fauna - like the incredible salmon forest story. Forest friends Critters like insects, slugs, voles, and shrews are perhaps not as majestic as ancient trees, but they are as important to the health and longevity of a forest. Mosses and lichens are also essential elements of a forest, and if any of these pieces of the puzzle go missing, the entire forest can be critically impaired, especially in the long- term. These often-considered lesser species can have the same function as a canary in a coal mine, warning us when human activities are undermining the forest ecosystem. And in order to protect valuable species - like spotted owls or marbled murrelets - we must protect their forest habitat. The lowly mushroom is an excellent example of how a visually small part of the forest is actually a significant element of the forest ecology.
