Forest ecology is the scientific study of the interrelated patterns, processes, flora, fauna and ecosystems in forests. The management of forests is known as forestry, silviculture, and forest management.
A forest is a piece of land with many trees. Many animals need forests to live and survive. Forests are very important and grow in many places around the world. They are an ecosystem which includes many plants and animals. Temperature and rainfall are the two most important things for forests.
Common species are cedar, cypress, pine, spruce, redwood, and fir. There are still some deciduous trees such as maples and many mosses and ferns — resulting in a Jurassic-looking forest.
We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.
Plants and algae, for example, are producers. In the forest's ecosystem, the trees, shrubs and moss are all producers. They turn water and sunlight into the energy they need to live and grow, through a process called photosynthesis.
There are three major types of forests, classed according to latitude: Tropical. Temperate. Boreal forests (taiga)
Deserts are areas of land that are arid, or dry, and get less than 10 inches of rain per year. Deserts can be hot or cold. Plants and animals in the desert ecosystem have adaptations that allow them to survive the lack of rainfall and extreme temperatures.
Insects, spiders, slugs, frogs, turtles and salamanders are common. In North America, birds like broad-winged hawks, cardinals, snowy owls, and pileated woodpeckers are found in this biome. Mammals in North American temperate deciduous forests include white-tailed deer, raccoons, opossums, porcupines and red foxes.
The benefits provided by forest ecosystems include: goods such as timber, food, fuel and bioproducts. ecological functions such as carbon storage, nutrient cycling, water and air purification, and maintenance of wildlife habitat. social and cultural benefits such as recreation, traditional resource uses and
Trees contribute to their environment by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife. During the process of photosynthesis, trees take in carbon dioxide and produce the oxygen we breathe.
The importance of forests cannot be underestimated. We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms.
The benefits provided by forest ecosystems include: goods such as timber, food, fuel and bioproducts. ecological functions such as carbon storage, nutrient cycling, water and air purification, and maintenance of wildlife habitat.
An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Abiotic and biotic factors work together to create a unique ecosystem.

Forest Types. Forests can be classified according to a wide number of characteristics, with distinct forest types occuring within each broad category. However, by latitude, the three main types of forests are tropical, temperate, and boreal.
Structure of Ecosystem:
The structure of an ecosystem is basically a description of the organisms and physical features of environment including the amount and distribution of nutrients in a particular habitat. It also provides information regarding the range of climatic conditions prevailing in the area.LOCATION: Most temperate, deciduous (leaf-shedding) forests are located in the eastern United States, Canada, Europe, China, Japan, and parts of Russia. Deciduous forests are broken up into five zones. The firstzone is the tree stratum zone.
Threats to our forests
Some are natural factors such as fire, insects, disease, or wind and ice storms. Others, such as climate change, invasive species and forestland conversion, are a result of human activity.Plants form the critical base of food chains in nearly all ecosystems. Through photosynthesis, plants harvest the energy of the sun, providing both food and habitat for other organisms. For example, plants are fed upon by insects, which may be eaten by birds, which are in turn are eaten by birds of prey, and so on.
