Forest ecosystem functions

The forests have been hitherto valued as land banks rather than a valuable resource of its own right providing essential goods and services for livelihood generation. According to MEA (2005) the benefits derived from the forests are collectively referred to as ecosystem service functions (ES). The ES have been categorized into The Cooperative Forest Ecosystem Research Program CFER was developed to conduct research that facilitates sound management of forest ecosystems, with emphasis on meeting priority information needs of the Bureau of Land Management and the Oregon Department of Forestry in western Oregon. Goals zProvide forest managers with new information to evaluate We call these numbers the “ecological production functions” the components of the ecosystem output that generate value as human benefits. We define it as five broad classes of ecosystem services: food production, coastal protection, water purification, carbon sequestration, tourism and recreation, as well as a range of non-use values (also ... Maintenance, conservation and appropriate enhancement of protective functions in forest management (notably soil and water); and Maintenance of other socio-economic functions and conditions.

Often called "the lungs of the world", forests play an enormous role in mitigating climate change, providing habitat for more than half the world's plants and animals, protecting watersheds, and preventing soil erosion. Yet population pressures and lax forest management threaten these crucial ecosystems all around the world. More frequent disturbance led to canopy opening but less debris deposition, and changed forest species composition, which may alter resilience in the face of future disturbances. Frequent hurricane disturbance causes forest ecosystems to retain less carbon and export more nutrients.

Foundation Our lab uses field and laboratory studies to understand disturbance effects on forest carbon, and the biogeochemical factors that regulate carbon and nitrogen dynamics in forest soil. Characterizing the ecological role of pyrogenic carbon is a major focus of our current work. Ecosystem ecology focuses on the interactions among living and non-living components of an ecosystem. 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 ecosystem is a natural woodland unit consisting of all plants, animals and micro-organisms (Biotic components) in that area functioning together with all of the non-living physical ...Functions of the forest: The forest performs a great number of functions, both as a natural formation and as a product of skilful human activity, when nature is harnessed to fulfil people's own needs. The value of particular functions of the forest is limited - an increase of one may occur at the expense of others.

Forest biodiversity can be considered at different levels, including the ecosystem, landscapes, species, populations and genetics. In high biodiversity forests this complexity allows organisms to adapt to continually changing environmental conditions and to maintain ecosystem functions. Forest ecosystems and biodiversity are strongly interlinked.
Ecosystem Services help measure the true cost of industrial development. Often, the impact industrial development has on the economy and job creation overshadows the cost it will have on surrounding lakes, forests, keystone species, and so on.
The ecosystem functions through several biogeochemical cycles and energy transfer mechanisms. Observe and document the components of the ecosystem which con- sists of its non-living or abiotic features such as air, water, climate and soil. Its biotic com- ponents, the various plants and animals.
A natural woodland area making it a suitable place for the survival of biotic and abiotic components, is usually termed as a forest ecosystem. A forest ecosystem consists of various plants, animals, and other micro-organisms, making it a natural habitat for them. The forest ecosystem plays an essential role in the environment.
Among terrestrial ecosystems, forests will be profoundly impacted by drier climatic conditions, with drastic consequences for the functions and services they supply. Simultaneously, biodiversity is known to support a wide range of forest ecosystem functions and services.
Dec 23, 2020 · This database facilitates the quantification of CO2 fluxes and pathways across different levels of integration (from photosynthesis to net ecosystem production) in forest ecosystems. The database fills an important gap for model calibration, model validation, and hypothesis testing at global and regional scales (Luyssaert et al. 2007).
Comprise of organisms that feed on dead matter and break it down to release chemical energy back into the soil for plants to re-use them. E.g. fungi, bacteria, insects, worms and others. Detritivores: feed on detritus matter (dead plants and animals) e.g. crab, vulture, termites, wood beetle and crayfish.
Mangrove forest ecosystem are made up of the mangrove vegetation that grow in the area of beaches and estuaries that are affected by the ocean tides, this ecosystem has a variety of functions (Bengen, 2000). Mangrove forest ecosystems have important benefits and functions as an economic resources and ecological resources for human life.
The functioning of forest ecosystems is characterised by energy and nutrient flows and cycling, biomass production and the decomposition of dead organic matter. Plants need nutrients and carbohydrates for biomass production and for other vital functions. Carbohydrates are produced by photosynthesis from carbon dioxide, water and nutrients.
The leaves also act as natural filters of air and water by removing particulate matter. A very important function of trees in the growing concrete-based world is in flood control. The roots hold soil in place, which would otherwise be washed away in heavy rains. Trees also act as natural barriers to the weather elements such as wind and snow.
An ecosystem is an ecological system: i.e. a group of organisms (this can include animals and plants as well as birds, bacteria and insects) that live together as a community. An ecosystem is usually a distinct system with its own special characteristics. So, a forest ecosystem is: A community of organisms living together in a forest.

This review focuses on temperate and boreal forest ecosystems and the roles of BVOCs in ecosystem function, from the leaf to the forest canopy and from the forest soil to the atmosphere level. Moreover, emphasis is given to the question of how BVOCs will help forests adapt to environmental stress, particularly biotic stress related to climate change.
We study how global environmental changes in climate, land-use (including forest management), biogeochemical cycles, ecosystem trophic structure, and invasions of non-native species affect biodiversity and the structure and function of terrestrial plant communities and forested ecosystems.
The Andrews Forest LTER program integrates research, outreach and education, and research-management partnerships to investigate forest and stream ecosystems in the Pacific Northwest. Climate change forecasts in the Pacific Northwest region portend drought, decreased snow packs, and increased wildfire.
Ecosystem functions are natural processes or exchange of energy that take place in various plant and animal communities of different biomes of the world. For instance, green leaves prepare food and roots absorb nutrients from the soil, herbivores feed on the leaves and the roots and in turn serve as food for the carnivores.
Forests are invaluable for their roles in biodiversity protection and climate regulation. Global climate change is impacting forests worldwide, and understanding such changes is critical to forest conservation and climate protection efforts. The CTFS - ForestGEO Ecosystems and Climate Initiative, led by Kristina J. Anderson-Teixeira, looks at how the globally distributed forests of CTFS-ForestGEO interact with the Earth’s changing climate system.
