WHAT IS AN ECO-SYSTEM? Ecosystem or biocenosis is a

segment of nature/ biosphere consisting of a community of living beings and the abiotic/physical environment both interacting and exchanging materials between them.

Ecosystem can be temporary (e.g. rain water pond) or permanent, natural or man-made (e.g. aquarium, agriculture), small or large.

Biotic Components: They include all living beings

present in an ecosystem producers, consumers and decomposers. The components are connected through food, its contained energy and a web of interrelationships.

Abiotic Components: They include temperature, light,

wind/air current, humidity/precipitation, water and topography.

Eco-system services Modification of the climate Maintenance of the hydrological

cycle Erosion control and soil formation Maintenance of O- and N-Cycles Waste and toxic chemical treatment Pest Management Carbon storage; maintain the C-

Cycle

THE HUMAN IMPACT ON ECO-SYSTEM

Increased population growth:› Increasing our biotic potential.› Decreased our environmental

resistance.

Contributions to ecosystem degradation:› Introduce species› Eliminate natural predators› Alter abiotic factors› Reduce biodiversity › Misunderstand the role of fire

Have we exceeded our carrying capacity?

IMPLICATIONS FOR HUMAN We need to protect and manage the natural

environment to maintain the goods and services vital to human economy and survival.

Establishing a balance between our own species and the rest of the biosphere should be a practical goal for all of us, if not also a moral goal.

Adaptive Ecosystem Management: an approach that accepts uncertainty of our knowledge base and flexible to change as new information is gathered; the goal is to balance our exploitation with an ecosystem’s capacity to renew goods and services.

conclusion As the world’s population grows and natural resources dwindle, the creation of parks and protected natural areas is not enough to solve the problem of forest destruction. The farms, forests and tourism businesses with which we work not only manage their own lands sustainably but they also function as an integral part of the larger landscape -- keeping trees standing, preventing erosion, protecting waterways and soils, providing wildlife habitat and reducing the risk of fires and other destructive activities. Together, sustainably managed businesses and neighboring protected areas can form a thriving mosaic that nurtures ecosystems, wildlife and people.
