The term forest-dependent people is used to describe any of a wide variety of livelihoods that are dependent on access to forests, products harvested from forests, or ecosystem services provided by forests, including those of Indigenous peoples dependent on forests. [70]
Forests have an enormously important role to play in the global ecosystem. Forests produce approximately 28% of the Earth's oxygen (the vast majority being created by oceanic plankton), [3] they also serve as homes for millions of people, and billions depend on forests in some way. Likewise, a large proportion of the world's animal species live ...
Genetic diversity also ensures that forest trees can survive, adapt and evolve under changing environmental conditions. Furthermore, genetic diversity is the foundation of biological diversity at species and ecosystem levels. Forest genetic resources are therefore important to consider in forest management. [16]
An ecosystem (or ecological system) is a system formed by organisms in interaction with their environment. [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors.
Bhitarkanika is the second largest mangrove ecosystem in India. [5] Pichavaram Mangroves (Tamil Nadu): Situated near the town of Chidambaram, the Pichavaram mangroves are one of the few large mangrove forests in Tamil Nadu. This forest features a unique network of channels and islands, attracting tourists for boat rides and birdwatching. [6]
Mangrove Cover: Mangrove forest is a salt tolerant forest ecosystem found mainly in tropical and sub-tropical coastal and/or inter-tidal regions. Mangrove cover is the area covered under mangrove vegetation as interpreted digitally from remote sensing data. It is a part of forest cover and is also classified into three classes viz. very dense ...
The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products including food and medicine, and contribute to rural livelihoods.
An ecosystem's area can vary greatly, from tiny to vast. A single tree is of little consequence to the classification of a forest ecosystem, but is critically relevant to organisms living in and on it. [2] Several generations of an aphid population can exist over the lifespan of a single leaf.
