Restoration of Forests and Fires One of the most predominate ecosystems is the forest community. Covering about one-fourth of the land area on Earth‚ forests consist mainly of trees and other woody vegetation‚ growing closely together. The trees can be large and densely packed‚ as they are in the coastal forests of the Pacific Northwest‚ or they can be relatively small and sparsely scattered‚ as they are in the dry tropical forests of sub-Saharan Africa. Forests are complex ecosystems that also include

What Is a Forest Ecosystem? Forests are important ecosystems that provide environmental and economic benefits. Forest ecosystems are unique environments and are categorized based on the types and ages of trees‚ climate and soil. They impact the environment at scales ranging from local to regional‚ by influencing climate‚ nutrient dynamics and water movement. Forests are found all over the world‚ and they provide valuable economic and environmental services. Information About a Forest Ecosystem A forest

BEECH FOREST ECOSYSTEMS INTRODUCTION This essay will look at beech forest ecosystems‚ describing the main characteristics‚ along with pre-human and current distribution of beech forests. Vegetation structure and native fauna associated with the ecosystem will be looked at with examples of species given. Environmental effects such as altitude‚ latitude‚ rainfall and soil drainage‚ and how they can affect beech forests will be investigated. Anthropogenic effects will also be looked at‚ explaining

Environmental sciences ECOSYSTEMS RAINFOREST By: Christina L. Jackson The business dictionary definition of rainforest is a dense forest of evergreen trees growing in regions of heavy year-round rainfall in tropical latitudes (such as Amazon Basin‚ Borneo‚ New Guinea‚ North-East India‚ and Zair Basin) and warm temperate latitudes (such as Eastern Australia‚ Florida‚ South Africa‚ South Brazil‚ South and Central China‚ South Japan‚ and New Zealand’s North Island). Nearly half of these forests are in the Central

9: Ecosystem Approach Variation of Forests in Their Age‚ Makeup‚ and Origins A. 2 Major Types of Natural Forests 1. Old-growth/ Primary -uncut/ regenerated forest that has not been seriously disturbed by human activities/ natural disasters for 200 years or more - reservoirs of biodiversity (provide ecological niches for a variety of wildlife species) 2. Second- growth - stand of trees resulting from secondary ecological succession B. Tree Plantation/ Tree Farm/ Commercial Forest -managed

Effects of Human Activities on the Lake Ecosystem I. Introduction On the first exercise of the Environmental Biology class‚ the students have learned what an ecosystem is and what its significance to the survival of the living and non-living are through analysis of forest and agro-ecosystems. The ecosystem as the basic unit for ecological study (Evans‚ 1956) consists of the complex of interacting organisms inhabiting a region with all the non-living physical factors that make up their environment

The effects of human activity on ecosystems and biodiversity Agricultural Practice Biodiversity is a measure of the diversity among organisms in different ecosystems. "Diversity" in this definition includes diversity within a species and among species‚ and among ecosystems.’ Monoculture is when a farmer produces or grows one single crop over a wide area. The advantages to the farmer of monoculture are‚ “the reduced plant competition for nutrients‚ space and solar radiation‚ control of unprofitable

The effect of SARS on the human population February 2003‚ Asia reported an outbreak of severe acute respiratory syndrome‚ commonly known as SARS. SARS is a viral respiratory illness caused by the virus SARS-associated coronavirus (SARS-CoV). Within a few months the virus spread to over two dozen countries‚ causing SARS to be considered a global infection. The virus spread to North America‚ Europe‚ South America and Asia before it was contained in 2003. A total of 8‚098 people were infected by SARS
