Forest biodiversity provides ecosystem services and contributes an estimated 4% to the GDP. The rapidly expanding agriculture in the forest landis a significant threat to the forest Sal ecosystem. Biological invasions are probably the most significant environmental threat to the maintenance of natural forest ecosystems in North America and elsewhere. Forest ecosystems identified as being particularly vulnerable to the impacts of climate change include: mangroves, boreal forests, tropical forests, cloud forests and dry forests. Coniferous forests are mostly evergreen trees and deciduous forests are generally broadleaf trees. Forests have long been threatened by a variety of destructive agents. Due to this 'unsustainable' resource-use, once productive forests and grasslands have been turned into deserts and wasteland have increased all over the world. and conversion to agricultural land are the most visible threats to forests worldwide. A forest ecosystem is not just about the forest environment, however. They are a complex, functional system of interacting and often interdependent biological, physical, and chemical components, the biological part of which has evolved to perpetuate itself. The magnitude of this problem necessitates increased efforts to reduce the incidence and impacts of pest invasions. Forest ecology is The disappearance of the forest is called deforestation. The tallest and most distinctive mangrove is the red mangrove (Rizophora mangle).

The primary contemporary drivers of tropical forest biodiversity loss include direct effects of human activities such as habitat destruction and fragmentation (land-use change), invasive species and over-exploitation, as well as indirect effects of human activities such as climate change (Millennium Ecosystem Assessment 2005). Abiotic factors such as windthrow and fires can devastate forests while biotic factors such as insect pests, diseases and animal damage can seriously affect their health and productivity. 2.2 Ecosystem baseline and threats assessment 9 2.2.1 Review of existing literature 9 2.2.2 Stakeholder workshops 11 2.2.3 Mapping 12 2.3 Economic valuations 13 2.3.1 Economic approach 13 2.3.2 Step 1: Filter and sort ecosystem services 14 2.3.3 Step 2: Establish ecosystem unit values 15 European forest ecosystems - State and trends.
