In an effort to remind communities of the importance of forests and the benefits they receive from them, March 21 is set aside internationally to celebrate World Forestry Day. This concept originated at the 23rd General Assembly of the European Confederation of Agriculture in 1971, and since then, countries around the world have set up programmes and policies aimed at the sustainable management of forest resources to provide for their social, economic, ecological and cultural needs. In observing World Forestry Day today, the Environmental Management Authority (EMA) would like to encourage the people of Trinidad and Tobago to take time to appreciate the value of our forest resources. Historically, forests have played important social and cultural roles in the lives of many people, especially those of indigenous communities.
Today, many are realising that forests offer much more than just timber. Forests provide recreational opportunities and contribute to our health and wellbeing, as well as the regulation of local temperatures and protection of drinking water supplies. Forests also act as carbon sinks and have a mitigating effect on climate change. When forests grow, carbon is removed from the atmosphere and absorbed in wood, leaves and soil. They are considered to be carbon sinks, because forests can absorb and store carbon over an extended period of time. This carbon remains stored in the forest ecosystem, but can be released into the atmosphere when forests are burned. Trees form the foundations of many natural systems, and as such provide a wide range of products (timber, fruit, medicine, beverages, fodder) and services (carbon sequestration, wind breaks, water quality and quantity control, coastal protection, shade, beautification, erosion control, soil fertility). The forests of Trinidad and Tobago are home to a wide variety of faunal biodiversity which facilitate pollination, seed dispersal and germination.
This internationally-recognised environmental day also aims to provide opportunities for people to learn how forests can be protected, managed and used sustainably for these many purposes. The day is set aside to promote education and awareness of the importance of forests and the benefits of planting trees. According to a Greek proverb, "A society grows great when old men plant trees whose shade they know they shall never sit in." With 2010 declared International Year of Biodiversity (IYB), the EMA agrees that the need to demonstrate the relevance of forest biodiversity to everyone's lives has never been greater. Forest biodiversity refers to all forms of life found in forests, including plants, animals, fungi, micro-organisms, their roles in nature, as well as varying forest types, such as mangrove, elfin and seasonal evergreen forests. Examples of biodiverse forests in this country include Matura National Park, which was declared an environmentally sensitive area in 2004, and Main Ridge Forest Reserve in Tobago, which is the oldest protected watershed in the western hemisphere, declared in 1776.
Nonetheless, humans are destroying forest biodiversity at an alarming rate. The conversion of forests to agricultural land, overgrazing, unsustainable management, introduction of invasive alien species, infrastructure development, mining and oil exploitation, man-made fires, pollution and climate change are all having negative impacts on forest biodiversity. This degradation makes forests more fragile, and diminishes the services provided by forests to humans. It was for these reasons that the EMA embraced the opportunity to collaborate in a project with the Ministry of Planning Housing and the Environment, the Forestry Division of the Ministry of Agriculture, Land and Marine Resources, University of the West Indies and the Institute of Marine Affairs, among others, called the Nariva Restoration and Carbon Sequestration and Livelihoods Project.
This project will ultimately see the replanting of 1,300 hectares of the Nariva Swamp, in areas that were formerly deforested by large-scale rice farmers more than a decade ago. The rehabilitation with native species of trees to restore the ecology of the area is only a part of this historic project. A first for Trinidad and Tobago will be the carbon sequestration focus of capturing carbon dioxide in the trees and vegetation, through the natural growth of these plants. Nariva Swamp, the country's largest and most biodiverse wetland, has been declared an environmentally-sensitive area under the Environmentally-Sensitive Area Rules, 2001. It has the most varied vegetation of all wetlands in Trinidad and Tobago, with distinct zones of tropical rainforest, palm forests, mangroves and grass savanna/marsh.
