French Guiana - Environment

Environment

French Guiana is home to many unique and important ecosystems: tropical rainforests, coastal mangroves, savannahs, inselbergs and many types of wetlands. French Guiana has one of highest levels of biodiversity in the world, in terms of both flora and fauna. This is due to the presence of old-growth forests (i.e. ancient/primary forests), which are biodiversity hotspots. The rainforests of French Guiana provide shelter for many species during dry periods and terrestrial glaciation. These forests are protected by a national park (the Guiana Amazonian Park) and six additional nature reserves. The International Union for Conservation of Nature (IUCN) and the European Union (EU) have recommended special efforts to protect these areas.

Following the Grenelle Environment Round Table of 2007, the Grenelle Law II was proposed in 2009, under law number 2010-788. Article 49 of the law proposed the creation of a single organization responsible for environmental conservation in French Guiana. Article 64 proposes a "departmental plan of mining orientation" for French Guiana, which would promote mining (specifically of gold) that is compatible with requirements for environmental protection. The coastal environment along the N1 has historically experienced the most changes, but development is occurring locally along the N2, and also in western French Guiana due to gold mining.

5,500 plant species have been recorded, including more than a thousand trees, along with 700 species of birds, 177 species of mammals, over 500 species of fish including 45% of which are endemic and 109 species of amphibians. The micro-organisms would be much more numerous, especially in the north, which competes with the Brazilian Amazon, Borneo and Sumatra. This single French department has at least 98% of vertebrate fauna and 96% of vascular plants as found in all of France and its overseas territories.

The threats to the ecosystem are habitat fragmentation by the roads, which remains very limited compared to other forests of South America, impacts of immediate and deferred Petit-Saut dam(fr) of EDF, of gold mining, poor control of hunting and poaching facilitated by the creation of many tracks and the appearance of all-terrain vehicles. Logging remains moderate because of the lack of roads, on both the difficulty of climate and terrain. An ordinance of 28 July 2005 extended the Forest Code at French Guiana, but with important exceptions and modifications. In an approach that will be sustainable, concessions or free transfers may be granted by local authorities or other entities for use by persons traditionally deriving their livelihood from the forest, but the means no longer always used traditional means, and the Guianese ecosystem being vulnerable, the impacts of logging or hunting may be important.

The beaches of the natural reserve of the Amana, the joint Awala-Yalimapo in the west, is a marine turtle nesting site exceptional. This is one of the largest worldwide for the leatherback turtle.

Famous quotes containing the word environment:

    In a land which is fully settled, most men must accept their local environment or try to change it by political means; only the exceptionally gifted or adventurous can leave to seek his fortune elsewhere. In America, on the other hand, to move on and make a fresh start somewhere else is still the normal reaction to dissatisfaction and failure.
    —W.H. (Wystan Hugh)

    For those parents from lower-class and minority communities ... [who] have had minimal experience in negotiating dominant, external institutions or have had negative and hostile contact with social service agencies, their initial approaches to the school are often overwhelming and difficult. Not only does the school feel like an alien environment with incomprehensible norms and structures, but the families often do not feel entitled to make demands or force disagreements.
    Sara Lawrence Lightfoot (20th century)
