¶ … Heritage Sites in Danger
The United Nations Educational, Scientific, and Cultural Organization maintains a list of its own World Heritage Sites that are in particular danger at any given time. These sites may be cultural or biological; this essay will profile two such natural sites that deserve our immediate and urgent attention: The Galapagos Islands in Ecuador, and the Niokolo-Koba National Park in Senegal. In both cases, additional funding will help with desperately needed new protections. For each site, a summary of the unique diversity and biological inter-relationships will be provided. These assets will be followed by a discussion of the most pressing threats facing the areas, and then a description of why current protections are insufficient. Finally, a snapshot of the current status of the site will be offered.
Galapagos Islands
Since 1835, when Charles Darwin made the Galapagos Islands the focus of his ground-breaking research that ultimately led to his theory of evolution, this archipelago has been recognized as unique. The 19 islands that comprise the Galapagos are located approximately 1,000 meters off the coast of Ecuador. Only four of those islands are populated, but the rest host a steady stream of visitors. The Islands were initially added to UNESCO's list of Heritage Sites in 1978, and designated as a UNESCO Biosphere Reserve in 1984. Mounting threats moved the Galapgos to the Danger list in 2007.
Diversity & Biological Integrity
Marine animals thrive in this unique environment, created from volcanic activity that still has periods of high activity. The Galapagos are isolated from the mainland, which is part of the reason the site was such a productive research location for Darwin. An estimated 5,000 native species are supported there. Several species are found only there, including the land iguana, the giant tortoise, and several sub-species of finch. Since significant human settlements did not occur there until the 20th century, a vast web of biodiversity was able to thrive and prosper.
Threats
Many threats have contributed to the listing of the Galapagos Islands on UNESCO's "danger" list. Fishing is the most important resource extraction activity that impacts the health of biodiversity on the Islands. The waters surrounding the Islands have long been prolific fisheries, and the area supports a large human population of fishers. Recent increases in technology have meant a shift away from small-scale, subsistence fishers to more industrial scale exploitation of marine resources. Efforts to manage and regulate fishing have been stymied by incomplete enforcement capacities, and a thriving market for illegal marine products, such as shark fins, continues to exert extraction pressure on the region.
High rates of tourism are easily the most direct threat. Indeed, "modern tourists relish the magical opportunity to watch sharks in the shallow waters, swim with sea lions, and sit next to sea birds carrying out their mating rituals," (Novy, 2010: 67). So many visitors have a direct impact on the behavior and biology of the very species they are there to observe. Simultaneously, residents of the Islands have increased with the number of people living on the Islands having doubled in the last decade. Many of these new migrants do not have a vested interest in conservation and fail to adopt sustainable lifestyles that would reduce their overall impact.
Invasive species are one of the most pressing and worrisome threats, and experts agree that most invasive species are spread through the activities of human visitors. That is, as humans from around the world visit the Islands, they invariably -- and unintentionally -- deliver seeds of plants from their home countries to the fragile ecosystem of the Galapagos. New residents may bring domestic animals that they are accustomed to in their home countries, and then those animals escape and become feral. Until recently, no reliable quarantine system was in place to regulate the influx of invasive species.
Existing Protections
The Galapagos Islands are internationally renowned and have attracted a great deal of attention by preservationists. The Charles Darwin Foundation and the Galapagos Conservation Trust are just two examples of organizations that serve to study and protect the unique biological diversity found there. These organizations, in conjunction with international conservation groups, have established a number of both expected and innovate measures designed to protect the biodiversity found there. For example, incentive programs began in 1997 and seek to generate cooperation from an array of stakeholders. These incentive programs include increased enforcement for protections already established in policy documents, and the development of a certification program to ensure sustainable harvesting of marine and fishery products (Novy, 2010).
Proposed New Protections
In an effort to minimize the introduction of new invasive species, UNESCO has partnered with the Food and Agriculture Organization, the Charles Darwin Research Station and the Galapagos National Park. This collaboration will focus on improved community education, the development of a stronger inspection system for visitors, the eradication of existing invasive species, and, perhaps most importantly, the creation of a sustainable financing mechanism for long-term conservation.
Current Status
The isolation of the Islands has made it possible for the ecosystem to retain much of its original biodiversity despite pressures from tourism and invasive species. An estimated 97% of the Islands' native biodiversity is still in place today (Novy, 2010). However, the threats are mounting and without full deployment of new policies to guarantee ongoing protections, this number is sure to slip. Many international conservation organizations have made the Galapagos a focus of their work, not necessarily due to fear of immediate extinctions but more because of the immeasurable value of the biodiversity stock.
Niokolo-Koba National Park
Initially inscribed in 1981, the Niokolo-Koba National Park lies in eastern Senegal along the banks of the Gambia river. Troubled by civil strife, widespread commercial poaching, and ecological fragmentation, the Park was added to UNESCO's danger list in 2007.
Diversity & Biological Integrity
The Niokolo-Koba National Park is unparalleled in its rich diversity of fauna. The Park is situated in a riparian area that supports both fast gallery forests and extensive savannahs. Among the large mammals that populate the area are rare antelopes called Derby elands, chimpanzees, lions, leopards, and elephants. The Park also supports 330 species of bird, 38 reptile species and 20 amphibian species. Vegetation is lush and diverse, with an estimated 1,500 different plant species found there (UNEP). The River Gambia runs through the park. Average annual rainfall is 600-900mm in the Park, but these amounts have decreased dramatically in recent years, probably due to climate change.
Human Threats
Illegal poaching of wildlife is the most pressing danger facing this National Park. The decline in large mammals has been dramatic and leaves the entire ecosystem in a state of crisis. In 1990, there were an estimated 46,500 large animals in the Park; by 2006 there were only 900 left (UNEP). Chimpanzees in particular are threatened. The Niokolo-Koba National Park provides "the hottest, driest and most open chimpanzee habitat known," (UNEP) and the decline of these animals is particularly urgent.
Intense cattle grazing within the Park is a second major threat facing the Park. Most of the larger mammals in the Park were destroyed by 2006, likely the result of pressures faced by poachers and grazers. When the Park was established in the 20th century, thousands of traditional settlers were relocated to new lands outside of the Park. However, lasting resentments have made it difficult for Park officials to find cooperation among the indigenous groups that now live on the borders of the Park. Many of those groups continue to poach animals illegally and graze their domestic livestock without regard for Park conservation efforts.
Finally, another threat to the Park comes from a dam that is being planned for upstream. If the dam is built, experts fear that regular and seasonal flooding will stop; wildlife in the area depend on those natural weather patterns. The dam is favored by the Senegalese government, and it will be difficult to find a better source of new energy to serve the impoverished local population.
Existing Protections
Administered by the National Parks Directorate under the Ministry for the Environment and Protection of Nature, this Park, like many in the African continent, is a victim of under-funded state agencies who may try to protect it but lack the resources to do so. One of the most common methods used by Park rangers to help them keep a better eye on poachers is the use of fire. Clearing the forests increases their surveillance capacity but, at the same time, improves access for the very illegal users they are seeking to exclude. In 2006, a new public-private partnership was established with help from the Senegal government, the Dutch government, and outside donors.
