Galapagos Hammerhead Shark

||||||||||||||||||||||||||||||||||||||||
A hammerhead shark tagged in the Galapagos Islands has been tracked to Cocos Island in Costa Rica and the Malpelo Islands in Colombia. The Galapagos National Park and the Charles Darwin Foundation, in conjunction with other organizations such as Conservation International (CI) and the World Wildlife Foundation (WWF), and with the technical assistance of a group of researchers from the University of California at Davis, have implemented a project to mark sharks in the Galapagos Marine Reserve. The goal is to establish migration patterns of these species, both within the Galapagos islands and between other "hot spots" in the region. Over the past two years, more than 100 ultrasonic and satellite tags have been placed on hammerhead sharks in the Galapagos. Receivers have been installed on the islands Darwin, Wolf and other islands in the archipelago and other islands the region. Through this project, sites of greatest aggregation of sharks have been identified, and the information necessary to improve the management and conservation of the sharks has greatly increased. One of the most important results was that the evidence was found that a hammerhead shark tagged in the Galapagos migrated to the Cocos Islands, Costa Rica and Malpelo, in Colombia. This confirms the existence of a biological corridor between the islands and demonstrates that sharks have preferences for certain sites or "hot spots". "It is necessary to continue this research to identify what attracts the sharks to follow certain routes and stay in some "hot spots," and with this information apply management measures to adequately conserve these species which are vital to the health of marine ecosystems "said Eduardo Espinoza of the Department of Marine Research of the Galapagos National Park. The project will continue with the installation of new monitors on Seymour, Champion, Santa Fe, Fernandina, Canal Bolivar, and Isle de la Plata (Manabi). Along with the shark census, monitoring of several oceanographic parameters will take place to better understand the hammerhead migration patterns.

Marcela Aguinaga, Minister of Environment, signed a land swap between the Municipal Government of Santa Cruz and the Galapagos National Park, with the assistance of hundreds of citizens who will benefit from this exchange. The Municipal Government of Santa Cruz, led by its mayor Leopoldo Bucheli Mora, has been working with the Galapagos National Park to arrange a swap of 100 acres of a farmland, located in Santa Rosa, in the Santa Cruz highlands, for 70 hectares of land located in the National Park area, near the urban area of Puerto Ayora. The report indicated that the land in the highlands has a high ecological value, whereas the land in Puerto Ayora is where the stone was extracted for the construction of the road to the Canal Itabaca and has much lower ecological wealth. After a process, which involved legal feasibility reports and detailed ecological inventories of the land to be exchanged, the Galapagos National Park forwarded the information to the Ministry of Environment for its review. The Minister of Environment, Marcela Aguinaga signed the document that will allow the exchange, which will create space for housing for more than eight hundred permanent residents. "Santa Cruz is the island which has fewest acres of urban area but has 60% of the population of the archipelago. With this good attitude on the part of the Ministry of Environment and the Galapagos National Park, we realize that there is openness to maintain the balance between the Galapagos ecosystems and population centers," said Mayor Bucheli Mora. He also said that housing projects in the exchanged land will be built with environmental parameters. |
