context_page_description: The "Environmental Impact of the Big Cypress Swamp Jetport", unofficially known as the "Leopold Report" or the "Leopold-Marshall Report", was a report authored by hydrologist Luna Leopold of the United States Geological Service for the Department of the Interior and officially released on September 17, 1969. Arthur R. Marshall, formerly of the United States Fish and Wildlife Service, helped draft the report. It is considered the first ecological impact report in the state of Florida.
context_section_description: When the report was finally released, Leopold began by stating his strong opposition to the plan:  "Development of the proposed jetport and its attendant facilities will lead to land drainage and development for agriculture, transportation, and services in the Big Cypress Swamp which will inexorably destroy the south Florida ecosystem and thus the Everglades National Park."  A report from the National Academy of Sciences was subsequently published the next day supporting the findings of the Leopold report.
