National parks are different from other federal lands in the United States. Beginning in 1872 with the establishment of Yellowstone, they were largely set aside to preserve for future generations the most spectacular and inspirational features of the country, seeking the best representative examples of major ecosystems such as Yosemite, geologic forms such as the Grand Canyon, archaeological sites such as Mesa Verde, and scenes of human events such as Gettysburg. But one type of habitat--the desert--fell short of that goal in American eyes until travel writers and the Automobile Age began to change that perception. As the Park Service began to explore the better-known Mojave and Colorado deserts of southern California during the 1920s for a possible desert park, many agency leaders still carried the same negative image of arid lands shared by many Americans--that they are hostile and largely useless. But one wealthy woman--Minerva Hamilton Hoyt, from Pasadena--came forward, believing in the value of the desert, and convinced President Franklin D. Roosevelt to establish a national monument that would protect the unique and iconic Joshua trees and other desert flora and fauna. Thus was Joshua Tree National Monument officially established in 1936, with the area later expanded in 1994 when it became Joshua Tree National Park. Since 1936, the National Park Service and a growing cadre of environmentalists and recreationalists have fought to block ongoing proposals from miners, ranchers, private landowners, and real estate developers who historically have refused to accept the idea that any desert is suitable for anything other than their consumptive activities. To their dismay, Joshua Tree National Park, even with its often-conflicting land uses, is more popular today than ever, serving more than one million visitors per year who find the desert to be a place worthy of respect and preservation.

Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.
