### Mega gardening

Big as life and twice as opinionated, the renowned preservation biologist Daniel Janzen spoke for The Long Now on Friday, April 9, 2005. His perspective on preservation may be jarring to some: "It's ALL Gardening".

Dan Janzen is most widely known for his heroic efforts helping set all of Costa Rica on a preservation path, ensuring that the mega-diverse nation continues indefinitely as a haven for science and eco-tourism. His particular focus, Guanacaste Conservation Area, was recently declared a World Heritage Site by UNESCO. His ongoing work there in field taxonomy and innovative preservation practices led to his receiving the Crafoord Prize (1984), the Kyoto Prize (1997), and the Albert Einstein Science Prize (2002). Professor Janzen teaches at the University of Pennsylvania.
