Haiti and the Dominican Republic share the Caribbean island of Hispaniola. When tropical storm Jeanne hit Haiti and the Dominican Republic in September 2004, over 20 inches of rainfall occurred in 24 hours–more than a third of the rain that typically falls during an entire year. Forestry practices in these two tropical countries have been quite different. While the Dominican Republic's forests remain largely intact, most of Haiti's forests had been removed by 1990 as the rapidly growing population became increasingly dependent on subsistence farming in mountainous regions of the island. Tropical storm Jeanne created a national disaster for Haiti with over 3000 lives lost, but the Dominican Republic experienced very short-lived effects and only 18 deaths.
