Native pastures that are dominated by the local guinea grass are common throughout St. Croix. This is a highly productive grass, well adapted to St. Croix conditions and should, therefore, be considered as a valuable resource to the island's livestock industry. Through mismanagement, however, many pastures have deteriorated to the point where hurricane grass has taken over. If the remaining pastures are to be maintained in a productive state, management criteria must be established. Cutting heights and frequencies are being studied to help maintain the integrity of these high producing swards, while surveys are being conducted to monitor changes in species composition.
