Most of the northern half, although covered with only a few inches of subsoil, is one of the most important henequen-raising regions of the world; the uncultivated area is under a dense growth of scrub, cactus, sapote wood, and mangrove thickets. Subsistence crops, tobacco, and cotton also are grown. Magnificent forests of tropical hardwoods in SW Campeche, Petén, and Belize provide the basis for a lumber industry. This area teems with tropical life, including the jaguar, the armadillo, the iguana, and the Yucatán turkey. Fishing is important along the Yucatán coast. Many of the peninsula's fine beaches and archaeological sites have been developed for tourism, which is a significant part of the peninsula's economy. By the early years of the 21st cent. resort development in Mexico on the peninsula's E coast was extensive, especially at Cancún and to its south along c.60-mi (100 km) stretch of beach popularly known as the Mayan Riviera. Yucatán also possesses large oil deposits, and Mexico in particular has developed a substantiael oil industry on the peninsula.
