the puma with others in danger of extinction. Species such as deer, coyotes, owls, eagles and foxes have diminished in part due to the contamination of the waters of the Centenario Dam. The most common species of the area are the rabbit, skunk, squirrel, opossum, doves, other species of birds, rattlesnakes and coral snakes. Economy After tourism, agriculture and livestock is the most important economic activity of the municipality, employing just under fifteen percent of the working population. This is despite the fact that it is not very profitable due to the high operating costs, obsolete technology, insufficient credit and inadequate commercialization. The main crops are corn, beans, sorghum, alfalfa, grapes, chili peppers, tomatoes and tomatillos. Tequisquiapan is the largest producer of pasilla chili peppers in Mexico, but this production is under pressure due to imports of a similar chili pepper from Peru and China, and sold as pasilla. The municipality is asking for a registration to mark authentic pasilla chili peppers from the imported variety. 19,703 hectares of the municipality is ejido or other communally owned property. These are owned by thirteen ejidos and one agricultural and livestock cooperative. 11,078 hectares of the municipality are used for agriculture, with 4,867 irrigated and the rest planted during the rainy season. Livestock mostly consists of the raising of bulls for bullfights. Some of the better known ranches for this include Xajay, La Gloria, San Martín and Fernando de la Mora. Outside of this, the municipality is not especially dependent on the raising of livestock although cattle, pigs, sheep, goats and horses can be found. The town contains a bullring which hosts bullfights as well as exhibitions of flamenco dance and concerts. There is a Bullfight Fair in March. The growing of grapes in the municipality began with wine grapes in the early 1960s and has grown to be one of the most important agricultural products, featured on Tequisquiapan's municipal seal. Reds, whites and rosés are produced but most are sparkling wines. The major producer in the municipality is Viñedos La Redonda, about twelve km outside of the town proper. The vineyards are mostly planted with vines of French origin such as Merlot, Cabernet Sauvignon and Malbec for reds and Chenin blanc and Trebbiano for whites. It has guided tours for visitors, especially at harvest time. One major producer of table grapes is Rancho San Miguel. The ranch extends over forty hectares
