Lake Xochimilco and the canal system Xochimilco is characterized by a system of
canals, which totals approximately 170 km2. These canals, and the small colorful boats that float on them among artificially created plots of land called
chinampas, are internationally famous. These canals are popular with Mexico City residents as well, especially on Sundays. These remaining canals and their
ecosystem were declared a
World Heritage Site in 1987, for the purpose of saving them. An important part of this ecosystem is a
willow tree called a "
ahuejote" that is native to the shallow waters of the lake/canals. These trees stem
erosion, act as wind breakers, and support the reproduction of a variety of aquatic species. As of 2003, there were only 600 axolotls known to exist in the wild. In addition to species that live in the area year round, the
wetlands here host about 40% of the
migratory bird species that come to Mexico (roughly 350), using the wet areas around Xochimilco for nesting. Many of these come from the United States and Canada. However, much of this habitat has been urbanized. About 700 species have been found in the area overall. Some of the migratory species include
pelicans,
storks,
buzzards and
falcons. The destruction of the last of these canals began in the 1950s. At that time, groundwater pumping under the city center was causing severe subsidence. These wells were closed and new ones dug in Xochimilco and other southern boroughs. High rates of extraction have had the same effect on water tables and canals began to dry. Since then reclaimed wastewater has been recycled to flow into the Xochimilco canals to supplement water from natural sources. However, this water is not potable, containing bacteria and heavy metals and the canals still receive untreated wastewater and other pollution Another major problem, especially in the past two decades, has been the population explosion of Mexico City, pushing urban sprawl further south into formerly rural areas of the Federal District. This prompted authorities to seek
World Heritage Site status for the canals and the pre-Hispanic chinampa fields to provide them with more environmental protection. Each year the borough loses six hectares of former lakebed to illegal settlements. According to the borough, about 90,000 people in Xochimilco live in illegal settlements, such as those in ecological zones, and 33,804 families live illegally on the chinampas. The most problematic are those closest to the canals, which cause the most pollution. However, some need to be maintained because the axolotls are using them for reproduction purposes. Another major problem is the loss of trees, especially junipers in the ecological zone. Over sixty percent of the area is considered to be serious deforested and eighty percent of the junipers have the parasitic plant
mistletoe. Since being declared a World Heritage Site, there have been attempts to rescue the canal system. The first major effort occurred between 1989 and 1994, which was called the “Rescate Ecológico.” It had the goal of constructing a large artificial lake for tourism and sports covering 360 hectares, ten times the size of the lake in
Chapultepec Park. These would be divided into two parts called the Ciénega Grande and Ciénega Chica on the side of the
Periférico Sur. It would also include the creation of a chinampa zone and areas for culture and commerce and elevated buildings over the two sides of the Periférico Sur similar to those in the San Jerónimo area. However, this plan was stopped by agricultural communities in the area, which have a long history of defending their rights. Since then, the area has been urbanized. It was replaced by
a much smaller lake, with an ecological park and plant market. However, it is still estimated that because of the continuance of urban sprawl, the remaining canals and protected land will disappear within fifty years. Today, only about 5,000 chinampas, all affixed to the lake bottom, still exist in their original form, surrounded by canals and used for agriculture. The rest have become solid ground and urbanized. In the center of Xochimilco, there are about 200 chinampas, covering an area of 1,800 hectares. However, one reason the number has decreased is that smaller chinampas have been combined to create larger ones. As they can produce up to eight times the amount of conventional land, After this, he began to hear whispers, footsteps, and anguished wails in the darkness even though his hut—hidden deep inside the woods of Xochimilco—was miles away from civilization. Driven by fear, he spent the next fifty years hanging more and more dolls, some missing body parts, all over the island in an attempt to appease what he believed to be the drowned girl's spirit. After Barrera's death in 2001—his body reportedly found in the exact spot where he found the girl's body fifty years before—the area became a popular tourist attraction where visitors bring more dolls. The locals describe it as "charmed"—not haunted—even though travelers claim the dolls whisper to them. The dolls are still on the island, which is accessible by boat. The island was featured on the
Travel Channel show
Ghost Adventures and the
Amazon Prime show
Lore. It was also featured in
BuzzfeedUnsolved where Ryan and Shane visited the island with a guide, who lead them around the island during the night. It was also featured on the show Expedition X in season 1 episode 3, where Phil Torres & Jessica Chobot explore the mysteries of the island & the dolls. ==History==
