SEMARNAT noted that despite heavy rains and winds, the arrival of thousands of butterflies (Danaus plexippus) occurred this Monday, but the first records of their presence in Mexico this year, have been since October 7 in Ciudad Acuña, Coahuila.

Upon arrival, the monarch butterfly forms clusters in the oyamel forests and surveys hibernation sites over the next five months.

The species is included in the Conservation of Species at Risk (Procer) and the Action for the Conservation of Species (PACE) programs, which involve different instances of the environmental sector such as the National Commission of Protected Natural Areas (Conanp), the National Commission for the Knowledge and Use of Biodiversity (Conabio).

The monarch needs us

The Ministry of the Environment and Natural Resources invited the population to join the Protect the Monarch campaign, in which it will be possible to record the observation of specimens in the National Monitoring Platform of the Monarch Butterfly.

MORE THAN 40% OF THE MONARCH BUTTERFLY THAT HIBERNATES IN MEXICO IS FOUND IN EL ROSARIO

Of all the Monarch Butterfly that arrived at the forests of the country, to Michoacán and the State of Mexico, little more than 40% is concentrated in the El Rosario Sanctuary, which is located in the municipality of Ocampo, they assured in a press conference, Homero Gómez González and the Regional Delegate for Tourism, Georgina Herrera Tello.

This is because this lepidopteran is looking for nearby water and thick forest, and that is what El Rosario has; thanks to the reforestation actions and to which they brought water from a distance of eight kilometers. Also, unlike in past seasons, the Monarch is not found above the sanctuary, but 200 meters from the entrance is a huge colony, which begins to be seen in significant amounts from the parking area, commercial area and much to little distance.

Official data show that the current butterfly population increased 144% last year, so the figure is historical, it had never happened. "We have many people working to take care of it, from guides, and others who are responsible for making recommendations to tourists as they do not touch them, do not step on them, take pictures without flash, do not make noise, they also tell them that you can not take plants of the sanctuary, "said Gómez González. Currently, there are around 174 ejidatarios who are part of the administration of the sanctuary, and the instruction is to care for the monarch.

Homero Gómez González said that from November to date, more than 75,000 tourists have come to El Rosario, and it is expected that at the end of the season they will have 150,000 or more, both international and national. The current number of visitors may have been higher because in two weeks because of the shortage of gasoline, there were many who canceled their visit or postponed, but despite what happened the figures are good, and the population of the butterfly in this place is historic.

Georgina Herrera Tello said that these visits translate into an important economic spill for the eastern region, and added that it has had to do the promotion work by the agency that represents in this part of the state.
