For some unknown reason the ecologically highly sensitive
areas of Laguna  Sontecomapan were not included in the
nuclear zones of the  Los Tuxtlas Biosphere.

In 2000 the University of Veracruz obtained a 15 year Mexican
federal concession to 375 acres of the most threatened area.

Los Manglares are now an Area Natural Protegida (nature
preserve) managed by the University of Veracruz. A small
mangrove replantation project has been completed and more is
planned.

In 2004 RAMSAR, an international wetland organization  added
Laguna Sontecomapan to its preservation list.
