Mar 21, 2023 · The 2022-2023 report shows a 22% decline in forest area when compared to last year, down from 7.02 acres to 5.46 acres this winter. The second report, Forest Degradation at the Core Zone of the Monarch Butterfly Biosphere Reserve , found 145 acres of forest have been degraded, a major increase when compared to the 47 acres lost in the previous year.
Feb 7, 2024 · Eastern migratory monarch butterfly populations decrease by 59% in 2024. New data detailing the abundance of the eastern monarch butterfly colonies wintering in central Mexico's forests estimate that the species occupied only 2.2 acres during the 2023-2024 winter season—59% less than the previous year when scientists observed 5.5 acres.
At the wintering sites in central Mexico, monarch population size is compared from year to year by the number of hectares (one hectare = 2.5 acres) occupied by trees containing monarchs. WWF and CONANP have been monitoring this area since 2004, with similar data from 1993-2003 collected by the Monarch Butterfly Biosphere Reserve (MBBR).

In 2016, the scientists began their work restoring the 10 hectares of land affected by illegal logging. As part of the restoration plan, the team divided the space into different sections of land. The strips on the borders and closest to the nearby forest were not touched. There, they put their faith in natural regeneration. About 70 percent of the...
Since 2007, Sáenz-Romero has created climate models in a joint effort with Gerald Rehfeldt from the Moscow Forestry Sciences Laboratory in Idaho, which is affiliated with the USDA Forest Service. The goal was to understand how climate change affects forest species. These models show Sáenz-Romero that, in the case of Mexico, cloud and coniferous for...
Just over 10 years have passed since scientists from UMSNH began documenting the effects of climate change on the trees in the region. In 2010, for example, researchers were contacted by residents of the Indigenous community of Nuevo San Juan Parangaricutiro, in Michoacán, to help them understand what was happening with their trees. On a national l...
Upon observing the effects of climate change on different forest species, Canadian researchers have begun what they call “assisted migration”; Helping trees, such as conifers, migrate to areas of higher altitudes, where they can best resist changing climatic conditions. In Mexico, Sáenz-Romero, Blanco García, and others have started to implement th...

The 2022-2023 report shows a 22% decline in forest area when compared to last year. Another report found that 145 acres of forest have been degraded at the core zone of the Monarch Butterfly Biosphere Reserve, a major increase when compared to previous years. Forest degradation impacts far more than butterflies.
