Monarch populations in the West face an even greater chance of extinction at 99% by the year 2080. The Fish and Wildlife Service is accepting public comments on its proposal until March 12, 2025.
The number of monarch butterflies in California is in sharp decline this year. This is the second-lowest population recording since tracking began in 1997. Biologists say record-high late summer ...
The Western population of the monarch butterfly hit a near-record low with fewer than 10,000 found living in ... This year's Western monarch count marks a sharp decline from the last three years ...
Insects with population trends documented by the International Union for Conservation of Nature, for orders Collembola, Hymenoptera, Lepidoptera, Odonata, and Orthoptera. A 2020 meta-analysis found that globally terrestrial insects appear to be declining in abundance at a rate of about 9% per decade, while the abundance of freshwater insects appears to be increasing by 11% per decade.
Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
Declining butterfly populations have been noticed in many areas of the world, and this phenomenon is consistent with the rapidly decreasing insect populations around the world. At least in the Western United States, this collapse in the number of most species of butterflies has been determined to be driven by global climate change ...
The latter, at the time of its decision, estimated a decline of 99.9% for the western population since the 1980s and 84% for the larger eastern population since the mid-1990s.
Dwindling numbers and the following decline of ecosystems will lead to greater loss of biological wealth over time, as without pollinators many plants will not grow or bloom. Many scientists have analyzed data, revealing that the Monarch butterfly population has declined significantly since the 1980s and the 1990s.
