The monarch butterfly has been listed as Endangered by the International Union for Conservation of Nature (IUCN), a global authority on the conservation status of species. An endangered listing means the species is likely to go extinct without significant intervention.
Over the past decade, the population has dropped between 22% to 72% globally. Monarchs east of the Rocky Mountain declined by 84% from 1996 to 2014. In the West, the population plummeted by 99.9%.
Monarchs need places to rest their wings, drink flower nectar, and lay their eggs on milkweed, which their baby caterpillars eat.
Here's what the National Wildlife Federation recommends:
The most common native milkweed in these parts has fuzzy leaves and an odd greenish-white bloom and can stand two-feet tall. During dry spring seasons, the hearty perennial is sometimes the ONLY plant blooming. Last year in Central Texas when we had an exceptionally wet winter, the Antelope Horns were not as pervasive as you would think. Too much moisture and too much competition from less hardy plants kept these guys laying low.
This common native milkweed in our area is sometimes called Green Antelope Horn Milkweed or Green Mlikweed and is the most common milkweed in the state of Texas. The Edwards Plateau is the western reach of its range, which starts in East Texas.
This plant is a host to the Monarch Butterfly. It can grow to 2 feet tall and has white, greenish-white to yellow flowers that bloom from March and December depending on location.
