A great post on the milkweed debate from LepLog. There are no easy solutions to stopping the decline, but don’t stop planting habitat for Monarchs as well as other endangered species. As usual, the answers are still coming in for a complex problem, just like the honeybee situation.
Very interesting. Oligoneuron rigidum (stiff goldenrod) is the plant mentioned. It seems it would be good to promote this plant both on and away from the coast for the benefit of foraging monarchs.
Yes, milkweed isn’t the entire solution. I have an entire field of goldenrod which I let grow!
