There is a national effort to help rebuild the monarch butterfly population, and it is starting here in Minnesota. The number of monarchs has decreased by more than 90 percent since the 1990s, which is mostly due to the use of pesticides and weed killer.
Minnesotans love the Monarch — it’s the official state butterfly. But the only placethey can really be seen this summer are at places like the Aveda Butterfly Garden at the Minnesota Zoo in Apple Valley.
Scientists report a drop of nearly 60 percent in the number of Monarch butterflies making it to their winter home in Mexico this year — the lowest level since record-keeping began 20 years ago.
