Review of Xerces Society’s Milkweed Guide

Many of us are aware of the monarch’s population decline that has been well documented by researchers. Weather, habitat destruction of overwintering grounds in California and Mexico, and loss of food source on migration routes have caused great concern in the last few years. The Xerces Society’s insight into factors that influence monarch butterfly populations has pointed to many things we cannot control. However, the increased production and planting of the monarch food plants, milkweeds, is certainly an environmental movement that can be achieved on a large scale in the United States.
