Protecting Pollinators breaks down the latest science on environmental threats and takes readers inside the most promising conservation efforts. Many organizations have dedicated to researching and communicating the plight of the monarch butterfly. The single most important factor causing the decline of the Karner blue butterfly across its range has been the loss of habitat due to suppression of wild fires, clearing land for farming, and developing land for commercial and residential purposes. The butterflies that develop in late August shut down their reproductive systems and spend their energy migrating south back to Mexico, where the cycle begins anew. Butterflies are considered to be good indicators of a healthy environment and reflect the environmental impact of urban development.
