Strategic conservation in farmed and urban landscapes can disproportionately increase biodiversity. Nick Haddad has worked for three decades to understand how to conserve landscapes to benefit pollinators and other species. He has created large experiments to test the role of targeted conservation efforts. For example, landscape corridors through urban and farmed landscapes can created superhighways...
A book about planting for monarchs (and for motivated readers and gardeners) is not quite as wondrous as monarchs and their individual life cycles, their host relationship with milkweeds, or their annual migrations in North America, but it is something of a miracle. Only a few decades ago, the concept of creating native-plant gardens was...
