8-1 Chapter 8 Creating ClimateSmart Pollinator Habitat along Roadsides 8.1 Introduction More than 98 percent of climate scientists agree that climate change is occurring and that human activities, primarily the burning of fossil fuels and deforestation, are the cause. The effects are already being felt across the country in rising temperatures and increased frequency of extreme weather events.

Chapter 8. Creating Climate‐Smart Pollinator Habitat along Roadsides 8-4 8.5 Increasing Climate Resiliency for Pollinators Increasing climate resilience for pollinators requires a multifaceted approach. Creating and restoring habitat, increasing habitat connectivity, and reducing other stressors are all key components for increasing pollinator climate resilience.

Chapter 8. Creating Climate‐Smart Pollinator Habitat along Roadsides 8-5 8.5.3 Reducing Additional Stressors Reducing stressors (i.e., drivers of pollinator declines; see Chapter 3) to pollinators such as pesticide exposure, habitat loss, and invasive species is important because these different stressors can interact with each other and with climate change to magnify negative effects on pollinators.

Chapter 8. Creating Climate‐Smart Pollinator Habitat along Roadsides 8-6 native bees nest in wood or pithy-stemmed plants. Retaining downed logs and snags where possible will provide nesting habitat for some of these species, while planting native, pithystemmed plants like goldenrod or wild rose will provide nesting habitat for others (see Chapter 7 for a plant list that includes species used for nesting by cavity-nesting bees)
