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 8-2 Increased temperatures can cause rutting, cracking, and buckling of roads. Nationally, 60,000 miles of bridges and roads run through coastal floodplains, which are at increased risk from flooding and storms.

In addition to using multiple IPCC scenarios, scientists typically use multiple climate models that differ in their sensitivity to different parameters.

Species most likely to be negatively affected by climate change include resource specialists (e.g., species that use only a narrow subset of plants as larval host plants or for pollen)

Chapter 8. Creating Climate‐Smart Pollinator Habitat along Roadsides 8-6 Provide Nesting Habitat for Native Bees When many people think about bees they think about honey bee hives or bumble bee nests; however, the vast majority of bees are solitary -- nesting in narrow tunnels in the ground or in wood. About 70 percent of native bees nest in the ground, and installing vegetation like bunch grasses that can provide access to small patches of earth will provide areas for these species to build nests (Chapter 2, Pollinator Biology and Roadsides)

For similar reasons, diverse plant communities may be more resistant to pressure from invasive species or diseases, and pressure from invasive species is especially predicted to increase in this region.

This helps reduce the impacts of flooding, which will be critical in many areas where increased flooding is projected, and in coastal areas where sea level rise will increase the frequency of coastal flooding.
