Public outcry prompted the city to hire another expert, who corroborated Bell's study. Butterflies are only able to fly when it's warm. If it's too cold for them to fly and they end up on the asphalt where there are no long grasses for them to crawl onto for safety, they are often crushed by passing vehicles. This is about the problem of terminating a miracle. We're talking about an ecosystem here.
Private property is of little consequence to wildlife.
The only effect it has on them is that it kills them. Meyberg is also concerned about falcons and the eight sea otters and two pups now living in the bay that, along with surfers, could be affected by oil and grease runoff from additional pavement. In light of such concerns, environmentally friendly alternatives to asphalt, such as crushed granite, were proposed but shot down due to maintenance issues. However, grease traps will be required if the parking lot is built, though critics claim they are ineffectual during heavy rains. It may even be the only multigenerational migrating creature in the world.
