| The only plant restriction that I know exists in Nevada is the taking of native plants from their natural habitat. You can't take e.g. Yucca, other native succulents and conifers from the wild and taking them home. The plant restrictions in AZ and CA are due to agricultural pests and larvae residing in plants and fruits/vegetables coming in. Non native plants, such as eucalyptus, have diseases that can't be controlled because pest are here, but their biological controls aren't. Southern California has year round mild temperatures and therefore year round pests in many areas. They can't risk having anymore. That was the case of the med fly. Without frost, some deaths have been reported because of human interaction with killer bees. Their populations are controlled in part by cold winters like Nevada has. See the bolded section in the attached link (2nd paragraph) |
