The U.S. Fish and Wildlife Service and Pima County say they are seeking ways to plan for human development while protecting native plants, animals and habitats.
The agencies are hosting public meetings to discuss a 15-year program known as the Multi-Species Conservation Plan in Pima County.
Officials say the plan is "essentially Pima County's application for a permit, under the Endangered Species Act, to take threatened and endangered species, when the taking is incidental to an otherwise lawful activity such as construction."
The county is asking for permits on 44 species, and it is cooperating with the Fish and Wildlife Service.
The federal agency is accepting comments on its environmental impact statement and the county's conservation plan until March 15. To learn more and to comment, go to the Pima County government website.
