Which two individuals are credited with advocating for hunting regulations in the early conservation movement?

The advocacy for hunting regulations in the early conservation movement is primarily attributed to Theodore Roosevelt and George Bird Grinnell. Both played crucial roles in shaping early conservation policies in the United States.

Theodore Roosevelt, as president, was instrumental in promoting wildlife conservation. He established numerous national parks, forests, and monuments, significantly contributing to the preservation of natural habitats. His belief in the sustainable use of wildlife led to the establishment of hunting regulations, aiming to manage wildlife populations responsibly.

George Bird Grinnell, an influential figure in the conservation movement, was a strong advocate for the protection of American wildlife. He co-founded the Audubon Society and emphasized the importance of regulating hunting to restore bird populations and protect habitats. Grinnell's writings and activism complemented Roosevelt's policies, highlighting the need for comprehensive wildlife management that included hunting regulations.

The combination of their efforts laid the foundation for modern wildlife conservation practices, making them pivotal figures in the early conservation movement focused on hunting regulations.
