By the turn of the century the land was owned by several lumber companies, with plans to cut the remaining trees down, as sequoia and giant sequoia with their thick trunks were seen as great sources of lumber at the time. This again caused a chorus of public outcry by locals and conservationists, and the area continued to be treated as a tourist attraction. The Yosemite protection was gradually extended to most sequoias, and Calaveras Grove was joined to California State Parks in 1931.
