COMMERCE CITY, Colo. (AP) - Hundreds of young people will be clearing weeds and planting trees from Hawaii to Vermont under a federal program that depends on private funding.

The government is putting in $1.9 billion of the $6.7 billion for the project that Interior Secretary Sally Jewell announced Thursday. Greg Knadle of the nonprofit National Fish and Wildlife Foundation says most of the rest is coming from Wells Fargo.

Jewell and Knadle spoke at the Rocky Mountain Arsenal National Wildlife Refuge. Some of the more than 600 young people employed under the project this year will be working at the refuge, a grassland park near Denver.

In addition to Colorado, projects are planned in Alaska, Arizona, California, Hawaii, Idaho, Indiana, Kentucky, Michigan, Montana, Nevada, New Mexico, New York, Oklahoma, Oregon, South Dakota, Utah, Vermont, Washington and Wyoming.
