Here are a few. Follow the link for more.
Vegetation
The natural vegetation of North America has been significantly modified by human activity, but its general nature is still apparent over much of the continent. The most notable forest is the taiga, or boreal forest, an enormous expanse of mostly coniferous trees (especially spruce, fir, hemlock, and larch) that covers most of southern and central Canada and extends into Alaska. In the eastern United States a mixed forest, dominated by deciduous trees in the north and by various species of yellow pine in the southeast, has mostly been cleared or cut over, but a considerable area has regrown since the 1940s. In the western portion of the continent, forests are primarily associated with mountain ranges, and coniferous trees are dominant. In California, the redwood and giant sequoia grow to enormous size. A great mixture of species characterizes the tropical forests of Mexico.
The vegetation cover in the drier parts of the continent is made up mainly of grassland and shrubland. The central plains and prairies of the United States and southern Canada were originally grass covered, but much of the natural flora has been replaced by commercial crops. The dry lands of the western United States and northern Mexico are sparsely covered with a variety of shrubs and many kinds of cactus. Beyond the tree line in the far north is a region of tundra, containing a mixture of low-growing sedges, grasses, mosses, and lichens.
Animal Life
The native wildlife of North America was once numerous and diverse, but the spread of human settlement has resulted in contracting habitats and diminishing numbers. In general, the fauna of North America is similar to that of the northern areas of Europe and Asia. Notable large mammals include several kinds of bear, the largest being the grizzly; bighorn sheep; bison, now only in protected herds; caribou; moose, called elk in Europe; musk-ox; and wapiti. Large carnivores include the puma and, in southernmost regions, the jaguar; the wolf and its smaller relative, the coyote; and, in the far north, the polar bear. One species of marsupial, the common opossum, is indigenous to the continent. A few of the many reptiles are poisonous, including the coral snake, pit vipers such as the rattlesnake and copperhead, and the Gila monster and beaded lizard of the southwestern United States and Mexico, the only poisonous lizards in the world. A great variety of finfish and shellfish live in the marine waters off North America, and many kinds of fish are found in its freshwater rivers and lakes.
Mineral Resources
North America has large deposits of many important minerals. Petroleum and natural gas are found in great quantity in northern Alaska, western Canada, the southern and western conterminous United States, and eastern Mexico; huge beds of coal are in eastern and western Canada and the United States; and great iron-ore deposits are in eastern Canada, the northern United States, and central Mexico. Canada also has major deposits of copper, nickel, uranium, zinc, asbestos, and potash; the United States contains great amounts of copper, molybdenum, nickel, phosphate rock, and uranium; and Mexico has large reserves of barite, copper, fluorite, lead, zinc, manganese, and sulfur. All three countries have significant deposits of gold and silver.

Well, according to the CIA (they're not watching me now), the United States' natural resources are:
coal, copper, lead, molybdenum, phosphates, uranium, bauxite, gold, iron, mercury, nickel, potash, silver, tungsten, zinc, petroleum, natural gas, and timber.
Naturally.

In addition to all the minerals and the vegetation, I think the most important and often forgotten, is it's "Human Resources" without which all the other resources would be useless.
