Names that relate to cowboys and cowgirls, the American West, that also have a nature meaning.

Names with a Western Nature Vibe

More unusual than Forest or Forrest, Field is a nature name that is simple, evocative, and fresh--sort of the male equivalent of Meadow.
Field and Fields are both relatively common surnames, noted bearers including department store owner Marshall Field, poet Eugene Field (Wynken, Blynken and Nod) and actress Sally. Those with the plural include W.C. Fields, cookie company founder Debbi, and entertainers Gracie and Kim Fields.
 Fielding is a very usable extension.

Field

The field of nature names is constantly expanding to include all species of flowers and trees and animals and birds and even fish. In addition to its appeal for anglers, Pike recalls Zebulon Pike, the explorer who discovered and gave his name to Pike's Peak.
 While Pike also shares the friendly feel of names like Mike and Ike, the word pike can also be a noun or verb referring to a long sharp weapon used to do not-very-friendly things to people. It is also one syllable away from a slur against Traveller people heard in the UK, so maybe this is one to avoid.
