Tjóðarlundir í USA

Hugtakið tjóðargarður sá dagsins ljós í Sambandsríkinum Amerika um 1870 so hvørt sum íbúgvararnir fluttu seg longur og longur vestureftir. Niðursetufólkini samtyktu, at heilt serliga náttúran í Yellowstone-økinum var fólkaogn. Heimsins fyrsti tjóðargarður varð tí grundlagdur í Yellowstone í 1872. Týdningarmesta endamálið í dag við tjóðargørðum er at tryggja lívfrøðiliga margfeldinum.
