Movements and home range of salt marsh harvest mice Academic Article uri icon


  • We radio-tagged 44 endangered salt marsh harvest mice (Reithrodontomys raviventris) during 1991 and 1992 at Mare Island Naval Shipyard, Solano Co., California, to document movements and home range size of this species. Mean distance moved between 2-hour observation periods was 11.9 m, and mean home range area was 2,133 m2. There was no significant difference for mean distance moved or size of home range between sexes; between males that had abdominal testes or those that had scrotal testes; or among females that were nonreproductive, developing mammaries, had developed mammaries, or were pregnant. For all salt marsh harvest mice, greatest mean distances moved and largest areas of home range occurred during June, whereas smallest mean distances moved and smallest home ranges occurred during November. There were no significant differences among months for either mean distance moved or home range area. Movement patterns of salt marsh harvest mice revealed that mice crossed roads, levees, and canals.
