Appendix 8

Species Distribution at High and Low Lake Elevations

This group of maps is the distribution of species by survey period during a high lake elevation year (1999) and a low lake elevation year (2001). These maps are arranged to contrast species use of the available habitat under two very different sets of conditions. Because these maps represent one point in time rather than a mean, missed surveys for a particular area and survey period show the same as a count of zero.
