APPENDIX H INVERTEBRATES OF THE LAKE TAHOE BASIN APPENDIX H INVERTEBRATES OF THE LAKE TAHOE BASIN Erik M. Holst and Matthew D. Schlesinger Table H-1—Documented and potential invertebrates of the Lake Tahoe basin. Species endemic to Lake Tahoe are noted with an “X”. Reliability codes: 1 = high-documented occurrence; 2 = moderate-potentially occurring based on at least two sources or identified in areas adjacent to the basin; 3 = low-potentially occurring based on a single source. Sources consulted: Frantz and Cordone (1966, 1996), Kimsey (pers. comm.), Manley and Schlesinger (in prep), NAMC (1999), and Storer and Usinger (1963).
