Coconino National Forest Watershed Vulnerability Assessment, Southwest Region (R3)
Figures 4 a-b. Historic and existing distribution of selected aquatic species on the Coconino NF
Native Aquatic Species
The CNF supports a wide variety of native aquatic species. The distribution of these species has been
greatly reduced due to water development, degraded habitat, and invasive non-native species (see Figures
4 a-b). Species in the analysis include both native warm water fishes and herpetiles.
The CNF is home to an extensive list of Threatened, Endangered and Sensitive (TES) fish species. The
fisheries biologist selected four fish species for inclusion in the analysis, all of which are currently present
in subwatersheds within the analysis area (rather than downstream). The species selected for inclusion are
listed in Table 2. Several are listed under the Endangered Species Act, and on the CNF, some are
currently found only in the analysis area.
Four other listed, candidate or species of concern were included as resources in initial assessment efforts
but not carried forward due to their very limited distribution and co-location with other species. These
were Gila Trout (re-introductions of the species on CNF have been discussed), Red Rock Stone fly, and
the Fossil Springs and Page Springs spring snails.
