| 1 Listed
in one or more Southwestern state(s) or Mexico. Highest listing shown: (E)
endangered, (T) threatened, (S) sensitive
2 The impact assigned in this report
varies from the BISON-M assigned impact as follows: (1) In the absence of
other supporting information in the "Life History" and
"Management Practices" sections of the BISON-M listing, a rating
of "Beneficial" for "Livestock grazing; controlled (vs un-controlled)"
was interpreted to mean that less adverse impact is better than greater
adverse impact, and therefore beneficial in a relative sense whereas it is
adverse in an absolute sense. These species were placed in the
"Adversely Impacted" section of this report. (2) BISON-M
assigned an impact of "variable" but other information contained
in the "Life History" and "Management Practices"
sections of the BISON-M listing indicated that the impact of grazing is
most probably either adverse or beneficial as shown in this report. |
