the Chiricahua leopard frog.
    (2) What activities are allowed on private, State, or Tribal land? 
Incidental take of the Chiricahua leopard frog will not be considered a 
violation of section 9 of the Act, if the take results from livestock 
use at or maintenance activities of livestock tanks located on private, 
State, or Tribal lands. A livestock tank is defined as an existing or 
future impoundment in an ephemeral drainage or upland site constructed 
primarily as a watering site for livestock.
    (c) California tiger salamander (Ambystoma californiense).
    (1) Which populations of the California tiger salamander are covered 
by this special rule? This rule covers the California tiger salamander 
(Ambystoma californiense) rangewide.
    (2) What activities are prohibited? Except as noted in paragraph 
(c)(3) of this section, all prohibitions of Sec.  17.31 will apply to 
the California tiger salamander.
    (3) What activities are allowed on private or Tribal land? 
Incidental take of the California tiger salamander will not be a 
violation of section 9 of the Act, if the incidental take results from 
routine ranching activities located on private or Tribal lands. Routine 
ranching activities include, but are not limited to, the following:
    (i) Livestock grazing according to normally acceptable and 
established levels of intensity in terms of the number of head of 
livestock per acre of rangeland;
    (ii) Control of ground-burrowing rodents using poisonous grain 
according to the labeled directions and local, State, and Federal 
regulations and guidelines (The use of toxic or suffocating gases is not 
exempt from the prohibitions due to their nontarget-specific mode of 
action.);
    (iii) Control and management of burrow complexes using discing and 
grading to destroy burrows and fill openings;
    (iv) Routine management and maintenance of stock ponds and berms to 
maintain livestock water supplies (This exemption does not include the 
intentional introduction of species into a stock pond that may prey on 
California tiger salamander adults, larvae, or eggs.);
    (v) Routine maintenance or construction of fences for grazing 
management;
    (vi) Planting, harvest, or rotation of unirrigated forage crops as 
part of a rangeland livestock operation;
    (vii) Maintenance and construction of livestock management 
facilities such as corrals, sheds, and other ranch outbuildings;
    (viii) Repair and maintenance of unimproved ranch roads (This 
exemption does not include improvement, upgrade, or construction of new 
roads.);
    (ix) Discing of fencelines or perimeter areas for fire prevention 
control;
    (x) Placement of mineral supplements; and
    (xi) Control and management of noxious weeds.
    (d) California red-legged frog (Rana aurora draytonii). (1) Which 
populations of the California red-legged frog are covered by this 
special rule? This rule covers the California red-legged frog (Rana 
aurora draytonii) rangewide.
    (2) What activities are prohibited? Except as noted in paragraph 
(d)(3) of this section, all prohibitions of Sec.  17.31 will apply to 
the California red-legged frog.
    (3) What activities are allowed on private or Tribal land?

ranching activities include, but are not limited to, the following:
    (i) Livestock grazing according to normally acceptable and 
established levels of intensity in terms of the number of head of 
livestock per acre of rangeland;
    (ii) Control of ground-burrowing rodents using poisonous grain 
according to the labeled directions and local, State, and Federal 
regulations and guidelines (In areas where California red-legged frogs 
and California tiger salamanders coexist, the use of toxic or 
suffocating gases is not exempt from

[[Page 133]]

the prohibitions due to their nontarget-specific mode of action.);
    (iii) Control and management of burrow complexes using discing and 
grading to destroy burrows and fill openings (This exemption does not 
apply to areas within 0.7 mi (1.2 km) of known or potential California 
red-legged frog breeding ponds.);
    (iv) Routine management and maintenance of stock ponds and berms to 
maintain livestock water supplies (This exemption does not include the 
intentional introduction of species into a stock pond (including non-
native fish and bullfrogs) that may prey on California red-legged frog 
adults, larvae, or eggs.);
    (v) Routine maintenance or construction of fences for grazing 
management;
    (vi) Planting, harvest, or rotation of unirrigated forage crops as 
part of a rangeland livestock operation;
    (vii) Maintenance and construction of livestock management 
facilities such as corrals, sheds, and other ranch outbuildings;
    (viii) Repair and maintenance of unimproved ranch roads (This 
exemption does not include improvement, upgrade, or construction of new
