TE-24. Within the range of southwestern willow flycatcher, livestock grazing will conform to the guidelines described in the "Not Likely to Adversely Affect" section of Guidance Criteria for Determinations of Effects of Grazing Permit Issuance and Renewal on Threatened and Endangered Species (BLM and US Fish and Wildlife Service, Arizona and New Mexico 1999) or any subsequent agreed-upon amendment to these guidelines.
The current guidance criteria for Not Likely to Adversely Affect states:
Disturbance of individuals or nests, predation, or parasitism would not be likely because livestock use would not occur in occupied habitat during any time of the year.
Suitability for nesting flycatchers would not be reduced because livestock grazing in unoccupied suitable habitat would not occur during the growing season (key vegetation characteristics are maintained or enhanced and conditions promoting cowbird parasitism are avoided).
Cowbird parasitism would be unlikely because grazing would occur greater than five miles from occupied habitat during the breeding season, or
Monitoring of flycatcher nests demonstrates that no cowbird parasitism is occurring when livestock use occurs closer than 5 miles, but not within, occupied habitat, or
cowbird parasitism would be unlikely due to the physical juxtapositions of habitat type, terrain, facilities, elevation, and other factors.
Progression of potential habitat towards becoming suitable within 10 years would not be impeded by livestock grazing (e.g. regeneration or maintenance of woody vegetation is not impaired by trampling, bedding, or feeding)
Sufficient monitoring is in place to demonstrate that habitat suitability is being maintained or enhanced in accordance with two and four above. Such monitoring would continue through the life of the grazing action under consideration.
TE-25. Conservation of Federal threatened or endangered, proposed, candidate, and other special status species is promoted by maintaining or restoring their habitats.
