BLM Wild Horse and Burro Evaluation, January 29, 1997
7. SELECTIVE REMOVAL POLICY
Findings:
The BLM's selective removal policy provides field office
guidance for identifying wild horses that may be removed from
public lands for adoption. Within HMAs, only "adoptable" horses
5 years of age and younger may be removed. For horses outside of
a HMA and on public lands, adoptable horses 9 years of age and
younger may be removed for adoption. The remaining horses are
returned to the HMA.
Selective removal, as broadly defined, has increased the
overall effectiveness and improved the public's perception of the
BLM's WH&B adoption program. BLM has been successfully moving
towards or achieving AMLs on many HMAs. As a result, horses have
been gathered and placed successfully, feedlots have been
eliminated, and the number of horses in sanctuaries have been
substantially reduced.
However, selective removal as interpreted and applied to
some HMAs has had negative effects and has failed to contribute
towards achieving a "thriving ecological balance." In areas
where BLM started with the number of horses far exceeding
carrying capacity, application of selective removal has resulted
in horse populations with age, sex, and social structures that
may threaten their viability. In some instances, selective
removal has prevented BLM from removing enough horses to achieve
and maintain AMLs.
Recommendations:
The Team recommends:
- Selective removal should remain as the fundamental
guidance when removing horses. Where AMLs cannot be achieved
using selective removal without recurring negative effects,
interim removal criteria for the HMA needs to be developed to
ensure viable populations on healthy, sustainable habitats. The
interim criteria may result in removal of fewer adoptable horses
in some HMAs to achieve AMLs. When it is necessary to remove
horses for which adoption demand has not been identified, special
supplemental handling to enhance their adoptability will be
necessary. Supplemental handling may require additional time to
allow horses to attain good health, special handling of older
horses, and extra marketing for these horses.
- On areas such as the Nevada Horse Range where sex ratios
and age structures have been significantly altered by selective
removals, the responsible wild horse specialist must very closely
monitor the herd to make sure enough young horses are returned to
the range after gather operations to ensure viability of the
herd. The number of young horses to return should be determined
through careful analysis using all available data, and the wild
horse population model.
- As the Strategic Plan is updated, the selective removal
policy should be reviewed.
- When selective removal is not effective in achieving
herd objectives, interim criteria should be developed and
employed for each herd until AMLs can be achieved.
- The NPO should establish guidelines for developing
interim removal criteria.
- When developing interim removal criteria, BLM's
population model should be utilized and incorporate all available
data for the herd(s) in question. BLM's population model is a
computer based management tool which allows wild horse and burro
specialists to forecast herd population trends given a set of
parameters. Specialists using the program can also run scenarios
to predict what might happen to a herd population should changes
occur in one or more of the variables.
