Title: U.S. Grassland Management


1
U.S. Grassland Management
  • Prescribed burns
  • Grazing intensity
  • Stocking
  • Rotation
  • Issues
  • Over-grazing
  • Exotic species
  • Public land policy
  • ESA species
  • Predator control

History of U.S. Public Grasslands 225 million
acres
  • 1880s Tragedy of the commons
  • 1932 Forest Service Study
  • 1934 - Taylor Grazing Control Act
  • Stop overgrazing
  • Improve and sustain range
  • Stablilize rangeland economy
  • Agencies
  • BLM -Bureau of Land Mgt.
  • US Forest Service

40 - 60 million bison killed
Replaced by cattle and sheep

So, regulating stocking rates works. But....

With overgrazing increasers invaders
replace decreasers
  • Best forage species decline due to over-grazing
    (decreasers).
  • Woodier, spinier, more fibrous, poor quality
    forage species increase (increasers).
  • Exotic species fill in empty spots (invaders)

Uses and Values in the National Grasslands - 4
million acres (20 places)
  • Spiritual Value for Native Americans
  • Wildlife Commons
  • Bring back the bison
  • Bring back predators
  • Restore prairie dog systems
  • Nature Tourism
  • Wildlife Hunting
  • Livestock grazing
  • Grass fed beef market growing
  • Grass feeding then to feed lots.

The U.S. Forest Service is in the process of
reevaluating management plans for North Dakota's
three national grasslands, comprising about 1.1
million acres of public land.

Work needed to restore public grasslands in the
great plains (mainly shortgrass prairies)
  • The Forest Service should manage for native
    species on all National Grasslands.
  • Conserve and restore prairie dog towns until
    black-tailed prairie dogs occupy a minimum of 10
    of the suitable habitat
  • Black-footed ferret recovery areas should be as
    large as possible.
  • Bison should be restored as wildlife on our
    National Grasslands at some level.
  • The U.S. Forest Service should actively encourage
    public land grazing permittees to switch their
    stock from cattle to bison.
  • All remaining roadless grassland areas should be
    proposed for wilderness designation.
  • Oil and gas development should be prohibited in
    areas where this is incompatible with other uses.

The prairie dog ecosystem is home to
numerous native plant and animal species
including the black-footed ferret, swift fox,
burrowing owl, ferruginous hawk and mountain
plover. The prairie dog is truly a "keystone"
species, providing food, shelter and high-quality
forage for a variety of grassland creatures.

Grassland Management in KSTall Grass on Private
Land
  • Less than 5 of original tallgrass prairie
    remains.
  • Prior to settlement, Iowa had almost twice as
    much tallgrass prairie as KS. Today, only .01
    of Iowas historic total remains.
  • 86 of the historic tallgrass is in KANSAS.
  • Greenwood County has more native prairie than any
    other county - 500,000 acres.

Top Five Threats to the Tallgrass Prairie in
Kansas
  • Invasive species including fire suppression
    species and noxious weeds.

Junipers, Senicia lespediza and other invasive
species.

2. Fragmentation
  • Destruction of wildlife corridors
  • Insufficient habitat for prairie chickens and
    other wildlife.

11
3. Lack of incentives
  • Lack of private, state, or federal financial
    incentives to manage Tallgrass Prairie in a
    sustainable manner.

12
4. Negative Profitability in Agriculture
  • Sell offs to developers
  • Overgrazing in hope of more income.
  • Inappropriate conversion to cropland.

5. Loss of grassland diversity
  • Loss of native speciation and the associated
    social, fiscal, and biological implications.

Coalition building
  • Agencies, individuals and organizations such as
    Kansas Livestock Association, Kansas Farm
    Bureau, The Nature Conservancy, Kansas Department
    of Wildlife and Parks, Wildlife Management
    Institute, and numerous others have all agreed
    that when they walk in the door to a TLA
    meeting, hats, egos and titles are hung at the
    door. All opinions are treated equally. The group
    agreed to discard those issues that appear
    unsolvable and work positively on those that
    appear solvable.
  • Goals are beginning to blend into reality.
    Collectively our goal is to do whatever possible
    to fiscally, socially and environmentally to
    preserve the ranching communities of Kansas.
