Throughout U.S. history, such altruists have

Nearly 190 years ago, in his book Democracy in

community-based leaders and groups. He saw
them as local democracies that set social mores
and helped ward off tyranny.
During the past five years, National Geo-

people living in downtown Browning, Mon-

Reservation—face the challenges of poverty,
drug addiction, and suicide.
Those problems have plagued a community
where, in the words of the late chief Earl Old Per-
son, some “strive to come back from Western
influence,” while others try to embrace it.
In an effort to link younger generations with
their roots, Blackfeet leaders take children on
field trips throughout the sacred land to teach
them about the ancestors who lived there and
the value in keeping it free of development. The
plants, the wildlife, and the soil all have ties to
the tribe’s cultural traditions.

against drilling leases.
“It’s been a long road—35 years or so—but
there are no wells up there,” Murray says. “There
will never be drilling in Badger-Two Medicine.”
The story of the Blackfeet and Badger-Two
Medicine is about protecting one of America’s
Native lands—a place at the genesis of Indige-
nous history and creation stories, the foundation
of every value in Blackfeet culture and commu-
nity: family, education, identity, survival.
The Blackfeet see the land as their keeper.
It’s where they learned about buffalo running
and pack building from the wolves and got their
songs from the birds. The Blackfeet way of life is
imbued with the spirit of the land. One without
the other means both cease to exist in the same
way. Leaders are passing on those lessons, with
increasing urgency, to Blackfeet in Browning.
Each July, the nation’s traditions are honored
at the North American Indian Days celebration.
The annual parade “brings our traditions back
to people living in the downtown,” says Darrell
DeRoche, a Blackfeet youth mentor. “There
are some people here who have never been to
Badger-Two. We are doing our best to change
that, bring our traditions here, and bring people
to the land. To keep our history strong.”

Outside of a 33-foot zone surrounding those veg-

Dispersed retention is better for soil health,
Grayston says, because it typically preserves a
tree every 46 to 52 feet, which allows their roots
and respective zones of influence to overlap,
providing carbon to microbes throughout the
forest floor.
Dispersed retention and other selective meth-
ods of harvesting are becoming more common
in some regions of the world, but clear-cutting is
still widely practiced in North America because
it is more efficient, costs less, and requires less
complicated machinery. Aggregated retention
usually is favored over dispersed retention for
similar reasons.
“We need to reconsider forestry practices,”
says environmental microbiologist Petr Baldrian
of the Czech Academy of Sciences’ Institute of
Microbiology. “Clear-cutting is economical, but
it comes at a huge cost to the state of the soil.
We need to find a balance between the needs of
industry and the needs of the forest.”

She’s thrilled by the grand mystery of
all that remains to be discovered, which is essen-
tially why she chose to study microscopic life
in the first place. “We’ve made a lot of strides,”
Grayston says, “but we still don’t know who is
actually active at certain times and which spe-
cific organisms are really important for different
processes in the soil.”
At the same time, she is alarmed by the con-
tinued decline of forests in many parts of the
world because of overharvesting, poor land man-
agement, and the stresses of climate change.
