Regenerative Land Management:
Restoring Nature's Balance
By Sonia Myrick and Richard J. Dolesh

ncreasingly, park and recreation agencies across the country are hearing from community members concerned about the use of pesticides
and herbicides in their local parks. They want these products banned,
particularly the use of Roundup, because studies have shown that
some of these herbicides are " probably carcinogenic to humans. "
agriculture, according to the Environmental Working Group. However, a number of credible studies
are documenting a possible link between glysophate and a number of
severe health problems, including
cancer, according to the World
Health Organization. Public concern is reaching unprecedented
levels about the safety of these pesticides and herbicides.

Glysophate, the active ingredient in Roundup, was introduced to
the consumer market in the 1970s
as a broad-spectrum herbicide. Its
effectiveness at killing weeds and
grass is unparalleled and, if applied
correctly, makes the task of maintaining weed-free lawns, plant beds
and agricultural fields much less
labor intensive. In fact, Roundup
is the most heavily applied weed
killer in the history of chemical

cently sat down with Merrie Talley, PLA, LEED, principal of Talley Landscape Architects, Inc.,
to learn from her about a method
she's spent the past 10 years learning how to do and that she calls
" regenerative land management "
(RLM). Following is an excerpt of
that conversation:
P&R: People across the country
and around the world are calling
for the removal of one of the
most effective weed-killing
products. What do you say to
those who wonder what they
would use instead?
Merrie Talley: I have two answers
to that: First, it really puts the onus
on us as [landscape] designers to
think in terms of what kind of
plant communities we can grow.
That's part of the reason to plant
native species. They will thrive
in the climate they developed in.
We've had to over use weed killers
and synthetic fertilizers when we
try to plant exotic plants, because
they're not thriving, necessarily, in
a non-native place or they take over
and become invasives.
Finding plant communities that
fit the landscape is one challenge
and then there are many less unwelcome plants, called weeds, to
manage.
The next challenge is educating

The lush landscape of Houston's Mandolin Gardens Park, a former detention
basin, is a chemical-free, biologically
diverse functioning ecosystem.
