But of course. We never had decent hedgerows, and I wish we did; even
where fields are crossed with drainage ditches they are kept weed free,
which means that they are colonized, not by choice natives, but by a low
class of adventitious weeds, mostly foreign.
In England, hedgerows can be dated by the number of species of
shrub and tree that have added themselves to the original hawthorn or
whatever. There's a nifty little formula. Here in the states, things
change so quickly that even the hedgerows aren't permanent.
While farmers do indeed use pesticides, and the states also use
them to control invasive insects (gypsy moths for instance, and
Mediterranean fruit flies) I would say that our main problem is urban
and suburban sprawl, and the chemicals used by householders in order to
maintain green lawns in the face of overwehlming adversity.
This is, of course, the fault of the British who indoctrinated
us into the notion that "nice people" have grassy lawns. Actually,
unless you have sheep or small children, a lawn is a foolish waste of
The existance of the monocultures here: people, cats and dogs
instead of an assortment of mammals of various sizes; grassy lawns and
exotic shrubs and trees instead of natives ... has put tremendous
pressure on ecosystems. We still suffer from the delusion that Nature is
out to get us, and that cleanliness is next to godliness. A nation of
telephone sanitizers. We're working on this though.
We are hampered by the fact that Nature actually is out to get
us, and occasionally reminds us of this with a spot of bubonic plague,
or Hanta virus or whatever.
My neighborhood is promoting greenbelts, which are an
elaboration on the hedgerows principle. The developers are winning,
because they have the money and the time.
