We’ve been
dismayed at the amount of Buffel grass we’ve seen this holiday – from Norseman
all the way to Pt. Hedland, and now down to Carnarvon.
Buffel grass
is believed to have been accidentally introduced in the packing of imported
camel saddles from Afghanistan in the 1860’s. Being drought resistant and also
able to withstand heavy grazing, until quite recently it was deliberately
spread throughout the dry inland areas for its value as a stock feed. Now many
environmentalists put Buffel grass in the same category as European Carp and
Cane Toad because of its negative environmental impacts.
Buffel grass
responds vigorously to water, so grows especially strongly along river banks
and roads (where it receives run-off), creating corridors for the spread
of fire. Having a high nitrogen content, it burns very hot, further enabling
the spread and intensity of fires and severely reducing the ability of native
vegetation to recover.
It
aggressively out-competes native grasses and other ground cover plants, creating
a very foreign environment for our native birds, insects and animals – as
though they don't have enough to contend with already!
