    the united states
department of agriculture has a program called wildlife services. its job is to
help protect agricultural and other resources. often that means helping farmers
deal with unwelcome visitors. this organization has experts from different
fields and it has set up thousands of inquiry centers all over the country
where farmer can explain their difficulty and get practical help.

    one example from wildlife
services of its work involved a farmer in washington state in the pacific
northwest. several years ago, thousands of canada geese landed on his fields.
the geese began to eat his carrot crop. biologists from the program suggested
that the farmer use noise-making devices and other measures to scare the large
birds away. these efforts succeeded, which made the farmer quite happy.
wildlife services also has a livestock protection program. the program just
offers suggestions to keep those unwelcome visitors away instead of killing
them. the wildlife services program is part of the animal and plant health
inspection service, or aphis. aphis offers some suggestions of ways to keep
away predators. for example, try to keep food and water safe from wildlife. fences
may help keep out wolves, especially if the fences are at least two meters
high.
