Media coverage of the controversy surrounding the use of certain non-native feedstocks for bioenergy is as pervasive as invasiveness itself. Plants such as giant reed (Arundo donax) and elephant grass (Pennisetum purpureum) are known to be weedy or invasive in natural habitats; the concern lies in their ability to spread propagules into natural habitats outside intended areas.

The consequences of plowing farm ground are so serious, John Baker says the implements should have warnings on them similar to cigarettes. We’ve always argued here at No-Till Farmer that tillage is addictive, especially when it’s recreational tillage that accomplishes little or nothing.

With perennial plants, including many invasive plant species, things change in the fall, because instead of just producing seed, plants begin storing resources underground.
