Paving roads can increase weed invasions
...Roads are a big part of the problem: for instance, vehicles
can transport non-native seeds into uninfested areas, and clearing land during road construction gives weed seeds a place to become established. Intuitively, it makes sense that improved roads would spread weeds more than primitive roads because the ...
