As we hide porous surfaces with impervious structures—commercial constructions, parking plenty, roads, and houses—finding locations for rainwater and snowmelt to soak in turns into tougher.

If it lands in a polyculture its 19 progress is barred on every hand by plants which it cannot infect and serious damage is unlikely. There are also some plants which put out chemicals which boost the growth of their neighbours. For example, corncockle growing amongst wheat can increase the yield of the crop by up to five percent.

There are doubts about how many of the seeds are still alive in many gene banks.
