Spatial Infestations and Variability

why is it important to assess the spatial variability?

identify problematic “hot-spots”

identify areas/weeds with high potential for invasion (early detection)

• hot spots, less dense canopy are places where species invade

spaitial inf;uence on invasion potential

spatial distributions can affect the “lag phase” of a weed invasion

multiple small sources (rather than one large one) will allow species to more rapidly enter the “log phase” - not competing with itsself

spatial preference of invading weeds?

spatial distribution of the ecosystem?
