QuestionHow high is the level of ecological connectivity of this natural resource system?
Select Options1 Low, 2 Medium, 3 High
ImportanceEcological connectivity can enhance resilience by facilitating recovery and renewal in systems, for example the dispersal of seeds or the spread of pollinators between habitats. Over-connectivity can, however, mean that disturbance events cascade rapidly through a system causing system collapse, for example the global impact of pollution is exacerbated by the high connectivity of the atmosphere (i.e. pollution does not stay in the area where it is released) . Some degree of modularity to "contain disturbances by compartmentalizing social-ecological systems" is beneficial for resilience (Carpenter et al. 2012)  

Internal connectivity is the manner and extent to which populations and species (e.g., eggs, larvae, juveniles, adults) or impacts (e.g., pollution spread through water flow) can disperse, migrate or interact across ecological sub-systems (e.g., patches and habitats).
