COMPLEXITY of a forest

Implications for ADAPTATION and RESILIENCE potential Role of BIODIVERSITY

Typical structure of primary forest, with relatively open canopy (Pilsko, Slovakia)

Extream yet wide spread form of spruce plantation. Maximum stock vs minimum resilience, stability, biodiversity and aesthetics. (Collapse due tu climate change?)

Complex/Intact ecosystems HAVE GREATER CAPABILITY TO OVERCOME ENVIRONMENTAL STRESSORS, including changes to climate, than simplified (degraded) ones as they have inherent properties that enable them to maximize their adaptive capacity.

  • more above- and belowground carbon stored
  • more faunal complexity (helps carbon stoarage and

sequestretion)

  • major carbon sequestration (soil, biomass, necromass)
  • regulating local and regional weather regime
  • generation of rain and reduced risks of drought
  • ensuring hydrological services
  • conserving biodiversity
  • consistently higher number of forest-dependent species
  • sustain important large scale ecological processes
  • higher functional diversity
  • higher intra-speciffic genetic dversity
  • higher chance for dispersal or retreating refugia
  • provision of key pollination and dispersal processes
  • human health benefits
  • and BEAUTY
