• What differentiates site modification from site
  conditioning?
• Site modification usually entails a structural
  solution to providing a desired condition,
  service, etc.
• Site conditioning depends more on the autogenic
  capabilities of a biological community.

Site conditioning can include

• Seedbed improvement
• Preparatory crops/stubble
• Mulch
• Creation of shade
• Addition of topsoil on stripped sites
• Building of soil OM by growing vegetation that
  can tolerate a degraded site
