Table 2 Hierarchy of exclusion for filtering the results of the database searches
From: Systematic review of situational prevention methods for crime against species
THEME | The title/abstract of the paper must clearly identify its relevance to the prevention of crime against species (e.g. poaching, theft, illegal trade) |
GEOGRAPHY | The title/abstract must not indicate a location that is exclusively urban (e.g. urban area, town, cities). If the title/abstract did not specifically indicate a location it was progressed to the next stage |
INTERVENTION | The title/abstract must have referred to specific interventions for the situational prevention of crime against species |
SPECIES | Aquatic (e.g. coral, fish) or microscopic species (e.g. protozoa, algae) were excluded. Humans did not qualify as targets of crime in this review |
