? Prepare 10 sand paper cards (5 cm x 5 cm) per field and 10 predator exclusion cages with 1 cm squared metal net to avoid predation by mammals and birds.
? Glue 10 poppy seeds on each card and place each card within an exclusion cage.
Data collection
? Collect data twice during the crop cycle, preferably in spring for winter cereals (avoiding drought periods).
? Define two transects in the monitored field. Place 5 seed cards with exclusion cage along each transect and nail them into the floor (day D).
? Remove them after 4 days of exposure to predators
? Count the remaining seeds on each card.},
