Macro-gardens are classical provenance trials where seeds are grown to seedlings in the ideal and controlled environment of a nursery. After two years, seedlings are transplanted to an open-air test site and monitored for 5 years.
Types of macro-gardens
One species, small
1 species, 5 provenances, 100 seedlings per provenance (10 families with 10 offspring each).
Total: 500 seedlings distributed over an area of ~125 m2.
Two species, small
2 species, 5 provenances each, 100 seedlings per provenance (10 families with 10 offspring each).
Total: 1000 seedlings distributed over an area of ~250 m2.
