Source populations for seed production for trees & shrubs

What do you see? The map shows populations of trees and shrubs that represent a certain genetic value for these species in the Netherlands. The map shows the location of populations that serve as an object for seed extraction or production of propagating material for forest and landscape construction. What’s the value? The populations represent a certain economic value and/or ecological value. The propagating material harvested from these populations has either a production objective (production of high-quality wood) or ecological objective (cultivative material represents an ecological value, also called autochonic plant material) Who is this important to? Managers of nature, forest and landscape plants, growers.
