Alder kick-starts the successional processes that lead to productive forests…
…later successional conifers establish naturally under the canopy of pioneering vegetation…
… but the dense cover of seeded grasses and legumes out-competes the alder unless the alder can form a closed canopy.
What are the processes that help the ecosystem shift from a planted Alder / Grass stand…
…to an Alder / Salmonberry / conifer stand?
