2018 Red Alder Management Workshop – Sep. 29th in Kent

A stand of alder trees

Alder needs to be managed differently

Red alder (Alnus rubra) is the most common native hardwood trees in western Washington. This moisture-loving tree is most common in riparian areas near streams and wetlands, where it contributes to high-quality habitat and clean water. Alder is also a valuable timber species that can fetch premium prices for specialty markets. Alder is short-lived, though, and older stands can quickly lose their value, stability, and ecological function, often degenerating into brush patches dominated by invasive species.

Red alder needs to be managed differently than conifer stands. It has different growth traits, site requirements, and spacing needs. Its short life-span means timing is important for harvesting or managing successful natural succession, and this requires advance planning.

 

Alder challenges and opportunities

This workshop will take a comprehensive look at the challenges and opportunities that alder presents to landowners. We will explore management options for different alder stand types, including young, dense thickets and older stands that are falling apart. We will talk about market opportunities for alder and how to recognize and grow high-quality trees. We will also talk about managing natural succession for property owners who don’t want to clear-cut the alder but also don’t want it to become a brush patch.

The workshop will feature classroom sessions in the morning taught by experts in alder ecology, silviculture, and marketing. Topics include:

  • Red alder ecology – growth traits, suitable sites, life history, and ecological role.
  • Management options for over-mature/dying stands, including both harvest and non-harvest options for different property types, and managing understory vegetation that is typically associated with riparian alder sites.
  • Red alder silviculture – Improving existing stands, managing natural regeneration, and growing new alder plantations (this will cover seedling sources, site preparation, planting, spacing, and growing conditions for bottomland and upland sites).
  • Markets for red alder

An afternoon field trip will visit a site to see what a property owner is doing to help transition an overpopulated and weak alder stand to healthier, longer-term forest cover.
