Green Alder
Water Sedge

Green Alder is a cold hardy, native shrub. It is often planted on infertile sites so it can fix nitrogen from the air and improve the soil quality.

Green Alder is known for its smooth grey bark and attractive shiny green leaves; it is commonly used in reclamation.

Water Sedge is a waterside grass which grows an extensive horizontal root system. This prevents erosion and allows it to grow back after being eaten.

Water sedge is grazed by many animals including cattle, sheep, horses and waterfowl. Animals choose Water Sedge for forage later in the year as it stays green longer than other plants, requiring you to buy feed for less of the year.
