CAN BE FOUND IN:

Scrub Birch

Betula glandulosa 

Appearance

Also known as bog birch, swamp birch and dwarf birch, scrub birch is a shrub with resin-filled wart-like glands on its twigs and nearly circular, deciduous and leathery leaves. Its flowers are male and female catkins up to 3 centimetres long. 

Range & Habitat

Scrub birch is native to the northern part of Canada and Greenland and to higher elevations in areas as far south as California. At lower elevations, it’s usually found near wet or boggy areas while at higher elevations it is found in drier areas. 

Reciprocal Relationships

Scrub birch trees are biodiversity enhancers in their areas. They are a pioneer species that can grow back after disturbances, creating more space for understory plants to grow. They have shallow, spreading roots, that can help stabilize the soil and purify water.  

When the female catkins are pollinated, they form small nutlets that each contain a single seed and drop when they are ripe in the autumn. Although it is not particularly nutritious, moose and snowshoe hare graze on the leaves and twigs of the scrub birch, while ruffed grouse eat the buds and seeds.
