Vine maple
Acer circinatum
Pursh

Introduction

Vine maple is a long-lived, deciduous shrub or small tree. It commonly occurs along rivers, in forest openings and on recently logged areas. Since it sprouts, it may re-grow in clumps or patches after top damage. Vine maple is a shade-tolerant shrub found in the understory of both early and late successional forest stands. Its foliage is a preferred food of deer and elk, and numerous birds and small mammals feed on the seeds, buds, and flowers. Vine maple is used as an ornamental tree because of its beautiful autumn leaf colours (Uchytil 1989). The first peoples used its hard wood to make a variety of utensils (Turner 1979).

Vine maple occurs throughout the Pacific Northwest. Its range stretches from southwestern British Columbia to northern California along the coast, including Vancouver Island (Little 1976). The area in British Columbia represents less than half of its total range.

Distribution and Protected Areas – from Hamann et.al. 2005

Conservation Status Summary – from Chourmouzis et.al.

No in situ conservation concerns were identified for this species.

Reproduction

Seed crops are annual but irregular (Banerjee et al. 2001). Vine maple produces few seeds and relies primarily on vegetative reproduction by sprouting or layering (Anderson 1969; O’Dea 1995). Plants reproduce from the base of the stem after logging or fire. Occurrence of vine maple in early successional communities is therefore primarily dependent upon its predisturbance distribution (Hubbard 1950). This would imply that the species’ genetic diversity is not usually affected by one cycle of logging. However, Tappeiner and Zasada (1993) reported good seedling emergence for vine maple, especially in thinned stands, implying that under the right light conditions, sexual regeneration does take place.
