2.2.0 Streams and Forests

2.2.1 Background

       Burnaby Mountain has a mix of homogeneous and heterogeneous vegetation in terms of age and species distributed over the mountain top (BMDC, 1996:20). The northeast region within the Ring Road is dominated by diverse mixed deciduous and coniferous forest. This forest type is highest in plant diversity and structural heterogeneity, with coarse woody debris, snags and diverse herbaceous layers (Stewart Environmental, 1996).

       The northeast area is also home to the greatest concentration of significant trees. These trees are classified according to species type (Bigleaf Maple, Western Hemlock, Western Red Cedar and Red Alder), and tree age (size) (ibid, 1996). This area also serves as an important wildlife movement corridor, especially for deer (ibid, 1996).

       A number of major streams have their headwaters on Burnaby Mountain, including the major fish-bearing streams, Stoney Creek and Eagle River. Naheeno Park is an area of mixed deciduous and coniferous forest recognized as being ecologically significant (City of Burnaby, 1996). A number of stands of significant trees are located here. The dominant features of this area are the headwaters and tributaries of Eagle River and Silver Creek. The ravine habitats, including riparian zones, formed by these streams are natural wildlife movement corridors. Eagle River is salmonid bearing, whereas Silver Creek is not. Eagle River to the west, and the westward tributary of Silver Creek will need special consideration to prevent hydraulic, sediment and debris loading as adjacent development proceeds (Stewart Environmental, 1996).
