- Maplewood Creek is part of the Seymour River system
- Originates above Mount Seymour Parkway. Groundwater from upslope terraces discharges through several springs and seepages and supports a network of wetlands that form the headwaters.
- Status: Endangered – due to riparian removal, urbanization, culverting and degraded water quality.
- Before mid-1800’s -North Vancouver District was inhabited by Coast Salish peoples.
- 1860’s - First significant non-native settlement began.
- Late 1800’s to early 1900’s – Trees over 90 m high and 11 m in circumference were logged. Windridge area extensively logged around 1910.
- 1865 – Hugh Barr purchases first land east of Seymor River beginning first European settlement.
- 1930 - Construction of the Dollarton Highway encourages further settlement of the Maplewood neighbourhood.
- 1950s - Port oriented industry commenced with the introduction of the first chemical plant in Maplewood.
- 1987 – Ammonia runoff from duck pond results in high mortality of juvenile coho.
- 1990 – First return of chum (15) following enhancement efforts.
- Fish – chum and coho salmon. Documented spawning south of Seymour Parkway. Unconfirmed sightings north of Parkway.
- Wildlife: bear, bobcat, coyote, raccoon and red fox have been recently seen by residents. Also, deer, moles, shrews, marten, weasel, mink, turtles, lizards, snakes are believed to inhabit area.
- Diverse bird population: 80 species (Tera).
- Vegetation: Coastal Western Hemlock Zone
- Maplewood Farm, District of North Vancouver
- Maplewood Community School
- Seymour River floodplain
- Stream has been classified as endangered due to impacts (FRAP).
- Significant loss of riparian vegetation along more than 50% of the fish frequented length of the stream (FRAP). Loss of vegetation due to development and removal by land owners.
- Water quality – Significant problems including problems with ammonia, sediments from erosion and development near the creek (FRAP), and contaminants from stormwater and spills into storm drains.3 storm drains discharge into creek. High nutrient run-off from equestrian centre, duck pond, and Maplewood Farm.
- Urbanization in the watershed has significantly affected the stream basin (FRAP)
- Channelization, armourization, or dyking of over 50% of the fish frequented length of the stream (FRAP)
- Aquatic system considered highly valuable and highly sensitive to development (Triton).
- Creek was diverted and recreated to build Mount Seymour Parkway.
- Groundwater discharge at the area of Hogan’s Pools supports a wetland and the Maplewood stream system and associated fishery which are highly sensitive to development (Triton, 1993).

Recommendations and Suggested Actions
- Protect the highly sensitive aquatic habitat of Hogan’s Pools as park (Triton, 1993).
- Maintain the continuous native riparian conduit from Seymour River headwaters to Hogan’s Pool area provides wildlife habitat and corridors (Triton).
- Maintenance of habitat corridors requires cooperative planning with other property owners between Hogan’s Pools and the Upper Seymour watershed (Triton).
