Vancouver Ecological Explorer
This month the Ecological Explorer takes you to a coastal mountain
stream at Lynn Headwaters Regional Park in North Vancouver. You will
see a riparian ecosystem in a young western hemlock forest.
Lynn Headwaters Regional Park
North Vancouver
Riparian stream wetland
- 60 - 100 year-old western hemlock forest
- 1-km or longer return trail
- Allow 2-3 hours on the trails
- Easy walking
- Good year-round may be snowy and icy in winter
Coastal mountain streams change dramatically from dry to wet weather
periods. During dry periods they trickle through and beneath the
stream bed, but in wet periods they become torrents.
This effect can be seen well in Lynn Headwaters Regional Park, managed
by the Greater Vancouver Regional District, in North Vancouver,
open 8:00am-9:00pm daily (closes at dusk in the fall and winter).
The full width of the Lynn Creek stream channel in the park is about
15 metre. During most of the year the stream is about 8 metre wide.
Occasionally in the winter or early spring after a period of heavy
rain and melting snow, it can become a raging torrent, completely
filling the channel.
When you visit, you will most likely see a wide stream channel made
up of large boulders and a small stream flowing down the centre.
On the banks above the boulders, a margin of red alder trees and
salmonberry survives the periodic flooding.
Above the margin is the 60- to 100-year-old western hemlock forest.
Old stumps provide evidence of logging from 100 years ago.
Birds include Steller’s jays, flickers, ravens, chickadees,
kinglets, siskins, wrens, varied thrushes, and hawks. You may also
see black-tailed deer and Douglas squirrels.
Getting there
From the parking lot, walk a short distance north on the Varley
Trail and over a bridge at an old water control structure. Walk
about 0.5 km north on the Lynn Loop Trail to a good viewpoint of
the Lynn Creek stream channel. You can also go south on the Varley
Trail to another bridge across Lynn Creek to make a loop back to
the parking lot (2 km). Light walking shoes are sufficient for this
trail. Picnic facilities, toilets, and public telephones are available.
Get to Lynn Headwaters Regional Park by bus, car, or taxi to North
Vancouver. Take the Upper Levels Highway (Hwy. 1) to Exit 19. This
is about 6 km east of the link to the Lions Gate Bridge, and 4 km
west of the Ironworkers Memorial Bridge. From Exit 19 go 3.5 km
north up Lynn Valley Road to the park entrance and a further 1 km
to the parking lot. You can also get to the park by the Sea Bus
across Burrard Inlet to North Vancouver, and then the #228 bus to
the park entrance. For more information call Greater Vancouver Regional
District Parks, West Area office, at (604) 224-5739.

Centre.
