 Clean
Ups
River Works volunteers conducted four clean ups this year at Fraser
River Park, removing a total of 110y³of wood debris. That
is equal to almost three full dumpsters of wood! Removing 20y³
resulted in a 10% increase in marsh vegetation in our June clean
up. The plants will definitely have plenty room to grow after
all the clean ups this past year! A great big thank-you to BC
Regiment Cadets, The Young Biologist's Club, and Vancouver Aquarium
volunteers for all your hard work.
Plant Survivability
 River
Works volunteers headed out to determine the survivability of
the native plant species that we planted in November of 1998.
The majority of the plants are in fair to excellent condition.
The survey was done on a hot, dry, summer day, which potentially
effected the condition of the plants. Come autumn the plants may
appear healthier.
Non-native
Plant Species Removal
River Works volunteers worked relentlessly at removing non-native
plant species from Fraser River Park this summer. Scratches from
blackberry, heat and the famous Fraser River Park fire ants weren't
enough to stop this group. This summer 7 large garbage bags of
purple loosestrife were removed from this site. Susan Heaslip,
seasoned River Works volunteer, noticed there was much less purple
loosestrife at the site this year. An area equal to 0.6m³
scotch broom and himalayan black berry was removed.
Vegetation Surveys
Conducting a plant survey requires lots of patience, especially
on a hot summer day, but thanks to a small groupof hard-working
volunteers the plants growing in the marsh were all identified.
Grasses were found to dominate at FraserRiver Park. The common
rush was the second most abundant plant. Plants in the other category
included:lyngby's sedge, meadow barley,lesser spearmint,
commonhorsetail, spring bank clover, large headed sedge, purselane,
hairy cat's ear, american vetch, and curved wood rush.
