REVEGETATION PROCEDURES
Three broad types of seeding techniques have been tried in the
Peace River coalfield. These are broadcast seeding, harrowing
after broadcast seeding, and hydroseeding.
Broadcast seeding is the most common method used, consisting of
scattering
seed on the surface of the ground.
Broadcast seeding without f e r t i l i z e r applications has resulted in
satisfactory growth at most sites below the treeline. Above treeline,
this method of seed application has generally resulted in
poor growth, but this failure may be attributed to lack of f e r t i l i z e r
rather than seeding technique. Results of piofc trials above treeline
indicate that f e r t i l i z e r applications must accompany seeding for
successful growth and germination, and that, given adequate ferti
l i z e r , most of the grass species used in seeding programs w i l l
grow
well.
Harrowing and f e r t i l i z i n g a l l disturbed areas above treeline has
been recommended by the Ministry of Mines and Petroleum Resources since
1976. It is too early to see i f methods involving harrowing have been
successful, however, preliminary observations indicate that seed catch
w i l l be largely improved over former broadcasting techniques.
Hydroseeding
was used in an experimental way in the alpine areas of
Bullmoose/Chamberlain. I n i t i a l results indicate favourable growth
over the f i r s t summer and good survival is anticipated next year.
