The Peace River (Northeast) Coal Block is located in the Rocky Mountain foothills, extending a distance of 240 kilometres from Williston Lake to the Alberta border (Figure 1). This area has received extensive exploration activity over the last few years, with a promise of further development in the future. In general, exploration work has taken place in high elevation alpine and subalpine regions where revegetation is difficult and disturbances are highly visible.

Under Section 8 of the Coal Mines Regulation Act it is the responsibility of the Ministry of Energy, Mines and Petroleum Resources to control reclamation of exploration disturbances. Part of these duties have involved prescribing methods of revegetation. In the Peace River Coal Block it became rapidly apparent that the standard forestry mix applied without fertilizer was not adequate to revegetate disturbances above the treeline. During 1976, 1977 and 1978 a series of test plots were established to allow recommendations to be made on the basis of sound data.


The objectives of these test plots were:

a) To test species germination, growth and survival under a variety of conditions.

b) To test fertilizer requirements.

c) To test the effect of different seeding rates.

d) To test the use of seed coated with micronutrients.

e) To test the difference between spring and fall seeding.
