The Aleza Lake Research Forest maintains several long-term research sites and datasets. These datasets are available to faculty, student, and government researchers and instuctors who require long-term data. Additional information can also be collected from the existing field sites. If you are interested in using the data or research sites contact our staff.
Two periods of data collection are available: 1953 to 1980 at the former BC Forest Service Ranger Station just out side of the northern ALRF boundary; and two climate stations installed in 1993 and monitored until the present, one at a clearcut site and one within a stand of old growth forest. The maintenance of the climate station field site and online database are funded by the ALRF Society and the BC Forest Science Program. The datasets are available through an online climate database.
Partial Cut Experimental Plots
Over one hundred plots were established by the BC Forest Service between 1947 and 1961 to monitor the effects of various partial cutting prescriptions on spruce/sub alpine fir forests.
Growth and Yield Plots
These BC Forest Servcies plots were established between 1926 and 1934 have been continuously re-measured ever since (most recently in 2012).
Progeny and Provenance Trials
Both these trials were established by BC Forest Service and are still maintained byt the Tree Improvement Branch. The progeny trial was established in 1972 and is a replicated trial with over 11,000 sample trees. The provenance trial was established in 1966 with over 1100 seedlings planted from 40 difference provenances to test the performance of white and Englemann spruce.

ALRF Species Trials
The Aleza Lake Lake Research Forest Society has established several replicated trails and smaller demonstration sites to monitor the growth of various planted tree speces at ALRF. These include western red cedar, larch, and Douglas fir.
