New ALRF Trail Maps!

Cabin fever? Prepare to get outdoors this spring at the Aleza Lake Research Forest…

ALRFS just published two new trail maps on our Maps page. We are also  preparing  a trail brochure  which will have  maps and more information about how to get to the Research Forest and what you can find on the trails…so stay tuned!

Not interested in going out for a walk on your own? Arrange for a guided tour for your group! For more information see our Education page.

New Publication on Lichen Research

Congratulations to Jocelyn Campbell (UBC PhD Candidate) and her co-authors  on their recent publication in the Canadian Journal of Forest Research. The research took place at various locations within  Aleza Lake Research Forest and surrounding ecosystems.

The paper describes a study on cyanolichens, a type of lichen that grows in wet climates and old forest conditions. Cyanolichens that grow on trees are picky about where they live. For example, this paper cites other studies that have shown cyanolichens are more abundant and diverse on sub-alpine fir trees (Abies lasiocaropa) then they are on hybrid spruce (Picea glauca x englemanii). In fact this paper shows that one of the places that cynolichens are happiest is on conifer saplings that grow under aspen (Populus tremuloides)  or cottonwood (Populus trichocarpa). This  unexplainable association was even stronger in study sites where conditions for cyanolichens were marginal, including those at ALRF.

Update on Larch and Cedar seedlings


As mentioned in the previous blog, we have teamed up with the UNBC Enhanced Forestry Lab to grow some larch and cedar seedlings for planting out on the research forest.

Seeds were planted just before Christmas and it was the larch seedlings which popped to the surface first.   It has been and still is very noticeable the difference in growth between the two species.

Talking with Steve Storch (Greenhouse Curator) last week, about the cedar seedlings in particular, he commented that the cedar seedlings appeared to germinate quicker in the conventional gravel grit compared to seeds covered with “styrogrit” (made from recycled styroblocks).   Steve indicated that the seeds covered with styrogrit seemed   to be  about 2 weeks slower  than those covered with the gravel grit. He further explained that this would intuitively make sense since the styrogrit is white and reflects heat, while the gravel grit is grey and darkens up even more when wet. this likely leads to a higher temperature near the seed which is good for seed germination in general. The white reflective grit may perform better when the seedlings are bigger when we will be more concerned with how fast the blocks dry out.

Styrogrit was used with the larch seeds, on all the blocks, so there isn’t a growth comparison for that species.
