Description

Three recipients of our chapter's research grants share their research and findings:

Tree Mortality and Regeneration Across Competitive and Geographic Gradients in Northern California
To compare tree mortality and natural regeneration patterns in the heavily timbered, diverse forests of northern California before, during, and after the 2012-2015 extreme drought Sophia Lemmo measured and cored trees in 54 plots. Her preliminary results suggest that tree mortality was lower in drier habitats, when compared to areas that had higher average annual precipitation. Sugar Pine and Western White Pine mortality rates were approximately double those of Shasta Fir and White Fir, which were 4-5 times that of Brewer's Spruce. In the understory, fir saplings were more than 15 times as common as pine saplings. The mean age of regeneration was 33 yrs old, and their height averaged 36 cm (14 in.). Managing these forests for diversity and production requires understanding each tree species' demographics
Plant-microbiota interactions in Darlingtonia californica: microbial communities facilitating prey item breakdown and nutrient acquisition
Megan Teigen sampled the liquid in the pitchers of many California Pitcher Plants in three different fens and studied the diversity of bacteria there and their role in digesting the prey captured by this carnivorous plant.

Macrolichen Inventory of Horse Mountain Botanical Area, Six Rivers National Forest.
In the dramatic, botanically and geologically rich setting of the Horse Mountain Botanical Area Sarah Norvell focused on the lichens, documenting all species of macrolichens she encountered in hopes of creating a species checklist for Six Rivers National Forest.

Evening Programs are free, public presentations on the second Wednesday of each month, September through May. During covid restrictions and for non-local speakers programs will be held via Zoom, at 7:30 p.m.
