This week in #Norrestry (my Forest Ecology & Mgmt course): We wrapped up the lab portion with presentations by small groups on their projects exploring forest ecology questions using big datasets (USFS FIA). We heard about regen in urban vs rural NY, the effects of hurricane Katrina in LA, (1 of 2)

This week in #Norrestry (my Forest Ecology & Mgmt course): Students selected a study tree months ago & are now telling that tree's story, Part III: Today we learned about the bald cypress swamp habitat, the fashion changes that trees have witnessed, unusual life history traits, and more!

This week in #Norrestry (my Forest Ecology & Mgmt course): We also had a great guest lecture by my friend Dr. Autumn Sabo who presented on the threats of deer to forests and the forest understory and how it varies with different soil conditions.

This week in #Norrestry (my Forest Ecology & Mgmt course): Students selected a study tree months ago & are now telling that tree's story, Part II: Wednesday's stories told about trees as habitats, unique life history traits and growth patterns, construction threats & benefits, and more!

This week in #Norrestry (my Forest Ecology & Mgmt course): Students selected a study tree months ago & are now telling that tree's story. Today's stories focused on why trees grow the way they do, history they've witnessed, threats to the tree/forest, & the food web that trees contribute to

#Norrestry lab this week (my Forest Eco & Mgmt course), we continued assessing campus landscape trees for our Tree Campus application. We surveyed our original campus property (286 trees). We also crunched data from our previous survey of >300 trees. 94% were rated of good or fair overall health.

#Norrestry lab today (my Forest Eco & Mgmt course), we're assessing our campus landscape trees for our Tree Campus USA application. A previous class drafted the application focusing on the nearly 31 ha of campus forest. Coincidentally they're planting dozens more trees around our new construction.

Forest nutrients day in #Norrestry (my Forest Eco & Mgmt course), so of course notes are sketch-based

This week in #Norrestry class (my Forest Eco & Mgmt course), we visited our local Oregon Ridge Park to check out some of its forest and forest management. Like most regional forests, the forest is threatened by deer and invasive plants & pests. #forestry 1/2

This week in #Norrestry class (my Forest Eco & Mgmt course), we finished forest plot surveys at local Irvine Nature Center. We're collecting data to describe the forest composition and structure, focusing on deer browse, to understand early conditions as they implement a deer harvesting program.

The #Norrestry class (my Forest Eco & Mgmt course) has a new campus Witness Tree post exploring the tree-related microhabitats (TreMs) of the tree. Of course, we had to climb the tree to get the best views. www.instagram.com/stevensonwit...

This was found…" Towering high overhead rests our northern red oak's sprawling canopy, covering an average of 79.9% of the sky above. This was found using a hemispherical lens (as seen in pictures.) These images were then processed through Gap Light Analyzer, a program to calculate canopy cover percentage. As you can imagine, this large canopy cover causes quite the lack of light available for any plants below, but just how little light is there? Using an AccuPAR LP-80, the light available in the understory was measured at an average PAR (photosynthetically active radiation) of 41.5 µmol/m²/s. For comparison, a nearby open field measured PAR of 1402 µmol/m²/s! This means that the plants below our witness tree have very little light to work with. Regardless of that, many young trees are powering through and manage to keep growing.This forest community surrounding our focus tree has a variety of both old and young trees, our tree likely being one of the oldest. As older trees die off, gaps in the canopy appear, allowing the younger and shorter cohorts to have more access to light. These cohorts not only must tolerate the shady understory, but manage to thrive in it. From just these few light related factors alone, we can begin to see how this community came to be what we see today. Hemispherical canopy images taken at the witness tree's canopy edge in each of the 4 cardinal directions.

The third #Norrestry #WitnessTree post is up! One of our students describes the health status of our tree.

Last two weeks in #Norrestry (my Forest Eco & Mgmt course) lab, learning to measure trees and forests including canopy cover, tree sizes (diameter, height, volume), forest volume, and calculating tree value.

The second #Norrestry #WitnessTree post has dropped! One of our students describes the human history of our tree's surroundings.
