Class: Herbology (Professor Fernfoot)
Pairs with: the unit on trees and bark. The tree lessons live on the Herbology class page; this trip takes them to standing timber.
Trip type: Arboretum / Park / Woodland
Where it works: any arboretum, park, woodland, or tree-lined street. Arboreta label their trees, but any three honest trees will do. Free, and best in winter when the leaves are gone and bark carries the whole introduction, though it works in any season. Paper and a crayon are the only kit.
Why we're going: The tree lessons teach identification from bark: ridges, plates, peeling ribbons, thorns, colour. On a page, bark is a photograph. Standing in front of the tree, it is evidence you can touch, compare, and test against the label. This trip takes the unit out to standing timber and makes the bark argue its own case.
The mission: Bark stays all year, and bark is how a tree introduces itself in winter. Your mission is to take bark rubbings of three different trees, identify each one from the evidence, and note which of them people once had uses for. Rubbings first, names second: let the bark make its case. You will come home with three rubbings, each labeled with your identification and the feature that clinched it.
What to record:
Three bark rubbings, each labeled with your identification of the tree.
For each, the feature that clinched it: ridges, plates, peeling ribbons, thorns, color.
One of your trees and the use people once had for it, reported as history: what was once made or taken from it.
Whether your identification matched the label, and what fooled you if it did not.
How it runs:
Level One — At Home: Your own street is a small arboretum that forgot to charge admission. Take your three rubbings from the nearest trees on public ground: your yard, your street, the corner park. Identify them by bark, buds, and shape, from a field guide or app.
Level Two — In Person: Go where trees are labeled: an arboretum, a park with a tree trail. Rub first, identify from bark alone, then walk to the label and mark your own work. Three correct from bark evidence is a fine score; two and an instructive miss is a better education.
Picture ideas for the gallery:
A finished rubbing held up against the bark it came from.
Bark close up: the ridges, plates, or ribbons that clinched an identification.
The whole tree, so the gallery sees what the bark belongs to.
Your three rubbings side by side, three introductions in a row.
Etiquette & safety: Rub gently: paper flat on the bark, side of a crayon, no pins, nothing driven into the trunk. Never peel bark, not even a loose-looking flake; bark is the tree's skin, and a ring of it removed can kill the tree outright. Take the rubbing, leave the bark; no tree here gets tasted, tapped, or used.
Field Report: Which of your three trees could you now recognize from across a field, and by what sign? File your report in the comments below: where you went, what you found, and one thing that surprised you. Photographs go to the Field Trip Gallery through the form on the Field Trip Office page, with the town and country where they were taken.
