Chapter 7 Forest Etiquette

features of a mature well-formed deciduous (37)

• in youth

• narrow branches

• extend away from trunk

• die off

• sealed with new bark

• smooth column

• straight trunk

• regular arrangement of wood fibers

• long and smooth

• roots stretch out evenly in all directions

• reach down into earth under tree

• top

• symmetrical crown

• strong branches

• angling upward

same for conifers except

• topmost branches horizontal (or bent slightly downward)

STABILITY

• windstorm can tear at base of trunk with a force of 220 tons (38)

problematic tree shapes

• curved trunk

• difficult to just stand there (38)

• weight of crown not evenly distributed over trunk diameter

• tree reinforces wood in that area

• dark areas in growth rings

• less air and more wood

• forked trees

• each have their own crown

• both swing back and forth in different directions (39)

• U shaped

• tree can make it

• V shaped

• fork breaks at narrowest point

• thick bulges of wood to try and prevent further damage

• bacteria blackened liquid constantly seeps from wood

• water gathers = rot

• banana shaped trunks

• lower part sticks out at an angle (40)

• due to snow or earth slide

trees grow only from the tip (40) what does that mean exactly? tip? tips

conifers grow straight or not at all (41)

• except pines

• crown points towards light

• highest breakage rate due to snow

Chapter 6 Slowly Does It

trees grow slooooooooooow

• beech

• count nodes on branches of young trees (31)

• as the branch gets longer the nodes stay behind

does this method of age determination work with other species as well?

mother trees want slow growth in their children (32)

• slow growth from light deprivation

• slow growth in young trees key to old age

slow growth in natural conditions (33)

• pencil thick trees are 80 – 120 years old

• woody cells are tiny and contain almost no air

• flexible

• resistant to breakage

• resistant to fungi

mothers deliver sugar and nutrients through root systems (34)

if tree is wider than it is tall, it is in waiting mode (34)

• waiting mode

• look like flat-topped bonsai trees (34)

• leaves (or needles) sensitive to low light

• adapted to shade

When the mother tree dies sets off a chain reaction

• falls to ground

• snaps seedlings

• only trees below that grow straight and tall make it

• meandering trees get caught in darkness again

• this darkness even darker

• more photosynthesis

• fruit becomes sweeter (35)

• attracts predatory herbivores

• honeysuckle

• winds its way around saplings

• if canopy closes honeysuckle dies off before killing trees

• neighbors of mother tree close the canopy gap (36)

• once young trees have made it to the middle story

• no longer threatened by competitors
