Objectives:1. o understand how overcrowding makes trees

vulnerable to insects, disease, and wildfres.

2. o understand that enlightened managementusing sustained orestry, prescribed burns,

and thinning provides orest health and

ensures that Caliornia will never run out o trees.

3. o understand the relationship between theunction and parts o a tree and those o humans.

Subjects:1. Critical Reasoning2. Forestry3. Ecology

ocus:1. Establish the concept o competition a

element o all orms o lie by asking the studen

to guess what happens i you plant 1000 carrot seeds in

small planter.

Many of them will be weak and small.

Tey will be overcrowded

Many will die because there isn't enough space, nutrienand water for all 1000 carrots.

2. Establish the concept o the orest as a large gardeGardens that are healthy, beautiul, and productivneed to have plenty o water, ertile soil, protectio

against insects and diseases, and thinning o

overcrowded plants. I they remain overcrowded,

there is too much competition or nutrients, wate

and sunlight. Tey soon become stressed and

vulnerable. Tinnings in the garden can be used a

ood or as ertilizer in a compost pile. Tinnings

the orest are harvested trees used or orest prod

or to produce energy in cogeneration plants.

3. Establish the concept o sustainable orestry byasking the students to fgure out a plan by whic

they can keep picking owers rom their garde

all year.

They can replant new flowers as others are

being harvested.

4. Establish the concept o checks and balances innature by asking the students to come up with wain which the orest is kept rom being overcrowde

and becoming weak and unhealthy.

Insects, diseases, natural and controlled fires

and thinning help keep a natural balance in t

forest.

5. Use the Forest Facts discussion themes toreinorce key orestry concepts beore students

initiate the other activity sheets.
