Unit 1: THE ROLE OF TREES

A. READING & COMPREHENSION

I. Reading text

For hundreds of years people have

planted trees to serve the needs of

future generations for timber and

tree products. In Europe and Asia

forests were planted by rulers,

church leaders and farmers – for

the people. By planting trees they

particularly and symbolically

showed faith and hope for the

future.

Trees are fundamental to life and

the processes that maintain healthy

soil, and clean air and water. There

is evidence which shows that in

regions where the trees are cleared

to less than 30% of their original

surface area, other sustainable life

processes begin to collapse. Rivers

silt up, soils wash away, and air

quality declines. James Lovelock, a

renowned ecologist, claimed these

breakdowns in natural systems will

in turn affect other word bio-areas

continent or cyclones may occur

more frequently. It will be sad if

these things happen before we

change from consumers to

producers.

questions:

1. What do people plant trees for?

Unit 2: THE DEVELOPMENT OF CONSERVATION

A. READING & COMPREHENSION

I. Reading text

In very early pioneer days,

trees were cut down with no

thought of replacing them.

However, the significance of

trees was indicated as early as

the 1620s by the Plymouth

Colony, when an ordinance

was passed prohibiting the

felling of timber on any

colony land without official

consent. A little later in

Pennsylvania, William Penn,

the governor, ordered that, for

every 5 acres of forest land

cleared, 1 acre was to be left

uncut.

After the United States was

established, laws with

penalties were passed by

several states to prevent

thoughtless waste of the

forests. In the early 1800s

Congress authorized the president to protect live oak and red cedar timber in the state of Florida

and to use the Army and Navy for enforcement. During this same period the first step in forestry

was taken by the government by providing for the growing of live oaks in the southern states for

ship timbers. A federal act also provided for preservation of nearly 250.000 acres of forest land in

Florida, Mississippi, and Louisiana. According to another act passed in that decade, any person

cutting down or destroying living red cedar, live oak, or other trees on federal land could be

punished by the government. These laws and regulations, through which the government tried to

control the forest land, helped call attention to the importance of forests and led to the

development of conservation at the state level.

In January 1867, the first state committee on forest protection was appointed in Michigan, and

Wisconsin followed in March of that year. Two years later the State Board of Agriculture of

Maine appointed a committee to develop a state policy for the preservation and production of

trees. Minnesota created a law in 1871 that granted bounties to encourage the planting of forest

7

trees. The first Arbor Day, a day in late April or early May observed by the planting of trees was

celebrated the following year in Nebraska.

The federal government adopted the Timber Culture Act in the early 1870s. It provided that the

government would donate 160 acres of land to any person who planted 40 acres of that trees with

trees not more than 12 feet apart and kept the trees growing and healthy for one decade. This act,

however, was repealed after 10 years because of serious abuses; too many recipients of these

grants were not honoring their commitments by failing to follow the rules and regulations

pertaining to the grants.

In many instances, while employing fire to prepare their land for cultivation, the settlers

disregarded caution relating to neighboring land. Gross carelessness often resulted in destruction

of property well.
