Forest Management Intro

Forest management introduction

by Karina Frey

• Forests make up about 30% of the earth's surface​

​2 major types of forest

• ​1. Old growth forests

  • ​AKA primary forests

  • ​36% of all forests

  • ​undisturbed for at least 200 years

  • ​reservoirs of biodiversity

• ​2. Second growth forests

  • ​a result of secondary succession

  • ​about 60% of all forests

​Also, Tree Plantations

• tree farms or commercial forests

• about 4% of all forests

• used mostly for paper​

​

​Tree farms deplete the soil of nutrients

​

​Often GMO trees, much less biodiversity in the area

​Old Growth Forests

​

​- Russia

​- Canada

​- Brazil

​- Indonesia

​- Papua New Guinea

​Tree farms / Secondary forests

​

​- China

​- USA

​- India

​- Sweden

​Value of Forests

​Ecological value:

• ​habitat

• ​biodiversity

• ​prevent erosion

• ​purify water

• ​​store carbon, release oxygen

Economic value​:

• ​timber for lumber and fuel

• raw material for many medicines​

  ​source of food

Multiple Select

What are some economic values of forests?

• timber for lumber

• medicinal plants

• increasing biodiversity

• purifying water

Multiple Select

Ecological values for forests include

• prevent soil erosion

• medicinal plants

• provide lumber

• store carbon and release oxygen

Clearcutting - take down all the trees in an area

Shelterwood logging - removing patches​, leaving patches of trees behind

Selective cutting - take only specific trees leaving the rest behind​

​

​Some text here about the topic of discussion.

​Logging methods

Multiple Select

All the clearcutting facts below are true. Which are benefits or pros of clearcutting?

• Clearcutting generates more consistent and higher rates of return for the logging companies and its investors

• Consumer timber/lumber prices are kept low and predictable when clearcutting is used, since savings are passed on to consumers.

• Clearcutting destroys plant life and animal habitats.

• Clearcutting is aesthetically unappealing.

Multiple Choice

True or false: Removing trees leads to an increase in soil and stream temperatures due to decreased shading by tree canopies and the loss of trees evapotranspiration which cool the air around the tree.

• True

What is special about a product with the FSC mark on it?

• It is more expensive
• It comes from rare trees
• It was produced by a well known company

• the wood came from a sustainable source

​Can the Clean Water Act protect forests?

In many places, there are rivers, streams, and wetlands that fall under the protection of the CWA because they run through or near forests. That means the CWA has the potential to protect forests because of their nearness to the water.

Multiple Choice

The Clean Water Act is a _______________ law in the United States that regulates water pollution.

• Local

• State

• Federal

• Interstellar

Multiple Choice

When there is increased erosion in forests, stream water temp goes (up/down) which results in it holding (more/less) oxygen.

• up

  more

• up
