Another One Bites the Dust: A Look at Logging in our National Parks and Forests

hypothesis
Hypothesis

-With each year, new areas of our national parks and forests are being opened up to logging. The destruction of these once untouched forests is taking its toll on biodiversity in the United States. We predict that the biological cost of logging in the United States, and its expansion into our National Parks will take an irreversible toll on the valuable organisms that depend on these habitats for survival.

introduction and background to logging
Introduction and Background to Logging

-The logging process has been used in North America for thousands of years--Native American use--European use-Europeans were coming from a place already depleted of the majority of forests--While Europe had moved on to coal usage for heat in the 17th century, in the United States continued to use wood until 1840

what is logging
What is Logging?

n: the process, work, or business of cutting down trees and transporting the logs to sawmills(dictionary.com)

-Kinds of logging:--Clear-cutting--Selection harvest--Thinning

effects on land from logging
Effects on Land from Logging

-Depletes soil integrity and nutrient level-Logging roads compact soil preventing further growth and separate habitats-Fires are able to spread more quickly-Tapping into a well-balance system

what is biodiversity

What is Biodiversity?

n: diversity of plant and animal species in an environment

(dictionary.com)

the big concern

The Big Concern

Habitats

Logging Roads = Separation of Species

Old Growth Chopped = Destruction of Unique Habitat

Land Degradation = Flooding, Erosion, Landslides

logging and grizzlies
Logging and Grizzlies

-Endangered species

-Require large open spaces to find a mate

--One of the slowest reproducing mammals, produce only 1-2 cubs every three years

-Logging roads cut off bears from each other

--Increases grizzly mortality rate 5 times

-Decreased the size of habitat

--Now confined to 1-2% of the habitat occupied in the 1800s

(NRDA 2006)

old growth to lines of pines
Old Growth to Lines of Pines

-Old Growth forests are replaced with pine plantations

-From 1950 to 1990 pine plantations we from being

almost non-existent to covering nearly 30 million acres

-Animals such as Pine

Marten and

Cerulean Warbler depend

completely on Old Growth

forests to survive(Jordan 2000)

(Glick 1998)

conclusion
Conclusion
  • Logging is taking a huge toll on biodiversity
  • We should not continue to expand logging, rather decrease it
  • “The US government is the only property owner I know of that, in effect, pays private companies to despoil or deplete its own resources.” Rep. Jim Leach

(Glick 1998)
