Chapter 1 Flashcards
was a significant exploration of the Yellowstone
region, led by Nathaniel P. Langford and including notable figures like John Muir. This expedition contributed to the early conservation movement by documenting the area’s natural wonders and advocating for the establishment of national parks to protect its unique landscapes
The Washburn Expedition of 1870
is a conservation philosophy that values untouched natural landscapes and promotes the protection of wilderness areas free from human influence. This concept emphasizes the intrinsic value of nature, advocating for the preservation of wild spaces for their ecological, aesthetic, and spiritual significance.
The wilderness ideal
are areas designated for sustainable use of natural resources, allowing for practices such as selective logging, non-timber forest product harvesting, and subsistence agriculture while maintaining ecological integrity. These reserves aim to balance conservation and the livelihoods of local communities.
Extractive Reserves
is an interdisciplinary field that combines ecology, biology, sociology, and policy to understand and address the challenges of biodiversity loss and ecosystem degradation. This field focuses on the development of evidence-based strategies for conservation, integrating scientific research with practical management approaches
Conservation Science:
is a philosophical perspective that idealizes rural landscapes and harmonious relationships between humans and nature. It emphasizes the beauty of nature and the importance of preserving traditional agricultural practices, fostering a sense of stewardship and connection to the land.
Arcadian Vision
Reaction against industrialization; emphasized emotional and spiritual connections to nature.

First Chief of the U.S. Forest Service. Advocated
for “wise use” of resources for the greatest good of the greatest number (utilitarian perspective).
Gifford Pinchot (1865-1946)
Formulated the land ethic, viewing ecosystems as
communities of living organisms that humans are morally obligated to respect and protect. His book A Sand County Almanac is foundational to modern conservation thinking.
Aldo Leopold (1887-1948)
Author of Silent Spring (1962), which exposed the
dangers of pesticides like DDT. Her work is credited with catalyzing the modern
environmental movement.
Rachel Carson (1907-1964)
Types of Biodiversity
- Variety of species within an ecosystem or across ecosystems
- Genetic variation within species, crucial for adaptation and survival in changing environments.
- Variety of habitats, ecosystems, and ecological processes within the biosphere.
- Species diversity
- Genetic diversity
- Ecosystem diversity
Ecosystem Services
○ Provisioning services: Resources like food, water, timber, and fiber.
○ Regulating services: Climate regulation, flood control, disease control.
○ Cultural services: Aesthetic, spiritual, recreational value.
○ Supporting services: Soil formation, nutrient cycling, pollination
Challenges to Conservation (5)
- Habitat Loss and Fragmentation
- Climate Change
- Invasive Species
- Overexploitation
- Pollution
Ethical Dimensions of Conservation (3)
- Conservation for human benefit (e.g., ecosystem services) based on resource management principles
- ○ All life forms have intrinsic value; humans have a duty to preserve species.
○ Ecosystems themselves have value, and humans should protect entire ecosystems, not just individual species. - The idea that humans are stewards of the Earth, with a moral obligation to protect natural resources for future generations. Related to the concept of intergenerational justice, where current generations are responsible for the environmental inheritance of future generations.
- Anthropocentric Ethics
- Biocentric, Ecocentric
- Stewardship and Responsibility
