Forests and Watersheds Study Guide

These flashcards cover key vocabulary terms and concepts from the forests and watersheds lecture notes, including definitions and explanations of critical environmental processes and management practices.

Watershed

An area of land that contributes water to a particular stream, river, or body of water.

Groundwater Aquifers

Underground layers of water-bearing rock that can store and transmit water.

Riparian Zones

Areas adjacent to rivers and streams that help stabilize banks and provide habitat.

Infiltration

The process through which water enters the soil and becomes groundwater.

Deforestation

The clearing or thinning of forests, which can lead to increased erosion and runoff.

Evapotranspiration

The combined process of evaporation and plant transpiration through which water is released into the atmosphere.

High Grading

A poor forest management practice where the best trees are removed first, leading to decreased forest health.

Silvopasture

An agroforestry system that integrates trees with livestock grazing.

Backfiring

A wildfire suppression tactic where firefighters set a controlled fire to eliminate fuel between the control line and the wildfire.

Ecosystem Engineer

A species that creates, significantly modifies, maintains, or destroys physical habitats, impacting resources for other organisms.

Carbon Sequestration

The process of capturing and storing atmospheric carbon dioxide, often through tree growth.

Channel Incision

The process where river channels become deeper due to increased runoff and erosion, often exacerbated by deforestation.

Riparian Buffers

Vegetated areas along waterways that help filter pollutants and stabilize banks.

Interception

The process wherein vegetation captures precipitation, preventing it from directly reaching the ground and reducing erosion.

Agroforestry

The practice of managing forested areas within agricultural settings to benefit both ecosystems and agriculture.

Fire Dynamics

The study of how fires behave, including aspects such as fuel, heat, and oxygen.

Fuel Reduction

Strategies to manage vegetation to reduce the likelihood and severity of wildfires.

Symbiotic Organisms

Organisms that live in close association with another species, often providing benefits, such as fungi assisting insects in breaking down plant tissues.

Mechanical Thinning

A forest management practice that involves the physical removal of trees to reduce competition and improve growth.

Bark Beetles

Insects that bore into trees, acting as agents of tree mortality while also participating in nutrient cycling as decomposers.
