Lab 6 - Conservation Ecology Flashcards
What is an exotic species?
It is a species not native to an ecosystem, often established purposely or inadvertently by human activity. They are aka alien species and may be invasive or become a pest species
What is groundwater?
It is created by rain that soaks into the ground and flows down until it collects above an impervious zone, known as an aquitard and it is stored in an aquifer.
What is an aquifer?
It is the volume of porous rock or unconsolidated deposits that can store groundwater
What is a riparian zone?
It is a zone of transition from an aquatic to terrestrial system. It is generally thought of as adjacent to permanent rivers/streams, but can be located next to a lake, estuary, pothole, bog, meadow, etc.
What is runoff?
It is the amount of precipitation not absorbed into the ground that flows into surface water bodies or into storm sewer systems - it can cause fluctuations in water levels
What is a watershed?
It is all the land and tributaries draining to a single body of water and is often used as regions for water quality management
What is constraint planning?
A landscape has historical/cultural features and (a)biotic features, which provide both constraints and opportunities for development. Long term monitoring and carrying capacity are often ignored
What is a sanitary sewer?
It is a sewer that collects used water from buildings, including sewage and grey water
What is a stormwater management (SWM) pond?
It provides storm water flow control, recharges ground water, and improves water quality by enhancing the removal of pollutants. They maintain a permanent pool of water in addition to temporarily detaining storm water
