Glossary

Recycling means the treatment and reuse of waste for new products.

A person’s ecological footprint is a measure of the space required to support their lifestyle. This includes food, clothing, mobility and various resources. If one divides the biologically productive usable area of the earth (2010: 11.9 billion ha) among the earth’s population, about 1.7 ha are allotted to each person. The average footprint of Austrians

The term “emission” means the discharge of pollutants and other disruptive factors into the environment. In environmental law, this includes discharges from toxic, harmful or environmentally hazardous chemical substances. Common examples are gaseous or particulate pollutant emissions (from cars and airplanes), liquid emissions (from contaminated sites and factories), particulate emissions (from dumps), road noise, and

Botany is a branch of biology and deals with the science of plants.

In the context of landscape planning, the term “zoning” refers to the administrative act by which something is released for public use and subject to public law.

Red lists provide information about the endangerment status, the endangerment factors and the measures to protect the species in certain regions.

Fossils are the remains of living things or traces of living things that are more than 10,000 years old. The formation of fossils is called “fossilisation”. Fossils are formed when dead living beings are sealed off from oxygen in sediment and no more change processes take place in the earth’s crust.

The water and air-filled cavities in the soil are called “soil pores”. The pore space represents the entirety of all soil pores. Pore spaces and pore size distributions can be very different depending on the grain size distribution, the soil structure, the content of organic matter and the humus form.

The flora – also called “plant world” – includes all plants and their habitat.

The habitat and the organisms living in it are called ecosystems. The plants, animals, microorganisms and the non-living environment all interact.

Under the influence of hydrocarbons and oxygen, nitrogen can be converted into photo-oxidants with the help of solar radiation. These include ozone, peroxyacetyl nitrate (PAN) and nitric acid. All of these contribute to air pollution.

Originally, a “pergola” was a sun protection standing on columns or pillars, which adorned the path from the house to the terrace. Today, these canopies are placed in all possible variants in different places as sun protection. They are usually overgrown with climbing plants.

“Vegetation cover” means the plant layer covering the ground.

Nutrients and energy are passed on in cycles in almost all ecosystems. Producers are the organisms that produce biomass. These are mainly plants and bacteria. Consumers consume this biomass and are dependent energy-wise on the producers. Consumers are mainly humans and animals. Decomposers are the creatures in the producer-consumer-decomposer cycle that are responsible for breaking

Soil conditioners are soil-improving soil additives that can increase soil fertility and soil life. Due to their low nutrient content, soil additives are not considered fertilizers.

Oxidation is a chemical reaction in which a substance emits electrons. Another substance absorbs the electrons and is reduced in the process. Oxidation is thus a partial reaction of a redox reaction (a chemical reaction in which one reactant transfers electrons to the other).

Expanded shale consists of crushed shale. The grains have a plate-like shape and are very light.

This chemical substance is better known by its trivial name, laughing gas. The chemical molecular formula is N2O. Nitrous oxide is a greenhouse gas and contributes to global warming. The gas is mainly used as an anaesthetic.
