New Zealand's Environment Reporting Series: The Ministry for the Environment and Statistics New Zealand
Growing degree days (GDD) is the measure of how much warmth is available for plant and insect growth during a growing season. GDD information helps horticulturists and farmers predict plant growth and stock development. The GDD value changes in response to climate variations, such as El Niño. Long-term changes in GDD are a measure of changing climate conditions. Further information can be found in: Tait, A, Macara, G, & Paul, V.
