Glossary A

AbatementTo reduce the degree or intensity of greenhouse-gas emissions.
AbioticIs a biological term that means nonliving or not alive. It is normally used when referring to the nonliving organisms in nature. These organisms are: temperature, sunlight, wind patterns, precipitation, light and atmospheric gases. Abiotic organisms usually contribute to various factors that affect the living organisms.
Accountable decision-makingThe acknowledgement and assumption of responsibility for decisions and the provision of sufficient transparency to allow stakeholders to measure actions taken against an organisation’s policies and plans. In the public sector these actions must be able to stand the test of parliamentary scrutiny, and public judgements on propriety, ‘value for money’, public interest issues and professional codes of conduct.
AccountabilityThe obligation of an individual or organization to account for its activities, accept responsibility for them, and to disclose the results in a transparent manner. It also includes the responsibility for money or other entrusted property.
Active SpaceThe space within which the concentration of a pheromone or other behaviourally active substance is concentrated enough to generate the required response, remembering that like light and sound pheromones become more dilute the further they radiate out from their source.
Actual net greenhouse gas removals by sinksThe sum of the verifiable changes in carbon stocks in the carbon pools within the project boundary of an afforestation or reforestation project, minus the increase in GHG emissions as a result of the implementation of the project activity.
AdaptationMeasures reducing vulnerability to climate change by increasing readiness for pests and winds; creating woodland networks, and using woodland in flood management, and the adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities.
Adaptation assessmentThe practice of identifying options to adapt to climate change and evaluating them in terms of criteria such as availability, benefits, costs, effectiveness, efficiency and feasibility.
Adaptive capacityThe ability of a system to adjust to climate change (including climate variability and extremes) to moderate potential damages, to take advantage of opportunities, or to cope with the consequences.
Added valueAdded value is equivalent to the increase in value that a business creates by undertaking the production process.
AdditionalityA project funding principle that ensures that a project produces benefits that would not otherwise have occurred. It ensures that European funding does not replace national funding and is only used for non core work being that core work is work that we are committed to undertake.
Adjacent AreaThe Areas directly adjacent to the designated programme coverage area can be Project partners and Lead Partners. There are currently no restrictions or different rules for partners from adjacent areas but all projects must benefit the main programme area.
AESAmateur Entomologists' Society - one of the UK's leading organisations for people interested in insects.
AFBIAgri-Food + Biosciences Institute, Belfast, Northern Ireland
AfforestationPlanting of new forests on land that historically has not contained forests.
AGWEAssembly Government Woodland Estate: woodlands managed by Natural Resources Wales which are owned by the Welsh Government. This amounts to 38% of the woodlands in Wales.
AlateWinged; having wings.
AllopatricTwo or more forms of a species having essentially separate distributions.
AllotypeIn Entomological Terms – Paratype of the opposite sex to the holotype; term not regulated by Code of Zoological Nomenclature.
AMMember of the Welsh Assembly.
Ancient woodlandSites that have been continuously wooded since before 1600AD.
An TaisceThe National Trust for Ireland.
ApicalAt or concerning the tip of any organ, such as a wing.
AppraisalThe process of defining objectives, examining options, and weighing up the costs, benefits, risks and uncertainties before a decision is made.
Aqueous suspensionFor pine weevil suppression, nematode infective juveniles are applied around each stump on a clear-fell site after being dissolved in water.
ArborealLiving in, on, or among trees.
Archaeological TrustsThe four Archaeological Trusts in Wales maintain regional Historic Environment Records, and are concerned with policies relevant to the preservation, recording, interpretation and presentation of the archaeology, historic landscapes and built heritage of Wales.
AR5The Fifth Assessment Report of the IPCC.
ArborealLiving in, on or among trees.
ArthropodInvertebrates with jointed limbs.
Arthropod vectorInsect / ticks that transmit diseases.
ASNWAncient semi-natural woodland: is ancient woodland where the trees and shrubs are semi-natural. These are generally the most important woodlands for biodiversity.
AspiratorA device used to pick up small invertebrates without harming them.
Auct., auctorumIn Entomological Terms – of authors.
AuthorIn Entomological Terms – the person(s) to whom a work, a scientific name, or a nomenclatural act is attributed.
AutochthonousOriginating where found, indigenous.
