- Raddling
Fitting rams with a harness that contains a paint block. The paint leaves a mark on the rump of each ewe with whom the ram mates. Lack of a mark tells the farmer which ewes should remain longer with the ram. Sometimes thick paint is applied directly to the ram's chest rather than using a harness. This wears off more quickly and must be renewed regularly.
- Residual herbicide
A herbicide that will remain in the soil and continue to destroy weeds long after it is applied.
- Rigwelted
Of sheep - overturned. A heavily pregnant, broad backed ewe may roll over and be unable to right herself. She is rigwelted. There is also a beer called Rigwelter due to the similar effect it is said to have on humans.
- Rise
A sign that sheep are ready for shearing. The previous winter's greasy wool is lifted away from the skin by new wool that is much easier to cut. The Rise is seen as a yellowish line.
- Rough grazing
Grazing on natural, unmanaged grass and other vegetation growing on mountain slopes, moorland etc.
- Ruminant
An animal (they are all herbivores) that 'chew the cud'. Examples are cattle, sheep and deer but NOT horses. They digest more of a plant than 'single stomached' animals by having a 'rumen' (the first of several stomachs) where the plant material they have eaten are fermented by micro-organisms to produce proteins and sugars the animal can digest.
- Rainforests
Dense forest usually found in tropical areas of heavy rainfall and valued for the richness of biodiversity, aesthetics, and fine quality timbers. Rainforest also encompasses the dense warm temperate and cool temperate forests on Australia's east coast and Tasmania which are relics of an era of much higher rainfall.
- Recovery plans
Comprehensive plans for the recovery of a threatened species of ecological community, including details, timing and costs of what action needs to be taken.
- Regrowth forest
Native forest containing a substantial proportion of trees in a younger growth phase, actively growing in height and diameter. Regrowth forests may contain scattered individuals or small occurrences of ecologically mature, or old-growth trees. (NFPS)
- Regeneration
The re-establishment of a forest following a disturbance, such as a bushfire or forest harvesting.
- Regional Forest Agreements
Regional Forest Agreements (RFAs) are an agreement about the long-term management and use of forests in a particular region between the Commonwealth and a State Government. Its purpose is to reduce uncertainty, duplication and fragmentation in government decision-making by producing a durable agreement on the management and use of forests.
- Reserves
Reserves are forests that are set aside from timber production, either by formal [legal] means, as in the case of national parks, or by informal means, such as management decisions in a management plan.
- Riparian
The riparian zone refers to the area directly adjacent to a waterway.
- Royalties
The fees paid to the forest owner for harvested timber.
