This paper reviews the legislation relating to ownership of feral camels in Australia. We find that, as a general proposition, a feral camel is owned by neither the landowner nor the Government (the Crown), unless State or Territory legislation provides otherwise. This occurs in two limited situations and only for New South Wales and South Australia. Relevant State and Territory legislation can prescribe that feral camels cannot be taken or used without a relevant licence or permit, but only Western Australia and Queensland appear to do this.

Changes in total soil carbon (C), nitrogen (N) and natural-abundance N isotopes (δ15N) were measured along three forest-to-pasture chronosequences on pumice soils in the Central North Island of New Zealand. On each of the three chronosequences, exotic pine forests had been converted to intensive dairy pastures 2–11 years before sampling and samples were also taken from remaining pine forests and long-term pastures (40–80 years old).

Encroachment or densification by woody plants affects natural ecosystems around the world. Many studies have reported encroachment in temperate Australia, particularly in coastal ecosystems and grassy woodlands. However, the degree to which published studies reflect broad-scale changes is unknown because most studies intentionally sampled areas with conspicuous densification.

Most of the plantation impact studies reported in literature normally use either one of the sensitivity-based approach or a hydrological model with few actually comparing the impact results from these different approaches. This paper investigates the impacts of increase or decrease in plantations and climate variability on streamflow using two approaches: the sensitivity-based approach (including a non-parametric model and six Budyko framework based models) and the hydrological modelling approach (using Xinanjiang and SIMHYD models) for three medium sized catchments in Australia.

Under the New Zealand Emission Trading System (NZETS), post-1989forestry land (the exotic or indigenous forest land that was not used forplantation on 31 December 1989) in New Zealand is eligible for reward foreach tonne of CO2-eqv sequestrated by reverting from pasture to indigenousscrub. We use the Land Use in Rural New Zealand (LURNZ) model to conduct2 simulations assuming that one tonne of CO2-eqv costs $25; The referencecase is that no one has entered the NZETS, the other scenario is thatthe whole agriculture sector and indigenous forest (but not plantation) haveentered the ETS.

Adaptation in agro-ecological systems will be important for moderating the impacts of climate change. Vulnerability assessments provide the basis for developing strategies to reduce social vulnerability and plan for climate adaptation. Primary industries have been identified as the most vulnerable industry sector globally. We review how primary producers might be socially vulnerable to climate change and develop a ‘vulnerability typology’ of cattle producers based on survey responses from 240 producers across northern Australia.

Monitoring changes in the terrestrial carbon cycle and vegetation health can only be undertaken over large areas and on a regular basis using ecological indicators derived from satellite-based sensors. Climate conditions in Mediterranean ecosystems have undergone, and are projected to undergo, significant change in the future with marked impacts on forest and shrubland vegetation. In the southwest of Australia (SWAU), endemic tree species have experienced significant declines in health and mortality since the early 1990s primarily due to these climatic changes.

In New Zealand and Australia, rural landowners believe that local predator control to protect indigenous biota exacerbates European rabbit Oryctolagus cuniculus problems on their land. We assess the validity of their concerns by reviewing the published literature on effects of predators on rabbit abundance. In New Zealand, where rabbits and their predators are introduced, predators appear to have relatively little effect on rabbit numbers compared with other factors leading to mortality, such as disease, flooding of burrows and burrow collapse.

It is suggested that valuing objects is a distinctive human trait. It is a prerequisite for rational behaviour. Factors that are likely to influence valuations, the difficulties of getting agreements about valuations and the limited perspective of economics as a basis for valuation are discussed generally. Attributes of Otago Peninsula that seem to be valuable and worth conserving are listed and discuss taking into account possible conflicts in getting maximum value from these attributes.

The environmental consequences of agriculture are of growing concern. One example of these consequences is the effect of agricultural pollutants on the Great Barrier Reef (GBR), a world heritage-listed ecosystem lying off the tropical north-eastern coast of Australia. Pollutants from agricultural lands (fine sediments and attached nitrogen (N) mainly from grazing lands, and dissolved N and pesticides mainly from cropping) in catchments draining into the GBR lagoon threaten the health and resilience of this ecosystem.
