Determining the feasibility of training a dog to detect Hieracium species.

  title={Determining the feasibility of training a dog to detect Hieracium species.},
  author={L. Hanigan and Neil Smith},
Hieracium species, commonly known as hawkweeds, have been high on the radar for Australian land managers for many years now with large-scale eradication programs in place to manage infestations in Victoria, New South Wales and Tasmania. The programs rely on surveillance undertaken by humans, which is resource intensive and can be physically exhausting to the volunteers and contractors involved. In an effort to determine if the Victorian eradication program could improve surveillance confidence… Expand
Search strategies for conservation detection dogs
A brief introduction to search theory is provided, then how ideas from search theory might be used to standardise and optimise the use of conservation detection dogs are discussed. Expand
Identifying Invasive Weed Species in Alpine Vegetation Communities Based on Spectral Profiles
This study examined the use of hyperspectral profiles for identifying three selected weed species in the alpine region of New South Wales, Australia. The targeted weeds included Orange Hawkweed,Expand
Preliminary assessment of the uses of sensors and the spectral properties of weed and native species: In Kosciusko National Park, NSW, Australia
The preliminary results indicate that difference in profiles between the weeds and natives is large, and opens further research into determining if the profile is unique enough to then pick-up with remotely-sensed imagery collected by drones, aircraft, or satellites. Expand

Results indicated that dogs are effective at and can safely locate desert tortoises with reliability on the surface and are capable of detecting Tortoises in burrows under a range of environmental conditions. Expand
Hieracium pilosella invasion in the Tierra del Fuego steppe, Southern Patagonia
The results showed that the invading species is widely distributed across the entire Fuegian steppe, in general with low cover and a particular spatial structure having hot spots related to specific land uses, and management actions focused on reducing the presence of hot spots of invasion by means of quick revegetation of bare soil after a massive disturbance event takes place.

The establishment and spread of invasive plants could be enhanced by plant–soil feedbacks that alter the cycling of biologically important elements. In New Zealand, overgrazing of tussock grasslandsExpand
Canine scent detection—Fact or fiction?
The data show that using an optimized training strategy high sensitivity and specificity can be achieved in a short time in two different testing systems, a testing platform and a scent detection board. Expand
Sexual and vegetative reproduction of Hieracium pilosella L. under competition and disturbance: a grid-based simulation model.
It is concluded that a mixed strategy of clonal growth and reproduction by seeds in H. pilosella is necessary to maintain populations of this species in the presence of high interspecific competition and a shortage of open space. Expand
Invasion patterns across multiple scales by Hieracium species over 25 years in tussock grasslands of New Zealand's South Island
Studying patterns of species invasions over time at multiple spatial scales may help us to elucidate important factors driving those patterns and how they change according to temporal or spatialExpand
The importance of dispersal, disturbance, and competition for exotic plant invasions in Arthur's Pass National Park, New Zealand
An assessment of the change in species distributions in the Mingha Valley, Arthur's Pass National Park, over five years showed that many species had increased in range, suggesting that dispersal had limited the distribution of these species. Expand
Changes in soil microbial biomass, metabolic quotient, and organic matter turnover under Hieracium (H. pilosella L.)
It is concluded that the key to the success of Hieracium in the N-deficient South Island high country of New Zealand lies in its ability to control and sequester N supply through modifying the soil organic matter cycle. Expand
Designing a detection experiment: tricks and trade-offs
Detection experiments are relatively new to weed management and provide an opportunity to assess the capability of weed surveys. Long-held statistical principles such as stratification, randomisationExpand
Sexual and Apomictic Reproduction in Hieracium subgenus Pilosella Are Closely Interrelated Developmental Pathways Article, publication date, and citation information can be found at
The induction of a modified sexual reproduction program in AI cells may enable the manifestation of apomixis in Hieracium, indicating that sexuality and apomixedis are interrelated pathways that share regulatory components. Expand
