Summary: This study describes the use of a section of a replanted riparian wildlife corridor by Lumholtz's Tree‐kangaroo (Dendrolagus lumholtzi) (referred to here as LTK) on the Atherton Tablelands in north‐east Queensland, Australia. Selection of plants for replanting had been adjusted to the seasonally inundated clay‐rich and acid soils of the site, and, in some cases, with the aim to establish wind breaks which resulted in a plant composition of this section that differs from known LTK habitats. Through semi‐regular daily observations of individual LTKs over eight years, it was found that LTKs were most commonly recorded on Tallowwood (Eucalyptus microcorys), Rose Gum (E. grandis), Caribbean Pine (Pinus caribaea) and Bunya Pine (Araucaria bidwillii) which were planted as wind breaks in the 1950s and 1980s. On a section planted in 1998, it was found that LTKs used certain tree species more frequently than would have been expected from the relative number in which these species had been planted. This may be associated with certain structural features of the used tree species. The presence of these structural habitat features may allow LTKs to establish home ranges within the restored habitat. Home ranges were calculated for four females, and it was found that they did not differ in size from those reported from other LTK habitats. However, home ranges showed extensive overlaps. The study reveals that LTK will colonise replanted habitat and may be adaptable in its spatial requirements in a restored landscape. [ABSTRACT FROM AUTHOR]

Effective conservation of large mammalian species within a human-modified landscape depends on the knowledge of their ability to utilise available suitable habitat within a matrix of unsuitable habitat. We use incidental sightings of Lumholtz's tree-kangaroo (Dendrolagus lumholtzi) in north-eastern Australia that were recorded by community members in a non-standardised way to assess the functional connectivity of the highly fragmented landscape of the Atherton Tablelands for this species. By applying spatial analytical tools to available mapped information on landscape attributes and the reported sightings it was found that the species shows a low matrix resistance. Since most sightings within the matrix were found within 150mof a patch with suitable habitat and the average distance between these patches was 77 m it can be concluded that Lumholtz's tree-kangaroos are able to reach most fragmented suitable habitat given certain limitations of the accuracy of the used maps and sighting locations. Based on distances between suitable habitat patches and their predominant size of up to 2 ha we expect that the species can include several fragments into its home range. More sightings of Lumholtz's tree-kangaroos than expected by chance within the matrix during dry seasons combined with shorter than expected distances into the matrix suggests the existence of seasonal resource-driven movements of this species. Due to the non-standardised nature of the data the derived conclusions need to be tested in rigorous scientific projects before they can be integrated into the development of conservation strategies for Lumholtz's tree-kangaroos on the Atherton Tablelands.

Summary Cane Toads ( Rhinella marina, formerly Bufo marinus) in restoration sites on the Atherton Tableland in NE Australia consumed invertebrates belonging to 11 different taxa with ants being the most abundant prey item. Principal component analyses showed that the composition of invertebrates in Cane Toad diet is largely a reflection of invertebrates found in pitfall and leaf litter samples suggesting that the species is an indiscriminant feeder. However, pitfall samples contained more Collembola and Isopoda than were found in Cane Toad stomachs. The Cane Toad may benefit from restoration management practices by utilizing food resources enhanced by mulching and providing microhabitats (e.g. rock piles, logs) as shelter. While further studies would be needed to test this practitioners working in areas where the Cane Toad is problematic may consider trade-offs between attracting invertebrates and Cane Toads by monitoring provided microhabitat features.

The article discusses a study which examined the factors that affect the habitat selection of Dendrolagus lumholtzi, a rare Lumholtz's tree-kangaroo, using signs of its activity. Methods utilized include a survey of the presence and absence of scratch marks on tree trunks and faeccal pellets within a 65-hectare fragment of rainforest on the Atherton Tablelands, north-eastern Australia and recording of the structural features of the 315 surveyed tree trunks. Results of discriminant function analysis showed that actively used trees have no epiphytes on the main trunk and a smaller diameter at breast height than inactive trees. It notes that the study's results are contradictory to the preference of complex types of rainforests by tree-kangaroos.
