Long-unburnt habitat is critical for the conservation of threatened vertebrates across Australia

Landscape Ecology, Год журнала: 2022, Номер 37(6), С. 1469 - 1482

Abstract Context Increases in fire frequency, intensity and extent are occurring globally. Relative to historical, Indigenous managed conditions, contemporary landscapes often characterised by younger age classes of vegetation a much smaller representation long-unburnt habitat. Objectives We argue that, conserve many threatened vertebrate species Australia, landscape management should emphasise the protection existing patches from fire, as well facilitate recruitment additional habitat, while maintaining historically relevant distributions more recently burned patches. Methods use range case studies ecosystem types illustrate three lines evidence: (1) that depend on mid- late-successional attributes; (2) disturbance habitat tends increase risk future collapse; (3) exhibit characteristics differ historical conditions require context-specific management. Conclusions It is crucial we adequately consider implications altered for activities aim vertebrates. Contemporary lack critical structural compositional components typical required persistence need shift towards strategic, objective-driven approaches identify protect habitats promote their enable recovery declining species.

What did it used to look like? A case study from tall, wet mainland Mountain Ash forests prior to British invasion

Austral Ecology, Год журнала: 2024, Номер 49(4)

Abstract There has been extensive commentary about historical First Nations' land management in Australia, including tall, wet forests, and therefore their condition at the time of British invasion 1788. Popular texts have interpreted records kept by early invaders to argue that areas forest were open through frequent burning Peoples. However, these interpretations conflict with ecological evidence, which is rarely acknowledged public discourse. Here, we present evidence what Victorian Mountain Ash ( Eucalyptus regnans ) forests like invasion. We show invasion, most mainland likely naturally dense wet, with: (1) overstorey trees spaced relatively widely; (2) an understorey consisting a cool temperate rainforest mesic layer. Ecological physiological suggests evolved under conditions where high‐severity wildfire was comparatively rare, leading patterns landscape‐level cover dominated mature forests. This broadly consistent reports from Peoples, accounts, paintings, photographs. These not or park‐like, as may case some other Australian vegetation types. wilderness , but places significance Understanding structure critically important establishing reference for guiding appropriate restoration programmes, especially reinstatement traditional knowledge, after long periods post‐British disturbance degradation.

Abstract Monitoring is critical to gauge the effect of environmental management interventions as well measure effects human disturbances such climate change. Recognition need for monitoring means that, at irregular intervals, recommendations are made new government-instigated programs or revamp existing ones. Using insights from past well-intentioned (but sadly also often failed) attempts establish and maintain in Australia, we outline eight things that should never be done (if they aim useful). These following: (1) Never commence a initiative without committing program. (2) start program clear questions. (3) implement first doing proper experimental design. (4) ignore importance matching purpose objectives design (5) change way you monitor something ensuring methods can calibrated with old (6) try everything. (7) collect data planning curate report on it. (8) If possible, avoid starting necessary resources secured. To balance our “nevers”, provide checklist actions will increase chances actually effectiveness management. Scientists resource practitioners part stronger narrative for, key participants in, well-designed, implemented, maintained government-led programs. We argue mandated threatened species conservation all initiatives.

Ten years of camera trapping for a cryptic and threatened arboreal mammal – a review of applications and limitations

Wildlife Research, Год журнала: 2024, Номер 51(2)

Опубликована: Фев. 8, 2024

For many cryptic mammal species, limited distributional data restrict the scope or effectiveness of conservation actions, particularly in relation to habitat protection and/or management. The critically endangered Leadbeater’s possum illustrates this, with wet forests throughout its range impacted by logging and bushfire. possum’s has been subject major disturbance degradation over recent decades; however, behaviour species meant population trajectories have difficult monitor. Since 2012, surveys for greatly expanded, predominantly based around camera trapping. This paper examines outcomes following a decade targeted trapping this high-profile threatened species. There 1143 detections since representing 57% all period. comparison, there were just 274 comparable period during preceding using other survey techniques. substantial increase records reflects greater effort, but also baited traps at detecting mammal. As consequence, we improved understanding species’ distribution within core bushfire 2009. These detection informed some aspects forest management, including establishment small exclusion areas. Other applications included directing them dens, providing non-invasive means monitoring translocated individuals reproductive success. Several important caveats regarding are discussed, that detection/non-detection may be insensitive declines communally-denning such as possum, where abundance change more readily than occupancy.

Hostile environments, terminal habitat, and tomb trees: the impact of systemic failures to survey for mature-forest dependent species in the State forests of New South Wales

Pacific Conservation Biology, Год журнала: 2025, Номер 31(1)

Опубликована: Янв. 9, 2025

Context The Coastal Integrated Forestry Approval (CIFOA) areas of New South Wales (NSW), Australia include most populations at least two threatened species glider Petaurus australis (Yellow-bellied Glider [south-eastern]) and Petauroides volans (Greater [Southern Central]). NSW Environmental Protection Authority (EPA) administers protocols to conserve gliders within forest compartments intensively managed for timber production by Forests Corporation (FCNSW). These pre-logging surveys retention hollow-bearing trees (HBTs), den trees, associated buffers. Citizen scientists have ground-truthed these in some compartments. Aims We assessed the effectiveness FCNSW outcomes context planned logging operations. Methods used publicly available EPA Native map viewer data this analysis. Key results Although been detected abundant HBTs retained 10 State forests, no were identified any ‘active’ compartment (as December 2023). Thus, isolated or tomb without Several phases not improved conservation logged compartments, even when complied with FCNSW. Conclusions Based on citizen science, implemented under CIFOA result poor other mature dependent species. Wholesale changes process are likely required effective conservation. Implications approaches monitoring research commitment, administration, oversight halt increasingly rapid decline gliders, as well local communities forests NSW.
