Good decisions produce results AND help you learn Key messages: Ecological problems are poorly understood, but often require immediate management action. Adaptive management allows action to be taken immediately, and also helps learning. Though commonly cited, true adaptive management is rarely applied. Changing management because of ongoing monitoring at management sites is not adaptive management. […]
Learning about adaptive management
What? where? and when? If we could answer these three little questions when it comes to allocating our available limited resources to saving species and ecosystems then we would be going a long way towards fixing the biodiversity crisis as it unravels around us.
Improving the future of box-ironbark forests with targeted learning Key messages: Value-of-information analysis reveals the expected benefit of reducing uncertainty to a decision maker. We performed this analysis on management of box-ironbark forests. With three management alternatives (limited harvest/ firewood removal, ecological thinning, and no management), managing the system optimally (for 150 years) with the […]
How we can better integrate decision triggers into management Managing natural environments involves making difficult decisions about when to intervene to prevent undesirable changes. Intervening too early may result in unnecessary management actions, while intervening too late may lead to much greater costs or irreversible outcomes. ‘Decision triggers’ is one approach that can be useful […]
Guidelines need to look beyond species traits for good outcomes Key messages: Fire-management guidelines are often based on the traits of individual species We studied the association between the recent fire regime and the plant community in three common vegetation types of coastal SE Australia Guidelines considering different vegetation types as separate management units may […]
Managing threats to communities of declining species with incomplete information Key messages: By combining models of responses to threats with network analyses of species co-occurrence, we developed an approach to predict how an ecological community restructures under threat management Information from a few species on co-occurrence and expected responses to alternative threat management actions can […]
Management guidelines for many fire-prone ecosystems highlight the importance of maintaining a variable mosaic of fire histories for biodiversity conservation. Managers are encouraged to aim for fire mosaics that include all successional states of vegetation, and also include variation in the underlying ‘invisible mosaic’ of past fire frequencies, severities, and fire-return intervals. But how should […]
Do community forests reduce deforestation? Community forest management has been identified as a win-win option for reducing rates of deforestation while also improving the welfare of rural communities in developing countries. But is it delivering the hoped for benefits? Despite considerable investment around the world in community forestry, there is a lack of systematic evaluation […]
Good decisions produce results AND help you learn KEY MESSAGES: Ecosystems are poorly understood, but often require immediate management action Adaptive management allows action to be taken immediately, and also helps learning Though commonly cited, true adaptive management is rarely applied Changing management because of ongoing monitoring at management sites is not adaptive management Adaptive […]
Good decisions for the environment need an eye on the longer term Key messages: Long-term monitoring provides essential evidence on which to base good environmental decisions Good design is essential for effective long-term monitoring Things change over time; to remain effective, long-term monitoring needs to adapt around these changes Partnerships are crucial for ensuring long-term […]
Understanding how pyrodiversity begets biodiversity Key messages: Pyrodiversity describes the variation in the time between fires, their severity, size and patchiness New work is advancing our knowledge of the connection between pyrodiversity and biodiversity but there is a need to further develop approaches that are better tailored to local conditions All around the world fire […]
Reducing the threat to our endangered migratory shorebirds Key messages: We sought the most cost-effective allocation of patrol effort among sites with a limited budget to help manage disturbances to migratory shorebirds We demonstrate a straightforward objective method for allocating enforcement effort while accounting for diminishing returns on investment over multiple visits to the same […]
Mixed policies can meet multiple expectations Key messages: We analysed the potential outcomes of 10 alternative land-use policy scenarios for a high-priority region for forest protection, restoration and rural development in Central Kalimantan All 10 policy strategies are capable of achieving all stakeholder objectives provided at least 29–37% of the landscape is conserved for biodiversity […]
Southeast Queensland’s waterways provide over $10 billion annually in economic benefits through drinking water supply, fishing, tourism, and recreation. But these goods and services are under threat from intensive agricultural, urban development and climate change.
We recently attempted to bridge the gap between theory and practice for one of the worst invasive species in Australia: the cane toad.
Risk it or play it safe? KEY MESSAGES: There is a bias towards placing MPAs in areas that are least threatened We found that conservation targets in our study area could not be met solely by avoiding high threat areas A threat selection strategy should be part of the management toolbox Cost-effectiveness in spatial conservation […]
Connectivity networks and the control of Crown-Of-Thorns starfish on the GBR KEY MESSAGES: Crown of thorns starfish are a major threat to the GBR Outbreaks spread like an epidemic as starfish larvae drift from reef to reef Studying how reefs are connected by larval dispersal is generating valuable insights on how COTS outbreaks can be […]
Sustainable fisheries management in Chile KEY MESSAGES: Assigning user rights to fishers is expected to lead to more sustainable fishing practices by fishers Fishers may choose not to enforce their user rights if they think that government policing of marine areas and punishment of poachers are ineffective In Chile, the government can support fishers’ engagement […]
Ocean zoning with stakeholders establishes the Tun Mustapha Marine Park Malaysia has just established the Tun Mustapha Marine Park off the northern tip of Sabah province in Borneo (Malaysia). At 1.6 million hectares, it’s the country’s biggest marine protected area, and Marxan and CEED scientists have played an important role in the planning process that […]
Automated model-based algorithms compete against humans in conservation games KEY MESSAGES Computer games allow us to compare human-based decisions against model-based decisions On average the ‘robots’ made better decisions than humans using intuition There is real value in the greater use of quantitative methods in environmental management Given all the real world complexities involved when […]
