A biodiversity offset accounting system

Improving the estimation of ecological equivalence within offset exchanges Key messages: Ecologically robust, user-friendly decision support tools improve the transparency of biodiversity offsetting and assist in the decision making process We developed a disaggregated accounting model to balance biodiversity trades within a ‘no-net-loss’ framework The model improves on other models that use aggregated metrics by […]

When to act?

Setting conservation management thresholds Monitoring is routinely used by conservation managers to determine the state of the environmental values they are responsible for. That might be the numbers of a threatened species or the health of an ecosystem in a national park. When changes in condition are observed, decisions should be made about whether or […]

Surveys that take randomness into account 

The survey of plant and animal populations is central to undertaking field ecology. However, detection is never perfect, so the absence of a species cannot be determined with complete certainty. Methods developed to account for imperfect detectability during surveys do not yet account for stochastic (random) variation in detectability over time or space. When each […]

A model solution for good conservation

Conservation managers often have to make decisions in uncertain and complex situations. This uncertainty can be paralysing: “Do I choose option A or option B? Both have so much uncertainty around them that I just can’t decide!” One way of dealing with this uncertainty is by modelling the different choices on offer to see what type of results they might yield. The correct use of the appropriate model not only helps in making robust, transparent and defensible conservation decisions, it often generates insights on the nature of the system being managed.
