The privatisation of biodiversity? : new approaches to conservation law
Current regulatory approaches have not prevented the loss of biodiversity across the world. This book explores the scope to strengthen conservation by using different legal mechanisms such as biodiversity offsetting, payment for ecosystem services and conservation covenants, as well as tradable development rights and taxation. The authors discuss how such mechanisms introduce elemhents of a market approach as well as private sector initiative and resources. They show how examples already in operation serve to highlight the design challenges, legal, technical and ethical, that must be overcome.

Predicting and mapping the risk of introduction of marine non-indigenous species into Great Britain and Ireland
Non-indigenous species (NIS) can have adverse environmental, economic and social impacts. Their management is now incorporated into key legislation, including the European Union (EU) Marine Strategy Framework Directive and the EU Regulation on the prevention and management of the introduction and spread of invasive alien species. Prevention of NIS introductions and the early detection of NIS following their introduction are recognised as the most effective approaches for reducing the potential impacts of NIS. This is true for most aquatic environments but especially so for the marine environment, where control and/or eradication are often not achievable. By assessing introduction vector activity, it is possible to identify coastal areas and specific locations where marine NIS may be more likely to be introduced. This study uses data relating to the activity of key introduction vectors; shipping, recreational boating and live animal aquaculture import, to estimate the relative risk of introduction of NIS around coastal regions of Great Britain and Ireland. Spatial analysis was used to create “heat” maps indicating coastal areas of increased relative risk of introduction of NIS by these vectors. The results of the present study will be crucial for the implementation of targeted vector management plans, supporting preventive strategies, and will facilitate a risk analyses of NIS threats to inform monitoring and surveillance programmes.

Patchy distribution and low effective population size raise concern for an at-risk top predator
Aim: Understanding carnivore distribution is important for management decisions that aim to restore naturally regulated ecosystems and preserve biodiversity. Eastern Wolves, a species at risk in Canada, are centralized in Algonquin Provincial Park and their ability to disperse and establish themselves elsewhere is limited by human-caused mortality associated with hunting, trapping and vehicle collisions. Here, we refine our understanding of Eastern Wolf distribution and provide the first estimates of their effective population size. Location: Southern Ontario and Gatineau Quebec. Methods: We used non-invasive samples, as well as blood samples archived from other research projects, collected between 2010 and 2014 to generate autosomal microsatellite genotypes at 12 loci for 98 Cams individuals. We utilized Bayesian and multivariate clustering analyses to identify Eastern Wolves in regions that were previously unsampled. Both linkage disequilibrium and temporal approaches were used to estimate effective population size of Eastern Wolves. Results: Assignment tests identified 34 individuals as Eastern Wolves, primarily in or near two provincial parks: Killarney and Queen Elizabeth II Wildlands. Eastern Coyotes were identified in Bon Echo Provincial Park, Frontenac Provincial Park and Gatineau Park, whereas many of the samples were admixed among the different Cants types. Effective population size (Ne) estimates ranged from 24.3 to 122.1 with a harmonic mean of 45.6. Main conclusions: The identification of Eastern Wolves in the regions of Killarney and Queen Elizabeth II Wildlands Provincial Parks extends the range of Eastern Wolves north of the French River and southward into previously unidentified regions. The effective population size is low and raises concerns for long-term persistence of this threatened carnivore; estimates are dangerously close to critical values recommended for short-term persistence. These results provide important information for upcoming Eastern Wolf recovery plans associated with federal and provincial endangered species legislation.

Is invertebrate conservation in Great Britain best achieved by policies that increase species protection?
We discuss proposals to extend the list of protected insect species in Great Britain and question whether existing species protection measures are appropriate for insects whose ecology is substantially unknown. We highlight the practicalities of applying such measures to very poorly known taxa, whose identification depends upon highly experienced specialists and a tiny pool of relevant expertise. We propose a seven-point plan that would strengthen invertebrate conservation in Great Britain. Our proposals could be applied to other countries with a protected sites network and a desire to improve habitat-based insect conservation measures.Implications for insect conservationOur analysis suggests that insect conservation will not be improved by legislation that restricts the potential for adhoc surveillance that currently provides almost all the data used to monitor rare and threatened insects. We highlight the need for Improvements in the understanding of insect micro-habitat requirements amongst conservation managers. Our proposed seven-point plan provides a structured approach to insect conservation that should improve identification of important insect sites, site management and landscape-scale conservation measures.
