Landscape effects on nest site selection and nest success of Northern Lapwing Vanellus vanellus in lowland wet grasslands
Capsule: Northern Lapwing Vanellus vanellus avoid nesting close to small woodland patches but nest predation rates do not vary with distance to woodland patches, either because risky areas are avoided or perceived nest predation risk does not reflect actual risk. Aims: To explore the effects of woodland patches in wet grassland landscapes on nest distribution and success of Lapwings. Methods: We quantified the effect of woodland patches on the distribution and outcome of Lapwing nests across four wet grassland sites by mapping nest distribution and monitoring nest outcomes. Results: Lapwing nested significantly further from woods than expected by chance. Neither nest predation rates nor the probability of predation occurring at night (thus primarily mammalian predators) or day (primarily avian predators) varied in relation to distance from woodland patches. Conclusions: High levels of nest and chick predation in wet grassland landscapes limit the capacity for breeding wader populations to be self-sustaining. Consequently, identifying manageable landscape features that influence predation rates is an important focus of conservation research. Lapwing avoid breeding close to woodland but, as nest predation rates do not vary with distance from woodland patches, their removal may increase the area of suitable nesting habitat but is unlikely to substantially influence productivity
State of nature 2019
State of Nature 2019 presents an overview of how the country’s wildlife is faring, looking back over nearly 50 years of monitoring to see how nature has changed in the UK, its Crown Dependencies and Overseas Territories. As well as this long-term view, we focus on what has happened in the last decade, and so whether things are getting better or worse for nature. In addition, we have assessed the pressures that are acting on nature, and the responses being made, collectively, to counter these pressures
State of nature 2016
The first State of Nature report that I helped to launch in 2013 revealed the severe loss of nature that has occurred in the UK since the 1960s.
Three years on, I am pleased to see that the partnership of organisations behind that important report has grown. Thanks to the dedication and expertise of many thousands of volunteers working closely with the professionals, we are now able to document even more about the changing state of nature across our land and in our seas.
The news, however, is mixed. Escalating pressures, such as climate change and modern land management, mean that we continue to lose the precious wildlife that enriches our lives and is essential to the health and well-being of those who live in the UK, and also in its Crown Dependencies and Overseas Territories. Our wonderful nature is in serious trouble and it needs our help as never before.
But the State of Nature 2016 report gives us cause for hope too. The rallying call issued in 2013 has been met with
a myriad of exciting and innovative conservation projects. Landscapes are being restored, special places defended, and struggling species are being saved and brought back.
Such successes demonstrate that if conservationists, governments, businesses and individuals all pull together, we can provide a brighter future for nature and for people
An assessment of the state of nature in the United Kingdom: a review of findings, methods and impact
Clear, accessible, objective metrics of species status are critical to communicate the state of biodiversity and to measure progress towards biodiversity targets. However, the population data underpinning current species status metrics is often highly skewed towards particular taxonomic groups such as birds, butterflies and mammals, primarily due to the restricted availability of high quality population data. A synoptic overview of the state of biodiversity requires sampling from a broader range of taxonomic groups. Incorporating data from a wide range of monitoring and analysis methods and considering more than one measure of species status are possible ways to achieve this.
Here, we utilise measures of species’ population change and extinction risk to develop three species status metrics, a Categorical Change metric, a Species Index and a Red List metric, and populate them with a wide range of data sources from the UK, covering thousands of species from across taxonomy. The species status metrics reiterate the commonly reported decline in freshwater and terrestrial species’ status in the UK in recent decades and give little evidence that this rate of decline has slowed.
The utility of species status metrics is further improved if we can extrapolate beyond the species sampled to infer the status of the community. For the freshwater and terrestrial species status metrics presented here we can do this with some confidence. Nevertheless, despite the range and number of species contributing to the species metrics, significant taxonomic bias remained and we report weighting options that could help control for this.
The three metrics developed were used in the State of Nature 2016 report and indications are they reached a large number of audience members. We suggest options to improve the design and communication of these and similar metrics in the future
