\cite{Harrison_1999}. These factors can instead benefit bordering biological communities, or invasive species, which in turn affect underlying ecosystem functioning \cite{Ries_2004}
For example, previous studies have shown nest predation can differ between forest edges and interiors. Most of the evidence of an edge-nest predation effect come from northern temperate zones, with comparatively few studies taken place in tropical, or southern temperature zones \cite{Vetter_2013}.
Increased edge nest predation is still claimed as a universal rule, despite a 2001 meta-analysis found the hypothesis has been rejected in a majority of experiments, and underlying causes of such an effect are poorly understood \cite{Lahti_2001}. Many causes of increased nest predation at forest edges have been proposed including increased richness and/or abundance of predators at the edge (due to its unique ecological makeup), predators using linear geographic features such as edges as a foraging route, and increased prey density at edges in a so-called 'ecological trap' \cite{Marini_1995,Rodewald_2002}.
Nest predation has been used as a proxy for examining edge's effects on predation at forest edges, due to the ease of running the experiment, and ubiquity of birds in woodland habitats and their role as ecosystem. 
In this study we aim to discover whether the generality of edge effect mediated nest predation applies to U.K. mixed deciduous woodland, and identify the predators responsible for this change in predation rates. Our hypothesis is that predation rates will be greater at the forest edge, and the identities of the predators will differ between the edge and interior.

Habitat fragmentation is the process whereby a large habitat is split into a number of smaller patches with a smaller total area. Fragmentation is known to have large, consistently negative effects on existing biological communities \cite{Fahrig_2003} . As well as creating new smaller habitats, habitat fragmentation leads to an increase in the proportion of the new patches that are edge \cite{Crooks_2017}. Edges of forests have different biotic and abiotic factors driving them which can have profound impacts on biological communities. These different factors can lead to different species dominating these edge communities and affect rates of biological processes \cite{Moreno_2014}
