Collected Evidence: Collected Evidence: Manage short-rotation coppice to benefit wildlife (includes 8 m rides) We have captured no evidence for the effects of managing short-rotation coppice to benefit wildlife (including 8 m rides) on farmland wildlife. 'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.  Collected Evidencehttps%3A%2F%2Fconservationevidencejournal.com%2Factions%2F90https%3A%2F%2Fconservationevidencejournal.com%2Factions%2F90Mon, 24 Oct 2011 21:32:35 +0100Collected Evidence: Collected Evidence: Restore or create traditional orchards We have captured no evidence for the effects of restoring or creating traditional orchards on farmland wildlife.

Traditional orchards in Ecological Compensation Areas appeared to offer little benefit to birds. A replicated, controlled site comparison study in Germany found that plant species richness was higher on mown orchards than grazed or abandoned ones, but numbers of species and brood cells of bees and wasps did not differ.  Collected Evidencehttps%3A%2F%2Fconservationevidencejournal.com%2Factions%2F703https%3A%2F%2Fconservationevidencejournal.com%2Factions%2F703Tue, 29 Jan 2013 13:17:09 +0000
