Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Distribute poison bait for predator control using dispensersA controlled study in New Zealand found that survival of South Island robins Petroica australis australis was higher when brodifacoum was dispensed from bait feeders compared to where bait was scattered.Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F157https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F157Tue, 15 May 2012 12:37:19 +0100Collected Evidence: Collected Evidence: Raise awareness amongst the general public through campaigns and public informationA review of programmes in the USA and Canada argues that education was not sufficient to change behaviour, although it was necessary as a catalytic factor for economic incentives and law enforcement.Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F162https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F162Sat, 19 May 2012 19:59:49 +0100Collected Evidence: Collected Evidence: Provide bird feeding materials to families with young childrenA single replicated before-and-after study from the USA found that most children involved in a programme providing families with bird food increased their knowledge of birds, but there was no significant change in environmental attitudes.Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F163https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F163Sat, 19 May 2012 20:07:24 +0100Collected Evidence: Collected Evidence: Angle windows to reduce collisions by birdsA single randomised, replicated and controlled experiment in the USA found fewer birds collided with windows angled away from the vertical.Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F166https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F166Sat, 19 May 2012 20:14:31 +0100Collected Evidence: Collected Evidence: Plant new hedgesA small study from the USA found that the population of northern bobwhites increased following several interventions including the planting of new hedges.Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F178https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F178Wed, 30 May 2012 14:09:27 +0100Collected Evidence: Collected Evidence: Mark nests during harvestA replicated study from the Netherlands found that northern lapwing Vanellus vanellus nests were less likely to be destroyed when they were marked, compared to when they were not.

Effects were greater on clutches that were older when moved.

Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F197https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F197Wed, 27 Jun 2012 17:55:08 +0100Collected Evidence: Collected Evidence: Take field corners out of managementA replicated study in the UK found that overwinter survival of grey partridge Perdix perdix was higher where field corners were taken out of management than on other sites for one of three winters. There was no relationship with the intervention and brood size, the ratio of young to old birds or density changes.

Two other repellents did not reduce consumption as effectively.

There were localised problems with overgrazing, burning and scrub encroachment.

A study from Hawaii found that keeping birds warm in a ‘mock’ translocation in Hawaii increased survival, although all birds suffered some loss of condition.

A second review of the same programme found that removing eggs from clutches as they were laid increased the number laid by females.

Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F624https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F624Sun, 14 Oct 2012 14:38:18 +0100Collected Evidence: Collected Evidence: Release captive-bred individuals into the wild to restore or augment wild populations of owls A study in the USA found that a barn owl Tyto alba population was established following the release of 157 birds in the area over three years. A replicated, controlled study in Canada found that released burrowing owls Athene cunicularia had similar reproductive output, but higher mortality than wild birds, and no released birds returned after migration, although return rates for released birds’ offspring were no different from wild birds.

In Sweden, released white storks Ciconia ciconia from North Africa produced fewer than half the chicks as those that naturally re-colonised, whilst both studies found that storks and little bustards Tetrax tetrax were less likely to migrate than birds originating in the release area.

The Saudi Arabian study found that introducing a model fox (as opposed to a live predator) to cages did not increase post-release survival. Introducing a live fox to the cage increased post-release survival more than other techniques used.
