Collected Evidence: Collected Evidence: Use wildlife refuges to reduce hunting disturbance Three studies from the USA and Europe found that bird densities were higher in refuges where hunting was prohibited, compared to areas with hunting. In addition, two studies found that more birds used hunting-free areas during the open season and on hunting days. No studies investigated the population-level impacts of these refuges.  Collected, 24 Jul 2012 12:34:46 +0100Collected Evidence: Collected Evidence: Weight baits or lines to reduce longline bycatch of seabirds Three replicated and controlled studies found evidence for reduced bycatch in some species when using weighted lines. One study found low bycatch rates, but was uncontrolled. In Hawaii and New Zealand, rates of bait loss and bycatch of albatrosses Phoebastria spp., white-chinned petrels Procellaria aequinoctialis and sooty shearwaters Puffinus griseus were much lower with weighted baits or integrated weight lines than with control lines. In the North Pacific, two trials found that bycatch rates of some species was reduced when using weights, but that shearwaters Puffinus spp. attacked weighted lines more often. A study off New Zealand found that attaching weights to lines had only localised effects on sink-rate.  Collected, 24 Jul 2012 17:07:29 +0100Collected Evidence: Collected Evidence: Water nesting mounds to increase incubation success in malleefowlA small controlled in Australia found that two malleefowl Leipoa ocellata nests were abandoned after they dried out, despite being watered, although unwatered nests were abandoned much earlier.  Collected, 29 Aug 2012 16:48:28 +0100Collected Evidence: Collected Evidence: Wash contaminated semen and use it for artificial inseminationA single replicated controlled study in Spain found that semen contaminated with urine could be successfully washed to increase its pH and produced three raptor nestlings.  Collected, 13 Oct 2012 16:47:48 +0100
