Study Notes

Trapping Methods and Risks

Trapping can lead to injuries, fights, and even deaths, especially when multiple individuals are caught together
Non-target species may be caught, which can be protected by law, and may experience capture stress
Some species have escape responses that make them vulnerable to capture, even by an approaching human
Traps can be associated with mortality risks, including drowning, hypothermia, and sunstroke

Capture Myopathy

Physiological changes associated with stressful events can occur in animals, especially in ungulates and carnivores
Muscle damage can lead to myoglobin release into the bloodstream and lactate lowering blood pH
Kidney damage can occur, and capture myopathy can be fatal while the animal is confined or even after release
Release of the animal as soon as signs of capture myopathy appear is the only way to prevent it

Bird Ringing

Bird ringing is a common practice, but not a regulated procedure, and is licensed by the British Trust for Ornithology
Approximately 2,600 certified bird ringers operate in Britain and Ireland
Recovery rates are low, with only 50 returns for every 1,000 birds ringed
Birds are typically in the net for less than 30 minutes, which is generally considered safe
Ringing is associated with some degree of mortality, with 1,646 mortality events out of 1.56 million captures in the UK

Legislation and Regulations

The Game Act 1831, Conservation of Seals Act 1970, Wildlife and Countryside Act 1981, Deer Act 1991, Protection of Badgers Act 1992, and Wild Mammals Protection Act 1996 are all relevant laws protecting wildlife
Schedule 5 lists protected species, including dormouse, otter, pine marten, red squirrel, and water vole
Schedule 6 limits methods for catching certain species, including badger, bats, hedgehogs, otter, pine marten, polecat, red squirrel, and shrews
General licenses or specific licenses for named individuals can be obtained to carry out activities that would otherwise be illegal

Trap Design and Placement

Trap design and placement can exacerbate risks of injury associated with trying to break out
Cage/box traps, snares, nets, pitfall traps, and darting are all associated with risks, including trap design, target species physiology, and non-target species
Traps can be linked to mobile phone networks, which can contact the operator when the trap is set off
Legal obligations require traps to be checked at least once every 24 hours, sometimes more frequently
