Migration is physically demanding, and migratory species are highly reliant on places to stop, rest and feed along the way. Unfortunately, human activities are making it riskier for animals to travel, while also reducing the number of places they can travel to.
Priorities for migratory networks
How much do we need to know to develop a good plan? KEY MESSAGES: Spatial priorities for sea turtle conservation are very sensitive to the type of information being used Setting conservation targets for migration tracks altered the location of conservation priorities Telemetry data needs to be better harnessed in conservation planning It’s quite a […]
The multiple challenges of planning for complex migratory networks Migratory species are pretty amazing. Some species travel vast distances in a single migration. An individual bar-tailed godwit, a migratory wading bird, was once tracked as travelling an incredible 11,000 km in a single flight! Arctic terns travel the equivalent of to the Moon and back […]
Geographic range size and extinction risk Geographic range size (the size of a species’ distribution) is often treated as a fixed attribute of a species for the purposes of calculating extinction risk (see the segment below, on EOO & AOO). All else being equal, species occupying smaller geographic ranges are assumed to have a higher risk […]
Conserving migratory animals has always been a challenge because they face a range of threats at different parts of their migration, often separated by vast geographical distances (consider the threat to migratory birds from the loss of tidal flats in Asia, see p8). Addressing threats to population viability of migratory animals therefore requires integrating information of how individuals move, survive and reproduce throughout their annual cycle
