Size isn't everything when it comes to conservation, even the purchase of a small area of land can be crucial.
Take Portmore Lough in Northern Ireland, for example.
The RSPB has been working here to create the country's greatest undisturbed area of grazing marsh for birdlife including lapwing, snipe and redshank.
So it may surprise you that our extension of Portmore Lough in 2016 consisted of just half a hectare (5,000 square metres) of land.
Still, it was an extremely important purchase. This small area, if managed incorrectly, had the potential to seriously impact the Lough's local wildlife.
We now need to secure more areas across the UK for lapwings to flourish.
Between 1995 and 2012, lapwings declined by 42 per cent in the UK (Breeding Bird Survey 2013). The long-term trend is even worse, and shows a decline of 64 per cent from 1970-2012 (The State of the UK's Birds 2014).
Please make a donation today and help us give lapwings the space they urgently need.
Did you know?
The lapwing's distinctive call gives it the alternative name of Peewit, but it also boasts a number of local names too. Green Plover is probably the most familiar, and is used widely across England and Scotland, but others include 'Tieve’s Nacket' (Shetland), 'Toppyup' (Scottish Borders), and 'Lappy' (Yorkshire)
