Remote sensing as a technique to assess reedbed suitability for nesting Greylag Geese Anser anser.

We studied Greylag Goose Anser anser nest distribution in relation to reed stem density in the Tgmmerby Fjord reedbed, Denmark, using rial photography to locate nests . Digitised photographs were used to establish a relationship be tween spectral signature and reed stem density. This technique classified 71% of calibration nest sites correctly regarding reed stem density, and most misclassifications had stem density values near the boundary between density classes . When app lied to all 170 identified nest sites; 84% were located in low-density reedbeds
