Common Seals in the Wadden Sea in 1999
The coordinated surveys of common seals in the international Wadden Sea in 1999 revealed the following results. The rounded off total number of seals counted in 1999 amounted to 15 200 (2 150 in DK, 5 850 in SH, 4 800 in Nds and 2 400 in NL), and of those 3110 were pups. Though the percentage of pups per total number is of the same order as the years before, the increase of 5.5% of the total population is lower.
