Effects of nitrogen deposition on growth and survival of montane Racomitrium lanuginosum heath
Montane heaths dominated by the moss Racomitrium lanuginosum are in decline, for which increased atmospheric nitrogen (N) deposition may be partially responsible. To test this, field plots in northeast Scotland were treated with either low or high (10 or 40 kg N ha −1year −1) doses of nitrogen (as N...

| description | Montane heaths dominated by the moss
Racomitrium lanuginosum are in decline, for which increased atmospheric nitrogen (N) deposition may be partially responsible. To test this, field plots in northeast Scotland were treated with either low or high (10 or 40 kg N ha
−1year
−1) doses of nitrogen (as NO
3
− or NH
4
+) for 2 years. Although
Racomitrium tissue N increased after treatment, with greater response for low than high N application, activity of the enzyme nitrate reductase and
Racomitrium growth were severely inhibited by increasing N addition.
Racomitrium cover declined following N addition and graminoid cover increased, also with greatest effect at high doses. Of all measurements, only nitrate reductase showed a distinction between NO
3
− and NH
4
+ application. The results demonstrate the detrimental effects of even low increases in nitrogen deposition on the moss heath, suggesting that loss of
Racomitrium and its replacement by graminoids is strongly linked to increased levels of anthropogenic N pollution. |
