N deposition :: Marsh clubmoss

Latin name: 
Lycopodiella inundata

Impact Type: Deposition of pollutant

Key Concerns:

Marsh clubmoss, Lycopodium inundatum, is a prostate perennial species of wet heaths, found often on bare peaty soil, and occasionally on the margins of lochs. It has a very localised distribution, reproduces by sporangia and is thought to be vulnerable to excess atmospheric Nitrogen deposition via both indirect and direct effects (Biodiversity Steering Group 1995).

Additional Comments:

There is no published research on the effects of air pollution on this species, but negative impacts are most likely to arise from competition leading to loss of light and the ability to assimilate N.
