Their observation was that when eroded areas or partly eroded areas are afforestated (planted by trees) or revegetated (fertilizer only) much organic matter is stored in the volcanic soil\\, at least for some decates. When making carbon balance for those areas no infromation was available on how much organic matter\/carbon was leaving the ecosystem in disolved form (DOM). They therefore wanted to quantify the fluxes between the terrestrial and aquatic parts of the ecosystems they were studying. ~~<br \/>\n~~<br \/>\nThe aquatic ecologists had observed that on a regional scale there seemed to be a strong linkage between vegetation cover of river catchments and the aquatic production\\, length of food webs and population densities of fish (charr\\, trout and salmon). This might indicate that the large-scale historic vegetation change descriped earler\\, also had profound impacts on aquatic ecosystems in Iceland\\, and also that large scale afforestation or revegetation activities could possibly also have large impacts on stream ecology in those areas. An interesting question remained to be answered: &#8220;Can we see simliar differences in stream ecology on a hectar scale (1st order catchments; 20-100 ltr\/sec) as is seen in large rivers on a regional scale?&#8221; and &#8220;Has increased input of OM and DOM in afforestation and revegetation areas impact on stream ecosystems in Iceland?&#8221;<br \/>\n<strong>REFERENCES<\/strong>, <a href=\"http:\/\/www.forstreams.is\">www.forstreams.is<\/a> ~~<br \/>\n~~<br \/>\n\u00c1sa L Arad\u00f3ttir\\, Gu\u00f0mundur Halld\u00f3rsson\\, Krist\u00edn Svavarsd\u00f3ttir &amp; \u00d3lafur Arnalds.
