Hamilton, S.K. (2012). Biogeochemical time lags may delay responses of streams to ecological restoration. Freshwater Biology, 57(1), 43-57.
Summary: The article set out to determine the time lags present in N and P movement through watersheds. Understanding the decade or longer time lags will help restoration implementers and monitors be better prepared for the amount of time the project will need before it is ‘successful’. Research Goals:
Rivers in the USA and UK have excess nutrients flowing through them. So much so, that a 90% reduction would be needed to return to a limited system. Understanding the decade or longer time scales at which these nutrients move through the catchment can aid restoration implementers with a better timeline to measure success by. Restoring systems to pre-loaded conditions will take decades or possibly much longer. Reducing nutrient loads added to systems is a must, but the act along will not rectify the issue immediately and this must be communicated with the public as well as restoration funders. Questions:
