What are invasive non-native species? Non-native species (NNS) are plants and animals which have been introduced (accidentally or deliberately) outside of their native range through human activity. Many non-native species contribute positively to our lives, as livestock, crops, timber, garden plants or pets. However, a small proportion (10-15%) of non-native species spread rapidly and cause damage

Frequently asked questions Why is a sea lice framework needed? Populations of wild Atlantic salmon have been in serious decline in recent decades and are now at crisis point. The pattern of decline is repeated across the salmon’s North Atlantic range and is likely caused, at least in part, by the effect of climate change on the survival of salmon during their time at sea. To build resilience of Sc

Marine aquaculture modelling Computer modelling is used as a guide to determining licensed discharge quantities of anti-parasitic chemicals and organic waste arising from marine fish-farm operations. The modelling tools promoted by SEPA provide robust predictions in most cases, requiring relatively little site-specific information. Nevertheless, the quality of the model outputs is dependent upon g

Can I view the maps full screen?No. The maps can only be viewed within the set frame. Why has the background on the maps changed (2019)?Due to changes to the contract associated with the supply of the background mapping to SEPA, we now have a different background on display. This change took place in December 2018. There are no significant changes to what is displayed, and the mapping presented ha

Part IIA of the Environmental Protection Act 1990 (EPA) (‘Part IIA’), which came into force in July 2000, provides the legislative framework for the identification and remediation of contaminated land. The legislation introduced a statutory definition of contaminated land and is aimed at addressing land which has been historically contaminated and which poses unacceptable risks to human health or the wider environment in the context of the current land use.

Further technical guidance This page brings together a number of ancillary guidance documents and previous email bulletin information relating to modelling of marine fish-farms for CAR licence applications. Auxiliary biomass sampling transect In areas where the tidal residual current is weak, the auxiliary transect (site-specific sampling 2) may be aligned along a bearing reciprocal to the primary
