Known threats: Exploitation of renewable resources is a threat to the site in the form of agriculture and aquaculture (annual and perennial non-timber crops - agro-industry farming). Pollution/contamination at the site also poses a threat in terms of invasive and other problematic species, genes and diseases; agricultural and forestry effluents (type unknown/unrecorded); and increasing salinity from reduced freshwater input. Damaging recreational use is a threat in the form of human intrusions and disturbance (work and other activities). Lastly, the physical alteration of the site from climate change (severe weather) is a threat to the site.2
