Yes they are garish though per WPREDLINKS they can encourage people to make new articles and help expand Wiki The only problem is that a lot of SSSIs have names that dont match area names in reality so its tricky to find matching articles in many cases A bit of local knowledge helps in that respect to link colloquially named articles to formal names used by the government Up to you if you want to retain or remove them there is no strict policy as to their use only not to intentionally red link trivial things not notable enough to ever need an article    RFF
