Hi Steve,

The local hotspot around you is the Lea Valley. Various patches along the
river & navigation will be nature reserves. It's a well known haunt of
Bitterns in the Winter.

Otherwise Middlesex is a bit thin. You can just make out LNRs & SSSIs on
this map <https://flic.kr/p/dUQCw9> I made from OS Open Data designed to
assist biological recording. They are shown as a diagonal or cross-hatch.
There seem to be a couple up near Barnet, and some big ones missing N of
Stanmore in Middlesex, and the Welsh Harp reservoir isn't shown as one.

The usual sources for finding nature reserves and other places of wildlife
interest which I use are;

   - local Wildilife Trust. Usually the organisation with most reserves in
   a given county or group of counties. In your case these are London
   <http://www.wildlondon.org.uk/>, Herts
   <http://www.hertswildlifetrust.org.uk/>& Essex
   <http://www.essexwt.org.uk/>Wildlife Trusts. It's not a bad idea to
   target getting all the WT reserves done.
   - local Council. For Country Parks & LNRs.
   - local Bird Club. Most bird club websites have quite good accounts of
   popular birding locations. Many of these will be nature reserves.
   - local natural history books. Try the local studies section of a public
   library. For instance Herts WT have published very detailed volumes about
   Moths & Plants quite recently. These usually have a good account of
   significant sites which will be more likely than not nature reserves.
   - local field club or natural history society. These don't exist
   everywhere, but where they do you are likely to find people extremely
   familiar with not just nature reserves but lots of detail of local
   topography.
   - other conservation orgs: RSPB, Wildlife Trust, WWT, Buglife, Plant
   Life etc.
   - Natural England (lists of LNRs, SSSIs)
