I live in a flat in Barnet which means I have neither a garden, nor a home square that isn't almost completely urban. So I've decided to get to know the wildlife of my local park instead and picked OS square TQ2897 in Trent Park.
It's got a couple of ponds, a stream, woodland and infrequently mown grassland. There's also fields covering about a third of the square in the north and west that may provide me with some farmland birds and arable weeds. I'm a bit of an entomology geek so I'm particularly looking forward to seeing what I can find with my sweepnet when the warmer weather starts. To 1000!
