  • The History of Rainham Marshes PART 1

    me again

    Over the next few weeks I shall periodically be posting a short little history piece about the reserve. The site is steeped in history, some of it very old so watch out for more updates.

     

    In the beginning

    Rainham’s landscape has not always been dominated by open marshes, and the area has undergone some fascinating transformations over thousands of years. Its geomorphological history started with the build-up of silty glacial deposits overlying the Eocene marine London clays and gravels up to about 13,000 BC. After this, the cold, treeless steppe and tundra habitat was replaced with a covering of birch and pine. However, from 6,000 BC sea levels rose and during the Mesolithic and Neolithic epochs, spanning 8,000-2,000 BC, the site saw two periods of inundation, each followed by dense forestation.

    If you visit the reserve at low tide you can see the remains of the Neolithic forest protruding through the silty mud of the River Thames. The Thames was way to the south when these trees were growing here. Similar stumps can be seen on the other side of the river at Erith and periodically we unearth large pieces of this anearobically (no air) preserved wood from ditches out on the marsh.

    The Rainham area has been occupied by man since the Palaeolithic (35,000-10,000BC), with hand tools found in the nearby Aveley shingle terraces, and there is evidence of Bronze and Iron Age (2,200 BC to 43 AD) habitation and Roman occupation (43-140 AD) nearby.  

     

  • Snails everywhere!!

    A little bit of drizzle and the snails and slugs are out in force! Hundreds along the river wall this morning!

    Just need some song thrushes to drop in and start smashing!

  • Gannet on the list!

    A weird week with 25c on Wednesday and blue sky and sun and howling freezing northerlies and rain on Sunday but we did get no less than three juvenile Gannets onto the Rainham Marshes year list! Today has gone back to mild and calm. You could probably skim a stone across the Thames today!

    Small Coppers are stil on the wing with several mated pairs to be found.

    Skylarks and Meadow Pipits on the move along with 60 House Martins. A single male Ruff was in the bay this morning but there was no sign of yesterdays four Grey plovers.
