Condition of SSSI units   
Lea Marshes SSSI
Only Horseshoe thicket gets a favourable report from Natural England in its latest report , dated January 1, 2014 (though to be fair it looks like there has been no assessment since 2009 despite the fact that it says the data was compiled in 2014).

Condition assessment commentLarge patches of dense bramble and abundant thistles, willow herbs and nettles. Patches of swamp and mire are still present at the northern end of the unit. These are assessed as unfavourable due to dense litter cover, lack of positive indicators for M27 and failure in structural diversity (in relation to invertebrates).

Condition assessment commentThere has been significant progress in the management of some habitats at Walthamstow Marshes, notably through grazing and cutting of grassland areas. The quantity of Michaelmas daisy has been reduced and the rare Apium repens continues to do well. However, the swamp and mire communities for which the site was notified have failed the condition assessment attributes meaning the (assessment?) is unfavourable due to: - dense litter/thatch cover - lack of positive indicator species - undesirable non-woody species (in reed bed and swamp)
