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).

	London	Greater London	Waltham Forest	Broadleaved, mixed and yew woodland - lowland	Emily Dresner	3	1005182	2.84	08 Jul 2009	Favourable
Condition assessment comment	The unit has maintained its habitat extent. The woodland is dominated by Salix species with elder and hawthorn. Dominant ground flora species are Heracleum sphondylium, Urtica dioica and Symphytum officinale. Varied structure and good regeneration from coppice areas.

	London	Greater London	Waltham Forest	Fen, marsh and swamp - lowland	Emily Dresner	4	1005183	3.44	08 Jul 2009	Unfavourable declining
Condition assessment comment	Large 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 comment	There 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)
