NWT Thorpe Marshes

Paths under water - overtopping from high levels in River Yare (26/27 September).

Thorpe Marshes guided walks are restarting in October, with booking to allow 'track & trace', for a maximum group size of six (the 'rule of six' applies). Booking essential, via NWT - telephone 01603 625540.

Thorpe Marshes, 27 April 2020
Paths are cut, and gates open.

Blogs: Corncrake at Thorpe Marshes (June 2020); Thorpe Marshes, a refuge in lockdown (May 2020); Signs of spring at Thorpe Marshes (February 2020); Three swans a-swimming ... on the path (January 2019, slightly updated from version in December 2019.There is a full blog list in the right hand column.

Thorpe St Andrew Marshes – NWT Thorpe Marshes for short – is one of the Norfolk Wildlife Trust’s newest nature reserves, established in 2011. It's in the Norfolk Broads yet on the edge of Norwich in Thorpe St Andrew. It also happens to be my local patch – just down the road from home and the Honeyguide office, writes Chris Durdin.

September: some of the high summer flowers below are carrying on into early autumn, marsh woundwort and angelica flowers especially. There are still dragonflies, damselflies and a few butterflies on sunny days. Mornings can be wet with dew, of course. Some birds are singing again, notably Cetti's warbler, robin and chiffchaff.

Publications about NWT Thorpe Marshes

NEW: updated version (June 2020) of Dragonflies and Damselflies of the Whitlingham Area, which has a lot of records and photos from Thorpe Marshes. Report on spiders and related species (April 2020): Arachnids of the Whitlingham area by James Emerson, also includes records and photos from NWT Thorpe Marshes.

The Thorpe Marshes wildlife report for 2018-19 includes a range of wildlife records, a review of the year and other activities on the nature reserve.

Key bird records for NWT Thorpe Marshes in 2019 are in James Emerson's The Birds of Whitlingham & Thorpe 2019, which includes Thorpe Marshes reserve in the area it covers.

There are also Thorpe Marshes wildlife reports for 2012-2017 and previous Whitlingham/Bird bird reports. For these, scroll down to 'Wildlife reports & guide'.

NWT Thorpe Marshes Volunteer Group

This group meets once a month on a Friday at the pedestrian railway bridge at the end of Whitlingham Lane, Thorpe St Andrew.  Activities vary and are a mixture of practical conservation work (especially in winter) plus surveying and wildlife ID.

Dates for 2020, all Fridays: 27 March, 24 April, 29 May, 26 June. All are 10am-1pm. Contact alanm@norfolkwildlifetrust.org.uk Cancelled until further notice.

Thorpe Marshes are at the end of Whitlingham Lane, Thorpe St Andrew, Norwich, NR7 0QA, OS Grid reference TG 266 083.  Please note that this is the Whitlingham Lane which is North of the river, NOT the one accessed from Trowse. 

Willow Emerald damselflies

Thorpe Marshes is a great place to see this damselfly in season (late July to October) and to discover more. Willow Emerald egg-laying scars are clear if you know where to look throughout the winter. A local discovery at Thorpe Marshes (January 2018) is Willow Emerald egg-laying scars on domestic apple - a first for the UK. More about this and other unusual places for scars here.

25 May: corncrake, evening. 24 May: evening and after dark. Now farther east within reserve. Also water rail calling after dark. 23 May: corncrake only heard after dark.

21 May: corncrake heard morning, evening and night. One local resident heard it at 10:00. Up to 12 birdwatchers this evening: I was pleased to see social distancing carried out.

20 May: corncrake heard yesterday evening was again vocal this morning between (at least) 06:00 and 07:30 [recording here]. A bird originally released at Pensthorpe is quite likely its origin, though seeing colour rings is impractical as the bird was (mostly) out of sight. This news is noted here given that (1) news of the bird is on the grapevine (2) the few birdwatchers [4 max] attending were impeccably behaved (e.g. no playback used) (3) the bird is very vocal and conveniently heard from a main path and it is on the other side of ditch.
Cuckoo mobbed by jackdaw. Hairy dragonflies; first four-spotted chasers and banded demoiselles of the season.
Corncrake [coronacrake?] calling in the evening. Birdwatchers are requested to follow social distancing conventions: there were clear failures this evening.

Wildlife habitats

The three key habitats at Thorpe St Andrew Marshes are the ditches, gravel pit and grazing marshes - see below.

Other habitats, which are all part of the rich mix, include:

  • rough marsh of willowherb and nettles, attracting many sedge warblers
  • sallow (pussy willow) scrub, good for Cetti's warbler
  • the adjacent tidal River Yare
  • adjacent wet woodland
  • areas of reed, including a reed rond on the river, attracting reed warblers.


Many ditches – also called dykes in Norfolk – have abundant water soldier and frogbit, both aquatic plants. These are indicators of good water quality.

In the Broads, the occurrence of the Norfolk hawker dragonfly, which is the symbol of the Broads Authority, is strongly linked to water soldier. The best place to see these is over the ditches close to the cattle corral.

Water rails and water voles use the ditches, though both are difficult to see.

Gravel pit

Gravel extraction – as at Whitlingham Country Park across the river – has led to the creation of a lake, which has filled naturally with river water. Some may call this a ‘broad’: the true broads are man-made, too, though from flooded peat diggings, and typically are much shallower.

gulls over the gravel pit
Gulls over the gravel pit, December 2011

The gravel pit here attracts wintering ducks, especially tufted ducks (picture below), pochards and gadwalls, moving between here and the Country Park. Unusual ducks call in at times, including smew, goldeneye, red-crested pochard and ferruginous duck over the 2011/12 winter.

Gravel beaches attract ‘loafing’ ducks and wading birds, which include little ringed plovers in spring/summer. Stock doves often feed on plant seeds on the gravel.

Grazed marshes

Livestock are essential to manage the open grazed marshes habitat.

cattle at Thorpe Marshes

Without them, thick grasses and sedges would dominate even more, and would in time be taken over by scrub.

More heavily grazed and trampled areas have a distinct structure of lumps and hollows that attract feeding snipe, and have flowers such as marsh marigold and lady’s smock.

the flood

The flood: the grazing marshes include a 'flood', periodically under water, then drying out, here with a greylag goose and mallards in March 2012. The bright green shoots are emerging yellow flag iris plants.

Monthly walks led by Chris Durdin

Thorpe Marshes guided walks are expected to restart in October, with booking (to allow 'track & trace') for a maximum group size of six. More details later.
Thursday 15 October 10am
Wednesday 4 November 10am
Friday 18 December 10am

All walks are free of charge and last about 2 hours at a slow pace. They start from the pedestrian railway bridge at the end of Whitlingham Lane.

Simply turn up and enjoy. Remember to bring binoculars and a camera if you have them. If you'd like to borrow binoculars, please contact Chris: I usually bring one spare pair but more than that is heavy to carry if they aren't needed!

Boots are recommended as paths can be wet in places. Wellies shouldn't be needed for wading, though can be useful when grass is wet or paths are muddy in winter.

Talks: we can offer a talk about NWT Thorpe St Andrew Marshes. Please contact Chris.

Recording wildlife at Thorpe Marshes through NBIS

As part of the Heritage Lottery Funded Water, Mills & Marshes project, Norfolk Wildlife Trust is encouraging wildlife recording on the nature reserves at Upton Broad and Marshes and Thorpe Marshes.

This is through the Norfolk Biodiversity Information Service through an online process (click on red writing to see the 'wild walks' information).

We particularly welcome records of all/any mammals, amphibians and reptiles. For more experienced naturalists, reference to Thorpe Marshes wildlife reports (see this page) will also reveal where there is potential for new information, for example a wide range of invertebrates.

salix gall

A cluster of leaves on the end of a willow twig, 29 March 2018, is a gall.

The gall is caused by a gall midge called Rabdophaga rosaria which forms camellia galls on the terminal bud growth of various willow species. Each gall consists of 30 or more closely packed leaves which are initially green but as they mature turn brown in late summer but unlike the leaves they stay on the tree throughout the winter with the pinkish midge larva still inside. The larva emerges in spring. The gall is apparently easier to spot than the gall midge.

The willow species will be easier to determine when in leaf.
