PORINGLAND LAKES

The Green Heart of Poringland

HABITAT AND WILDLIFE 

Poringland Lakes is a truly important local open space.

Surrounded by housing development, it provides a vital and varied habitat for animals and flora.

The centre-piece is its three lakes and two conservation ponds which are rich in invertebrates and fish.  Created by the extraction of sand and gravel, the lakes attract a great variety of birdlife and are colonized by wetland plants. Dragonflies and other aquatic insects are common.

Lakes

The lakes have a very rich flora comprising rooted, surface-floating and planktonic plant life supporting an abundant animal population.

White and fringed water-lilies are common.  There are patches of marginal vegetation, largely composed of lesser reedmace and common reed.  These areas are very important for breeding dragon and damselflies. 

The edges of the lake have open areas interspersed with willow scrub. 

The lakes are attractive and are the main focus for visitors. 

Temporary Wetland 

This area is quite extensive and is potentially the most important for wildlife on the whole site. 

It is dominated by water purslane, soft rush, sharp-flowered rush, lesser spearwort and gipsywort.  

A woodland bank borders this area and the footpath causeway is surrounded by willow, birch and gorse scrub.

This is the first area to dry out and usually remains this way throughout the summer.

Grassland 


 

Grassland is scattered throughout the site but the largest and most important piece lies just through the access gate (pictured above).  The gravelly acid grassland is heavily rabbit grazed and has a nice open sward with moss patches of bank haircap moss) and broom moss.  Sheep’s sorrel, bird’s foot, procumbent pearlwort and common storksbill occur here.  Of the grasses, sheeps fescue, red fescue and the interesting squirrel tail fescue predominate. 

This area of open low grassland attracts quite different insects to the lush tall grassland of the site and the grassy paths.  This area is covered by a very gelatinous unusual alga.  It is a good area for ants and solitary bees.  The grassland also provides a home for many insects including moths. 

Woodland 

The site contains some limited areas of woodland.  There are a few oak and sycamore trees together with some hawthorn.  Largely confined to the steep slopes, the woodland provides ideal nesting sites for many birds as it remains undisturbed and is difficult to access. 

Scrub 

The site contains two distinct types of scrub, gorse and birch on the higher ground and willow scrub in the damper areas.  This habitat provides food, nesting sites and song posts for a number of breeding birds. 

Wildlife 

Poringland Lakes is a haven for a wide variety of birds, mammals, reptiles and  insects including kingfishers, roe deer, lizards and dragonflies.  The wonderful array of species include: 

Bats (Common pipistrelle, Noctule (UK’s biggest bat)

The University of East Anglia regularly conducts a bat survey at the lakes.

Birds (All common garden birds plus Blackcap, Grey Heron, Jay, Kingfisher, Little Grebe, Moorhen, Tawny Owl - and even the occasional Buzzard.

We hope to bring you more information about the lake's birdlife in the near future.

Family Fortunes 

A family of ducks has returned to Poringland Lakes. 

Earlier in the year a duck and drake were resident at the lakes but recently disappeared, raising concerns about their safety and whereabouts.

Happily today, the mother duck returned with her brood of eight fully fledged youngsters.  The new residents looked perfectly at home in their new abode, digging for food around the lake edges.
