Special nature
Ilperveld
Between Landsmeer, Den Ilp, Ilpendam and the North Holland Canal lies the Ilperveld: a watery low-peat landscape with long ditches, reed beds, wet meadows, quaking bogs and hundreds of narrow peat islands. Close to Amsterdam, this quiet world supports black-tailed godwits, lapwings, reed birds, peat mosses and root voles. The landscape developed through peat formation, turf cutting and centuries of water management and survives only through careful water-level control, grazing and ecological restoration.
Why go here?
Just north of Amsterdam, the Ilperveld preserves a finely divided world in which land and water are almost equally important. Walking paths and a bird hide overlook wet meadows, reed margins and meadow birds, but the fragmented nature of the area becomes clearest from a boat. Narrow waterways run between low peat islands and pass quaking bog, marsh and quiet grassland. The area can be visited independently, while paid boat trips and excursions offer a deeper experience.
What do you see?
An open peat-meadow landscape with long ditches, wide skies, reed margins, wet grasslands, peat islands, old embankments and small meadow mills. Black-tailed godwits, lapwings and redshanks stand out in spring. Marsh harriers, bitterns and sedge warblers live in and around the reeds. From the water, the narrow islands, quaking bogs and quiet marsh edges come much closer than they do from the public paths.
What can you see when?
Choose a month to see which animals, plants or fungi are most likely then.
Black-tailed godwit
In spring, look for it on wet meadows and open plots, where its calls, display flight and long bill belong to the peat-meadow scene.
Northern lapwing
Conspicuous by its tumbling flight and call above open grassland, especially in early spring when the plots are still wet and low.
Common redshank
Often heard on damp meadows and along ditch edges, recognisable by its alert call and red legs.
Western marsh harrier
Hunts low over reed beds, wet meadows and open water, with slow wingbeats and long gliding flights.
Eurasian bittern
Rarely visible in the reeds, but in spring its deep booming call can give the marsh a hidden presence.
Sedge warbler
In reed edges and rough banks, it is mostly recognised by song and movement, often heard before it is clearly seen.
Root vole
Almost never visible: the root vole lives in wet, rough peat vegetation and says something about the quality and isolation of this low-peat landscape.
Peat moss
Peat moss belongs to the area’s fragile wet vegetation and reveals where the landscape still breathes like true peatland.
Cross-leaved heath
In suitable peat-moss-rich places, flowering cross-leaved heath can add a subtle purple layer to the wet peat vegetation.
Common reed
Reed shapes the banks, waterways and quiet corners of the area and provides cover for marsh birds.
Dragonflies
On warm days, dragonflies fly above ditches, waterways, reed edges and sheltered corners of water.
Sheep, cattle and goats
Grazers are part of the management of open meadows and edges; they keep parts of the peat landscape low and visible.
Why it matters
The Ilperveld shows how nature, farming and water management are intertwined in the peatlands of North Holland. The area is important for meadow birds, marsh birds, quaking bogs, peat mosses and the root vole. At the same time, it is vulnerable to drying, subsidence, nutrient-rich water and overgrowth. Only sufficiently high water levels, open meadows, quiet reed zones and targeted restoration allow its different habitats to coexist.
The deeper story
The Ilperveld lies directly north of Amsterdam, between Landsmeer, Den Ilp, Ilpendam and the North Holland Canal. On a map it resembles an open polder, but at close range the landscape consists of hundreds of narrow peat islands. Long ditches and waterways divide wet meadows, reed strips and marsh. Land and water are so closely interwoven that the area has a completely different character from a boat than it does from the road.
The ground consists of peat formed over thousands of years from dead marsh plants. From the Middle Ages onwards, the area was drained and used for farming and turf cutting. Digging and extraction created long waterways and narrow plots. Not all peat was removed or dried out. A finely divided landscape remained in which grasslands, reeds, ditches and peat remnants lie close together.
The Ilperveld forms part of a larger low-peat complex with Varkensland, Oostzanerveld and the Twiske. The former influence of brackish water, patterns of old reclamation and the continuing struggle against land subsidence remain visible. The landscape is therefore neither purely natural nor an ordinary agricultural polder. Centuries of use and water management created a half-wet world that now has great ecological value.
In spring, the open grasslands are important for black-tailed godwits, lapwings and redshanks. They breed on low plots and feed in damp soil and along ditch margins. Their success depends on sufficiently high water, late mowing, tranquillity and abundant insects. Wide skies and open views are as important to these birds as wet ground.
Reed beds and marsh edges support different species. Marsh harriers hunt low above reeds and water. Bitterns usually remain hidden, but their deep calls can carry far in spring. Sedge warblers and other small marsh birds move among stems and rough banks. The transition from open meadow to dense reed makes the area suitable for a wide range of birds.
The vegetation below eye level is equally remarkable. Peat mosses grow in some wet places and form quaking bogs: floating or unstable mats that move with the water. Such vegetation develops slowly and is highly sensitive to drying and nutrient-rich water. Cross-leaved heath may add a purple tint to peat-moss-rich areas.
The root vole lives in wet rough vegetation and is almost never seen. It benefits from isolated habitats that remain regularly wet. Its presence shows that the value of the Ilperveld is not determined only by conspicuous birds, but also by hidden species dependent on a stable marsh landscape.
The area does not remain open by itself. Grasslands are mown or grazed by cattle, sheep and goats. Elsewhere, reeds, scrub or nutrient-rich topsoil are removed. Water levels are managed to prevent the peat from drying and oxidising too quickly. Without this work, meadows would become overgrown, quaking bogs would disappear and the peat would continue to subside.
Water management is complex. Levels that are too low accelerate subsidence and drying, while poor water quality can also damage vulnerable peat vegetation. Nutrients from farming, atmospheric deposition and imported water favour fast-growing plants. Restoration therefore requires not only more water, but also cleaner water, suitable grazing and sufficient tranquillity.
A walking path and bird hide are accessible from the visitor centre on the Kanaaldijk. They reveal mainly the edge of the area. Independent visits are free along the public paths, but the scale becomes clearer from a boat. The narrowness of some islands and the depth of the waterways then become apparent. Paid boat trips and excursions are offered at scheduled times.
The proximity of Amsterdam remains noticeable. Buildings and infrastructure may appear on the horizon, but traffic and city quickly disappear behind the reed margins. What remains is water, wind, birds and low green islands. This contrast makes the Ilperveld distinctive: a fragile peat marsh in one of the busiest parts of the Netherlands.
The Ilperveld does not tell a story of untouched wilderness. It is a landscape excavated, drained, grazed and managed by people. Yet that long history produced a valuable mosaic of meadow-bird grassland, reed marsh, quaking bog and open water. The future of that mosaic depends on the same factor that has shaped the area for centuries: the way water is managed.
