Adapting to Coastal Change at Studland Bay

The coast is an everchanging environment, constantly being reshaped by the waves, winds and tides. Climate change is likely to increase the rate of coastal change that we experience at Studland. That is why it is important that we act now to understand how the coastline might change, and how we can best adapt to this change.

Sand is always in motion, moved by the waves and wind. At Studland the predominantly south-westerly winds naturally move sand from the south of the peninsula and deposit it to the north. The supply of sand to the south cannot keep up, which leads to erosion at this end of the bay. At the northern end of the peninsula, Studland’s dunes continue to grow.

Storms also have an impact on Studland’s beaches, causing large amounts of sand to be washed from the beach into the bay. Some sand may wash back into shore over time, but much will not return.

Climate change will put an increasing pressure on our coastline. By 2100, sea-levels could be 80 cm higher than they are today. This, combined with more frequent storms, heavier rain and more prolonged heatwaves will increase the rate of coastal change that we experience.

Much of Studland’s coastline is eroding at a rate of about 60cm per year, but this is just an average. During extreme weather conditions, we can sometimes lose several metres overnight.  We must make decisions about how best to manage both episodic events and long-term gradual changes to our coastline. We call this process ‘building resilience’.

The National Trust's 'Shifting Shores' policy

How we manage coastal change at Studland is driven by two key policies: the local Shoreline Management Plan, which is produced by the local authority and the Environment Agency, and our national ‘Shifting Shores’ policy. Launched in 2005, the aim of ‘Shifting Shores’ was to encourage coastal National Trust properties to develop long-term plans for their coast, by identifying and putting in place ways to adapt to the increasing pressures of climate change.

A key part of this approach is to work with nature wherever possible in order to create a healthier, more natural environment that can be enjoyed by everyone for years to come. We want to be innovative, working with communities and beach users to create ‘joined up’ and sustainable plans for our coastline.

 

Adapting to coastal change at Studland Bay

Our vision for the Studland Peninsula is for it to be a naturally functioning coastline. This means we will work with natural processes wherever possible, rather than against it; to allow sand and sediment to move freely around the bay. This is also in line with the guidance written in the local Shoreline Management Plan. By doing this, the dunes will be far more resilient to the pressures of sea-level rise and more regular storms.

We are often asked why we do not do more to stop the erosion. Little can be done to effectively prevent the loss of sand that would not alter the natural character of the beach. Hard defences seen on other sea fronts tend to be used to protect structures and properties in built up areas where there is more infrastructure. Natural sites cannot be fixed in the same way without losing the features that make them unique. Groynes, like those seen on nearby beaches in Poole and Swanage, would not protect Studland Bay from the most damaging easterly storms as waves approach parallel to the beach and draw sand out into the bay. Gabion baskets hold a cliff face in place, but starve the beach below it of fresh material, which acts to accelerate the rate of erosion.

Allowing nature to take its course does not mean that we simply do nothing. There are areas of Studland where we are actively adapting to coastal change, to find sustainable ways to maintain both a healthy coastline and facilities that enable visitors and the local community to enjoy being on the coast.

Studland is a popular place for school and university students studying geography to come and see an example of an eroding coastline and dynamic dune system. We have a huge range of resources to help support your learning, including information packs, maps, data and more.

Adapting to coastal change at Middle Beach

We're working towards a sustainable future for Middle Beach and its facilities, which are both impacted by coastal change.

Old maps and photographs show that beach and slope erosion have been occurring at Middle Beach for well over 100 years. The defences have added to the problem by starving the beach of new material so that levels have dropped in recent years.

These defences are now reaching the end of their lives. Instead of rebuilding them, we are removing them which will allow the shoreline to adjust to a healthier and more natural state. This will not only benefit the natural environment, but will also create a more beautiful coastline for everyone to enjoy. We have moved the café and toilet facilities from the cliff edge to the car park, away from the threat of erosion.

Middle Beach Project

5 Sept 2025

Update from project manager, Kelly Marshall

Work begins on 8 September on the final phase of our five-year project to remove failing coastal defences from Middle Beach, Studland. This will allow the area to realign into a natural sandy cove and precious wildlife habitat.

This crucial work is a direct response to the effects of coastal erosion, accelerated by climate change, which saw cliffs fall by up to four metres in a single night. We have gradually been moving structures from the beach, including the former café, shop and toilets, as they came under threat of erosion. Our long-term vision is to allow the cove to realign naturally, creating a coastline more resilient to future environmental challenges.

What does the work involve?

The last stage in this long process is removing the boulders and gabions (wire baskets filled with stone) which are no longer effective against the rising tides. They are also collapsing and pose a risk to the public. As well as the gabions, it involves removing the concrete slipway. Taking out these defences won’t pose any threat to dwellings or other permanent buildings.

More beach to enjoy

Holding the cliff in place with a hard structure like gabion baskets means that the shoreline is not naturally aligned with the coast. When waves hit the gabions, they bounce off and cause erosion of the sand in front of the defences. Over time, this has caused the beach to be submerged by the tide most of the time making it inaccessible.

Removing the artificial structures will allow the beach to replenish itself using sandy material from the cliff. Over time, it’s predicted that this will result in the formation of a sandy cove, with more beach for people to enjoy (see artist's impression, right). The effects might look extreme at first, but projections show that the cliff will realign to become a gentler slope.

Enhanced habitat

We believe that removing the sea defences will also enhance the habitat for wildlife. The increased areas of open sand will benefit insects and reptiles, including rare sand lizards and smooth snakes.

In preparation for the works, licenced ecologists moved reptiles from the site to an adjacent area. An exclusion zone was built around the site to prevent the reptiles from returning until works are completed. In addition, rangers built artificial hibernacula (underground chambers) where the reptiles can shelter for the winter.

Work programme

The work is scheduled from 8 September to 30 October, during which time the beach area will be closed for public safety. However, visitors can still access the car park, toilets and popular Sandy Salt Pig café.
