A Landscape System Analysis

A.1 Landscape layers and their system context

Geomorphology, landscape units and coastal typology

  • Description of evolution, status quo and driving forces, is the coastal typology changing? Why is that? (approx 200 signs)
  • add 1-2 graphical representations to the image gallery, you can add more if you like


Kakumäe bay is part of Tallinn bay which is on the southern coast of the Gulf of Finland.

According to the coastal typology adopted for the EUROSION project, Kakumäe bay can be described as a combination of Hard rock coastal plains (Hard rock sandstone cliffs and limestone steps), Soft rock coasts (Moraine coastal bluffs) and Wave-dominated sediment, Plains (Silty, sandy, gravel, pebble and boulder beaches). Within these major coastal types several coastal formations and habitats occur, including bare sandy, gravel and pebble-boulder beaches, vegetated shores and windflats. [4]

Recent geological history of this area is largely related to the isostatic uplift of the Earth’s crust in the northern part of the Baltic Sea region, which continues till now( 2mm annually in the Tallinn bay). Due to the uplift of the Earth’s crust, the coast and beaches are of emergent character. [5]

The coast within this area can be split into several morphologically different units, from west to east:

Tiskre: A flat coastal wetland is overgrown by bulrush and reeds. Fine sand and silt deposits cover the bare beach, which descends gradually to a very flat sandy foreshore forming atypical windflat. A wide-scale residential development is taking place in the backshore partly reclaiming the wetland.

Kakumäe promontory: It is separated by Kakumäe bay and Kopli bay. The eroded hard rock sandstone cliffs and limestone steps occur in there. A steep up to 20 m high sandstone cliff overtopped by a thin layer of moraine till, is behind a narrow gravel-boulder beach. Also the foreshore profile is relatively steep. There is sandstone bedrock and erratic boulders with pebble from the bench. [6]

Land use

  • settlements, infrastructure, agriculture, resource extraction, natural areas, energy production...
  • description of evolution, status quo and driving forces, is the land use likely to change? Why is that? (approx 200 signs)
  • add 1-2 graphical representations to the image gallery, you can add more if you like


According to CORINE land cover map, the case study area (within 5 km inland) can be described as a combination of

1) Inland marshes

2) Discontinuous urban fabric

3)Coniferous forest

4) Mixed forest

5)Pastures

6) Land principally occupied by agriculture, with significant areas of natural vegetation

7)Transitional woodland-shrub

8) Industrial or commercial units


The coast area ( within 2 km inland) is predominantly an urban area and coniferous forest.

In Tiskre and Kakumae, an extensive residential development of high standard is currently taking place at the coast in the suburban zone.[7]

Waves erode the sandstone cliff in Kakumae. If the storm wave and surge action increases, the coming decades might witness a more intensive retreat of the shoreline and the cliff edge. Because of erosion impact, the new residential area is located next to the escarpment and might be eventually threatened if erosion increases. [8]


Green/blue infrastructure

  • What are the major potential elements of a green/blue infrastructure network? Are these likely to change/disappear? Why is that?
  • You find my background material on green infrastructure in our reading list
  • add 1-2 graphical representations to the image gallery, you can add more if you like


Major potential elements of the green and blue infrastructure network of the cliff coast area are:

Green: 1) coastal forestpark 2) sand dunes with rose hips and other plants 3) cane grass 4) arable land 5) private gardens (living area consist mainly of private houses with gardens) 6) street trees & hedgerows 7) grasslands, pasturelands 8) Kakumäe bog 9)Landscape protection area of Rannamõisa 10) Landscape protection area of Muraste 11) Muraste bog 12) hiking trails (Tabasalu, Aura, Muraste)

Blue: 1) Kakumäe bay (part of Tallinn Bay) 2) Tiskre stream and its corridor 3) Harku lake


Kakumäe is a suburbanization area situated in Tallinn, Harju County, which is one of the most densely populated counties in Estonia. There are quite many green areas but the distribution of green network in that area is uneven. The uneven stationing is influenced by spatial planning and building actions of a growing city. New living areas are built in the expense of forest and coastal areas. [9]. According to the Environmental impact assessment strategy of Tallinn 2030, the reason lies in the lack of planned greenfields in residential areas not being constructed [10].

Biggest threat to the green network in Kakumäe area is the degradation of forest and coastal areas for building new development. Although the local government of Haabersti city part has taken for its vision to preserve and maintain the existing forest on the peninsula of Kakumäe as an enrichening element of the living environment. [11]. In the thematic plan of The Green Areas of Tallinn this forest and coastal area is established as a conflict area, mainly because of the fear of the disconnection of green infrastructure network.

Other threat to coastal green areas is the weathering of rocks and soil from the cliff coast because of the waves of the sea, wind and other weather conditions. But also the growing number of people, who use the beach area for recreational purposes, needs to be regulated [12].

There are two landscape protection areas on the coastline: Rannamõisa and Muraste. Both of them are made for the protection of the limestone cliff and coastal forest in North-Estonia mainly to save them from development. Both of them are also stated as globally important protection areas and habitat places. [13] [14].




Actors and stakeholders

  • Who is driving changes in this landscape? Who is affected by those changes?
  • Draw a stakeholder and/or power map: Who is affected highly but with low power? Who has high power but is not affected?


Kakumäe bay is a part of Harku municipality and Kakumäe peninsula is in Haabersti district. Harku municipality is a municipality located west of Tallinn, with a northern limit of 22 km in the Gulf of Finland. In Harku municipality the main charges are on the municipality governor. His main tasks are General Management, Municipality Representation, Planning and Building Co-ordination. The Haabersti District is a city authority in Tallinn, the aim of which is to ensure the provision of urban residents and businessmen in Haabersti district, the availability of public services and the development of the district, its hubs and settlements, and the functioning of the infrastructure, taking into account the needs and interests of the inhabitants of the district, as a whole of interest.( Haabersti Linnaosa Valitsuse põhimäärus, chapter 1, § 1)

Kakumäe People's Society is a non-profit organization , whose goal is to improve and revitalize the living environment of the region.

In order to achieve its goals, the agency carries out the following activities:

1. Organizes joint activities of the members of the Society and public events related to the region;

2. Represents the interests of the members of the Society in all the activities concerning the region and actively contributes to the development of the region's living environment;

3. Interacts with local people, city authorities and other relevant parties


Sacred spaces and heritage

  • Which places/elements hold cultural value and to whom?
  • You may add a map and some images, please also explain in your caption why these elements are valuable


On the left side of the shore of the Kakumäe bay, near Muraste protection area, there are naval fortresses of Peter the Great. Built between 1913-1917, they are now considered as cultural heritage objects of Estonia. Peter the Great's naval fortress, also called the Tallinn-Porkkala defence station was a Russian fortification line, which aimed to block access for the Russian capital Saint Petersburg via the sea. The plans for the fortress included heavy coastal artillery pieces along the northern and southern shores of the Gulf of Finland. The emphasis was put on the defences of the gulf's narrowest point, between Porkkala (in Finland) and Tallinn (in Estonia). This was a strategic point, as the two fortresses of Mäkiluoto and Naissaar were only 36 kilometres apart. The coastal artillery had a range of about 25 kilometres and could thus "close" the gap between the shores, trapping enemy ships in a crossfire [15].

Near the left side of the coast, not far from the naval fortress, there are also ancient fields with findings of cultural layer. There are preserved stonebeds and stoneheaps of the ancient fields [16]. As remains of ancient settlement areas, there are also stone graves near the fields.

The shores of Kakumäe bay are considered valuable in sense of nature. Most of the cliff coast is covered by Rannamõisa landscape protection area, which main aims are to protect cliff coast (height up to 32 m), forest on and beneath the cliff, unique natural habitats and rare animal (Eptesicus nilssonii, Pipistrellus nathusii, Nyctalus noctula) and plant species (Orchis mascula, Cotoneaster niger) [17]. There are also Caves of Tilgu and outcrop of sandstone which both are under nature protection [18].

There is also Muraste nature protection area which aims are also to protect the cliff coast of North-Estonia and natural habitats [19].

In addition to the named protected areas there are few objects outside the borders of protected areas – boulder of Black Stone in the top of Kakumäe peninsula, boulder of Tari between Rannamõisa and Ilmandu and smaller areas of plant species protection.


Visual appearance and landscape narrative

  • Which elements are essential for the landscape character?
  • Has the landscape been painted or otherwise depicted, when and whom? Which elements are essential?
  • Which narratives exist? Who has written about this landscape or depicted it in some way?
  • You can add text and images


As Kakumäe bay coastline has various landscape settings starting with usual and flat sandy beach to high (32 m) cliff coast, then it is loved by painters. Painters find inspiration in wavy sea, rocky beach and cliff coast. Small and arched bay allows to enjoy the sight of long land and sea border in the horizon.

Professional and hobby-photographers also use Kakumäe bay as their worksite. Pink sunsets, capital city towers in yonder, ice forced to coast by waves in winter are all taken into photographs. Nowadays, as drone pictures are available quite easily, whole coastline as panorama picture is often presented in wall art.
