The document summarizes a study on people's preferences and acceptance of different development strategies on urban cemeteries in Berlin. It finds that "green development" strategies like urban wilderness areas and community gardens are significantly preferred to "grey development" strategies like buildings. Areas with meadows and wilderness are preferred to mown lawns for managing green spaces. People who visit cemeteries for nature experiences or spiritual reasons prefer wild areas, while those who visit for grief prefer managed lawns. Spiritual experiences on cemeteries and visiting for nature predict accepting green development.

2. Cemeteries
...Are multidimensional places (Woodthorpe, 2011; Hornbogen, 2013) in the urban fabric and are crucial for biodiversity and
people. While their main function is burial and activities linked to mourning, they provide a range of
ecosystem services. (Francis et al., 2000; Hrsg. Kowarik et al., 2016)
They are important recreational, cultural
and historical places for people (Nordh et al.,
2017; Swensen, 2018).
They are also crucial habitats for a lot of urban
animals, plants and many endangered species
(Kowarik et al., 2016; Yilmaz et al. 2017).

3. Study area
Berlin holds 244 cemeteries distributed all over the urban fabric (Fig.
4). Most of them are designed in a park style with urban forest
patches (Skar et al., 2018; Kowarik et al. 2019).
Due to changing burial practices they differ in
● intensity of use
● management levels
● wilderness and successional process (Kowarik et al., 2016; Graf, 1986).
As Berlin grows many cemeteries are under pressure. There is
discussion to convert some of the cemeteries or areas within them
into green spaces (for recreation/leisure) or building land (e.g.
apartments/social infrastructure) (SenStadtUm 2014, Struchholz, 2019).

4. The aims of our study were to investigate the…
1. Acceptability for ‚grey development‘ (e.g. built structures), ‚green development‘ (e.g.
urban gardens) and acceptability of intensive leisure activities (e.g. playground)
2. Preferences for green areas on cemeteries differing in their level of wilderness
(ranging from mown lawns to overgrown areas)
3. Predictive potential of spiritual experiences on cemeteries, nature orientation
and reason to visit cemeteries on acceptability and preferences

(15 June 2020: 523 participants)
Closed questionaire addressing: reasons for visiting,
preferences, acceptability and predictors. Preferences and
accepatibility with photo stimuli.
Snowball sampling to Berlin citizens: institutions as
multiplicators, social media (e.g. facebook), leaflets with
QR- codes, online platform.

6. Preferences for management of
open green areas and of wild
elements (deadwood) on cemeteries
Concepts
Measured on a 5- point scale with photo stimuli (e.g.
mown lawns to overgrown areas with or without dead
wood)

appealing?’

13 different development strategies
could be grouped in three categories

‘On a scale from 1 (don’t accept at all) to 5 (totally accept), how acceptable are the
following development strategies for cemetery areas that are no longer used for
burial?’

9. Preliminary results
1. Acceptability for different
development strategies on
cemeteries
9
‘Green development’ was
significantly more preferred
than other development
strategies. ‘Grey development’
was the least preferred.
All significant different. Tukey’s HSD: Green-grey p < 0.001, green- leisure p < 0.001, grey-leisure p < 0.001
Fig 10: Acceptability of development strategies

10. Preliminary results
2. Preferences for how green areas
on cemeteries should be managed
10
Significant different. Tukey’s HSD: meadow-lawn p < 0.001, wild-lawn p < 0.001.
Areas with wilderness or meadows
with wildflowers were significantly
more preferred than mown lawns;
irrespective if with dead wood was
present or not.
Fig 11: Landscape preferences of management strategies. Since no differences were found
between scenarios with and without dead wood, photo sets were here combined.

11. Preliminary results
11
The reason to visit cemeteries for nature experiences, spiritual experiences on cemeteries and high nature
orientations showed all positive predictive potential to appreciated wild green areas and meadows with
wildflowers on cemeteries; however, the reason to visit a cemetery for grief showed negative predictive
potential on preferences for wild green areas.

experiences, nature orientation and reason for visit

4. Acceptability for different development strategies: predictive
potential of spiritual experiences, nature orientation and reason for visit
12
Spiritual experiences on cemeteries and the reason to visit cemeteries for nature experiences showed positive
effects on the acceptability of green development; while the reason to visit cemeteries for grief showed negative
effects. Nature orientations showed a negative effect on the acceptability of ‚grey development‘.
Fig 13: Predictive potential on acceptability of development strategies

13. Conclusion
Areas with wilderness or meadows with wildflowers were preferred above mown lawn;
irrespective if dead wood was shown on the photos or not.
People with high orientation towards nature, who visit cemeteries for nature experiences and
who gain comfort in experiencing nature on urban cemeteries (in our survey: spiritual
experiences) showed higher appreciation for wild areas or meadows with wildflowers on urban
cemeteries.
However, people who visit cemeteries for grief did not appreciate wild areas or meadows with
wildflowers.
Hence, it might be worth to manage areas differently (e.g. for grief and/or for nature
experiences) to meet the needs of visitors for cemeteries.

14. Conclusion
‚Green‘ (e.g. community gardens) was the most preferred development strategy for unused areas
on urban cemeteries while ‚grey‘ (e.g. buildings) was the least preferred one.
Similarly here, people who visit urban cemeteries to experience nature and who gain comfort in
experiencing nature on urban cemeteries were most supportive of ‚green‘ development, while
people who visit urban cemeteries for grief not.
Hence, urban areas with limited areas of green spaces, urban cemeteries should have a ‚green‘
development for people who appreciate nature and who can gain comfort on these special urban
places; this could contribute to environmental justice.
