BACKGROUND AND OBJECTIVE
In connection with an Environmental Impact Assessment of extraction of raw materials from the
forest of Kirkeby Vænge, a conservation plan for Dormouse (Muscardinus avellanarius) has been
developed /1/. The dormouse is included in the EU Habitats Directive article 12 on strictly protected species and is listed on the Appendix IV of the Directive. The objective of the conservation
plan is to preserve the population of dormouse during and after the extraction of raw materials.
The extraction of raw materials is planned to take place over a period of 20 years and is expected
to result in formation of 2 lakes /1/. Extraction was started in 2009.
The conservation plan consists of 6 phases, and it is an important principle, that the compensating measures for extraction of a specific area should be implemented and functioning at the beginning of extraction of the area in question.
The compensating measures have as goal to

preserve and strengthen the system of corridors in the area for living and dispersing of
dormouse before, during and after extraction of materials in the area.

to preserve and extend coherent living areas for the dormouse in the project area before,
during and after extraction of raw materials

to establish a robust and coherent net of corridors and “core” areas in the long term in
the area.
The measures consist of improving existing suitable and non-suitable living places (forest parts,
forest edges, corridors) by thinning and cutting of closed forest and planting of hazel, raspberry,
bramble, honeysuckle, spruce etc., together with setting up of nest boxes, and to re-establish living places after extraction as corridors, shore vegetation belts and other vegetated areas.
The objective of the monitoring is

to provide documentation for presence of Dormouse in existing, new and improved habitats and

to measure quality of new/improved habitats.
The monitoring program was developed in connection with the conservation plan /2/. The monitoring program is foreseen to be evaluated generally after 5 years. This working report describes
the activities and the results of the first 3 years of monitoring, 2007, 2008 and 2009.

METHODS
2.1
Habitat improvement
According to the conservation plan for the Dormouse (Muscardinus avellanarius) in Kirkeby
Vænge /1/, activities for improvement of habitats have been carried out in 2007 (Table 2.1). In
2008, some of the activities have been followed up, for example by supplementary planting in selected areas. In 2009 no new activities was implemented.

4) Actual year for implementation of activity
It is expected, that 2 years, in case of larger areas with clear cutting 3-4 years, will pass before
the locality is suitable as living place for dormouse.
2.2
Dormouse monitoring
Nest boxes are suitable for improving living conditions of the dormouse by offering nesting possibilities, but are as well suitable for monitoring purposes. In 2007, specially designed nesting boxes (see Attachment 3) were placed 1-2 meters above ground and fixed by means of a bicycle
rubber tube (Fig. 2.2.1). The boxes were numbered sequentially for the monitoring purposes. In
2008 the rubber tubes were in many places substituted by plastic clips, as the rubber tubes were
not persistent to disintegration, causing many boxes to fall to the ground.
One important goal of the monitoring in 2007 was to find out, if the nesting boxes were accepted
by the dormice in the area. The results from 2007 indicated, that this was the case /3/.
Therefore, the nest boxes program was continued in 2008. Additional nest boxes were set up in
area 1, 2, 3, 6, 7, 9, 10 and 16. In 2008 altogether 251 nest boxes were available for the dormice in the area. The boxes were checked 8th October and 12th November. In 2009 the nest boxes were checked 9th October and 15th November.
The checked nesting boxes were classified as following:
1. Nest boxes having been occupied by dormouse. The box contained nest of dormouse, which is
rounded and firm, and contain both leaves of grass and broad leaves (see Fig. 2.2.2). A few were
occupied by 1-2 living dormice (fig. 2.2.5).
2. Nest boxes being occupied by Apodemus sp. The nest consists of a loose gathering of broad
leaves without grass leaves and without rounded shape. The nest box is most often wet in the
bottom due to urination and with chewing marks around the entrance hole (Fig. 2.2.4). Some of
the boxes contained up to seven Apodemus mice (Fig. 2.2.3).

RESULTS
3.1
Habitat improvement
As described in Chapter 2.1, habitat improvement was carried out in a number of localities in
2007 and 2008 pointed out in the conservation plan /1/. Details on cutting and planting are provided in Attachment 2. The appearance of the localities in 2007, 2008 and 2009 after implementation of activities is documented in the following with photos, accompanied by a brief description
of the present state. The area’s suitability as a living place in 2008 is assessed according to the
principle described in /1/.
Area 1
2007
1-7
Fig. 3.1. 1. Area 1, 2007. A corridor has been made by cutting a monoculture of 80 year old
beech forest and replanting with hazel, honeysuckle, common hawthorn, blackthorn, guelder
rose and oak. Distance between plants was 1 meter and between rows 2 meters. There is poor
developed bottom vegetation. The photo is taken from the eastern part of area 1 towards
west. The area has been fenced to avoid damage on the new plants from e.g. roe deer.
2008
Fig. 3.1.2. Area 1, 2008. Same view as in Fig. 3.1.1 photographed 24.09.2008. The beech
stand on the right has been cut in early spring 2008. The growth of planted species appears to
be slow, and there is competition from grass species as wavy hairgrass (Deschampsia flexuosa). In the foreground a hazel plant, app. 50 cm high. Further, scattered specimens of honeysuckle and guilder rose were found. The area seems to be exposed to wind and shade.
2009
1-8
Fig.3.1.3. Area 1, 2009.The light area to the right is the barren sand and gravel, ready for extraction. Compared to 2007 and 2008 the bush layer has developed further with natural colonization by raspberry and birch, growth of hazel in progress and survival of guilder rose, honeysuckle and hawthorn.
The area in its present state is assessed as moderately suitable as living place for dormouse.
In connection with extraction of materials, a protecting wall of app. 1 m height has been established along the northern side of area 1 to protect the plants from wind impact. It is assessed, that this activity has facilitated establishing of a bush layer at the locality. To the north
of the area extraction of raw materials has started (Fig. 3.1.4).
Fig.3.1.4. Extraction of raw materials in forest compartment 110 and 111.
Area 2
2007
Cutting and planting has taken place. See Attachment 2
1-9
2008
Fig. 3.1.3. Area 2, 2008. After the cutting, the ground is some places barren due to coverage
of bark from the cut trees. The planted bushes and trees is growing scattered and slowly, with
a few hazel and honeysuckle, not exceeding 50 cm in height. Grasses dominated by the wavy
hair grass Deschampsia flexuosa have invaded the area. To the north there is growth of bramble, which will probably spread into the area.
2009
Compared to 2008 natural colonization by raspberry, birch and willow is in progress. The
planted species of hazel, honey suckle and guilder rose survive, but in rather poor condition.
The area in its present state is assessed as not suitable as living place for dormouse
Area 3
2007 : Only planting activities has taken place
2008: A belt parallel with the gravel road at about 50 meters distance has been cut, probably
in 2007 (see Fig. 3.4).
1-10
Fig. 3.1.4. Area 3, 2008. Corridor parallel with the gravel road at the entrance of the landfill.
There is a rather well developed bush layer of birch, ferns and bramble.
2009
Fig. 3.1.5. Area 3, 2009. Rapid regrowth of Common Alder (Alnus glutinosa) and willow in the
corridor parallel with the gravel road.
The area in its present state is assessed as suitable as living place for dormouse.
Area 4
2007: Cutting and planting activities has taken place. The area was not inspected.
2008: The area was not inspected.
2009
1-11
Fig. 3.1.6. Area 4, 2009. The south western part of area 4 consists of approximately 5 m tall
Beech mixed with Birch and Alder Buckthorn. The bottom is covered with Bramble and Bracken
fern (Pteridum aquilinum. In the picture there is a little marshy area. This part of area 4 is assessed as moderately suitable.
Fig. 3.1.7. Area 4, 2009. The southern part of area 4 consists of a mixture of trees, dominated
by spruce, birch, and with bottom cover of Bramble and Bracken fern (Pteridum aquilinum)
and Soft Rush (Juncus effusus), indicating poor soil. This part of area 4 is assessed as moderately to not suitable due to lack of food plants.
1-12
Fig. 3.1.8. Area 4, 2009. Eastern part of area 4 was clear cut and replanted with Hazel, Guelder rose, Rowan, Honeysuckle in 2007. In 2009 the Rowan was about 2 m tall, hazel about 1,5
m and the others ½ meter. Bramble is dispersing in the bottom. Invading Birch has been cut
and Soft Rush has been mown. This part of Area 4 is assessed as moderately suitable.
Fig 3.1.9. Area 4, 2009. Northeastern part of Area 4, forming the Eastern border of the forest
with Bramble, Hawthorn, Elderberry and herbs. In this specific area no activities have been
carried out. The area is assessed as suitable for dormouse.
Area 5
2007
1-13
Fig. 3.1.10. Area 5, 2007. The closed cultivation of Sitka spruce on the slopes around the lake
in the eastern part of the forest was clear cut and replanted with hazel, honeysuckle, common
hawthorn, blackthorn, guelder rose and oak. Only a few, scattered trunks were left. There is
some undergrowth of brambling, raspberries and birch.
2008
Fig.3.1.11. Area 5, 2008. In area 5, there was in 2008 found different degrees of regrowth,
varying from patches of birch trees and bush of bramble to grass dominated areas. Broom
seems to spread in the area by natural way. The planted species has varying degree of success, but f.ex. Guelder Rose seems to grow well.
2009
1-14
Fig.3.1.12. Area 5, 2009. The natural regrowth by Birch and Broom continues, and Hazel, honeysuckle and Guelder Rose are growing slowly, not exceeding a height if about 0,5 m.
The area in its present state is assessed moderately suitable as living place for dormouse, depending on the exact location.
Area 6
2007
Fig. 3.1.13. Area 6, 2007. The oaks in Area 6 have been thinned but there has been no replanting. In the area there is some undergrowth of brambling, varying through the area.
2008
In 2008 the situation is more or less the same, except that the bramble has grown higher. The
area in its present state is assessed as suitable as living place for dormouse.
1-15
2009
Fig. 3.1.13. Area 6, 2009. In the thinned areas, Bramble growth is continuing, some places reaching heights
of 1,5 – 2 meters. The Bracken fern (Pteridum aquilinum) is dominating in patches, and generally, lianas in
the form of honeysuckle is common in the oaktrees. The area in its present state is assessed as suitable as
living place for dormouse.
Area 7
2007
Fig. 3.1.10. Area 7, 2007. In area 7 some trees of Sitka spruce and Nobilis spruce were
thinned. The herb layer was sparsely developed, mainly consisting of some ferns. Further, there was some growth of young trees.
2008
1-16
Fig. 3.1.11. Area 7, 2008. The herb layer is still sparsely developed, mainly consisting of
ferns.
2009
There were no significant changes in herb layer compared to 2008. The area in its present
state is assessed as moderately suitable as living place for dormouse.
Area 9
2007
Fig. 3.1.12. Area 9, 2007.The area was clear cut and replanted with hazel, honeysuckle, common hawthorn, blackthorn, guelder rose and oak. New plants can be seen to the right in the
photo. In the centre, the area is rather boggy and probably not very suitable for dormouse. In
the periphery, the area is drier with some scattered herbs and undergrowth.
2008
1-17
Fig. 3.1.13. Area 9, 2008. The photo is taken approximately the same place as Fig. 3.1.12. Before clear cutting, area 9 consisted of a drained swamp, densely overgrown by a monoculture
of spruce. After clear cutting, the centre of the area has become boggy again with water
logged areas. The outer part of the area has been replanted with among others oak and rowan, which seem to get established. Herbs are starting to appear, mainly grasses, ferns and
soft rushes.
2009
Fig. 3.1.14. Area 9, 2009. Compared to 2008, Birch and Rowan are growing well. Spruce, Oak,
Broom and Hazel are growing more moderate. The herb layer is developing with Remote sedge
(Carex remota), Soft Rushes, Wavy Hairgrass and others.
The area in its present state is assessed as becoming moderately suitable as living place for
dormouse.
Area 10
1-18
2007
Fig. 3.1.15. Area 10, 2007. The area was clear cut and replanted. The photo is taken towards
west with a little pond to the right in the picture. The ground is still nearly without vegetation.
However, to the south west some existing bramble scrub is extending to the north east.
2008
Fig. 3.1.16. Area 10, 2008. Area 10 seen from the gravel road towards the east. The little
pond is seen to the left in the picture.
2009
1-19
Fig. 3.1.17. Area 10, 2009. Invading Bracken fern, Birch and Raspberry are developing quickly, while the planted species do not grow. Probably the soil are not suitable (too acid), indicated by some of the species of herb and bushes.
Along the edge of area 10 there is a more diversified layer of herbs and bushes with bramble,
grasses, soft rushes, rowan, birch and others, making the locality more suitable as living place
for dormouse.
The area in its present state is assessed as not suitable to moderately suitable (along the
edges) as living place for dormouse, depending on the location.
Area 12
Only nest boxes set up.
Area 13
2007
1-20
Fig. 3.1.18. Area 13, 2007. The bush layer has been developed within half a year in the northern part of the area with bramble covering the bottom and growth of herbs.
Fig. 3.1.19. Area 13, 2007. Along the southern edge of the area 13, there is some proliferation
of bramble from the forest edge towards the railway track. The herb vegetation is only moderately developed.
2008

Fig. 3.1.21. Area 13, 2008. Along the southern edge of the area 13, there is some proliferation of bramble from the forest edge. The herb vegetation is only moderately developed. The
planted species of hazel, rowan and guelder rose show moderate growth, 0,5 to 1 meter.
Herbs were dominated by tufted hairgrass, remote sedge and soft rushes. Also beech, black
elderberry and honeysuckle were found.
2009
1-22
Fig. 3.1.22. Area 13, 2009. Hazel and Bramble continue to grow fast (compare Fig. 3.1.18 and

Dormouse monitoring
The nest boxes were checked on 9th October and 15th November 2009. The results are outlined in
Table 3.2.1 and compared to the results from 2007 and 2008.
Of the 249 nest boxes, 19 contained nests of dormouse. 67 nest boxes were inhabited with Apodemus mouse. The results are shown in the map in Attachment 1b.
Approximately 10 % of the nest boxes had disappeared, fallen down or was not properly fixed.

Table 3.2.1. Results of monitoring of nest boxes.
The following comments can be given to the specific areas:
In area 1, the nest boxes were empty. This is probably due to a combination of unsuitable living
conditions and lack of suitable places to install the nest boxes.
In area 2, 1 nest box was inhabited by dormouse. Although the main part of the area appears
unsuitable as living place, the area borders to the slope down to the landfill. The edge and the
slope have a dense bush layer dominated by bramble, and the nest box is placed in a small tree
near this growth.
In area 3, the nest boxes were located 2-3 m from the gravel road at the landfill in a bushy area
with bramble and small trees, assessed as suitable for dormouse. Three of the boxes contained
nests of dormouse, and 2 were inhabited by Apodemus.
In area 6, which is a light open oak forest with undergrowth and lianas of honeysuckle and rather
well developed growth of bramble, no nest of dormouse was found in the nest boxes and not less
than 23 boxes were inhabited by Apodemus. Many of the boxes contained 2 or more individuals,
up to 7 were found in one box. 2 of the boxes were filled with acorn. Generally, Apodemus mice
seem to be numerous in 2009 and 2008 compared to 2007.
The extremely big occurrence in locality 6 may be due to a high number of acorn in 2009 and
2008. The locality is assessed as suitable for Dormouse, as it is rich in bramble and lianas of Honeysuckle, but the Apodemus is apparently capable of displacing the Dormouse from the nestboxes. It is assumed that the Dormouse instead is building nests in the vegetation of Bramble.
In area 7, where Sitka and Norman’s spruce were thinned, two nest boxes with Dormouse nests
was found, compared to 1 in 2007. The boxes were found in an already vegetated area.
In area 12, all nest boxes with dormouse nests were both in 2007 and 2008 located in the area
west of the gravel road Dyrehavevej. In 2009, in addition two boxes were found east of the gravel road. Area 12 is in /1/ is considered as an optimal locality with well developed growth of
bramble and where earlier a nest were found in bramble /1/. In 2009 9 nests were found, making
this locality the best for Dormouse in the investigated area.
The number of nest boxes with Apodemus mice were 11 in 2009 compared to 10 in 2008 and 6 in
2007. On the eastern side of the gravel road Dyrehavevej no dormouse nests were found in area
12 in 2007 and 2008, but two were found in 2009. This area has less developed Bramble vegetation and has poor developed undergrowth where the nest boxes were set up.
Area 13. This area represents a long forest edge along the west and to the south, particularly to
the south along the railway a varied bush layer including bramble is occurring. One nest of
Dormouse was found in the southern forest edge. The number of boxes with Apodemus mice was
20 in 2009, compared to 10 in 2008 and 1 in 2007. Particularly the western forest edge together
with area 14 is assessed to become a valuable extension of the core area 12 in a very few years
because of the fast regrowth with bushes herbs and small trees.
1-29
Area 16. The area constitutes relatively narrow forest strips10-30 m along the relative busy
paved road Vængevej with composition varying from young beech forest to older pine forest with
scarce undergrowth. At the bottom of the slopes, bordering to the alder swamp, rich vegetation
of Bramble has developed, making parts of the locality suitable for Dormouse. There was found 3
nests of dormouse in 2009, compared to 1 in 2008 and 5 in 2007, whereas the Apodemus mouse
occurred in 11 boxes compared 9 in 2008 and 1 in 2007. Again, Apodemus seems to occur in
greater number in 2009 and 2008 compared to 2007.
It may in this locality, as in locality 6, compete with dormouse for space in nest boxes, at least
outside the breeding season. Normally, Apodemus breeds in subsoil path systems /4/. In Table
3.2.2, the results of monitoring of nesting boxes are compared with suitablilty of surroundings as
living place. Generally, inhabited nest boxes were found at suitable localities, or at the edge of
moderately or not suitable localities.

Fig. 3.2.1. Nest box with dormouse nest in area 6. The locality consists of middle aged oak with lianas of honeysuckle and a scattered undercover of ferns and bramble.
The results of the monitoring 2007, 2008 and 2009 show that

Development of improved habitats is progressing.

Some habitats show rapid improvement, others have only a slow progress. A map on
improvements is shown in Attachment 1b

The nest boxes are used by the Dormouse as nesting places both years.

The dormouse is widespread in the area, but there seems to be a core area in the north
western part of Kirkeby Vænge. The results of the monitoring in nest boxes show approximately the same distribution the two years.

The nest boxes make breeding possible in suboptimal places, i.e. in places where bramble
is lacking or poor developed, making the localities less suitable as nesting places. Nest
boxes therefore helps to increase the population

Dormouse can build nests quite close to roads with traffic.

Nest boxes can be used as a monitoring tool.

Apodemus was very numerous in 2009 and 2008, with 67 and 58 boxes occupied, respectively. The reason might be occurrence of big amounts of acorn through 2006 to
2009.

Apodemus seems to be able to displace Dormouse from nest boxes in otherwise optimal
localities, if there is plenty of food available to Apodemus.

EVALUATION AND RECOMMENDATIONS
4.1
Habitat improvement
2009 was the second year after habitat improvement, where the main activities took place in
2007. The state of the improved areas has been documented with photos and a short description.
The habitats have improved in varying degree, from establishing of a rich undergrowth and bush
layer with bramble, hazel and herbs, suitable for dormouse, to a very slow regrowth. Degree of
clear cutting, size of area and exposure for wind and sun as well as soil conditions seem to be
among the factors affecting regrowth. It is recommended to follow the development of the vegetation yearly to assess if additional planting or other activities is necessary.
In Area 1 a protection wall along the northern side, to protect the area from wind was carried out
in December 2008.
In a few years it is recommended to evaluate, if additional thinning or other measures in the improved areas will be necessary.
4.2
Dormouse monitoring
In 2008, 48 nest boxes were additionally installed, primarily near areas to be improved. No additional boxes were installed in 2009.
Generally, the setting up of nest boxes showed, that the Dormouse both years used the nest
boxes produced, and that the Dormouse seems to be widespread in the area. There seems to be
a core area in the north western part of Kirkeby Vænge. Particularly in areas where the habitat is
assessed as not suitable, there is few or no dormice in the boxes.
The results of the monitoring in nest boxes show approximately the same distribution three
years. In 2008 and 2009, Apodemus was much more numerous than in 2007, probably due to
rich acorn and beech nut years 2006, 2007, 2008 and 2009. Probably, the Apodemus invade the
boxes after breeding season. There is probably an overlap in time, where the two species compete about the space in the boxes.
The nest boxes are controlled and if necessary cleaned every year.
In 2009, the inspection was carried out from the beginning of October to middle of November. In
the first inspection round there was still dormouse in a few boxes, while in November they had
moved to the ground for over wintering. In November, perhaps more Apodemus has invaded the
nestboxes. The best time for inspection must be a compromise between avoid disturbing the
dormouse and avoid that too many Apodemus invade the boxes. It seems that during favorable
conditions for Apodemus, this species can displace the Dormouse from the boxes

Formålet med ekskursionen var, at få input fra Det Grønne Råd til hvordan kommunen
bedst anvender og driver/plejer kommunens egne grønne områder, skov og natur –
og dermed også en optakt til næste ordinære møde.
Kommunen ejer ca. 100 ha parker og grønne områder samt 272 ha skov og natur –
fordelt på 150 lokaliteter.
Vi besøgte fire lokaliteter, der illustrerede forskellige problemstillinger.
2
Grønt areal ved Ollerup Sø
11 ha, der i dag primært ligger som slået græs/græsplæne (15-20 slåninger pr. år)
med tætte holme af træer og buske samt § 3 mose mod nordøst. Der er adgang til
søen. Kommunen har frigivet fiskeretten til alle, der har det nationale fisketegn.
En aktiv grundejerforening holder sti og bådebro. Grundejerforeningen ønsker at
indgå i udarbejdelse af en pleje-/udviklingsplan for området.
Forslag/kommentarer fra Rådet:
Fjerne nogle af holmene af træer og buske, andre holme ryddes for krat,
højstammede træer lades stå (landskabselement og klatretræer), og der skabes
mulighed for at ”se gennem beplantningen” – også af sikkerhedsmæssige hensyn.
Dele af området hegnes og afgræsses med kreaturer f.eks. galloway (små og rolige
dyr) for at fremme naturindholdet. Alternativt eller i kombination hermed kan områder
lades urørt med klippede stier gennem. Stierne flyttes fra år til år.
Der bibeholdes boldbaner og andre opholdsarealer som slås, arealer til hundeluftning
samt kælkebakke.
Overveje løbesti, udendørs motionsredskaber.

Vi mødte formanden for grundejerforeningen. Han var positiv overfor ændringer på
området, og mente at der kunne være basis for et kogræsserlaug i området.
Ny grøn kile i industriområde øst (ved Englandsvej)
Der er anlagt et regnvandsbassin med dykket udløb. Området rummer gode
overdrevsplanter. I den østlige del af industriområdet findes en mindre skov, der nu
ejes af kommunen. Området rummer formentlig springfrø.
Supplere regnvandsbassinet med et mindre vandhul, der tørrer ud om sommeren.
Dette vil hindre, at der kommer fisk i vandhullet og sikre overlevelse af frøernes
haletudser.
Der bør anlægges en sti gennem området til at styre færdslen og evt. platform ved/i
bassinet.
Der bør kun plantes få træer om nogen på området – for at sikre de lysåbne forhold.
Træbeplantninger i et industriområde kan ske som holme eller bånd, der kan bryde
bebyggelsen og samtidig give virksomhederne mulighed for frie facader.
Der kan sejles med modelbåde i regnvandsbassinet.

Ørkild Voldsted.
Kulturarv og natur midt i byen - specielle krav til plejen. Vest for voldstedet løber
Trappebækken og øst for Kobberbækken. Begge vandløb har fine fysiske forhold.
Mølledammen syd for voldstedet er sandet til – blev senest oprenset i 2001 (2.500
m3) – skal kommunen prioritere dette igen? En oprensning kan blive bekostelig fordi
der kan forventes at være forurenende stoffer i slammet. Kommunen har en del
gadekær, som også trænger til oprensning – skal dette prioriteres?
Voldstedet blev ryddet i begyndelsen af 1990-erne og har efterfølgende været
afgræsset i perioder. I perioder uden afgræsning groede arealet til i brombær og
bøgepur. Dette blev ryddet i 2008, der blev sat nyt hegn og området har siden været
afgræsset. Afgræsning kan kun ske med får for at undgå skader på fortidsmindet. Det
ser ud til at fårene nu kan holde området i en god naturtilstand.
Området bør igen formidles ved skiltning.
Der var tilslutning til, at kommunen fjerner de 6 store platantræer, der står syd for
voldstedet og tager udsigten fra toppen af voldstedet og ud mod havnen og sundet.
Åbne op på strækninger af Kobberbækken så man kan opleve vandløbet, etablere sti
+ sætte et par bænke op, hvor vandløbet risler.

Kommunen bør – i de bynære skove - være opmærksom på sikkerheden omkring ask
med toptørre (en svampesygdom).
Hallindskov/Gl. Hestehave og grusgraven ved Stevneskoven.
Vi gik fra parkeringspladsen ved Hestehavevej, ind gennem Gl. Hestehave til
Hallindskoven, ad Stevnevej til grusgraven og gennem Stevneskoven.
Gl. Hestehave har været frugtplantage indtil 1970-erne, hvor Svendborg Kommune
overtog arealet. Området rummer en rig kulturhistorie med mange gravhøje.
Kulturarvsstyrelsen har valgt at lade bronzealderbygden i Gl. Hestehave være en
central lokalitet i fortællingen om Danmarks Oldtid og har i 2011 opsat skilte i
området med formidling af kulturhistorien, omlagt en vej og oprenset den lille
hellekiste. Svendborg Kommune har slået vegetationen på højene + stier og tyndet ud
i beplantningen i skoven så man bedre kan se højene.
En landmand tager ét slæt hø om året på det åbne areal. Herved fjernes
næringsstoffer fra arealet og udvikling af overdrev fremmes.
Det åbne areal bruges som ”hundeskov”, hvor hunden løber frit. Det er kommunens
oplevelse, at denne benyttelse af området ikke giver anledning til konflikter – har kun
6
modtaget en enkelt klage gennem de seneste år. I skovene skiltes med, at hunde skal
føres i snor.
De rekreative og naturmæssige værdier prioriteres højere end den forstlige drift af
kommunens skove. Der har i 2011 været en besparelse på skovbudgettet, der nu er
på ca. 250.000 kr.
Grusgraven ved Stevnevej er levested for bilag IV-arten Markfirben – to levesteder
blev udpeget – kræver sandede solvendte skrænter med sparsom beplantning til
temperaturregulering (sol/skygge), fødesøgning og skjul.
Grusgraven bruges af mountainbike-cyklister. Svendborg Kommune har holdt møde
med formanden for Mountainbike-klubben i Svendborg og med Skolerne i Oure. Fra
begge steder er der forståelse for områdets værdier, og at de kun kan køre på
etablerede stier.
Der var opbakning til kommunens nuværende drift af skovene. Det bør også være
muligt at tjene penge på skovdriften.
Kan arealet afgræsses med kreaturer? – nej som på Ørkild Voldsted vil kreaturer
ødelægge fortidsminderne. Hvad med får?
Det tager mange år før der udvikles en værdifuld overdrevsvegetation på grund af
næringsstofpuljen i jorden – i år vil der kunne tages endnu et slæt.
Løse hunde kan være et problem for øvrige brugere af området.
Hundeskove er populære og efterspurgte – måske finde en anden lokalitet, som kan
hegnes eller indhegne et mindre areal i området.
Bevoksningen med douglasgran i Hallindskoven bør først fældes når den er 80 år –
her yngler Grønspætte som et af de få steder på Fyn.
Rødgranbeplantninger bør fældes.
Naboerne har vetoret over anvendelsen af grusgraven – hindrede at Naturskolen
kunne sætte to shelters op.
Det opleves, at mountainbikere kører uden for stierne både i grusgraven og i
Stevneskoven – der var enighed om, at stier i denne sammenhæng er, hvor
almindelige cykler kan køre.
Det største problem med mountainbikere er gener for andre brugere af området.
