1 Workshop on Landscape History Sopron, 22 April 2010
Landscape history analysis through the cartographic historical heritage: case study for Kozjansko and Pomurje regions, Slovenia Tomaž Podobnikar1,2,3 , Blaž Barborič4 1 School of Environmental Sciences, University of Nova Gorica, Vipavska 13, SI-5000 Nova Gorica, Slovenia 2Scientific Research Centre of the Slovenian Academy for Sciences and Arts, Novi trg 2, SI-1000 Ljubljana, Slovenia 3Faculty of Civil and Geodetic Engineering, University of Ljubljana, Jamova 2, SI-1000 Ljubljana, Slovenia 4Geodetski inštitut Slovenije, Jamova cesta 2, 1000 Ljubljana Workshop on Landscape History Sopron, 22 April 2010

2 Objectives Description of investigation area Methodology, outputs
Preliminary results of the project

3 TransEcoNet project regions

4 Southern region Associated initiatives (local, cross border,
3-country Nature Park: Goričko – Raab – Őrség 1996 – Raab 2002 – Őrség 2003 – Goričko Associated initiatives (local, cross border, transboundary) Slovenia: Biomura Hungary: National Park Őrség Austria: Nature Park Raab Europe: Natura 2000 Greenbelt

5 Slovenian part: Pomurje
the activities are carried out in the Pomurje region, Slovenia the spread of the invasive species Robinia pseudacacia the underlying causes and assess landscape scale ecological dynamics (e.g. Mura River floodplains, land use analysis in time series of last 200 years) in ecological networks the concept of place attachment and identification of the people with their landscape partners for the Pomurje PP14: University of Nova Gorica (UNG) PP15: Regional Development Agency Mura (RRA) AP20: Nature Park Goričko AP21: Scientific Research Centre of the Slovenian Academy of Sciences and Arts (ZRC SAZU)

6 Pomurje, Slovenia

7 Forests and natural heritage of Mura River

8 Methodology, outputs

9 Methodology, outputs WP4 multi-scale mapping of the history
comparison with the current status of ecological networks in Central Europe [Historical datasets of Mura River: (1) maps, plans, orthophotos, satellite images, (2) other material: photographs, topographic reports, tales/myths… (3) Methods: GIS, RS and statistic analysis, empirical approaches, multi-scale and multi-quality data analysis]

10 Preliminary results of the project

11 Preliminary results of the project
identification and mapping of the Robinia pseudacacia historical maps (spatial data sets) of Pomurje region for various applications land use changes analysis (time series: landscape reconstruction for the last 200 years) cooperation, harmonisation, other PPs

12 Riparian forest of River Mura
On the bank of the river grow floodplain forests, as Salicetum albae Fraxino-Ulmetum Genisto-Quercetum neophytic tree species Robinia pseudacacia Fraxino-Ulmetum Genisto elatae-Quercetum roboris Salicetum albae

13 Robinia pseudacacia Robinia pseudacacia (= tree)
native from Pennsylvania to northern Georgia and westward as far as Arkansas and Oklahoma introduced to Europe at the beginning of the 17th cent. flowers: early May, after the leaves it occurs on meadows and agricultural surfaces that are being overgrown it is invasive in mild climate as in the Pomurje region is (= natural expanding + plantation) most expanded in the region in 1980s affect of socioeconomic situation in the region (?) the vegetation in these regions has changed to such an extent that it cannot be classified into any forest community

14 Identification and mapping of the Robinia pseudacacia
Some criteria for recognition of the species: white flowers in spring (after leaves) lighter green colour comparing with floodplain forest… Data sources: sat. images: IRS-P6 (Indian Remote Sensing ~5 to 20 m), Landsat ETM and TM (30 m) from 1990s to today; lower spatial, higher spectral resol. contemporary orthophotos and aerial photographs starting from 1959 IR-orthophotos contemporary (and historical) maps, plans DEM/DTM (+ LiDAR) field work mapping, various land use data, Corine Land Cover, soil map… interviews with local farmers Methodology (RS, GIS and statistic techniques): reconstruction of R. pseudacacia-dynamics in the recent decade modelling the distribution of R. pseudacacia in relation to abiotic environmental factors and land use modelling (prediction) the expected distribution of R. pseudacacia in case of climate and land use change

15 Historical maps (spatial data sets) of Pomurje region for various applications
Outputs: - land use spatial data sets - study of Mura River changes (natural and anthropogenic) Data sets: - historical maps + LiDAR DTM + other documentation

16 Mura: Habsburg 1st military survey (Josephine)
1763–1787; 1 : commissioned by the empress Maria Theresa cause: Seven Years’ War against Prussia (1756–1763) no projection (maybe Cassini-Soldner), no coordinates that time exceptionality achievement graphical mapping – considerable deformations

17 Habsburg Franciscan cadastre (1 : 1440)

18 Habsburg 2nd military survey (Franciscan)
survey: 1817–1825, mapping: 1830– : applying trigonometric points for survey quality influence of producing of Franciscian cadastre 1823–1826 3 coordinate systems in Slovenia (+ 3 canters of geodetic surveys - datums): Krim (near o Ljubljana) Schöckl (near to Graz) Gellért (near to Budapest) coordinates, projection Cassini (transverse cylindrical projection) relief represented with hatching, after 1860 with contour lines

19 military map (1 : ) from 1869

20 Habsburg (Austro-Hungarian Monarchy) 3rd military survey
1869–1887; “special” 1 : ; optional: 1 : (survey was in this scale) and “degree” maps (“general”) 1 : horizontal and vertical network according to Mittel-Europäische Gradmessung Bessel ellipsoid 1841, every map sheet in own (stereographic) projection

21 Habsburg (Austro-Hungarian Monarchy) 3rd military survey, 1 : 75 000

22 Habsburg (Austro-Hungarian Monarchy) 3rd military survey, 1 : 75 000

23 Habsburg (Austro-Hungarian Monarchy) 3rd military survey, 1 : 75 000 from 1881

24 Habsburg (Austro-Hungarian Monarchy) 3rd military survey, 1 : 75 000 from 1894
regulation of Mure River! (first map where is this recognisable)

29 from ~1950 meanders finally disappeared

30 just some lethargies left

31 Presentation of area included in historical assessment (PP10)
Kozjanski Park covers an area of 206 sq km The biggest regional park in Slovenia 100% of area is protected, Natura 2000 areas represents 69% of total park, Special Protection Areas 2,3%

32 Presentation of area included in historical assessment (PP10)
Bistrica gorge Dry extensive grasslands High-trunk orchards

33 Map sources Historical assessment of Kozjanski park
1st Austrian military survey (1763–1787) – 1:28 800 3rd Austrian military survey ( ) – 1:28 800 Franciscan cadastre maps (1823–1826) - 1 : 5760 Rohitsch und Drachenburg (1943) – 1:75 000 Topographic maps (1951) – 1:50 000 Topographic maps (1971) – 1:25 000 Topographic maps (2006) – 1:50 000

34 Historical maps, orthophotos, land use: 1784-2009
5 4 3 6 Josephine military survey maps Franciscan cadastre maps Yugoslav maps Italian maps Aerial photographs

35 Georeferencing method
Josephine military maps and Franciscan cadastre maps were first combined and later georeferenced

36 Different legend keys Josephine military topography
Franciscan cadastre Italian 1:25,000 Yugoslav 1:25,000 transitional woodland shrub forest bare rocks urban fabric pastures inland waters

37 Quality and time series

38 Backward editing method (“reverse engineering”)

39 Land use changes 1800 1930 2000

40 Focus and investigation areas that are included in historical assessment
Kozjanski Park covers an area of 206 sq km Investigation areas: Bistrica gorge Dry extensive grasslands High-trunk orchards

41 Results - vectorized layers

42 Results - analysis

43 Results - analysis

44 Land use/land cover legend for assessing landscape dynamics
1 Travniki Grassland Polygon 2 Vinogradi Vineyards 3 Gozd Forest 4 Urbana območja Urban areas 5 Sadovnjaki Fruit trees According to comparison of the legends obtained from different map sources 5 polygons were established

45 Dynamics of change of land cover – changed/unchanged areas
Similar changes of landcover periods from 1780 to 2006

46 Stably used areas from 1780 - 2009
Forest and grassland are main unchanged landuse classes

47 Dynamics of change of land cover

48 Landscape dynamics Vectorized layers were overlaid
Sliver poligons were produced and eliminated using ArcGIS tools Trajectories of change were calculated
