4 Palynological research in the Vosges

Mountains: a historical overview

Figs. 4 and 5 and table 1 show the palynologi-

cally analysed sites from the Vosges Mountains

known to the present author.

The first palynological analyses from the area

originate from the Champ-du-Feu mire and were

published around 85 years ago (

D

ubois

& H

att

1930a). In a publication of the same year,

D

ubo

-

is

& H

att

(1930b) also refer to investigations of

the Tourbière de la Maxe and of Sutt (Soutte),

however without presenting the pollen diagrams.

Seven years later three further papers appeared

(

D

ubois

& D

ubois

1937,

H

att

1937,

O

berdorfer

1937). In those early days, palynological research

focussed on forest history, and pollen diagrams

displayed only few pollen types attributable to

trees and incidentally some types attributable to

herbs. The sample interval was generally large,

resulting in a low temporal resolution. Excep-

tions are the diagrams from the Ohnenheim and

Urbis sites by

O

berdorfer

(1937), which partly

have a resolution of 2-5 cm. Although the value

of these early pollen diagrams seems somewhat

restricted compared to the present-day scientific

standard, they provide valuable information on

phases of mire development.

In the 1940-ies, six mires were studied by a re-

search group headed by

F

ranz

F

irbas

, of which

the results were published after World War II (

F

ir

-

bas

et al. 1948). This research represents a ma-

jor breakthrough in the development of palyno-

logical science: a considerable amount of pollen

types, including types produced by herbaceous

plant taxa, was presented with a high temporal

resolution. The pollen curves were displayed as

single curves next to each-other in contrast to the

general use at that time of crossing and overlap-

ping lines. This resulted in a clear picture of re-

gional vegetation development since the Weich-

selian Lateglacial. For the first time,

F

irbas

used

his concepts of pollen zones which he shortly

afterwards described elaborately in his books on

the forest development north of the Alps (

F

irbas

1949, 1952). Detailed descriptions of sediment/

sedentate layers and their macrofossil content

provide additionally valuable data on local mire

development. In this sense, the publication of

F

ir

-

bas

et al. (1948) was probably the most advanced

palynological study of its time.

From the nineteenfifties, no publications on the

vegetation history in the Vosges Mountains are

known to the present author. In the following de-

cades various palynological studies appeared.

The work of

L

emée

(1963) provides many scientific

statements that are, however, hardly supported by

his pollen diagrams.

D

resch

et al. (1966) present

four pollen diagrams from the Grand Ballon regi-

on that allow a good reconstruction of the Holo-

cene vegetation history. The study of

T

eunissen

&

S

choonen

(1973) presents a high-resolution pol-

len diagram covering the Weichselian Lateglacial.

D

urand

& G

uillet

(1966) – although presenting re-

lative coarse pollen diagrams – bring the research

of vegetation history of the Vosges Mountains to

a higher level by introducing the use of radiocar-

bon dates. Other research by

G

uillet

(1968, 1970,

1971a/b) concentrates on the development of ter-

restrial soils. Due to differences in pollen preser-

vation processes, it is difficult to directly compare

pollen diagrams of soils with those of peat (cf.

M

unaut

1967,

H

avinga

1974,

A

ndersen

1986), but,

on the other hand, soil profiles provide valuable

information on local vegetation history of dry soils

that cannot be inferred from the regional pollen

deposition in the centres of large wetlands.

In 1966, an interdisciplinary study group (“Werk-

groep Vogezen”) from Utrecht University started a

long-term palynological research project in order

to study vegetation history at different altitudes and

indifferent landscape units (

J

anssen

1974,

J

anssen

et al. 1985). The research concentrated on a ca. 70

km long and 30-40 km wide belt across the moun-

tains, yet also some sites further to the north have

been investigated. Under the motto “The present is

the key to the past”, the project also included the

study of present-day vegetation in order to better

understand and interpret fossil pollen sequences.

An important tool was the analysis of palynological

surface samples from various vegetation types on

a micro- (small typical areas) and a macro-scale

(the various vegetation types of the complete

mountain range) (

ter were taken into account (

& W

vegetation of the Kastelberg area (

the Goutte Loiselot mire (

E

1985) and the

Foret de la Bresse (

K

1985), whereas a fourth

PhD-thesis described in great detail actual mire

vegetation (

B

ick

1985). Apart from these, a large

variety of smaller publications appeared (table 1).

Also a number of MSc-theses from Utrecht Univer-

sity deal with the vegetation history of the Vosges
