Species and synonym list of the German marine 

macroalgae based on historical and recent records 

Arten- und Synomliste der Makroalgen in den Deutschen Küstengewässern – 

Auswertung von historischen und rezenten Befunden 

Abstract 

A summary of all macroalgal records to occur in the German water bodies of 

the North Sea and the Baltic Sea during the last 190 years are presented, with their 

synonymes. All available literature and herbarium collections were revised and a 

potential species list was compiled. Therefore, the list reflects the sum of all records 

between 1819 and 2008 and not the actual presence of macroalgae along the 

German coast. 469 species have been recorded since 1819 including insecure 

registrations and single observations. Species richness decreases rapidly from the 

subtidal areas and the rocky shore of Helgoland to the brackish waters of the Baltic 

Sea with its often instable sediments. 322 species have been registered for 

Helgoland whereas the Western and Eastern part of the German Baltic Sea does not 

contain more than 211 and 181 species respectively. For the North Frisian Wadden 

Sea and the East Frisian Wadden Sea, 113 and 112 species have been registered, 

respectively. In relation to species number red algae are most abundant around the 

island of Helgoland, followed by brown and green algae. In the Frisian Wadden Sea 

green algae are most common, whereas in the Baltic Sea filamentous brown algae 

gain in importance. The presence of neophytes increased during the last decades, 

but total number does not exceed 10 species. The red algae Callithamnion 

teragonum, Halurus flosculosus and Neosiphonia harveyi are the latest new species 

records from Helgoland whereas Gracilaria vermiculophylla is the latest new species 

recorded in the German Wadden Sea and the Baltic Sea since 2004.

Introduction 

Salinity and its variability, substrate availability and light climate are the key 

factors governing the distribution of macrophyte species along the German coast 

(LAKOWITZ 1929, KORNMANN & SAHLING 1977, NIELSEN et al. 1995). They can explain 

together with local hydrodynamic conditions and biological factors the main portion of 

species distribution (BUCAS et al. 2007). 

In the last decades changes in distribution and diversity of macroalgae were 

observed in German coastal waters. All water bodies bordering the German states, 

Lower Saxony, Schleswig-Holstein, Mecklenburg-Western Pommerania and their 

corresponding islands have been subjected to extremely high anthropogenic impacts 

in the 20th century (ŁYSIAK-PASTUSZAK 2000; REISE et al. 2006). The nutrient input to 

the coastal waters is high, especially via rivers and diffuse agricultural run-off 

(BEHRENDT et al., 1999; STALNACKE et al. 1999). Consequently, the trophic status has 

increased drastically during the last thirty years according to long-term monitoring 

measurements (Nausch et al. 1999). The underwater light regime as well as the 

substrate type have changed over time depending on the eutrophication of the water 

bodies (SCHUBERT & FORSTER, 1997; NIELSEN et al. 2002). Both factors are important 

for the composition and depth distribution of submerged macrophyte communities 

(Van den Berg et al. 1998; GREVE & KRAUSE-JENSEN 2005; HAUXWELL et al. 2006) and 

explain observed changes in all regions. 

The arrival of new species from warmer regions and the invasion of alien 

species due to human activities can increase species diversity on the one hand, but 

risk dramatic changes in community structure on the other. Climate change 

enhances the arrival of new species from warmer regions that formerly were not able 

to survive. As the worldwide transport of merchandise on the oceans is steadily 

increasing, so, too, is the transport of macroalgae spores and juvenile stages in the 

ballast water. Two other vectors related to the arrival of alien species are aquaculture 

farming and unfortunately also the escape of material from scientific research. Known 

alien species from German coastal waters can form mono-specific stands in the 

invaded habitats, potentially with persistent impact on the native assemblage 

structure. 

The aim of this work was the publication of a complete check-list and synonym 

list for marine and brackish macroalgae for Germany including all invasive species 

encountered during the last century as a basis for further research. We disclaim in 

this publication any risk analysis for German macroalgae because this was already 

done by SCHORIES et al. (1995) and is under current revision by the German Federal 

Agency for Nature Conservation (Bundesamt für Naturschutz, BfN). 

1 Study Area and Methods 

North Germany is bordered on its Western side with the North Sea and on its 

Eastern side with the brackish Baltic Sea. This geographical feature results in a 

variety of water bodies, differing in macroalgae richness. Detailed description about 

different water typologies for the North and Baltic Sea are given by GOSSELCK et al. 

(2003). Due to the lack of distribution data for marine macrophytes we distinguish 

here only between (1) the Eastern Frisian Wadden Sea, (2) the Northern Frisian 

Wadden Sea, (3) the area around the Island of Helgoland, (4) the Western German 

Baltic Sea from Flensburg to the island of Fehmarn and (5) the Eastern German 

8

Baltic Sea between the island of Fehmarn and the German Polish border at the 

Island of Usedom. 

In this study we set the frontiers of the Northern Frisian Wadden Sea area as 

follows: (1) The area of the Schleswig-Holstein Wadden Sea National Park, 

comprising the western coast of Schleswig-Holstein and including the North Frisian 

Islands and (2) the Hamburg Wadden Sea National Park, extending from the mouth 

of the Elbe river to the the islands of Neuwerk and Scharhörn. The Western Frisian 

Wadden Sea comprises the Lower Saxony Wadden Sea National Park with the 

northern coast of Lower Saxony and including the East Frisian Islands. 

We revised all literature available between the years 1819 and 2008. In some 

cases direct access to the literature was not possible; here we used only the sources 

with given references. References for data records were not included in our literature, 

if they were mentioned already in one of the following check-lists (Nielsen et al. 1995, 

SCHORIES et al. 1995, SCHORIES et al. 1997, BARTSCH & KUHLENKAMP 2000). Further 

on we included also all information about data records of the herbarium material at 

the University of Kiel and records of the THEODOR REINBOLD collection of the 

State Botanical Collection, Munich. One of the oldest sources for the intertidal areas 

of the German Wadden Sea, is the excursion diary of PAUL KUCKUCK, written 

between 1891 and 1899. The original work was kept by the german algologist PAUL 

KORNMANN until his death. A copy of the diary is available by the authors. In 

accordance with the National Agency of Environment (Umweltbundesamt) and the 

State Agency for Agriculture, Environment and Rural Areas of Schleswig-Holstein 

(LLUR, formerly LANU) and in conformity with the upcoming Red list of threatened 

and potentially threatened Algae of Germany, we used for our taxonomic 

classification the online-resource http://www.algaebase.org (GUIRY & GUIRY 2009). 

2 Results & Discussion 

2.1 species distribution and richness 

The algae phyla Charophyta, Chlorophyta, Ochrophyta and Rhodophyta are 

present in German coastal waters. All together they present 469 species that have 

been recorded since 1819 including insecure registrations and single observations. 

(Tab. 1 & Appendix 1). Worldwide at least 3677 synonyms are known for these 

species. 

Highest total species richness is documented for Helgoland with 322 species, 

followed by the Western and Eastern Baltic Sea with 211 and 181 species, 

respectively. Both parts of the Frisian Wadden Sea sustain about 110 species with 

dominance of Chlorophyta species. In general species richness decreased from the 

marine rocky shore environment around the island of Helgoland to the brackish 

waters of the Baltic Sea with its limited stable substrates. 

The Charophyta make up the smallest group with only 2 orders and two 

families. 8 species have been registered along the coast, seven of them are only 

present in the eastern part of the Baltic Sea, six of them were found in the western 

part of the Baltic Sea. One species is known from Eastern Frisian Wadden Sea. The 

Chlorophyta are present with 9 orders, 23 families and a total of 130 species. More 

than 900 synonyms are known for this group. Species richness is highest around the 

9

island of Helgoland, from where a total of 86 species are known. The Northern and 

Eastern Frisian Wadden Sea present 47 and 52 species, respectively. Nearly the 

same species numbers are known from the Baltic Sea, where 52 species were 

identified in the Eastern and 54 species in its Western part. Species richness from 

the phylum Ochrophyta is higher than of Chlorophyta around the island of Helgoland 

and in the Baltic Sea; whereas it is lower in both parts of the Wadden Sea. Species 

number of members from the Rhodophyta is in the same order as that of of 

Ochrophyta. 160 species from 12 orders and 22 families are known. Again the waters 

around the island of Helgoland show highest species richness with a total of 103 

species, sustaining 32 species more than known from the Eastern Baltic Sea and 24 

species more than in the Western Baltic Sea. The presence of Rhodophyta is low in 

both parts of the German Frisian Wadden Sea and is consistent with the findings for 

species records from Ochrophyta.

2.2 Historical trends 

Helgoland 

A detailed species list and historical reflection of the macroalgae flora of 

Helgoland was published by BARTSCH & KUHLENKAMP (2000). They reported a total of 

274 species and additionally 51 doubtful records. The publication based on the 

analysis by HARMS (1993), KORNMANN & SAHLING (1977) and LÜNING (1970) and own 

studies, is the most complete work known from the German coast. Since then at least 

two new species are now known to exist in Helgoland,the red algae Halurus 

flosculosus and Neosiphonia harveyi (Bartsch & Kuhlenkamp 2009). 

BARTSCH & KUHLENKAMP (2000) clearly demonstrated changes of the algae 

flora both before and after the second world war: “Of the algae found after 1959, 68 

species belong to the Chlorophycota, 65 to the Phaeophycota and 81 to the 

Rhodophycota, whereas from 1860 to the 1930s about 40% fewer species of 

Chlorophycota were found (41 versus 68), a similar number of Rhodophycota 

species (81 versus 84), but 27% more species of Phaeophycota (89 versus 65), 

compared with the later period.” Due to immense research activities since the mid 

1840s the macroflora of Helgoland is today the best studied of German waters 

(BARTSCH & KUHLENKAMP 2000). The authors mainly identified the following reasons 

for the shift in species composition: (1) changes of substratum due to the building of 

protective moles, harbour constructions and breakwaters from the early 1920s 

onwards and (2) the variation of abiotic factors such as nutrients and temperature 

over the considered time period. However BARTSCH & KUHLENKAMP (2000) state also 

11

that exact ecophysiological knowledge of most rare or supposedly extinct species is 

missing and impede to draw specific conclusions. 

The Wadden Sea 

The knowledge about marine macroalgae of the German Wadden Sea and its 

presence on secondary hard substrates has never been in the focus of German 

algologists, although several authors have focused on the species composition of 

intertidal and subtidal benthic associations (NIENBURG 1927, LINKE 1939). Species 

richness and the availability of substrates are similar between the Northern and 

Eastern Frisian Wadden Sea. Observed differences are most probably related to the 

restricted research in the intertidal and subtidal mudflats and its existent hard 

substrata. Historical trends seem to be same between both areas and only differ in 

magnitude. This facilitates a joint historical overview: More than a hundred years ago, 

the first curator of botany at the Marine Station on Helgoland (Biologische Anstalt 

Helgoland) PAUL KUCKUCK (1866–1918), carried out some excursions to the 

Wadden Sea and noted his records in a field diary. These records give us the first 

insights about the presence of macroalgae species on intertidal mudflats in the 

former century. Twenty years before KUCKUCK, EIBEN (1871) had already studied 

the macroalgae associations on artificial structures like dikes and buoys. 

During the subsequent decades various authors studied macroalgae locally, 

for example in the vicinities of the Königshafen of the island Sylt (NIENBURG 1927, 

KORNMANN 1952, LUTHER 1976, SCHORIES et al 1997) or in the Weser estuary (LINKE 

1939, BEHRE 1961, MICHAELIS 1969, KOEMAN 1975). During the 1980s KOEMAN & VAN 

DEN HOEK (1982a, b, 1984) studied the taxonomy of the genus Enteromorpha in the 

Netherlands but samples were also taken from Germany. At the end of the 1980s 

green algae mats covered wide areas of the East & North Frisian Wadden Sea 

(REISE & SIEBERT 1994, SCHANZ & REISE 2005, REISE et al. 2008). Single mats 

covered up to 9 km 2 in the East Frisian Wadden Sea. Early information about 

macroalgae in the subtidal channels and deeper waters were often provided due to 

the harvest of mussels and oysters (HAGMEIER & KÄNDLER 1927, HAGMEIER 1941), 

however natural banks had already declined significantly by the 1850s (MOEBUIS 

1877, GESSNER 1957). Riffs built by the polychaete Sabellaria spinulosa might have 

been important substrates for algae growth but today nearly all riffs have 

disappeared (EIBEN 1871, VORBERG 2005). Due to this phenomenon green algae 

distribution and identification has been studied in more detail (KOLBE et al. 1995, 

SCHORIES 1995). Nevertheless our knowledge about macroalgae distribution in the 

Wadden Sea remains a patchwork. Additions to the actual check list are almost 

certain if future investigations concentrate on the low subtidal channels and 

secondary hard substrata (VLAS et al. 2005). 

Baltic Sea 

First algae collections for the German coastal waters of the Baltic Sea go back 

to the year 1819 (LYNGBYE 1819). At the end of the 19th Century REINKE (1889) 

summarized the previous activities of material collected since 1819. He noted 

critically that many species had been incorrectly identified and were subsequently 

corrected by him. His work on the algal flora of the western Baltic Sea built together 

12

with the publications of REINBOLD (1889, 1890) the basis (REINKE 1889) for our recent 

knowledge. During the second part of the last century SCHWENKE (1964, 1965, 1966, 

1969) started an extensive video-transect in the Kiel Bay, but none of the material is 

still available today. However, the main results of the working group of SCHWENKE 

(1964, 1965, 1966, 1969) is reflected in the distributional index of the benthic 

macroalgae of the Baltic Sea area (NIELSEN et al. 1995) and the Red List & Flora List 

of marine macroalgae of Germany (SCHORIES et al. 1995). These lists include several 

small macroalgae species never revised thereafter. 

Following the decreasing salinity gradient from West to East, with a marked 

decline east of the Darßer threshold, several macroalgae species are limited in their 

distribution due to low salinities. However, we followed in our check-list the former 

area definitions used by SCHORIES et al. (1995) to separate species records from the 

state of Schleswig-Holstein and Mecklenburg-Western Pomerania. This partly 

explains why the decrease in species richness is not as high as it would be if the 

Darßer threshold would have been taken as the borderline. The best historical 

information for Eastern Germany is provided again by REINKE (1897, 1899, 1901) and 

REINKE & DARBISHIRE (1898) followed by LAKOWITZ (1887, 1907, 1929). More recently 

OVERBECK (1964), PANKOW (1971), MARTENS & PANKOW (1972) & PANKOW et al. 

(1990) revised the macroalgae flora of the former German Democratic Republic. 

Since 1997 macroalgae distribution along the German Baltic coast were investigated 

in the monitoring program State Agency for Environment, Nature and Geology 

Mecklenburg-Western Pomerania and from the State Agency for Agriculture, 

Environment and Rural Areas Schleswig-Holstein (FÜRHAUPTER et al. 2004-2007). 

In addition to the poor historical and recent data for the elaboration of an 

accurate species list, data for depth distribution for single species or communities in 

the Baltic Sea is also lacking or is doubtful. Former algologists often dredged the 

material from the bottom and included free floating algae in its depth records. After 

KOLDERUP-ROSENVINGE (cited in VÄLIKANGAS 1933) the greatest depth distribution of 

algae is about 38m, REINKE (1889) assumed a depth limit of 30m, whereas LAKOWITZ 

(1929) reports of 25m as maximum depth for red algae and BREUER (1989) gives the 

limit for the vegetation at approximately 22m depth. We consider 23m as the lowest 

limit for trustworthy historical depth records (SCHORIES et al. 2006). 

It was BREUER (1989) who provided an excellent overview about the depth 

distribution of all common macroalgae of Kiel bay. More recently SCHORIES et al. 

(2006) and FÜHRHAUPTER et al. (2005-2007) focused on the distribution of the 

common macroalgae along the whole German Baltic coast, but never went into such 

detail as the working group of SCHWENKE did between 1957 and 1992 during the last 

century. A general overview about the macroalgae of the Baltic Sea is given by 

SCHUBERT & SCHORIES (2008). Apart from these reports and publications further work 

has been carried out considering only a single species up to a few species (f. e. 

DARBISHIRE 1896, HOFFMANN 1952, KAMINSKI 1980, SCHUELLER & PETERS 1994, 

SCHORIES et al. 2006). However the general problem is that up until about 20 years 

ago, a complete revision of the present state of the German macroalgae in the Baltic 

Sea had never been undertaken. 

2.3 Temporary guests and neophytes 

In the full marine environment the number of registered neophytes is constantly 

increasing. Neophytes do not always permanently establish themselves in an area, 

although they might be present for a couple of years. The island of Helgoland is 

13

isolated in the North Sea and dispersal and arrival of common North Atlantic species 

is restricted. Therefore KORNMANN & SAHLING (1977) considered species like 

Himanthalia elongata as temporary guests. These species may be present for a while 

then disappear again. For example H. elongata was found on Helgoland from 1959 – 

1962, but was not seen again in subsequent years. 

The presence of neophytes increased during the last decades, but total the 

number does not exceed 11 species (Tab. 2). In a paper ranking specific traits of 113 

macroalgae introduced into Europe for the three main categories: dispersal, 

establishment and ecological impact; Sargassum muticum overall was the eighth 

most invasive species (NYBERG & WALLENTINUS in press). FLETCHER & FARELL (1999 

and references therein) discussed the role they could have played in being a vector 

for the introduction to the North Atlantic of some epiphytic macroalgae and 

invertebrates. S. muticum is established around the island of Helgoland (BARTSCH & 

KUHLENKAMP 2000). Callithamnion tetragonum, Halurus flosculosus and Neosiphonia 

harveyi are the most recent neophytes from Helgoland (Kuhlenkamp pers. com. 

2008; Bartsch & Kuhlenkamp 2009).

In Königshafen Bay (island of Sylt – North Frisian Wadden Sea) S. muticum 

was first recorded attached to a substratum in 1993 (SCHORIES & ALBRECHT 1995, 

SCHORIES et al. 1997), but drift material was also reported before from the East 

Frisian Wadden Sea (KREMER et al. 1983). It grows in the Wadden Sea on 

musselbeds and on secondary hard substrates. It is well established in sheltered 

areas of the island of Helgoland where it grows among other fucoids and in intertidal 

basins. From 2002 onwards the red alga Gracilaria vermiculophylla spread out in the 

German Wadden Sea (NEHLS 2006, BUSCHBAUM et a. 2008). Presently it is found in 

the North and East Frisian Wadden Sea forming locally dense mats on intertidal 

mussel beds and mudflats. 

In the Baltic Sea Gracilaria vermiculophylla, was found first in 2006 in the Kiel fjord 

as drifting material (SCHORIES & SELIG 2006). WEINBERGER et al. (2008) observed the 

14

expansion of G. vermiculophylla, in the Kieler Bight during the last three years. The 

Eastern most expansion is actually near the island of Fehmarn. However it is known 

G. vermiculophylla can sustain growth between 2-40 psu, 5-30°C, low and high light 

levels (YOKOYA et al. 1999, RAIKAR et al. 2001, RUENESS 2005, NYBERG 2006, 

WEINBERGER et al. 2008) and a spread in the Eastern Baltic Sea is probable. Two 

other neophytes were found during the last two decades in the Western Baltic Sea, 

the red alga Dasya baillouviana and the brown alga Fucus evanescens (SCHUELLER & 

PETERS 1994, NIELSEN & MATHIESEN 2005). Codium fragile and Bonnemaisonia 

hamifera where already present before. Dasya baillouviana is increasingly common 

in a depth between 3-6m.
