“…Also, with the prohibition of wood removal, the amount of dead wood increased. Coarse wood debris in various stages of decay is now plentiful on Moricsala Island (Madžule & Brūmelis, 2008;Brūmelis et al, 2011), which has provided an abundant and diverse substrate for bryophyte colonization (Sö derströ m, 1988;Humphrey et al, 2002). Kupffer described Nowellia curvifolia, a species that occurs on well decayed logs, as very rare, while today the species is very common in most forest types on the island.…”

AS 'Latvijas valsts meži', Riga, LatviaBryophyte species composition, richness and life-form distributions were studied in a succession after termination of land-use as meadows and pasture in the Moricsala Strict Nature Reserve. Detailed lists of bryophyte species in various vegetation types, which were produced in the early 1900s by Karl Reinhold Kupffer, were compared with those prepared from 2006 to 2010 to determine changes in species composition. Colonisations and extinctions of bryophyte species and life forms could be explained by increases in available substrates (living trees, dead wood, ground layer disturbance patches), and increasingly shaded conditions. In each forest type, the species diversity (alpha diversity) increased, but the differences (beta diversity) between the types decreased. The total number of bryophyte species recorded in the studied forest area increased from 110 to 134 and that of rare (including Woodland Key Habitat indicator species) and protected species from 14 to 21 species. Twenty species were lost during the forest succession, but most of these species still occur within the reserve in open habitats. Life forms such as small compact cushions and short turfs tended to be lost during the forest succession, while smooth and rough mat life forms were better adapted to the new conditions and increased in richness.

“…On the other hand, time gaps in cohort structure can result from poor light availability caused by competition (Harmer et al, 2001;Küßner, 2003). Shading might also explain the succession to relatively more shade tolerant species, such as P. abies (Kinguru and Rauda), F. excelsior (Audile, Pededze, and Barkava), and T. cordata (Salenieki), as reported previously for the Moricsala Reserve in Latvia (Brūmelis et al, 2011a). Succession of mixed Q. robur stands to species-rich spruce-deciduous forest has occurred also on Abruka Island in West Estonia (Meikar et al, 2004).…”

In seven Quercus robur stands in Latvia, the past history of stand development was determined by size and age structure of trees, dead wood amounts, cut stumps, and by forest inventory records and maps. All the stands met the criteria of Woodland Key Habitats. Quercus robur was the main canopy species in all stands. Since the time of the recruitment of canopy trees, there has been minimal release of the Q. robur in the > 1-m height class, at least among those that have survived until today. One stand lacked evidence of natural successional processes, while the others were naturally regenerating with Picea abies or deciduous tree species, such as Fraxinus excelsior, Ulmus glabra, Alnus glutinosa, and Tilia cordata. The dead wood amounts in plots suggest a high level of naturalness. However, the ages of the canopy oaks (up to 226 years) indicate lack of long-term natural development. Also, the presence of cut stumps in three plots and lack of standing dead wood in four plots are signs of the impact of human disturbance on natural processes. Since the 1920s, one of the stands had converted from a Populus tremula and Betula pendula to a Q. robur canopy. Even though the studied stands can be considered as having low naturalness based on age structure and past management history, they each supported two to eight Woodland Key Habitat indicator species, including one to six protected species.

“…Tilia cordata was common in the broad-leaved tree stand groups in all tree layers, and in one group was the dominant tree species. Succession of tree species to increased proportion of T. cordata has been previously described in the boreo-nemoral forest zone (Brumelis et al 2011) and as a tolerant species can be the dominant species on richer soils (Pigott 1991). The leaf litter of T. cordata is basic, which promotes cycling of elements (van Oijen et al 2005) and a nemoral flora and associated epiphyte community is typical of these stands (Mezaka et al 2012;Auniņš 2013).…”

“…In appropriate soils, natural Q. robur regeneration is common in P. sylvestris stands (Dobrowolska 2006;Goris et al 2007). It is well known, that Q. robur is replaced by shade tolerant species, like T. cordata (Brumelis et al 2011;Ikauniece et al 2012).…”

Tree regeneration in noble broadleaved tree stands at their northern limit: implications for conservation management

In Latvia, the noble broad-leaved tree species woodland with pedunculate oak (Quercus robur L.), small-leaved lime (Tilia cordata Mill.), Norway maple (Acer platanoides L.), wych elm (Ulmus glabra Huds.), white elm (Ulmus laevis Pall.) and common ash (Fraxinus excelsior L.) has decreased to about 1% due to the historical legacy of wood extraction and conversion of fertile soil to agricultural land-use. The aim of the current study was to determine the tree age structure in the canopy and size structure in the shrub layer of broad-leaved tree stands to determine past changes and to predict future trends in tree species composition in the context of potential management methods. In 50 randomly selected broad-leaved tree stands, plots of size 0.1 ha were established. In the plots, diameter at breast height was measured for all trees with diameter >10 cm and cores were removed from all of these trees. All other stems were counted by species in height classes ≤ 1 m, 1.1 to 5 m, 5 to 10 m. The stands were classified into 10 groups based on canopy composition in age classes. Norway spruce [Picea abies (L.) H. Karst.] was common in various tree layers of in many of the groups, and it is recommended that it should be removed during stand tending. Q. robur regeneration should be promoted in specific cases where abundant in the < 1 m layer and where large gaps can be created. T. cordata is commonly present in several tree layers and its growth could be promoted by thinning of P. abies where present. Abundant Q. robur regeneration is sometimes found in Scots pine (Pinus sylvestris L.) stands.
