Floristic Element

This paper deals with the forest plant community of beech, fir and spruce (Piceo-Fago-Abietetum Colic 1965), which is the most widely distributed plant community on the territory of national park ?Tara?. Spectrum of life forms and floristic elements are specified for this community. Spectrum of life forms shows that hemicryptophytes are the most frequent, with high occurrence of geophytes, which is characteristic of this mesophilous plant community. Spectrum of floristic elements show that centraleuropean floristic element is dominant and that this plant community is under strong influence of subcentraleuropean region. Five subassociations are set apart on the basis of floristic composition and site conditions: typicum, drymetosum, aceretosum, pinetosum silvestrae and vaccinietosum. Spectrum of life forms is made for every subassociation separately in aim to compare their floristic compositions. Subassociations aceretosum and vaccinietosum are characterized by the highest occurence of phanerophytes, and the lowest occurence of this life form is represented in subassociation drymetosum. The highest occurence of geophytes is in subassociation aceretosum, and the lowest in pinetosum silvestrae and vaccinietosum. Occurence of hemicryptophytes is the highest in subassociations drymetosum and pinetosum silvestrae, and the lowest in aceretosum. Subassociation typicum is stable plant community, subassociations drymetosum and vaccinietosum grow on poorer sites, while subassociations aceretosum and pinetosum silvestrae represent degradation of beech, fir and spruce forest (Piceo-Fago-Abietetum Colic 1965).

Aswan Reservoir

The present study was undertaken to survey the floristic composition in the islands and shorelines in Aswan Reservoir, south of the River Nile at Aswan Governorate, Egypt. Four elements of vegetation were analyzed: floristic composition, lifespan, life form, and phytogeographical affinities. A total of 165 species were recorded belonging to 134 genera in 45 families of vascular plants, of which six species were new to the flora of Aswan and Nubia (Amaranthus spinosus, Doellia bovei, Eleocharis parvula, Haematoxylum campechianum, Polygonum aviculare, and Pithecellobium dulce). The most represented families are Leguminosae, Poaceae, and Compositae. Species richness is highest in low-lying areas (shorelines) liable to flooding, compared to those of the islands in the river. The recorded flora consists of 50.91% perennials and 49.09% annuals. Therophytes and phanerophytes were the predominant life forms. Phytogeographical analysis revealed the prevalence of the pantropical (28.48%), palaeotropical (17.57%), and cosmopolitan (16.36%) plant species. Monoregional chorotype was represented by 29 species (17.58%) of the recorded flora with the Sudano-Zambezian species (11.52%) being the highest chorotype, while pure Mediterranean species were very poorly represented (3.63%). Biregional chorotype was represented by 25 species (15.15%), while the pluriregional chorotype was accounted for 2.43% of recorded species.

A floristic diversity and vegetation forest structure was carried out on the Mount Payung, Ujung Kulon National Park. The objective was to floristic composition and structure of the forest located at the peninsula of Ujung Kulon, Banten. The study was conducted using the quadrat method by establishing plots of 5000 m2 each at two locations Pasir Ipis and Gunung Keneng, thus the total area sampled was 1 ha. They were Plot Pasir Ipis and Plot Gunung Keneng. A total of 1898 trees comprising 105 species of 74 genera and 43 families were recorded. The number of species at Pasir Ipis higher (90 species) than plot Gn Keneng (61 species). Based on calculation the important value indexes (IVI), there were some dominan species with IVI >10 at Pasir Ipis Neesia altissima (IV=21,55), Barringtonia racemosa (17,89), Payena acuminata (13,35) and Neonauclea lanceolata (12,37). The dominated species at Plot Gn Kendeng were Pseuduvaria reticulata (IV= 34,30), Dillenia excelsa (27,62), Lagerstroemia speciosa (20,89), Popowia pisocarpa (17,57). The structure of forest could be inferred from the diameter and height of trees. The diameter measurements showed that 75,57 % of trees in plot Pasir Ipis and 80,51 % in plot Gunung Kendeng consist of small individuals with diameters between 10-20 cm. Trees with large diameters of >100 cm occurred in two plots among them Barringtonia racemosa, Polyalthia lateriflora, Popowia pisocarpa, Artocarpus elasticus. The presence of large numbers of small trees and lesser numbers of trees with large diameters in a forest stand indicated that the stand was regenerating after heavy disturbance. The presence of the majority of trees with height of < 20 m (99 %) further confirmed the forest’s dynamic status.

Field surveys were carried out to evaluate the floristic diversity and biological spectrum of Lower Tanawal, District Abbottabad in different seasons during 2016-2018. This study area was divided into 80 stands on the basis of physiognomy of the vegetation. Life form classes and leaf spectra were classified following Raunkiers methodology. In total, 286 plant species belonging to 86 families were recorded, out of which herbaceous growth form dominated the study area with 187 species, followed by shrub with 54 species. Among all 86 families, Asteraceae was found to be the most dominant family with 25 species, followed by Fabaceae with 24 species and Rosaceae with 20 species. Based on life form classes, Therophytic life form was the leading class with 113 species (39.5104%), followed by Nanophanerophytes with 45 species (15.7342%). In leaf size spectra, Microphylls dominated the flora with 88 species (30.7692%), followed by Mesophyll with 81 species (28.3216%). This study shows the complete floristic composition that may be important as reference work for future ethnobotanical, ecological and conservational studies.

The paper describes the floristic diversity and specifies its use value in terms of feeding preferences of konik polski horses and their consumption of permanent grassland in a section of the Wieprz river valley in Roztocze National Park. The flora assessment was conducted by analyzing 79 phytosociological relevés using the Braun-Blanquet method. The results of phytosociological surveys made it possible to distinguish 7 complexes in the Phragmitetea class, 5 complexes and 1 plant community in the Molinio-Arrhenatheretea class, and 1 complex in the Nardo-Callunetea class. Natural values of the examined associations were described based on the total and average number of species in a phytosociological relevé, the Shannon-Wiener index, and the phytosociological structure of plant communities. The use value of dry weight of the analyzed meadows and pastures was estimated by means of the use value number (UVN) and taking into account the and yield size. The phytocoenoses identified in the meadows in the section of the Wieprz river valley under study exhibited high natural values (H’ = 3.20–4.62). The dry weight yields of the examined communities varied (from 1.32 to 5.37 t ha–1), but their sward usually had poor and very poor use value (UVN = from –0.55 to 5.8). Furthermore, it should be noted that the sward of wet meadows is readily consumed by the grazing animals, which contributes to the improvement of the natural and use value of meadows.

A qualitative floristic exploration with life form classifications and monitoring of flowering and fruiting phenology has been carried out at a restored site near Puducherry, South India in 2009 and 2010. The species were classified into three categories based on their occurrence status, namely, Naturally Occurring, Naturally Regenerated and Introduced. The present study focuses only on two life forms, the Herbaceous and the Climbing plants. The site selected for eco-restoration originally comprised of an eroded and severely degraded landscape with scattered remnant species. However, active human intervention over a thirty year period included the introduction of appropriate plant species and other physical measures to enhance soil fertility and ground water level, and regenerate and conserve the deteriorating typical Tropical dry evergreen forest (TDEF) vegetation. A large number of naturally ccurring herbaceous, climbing species (172) and a consistent number of naturally regenerated species (44) are now observed as a result of eco-restoration. Lowland herbaceous species have also established themselves as a green cover at ground level. At present, parts of the area have fertile soils and rich floristic composition with the herbaceous life form represented by 165 species encompassed in 105 genera and 37 families, and the climbing plants represented by 68 species belonging to 54 genera and 25 families. ‘Genus to family’ and ‘species to genus’ ratios indicate the establishment of diverse vegetation in the study site. Nearly one third of the species have been observed flowering throughout the year and about half of the species were observed fruiting throughout the year. We emphasize that the two fold approach of land and vegetation reclamation has been very effective in helping restore the unique TDEF vegetation at the local level and the same may be extended to help regenerate and conserve the Coromandel Coastal vegetation at the regional scale.

O objetivo da pesquisa foi conhecer a composição florística da regeneração natural de um trecho de savana amazônica no estado do Pará. O estudo foi realizado em uma savana na localidade de Itapuá, município de Vigia de Nazaré, Pará a 93 km da cidade de Belém. A coleta de dados ocorreu mensalmente no período de setembro de 2019 a fevereiro de 2020 em 80 subparcelas de 1 x 1m alocadas aleatoriamente correspondente a 480 subparcelas em um total de 480 m2. Em cada subparcela foram identificadas e quantificadas todas as espécies com altura ≤ 1 m. A identificação botânica in loco foi realizada por um parabotânico do Museu Paraense Emilio Goeldi (MPEG. A organização das famílias foi de acordo com APG IV e caracterizada em família, gênero, espécie e forma de vida e calculada a média aritmética e desvio padrão com auxílio do Programa Bioestat 5.0. Foram registradas 36 famílias, 73 gêneros e 99 espécies. Fabaceae (14), Poaceae (13), Cyperaceae (9), Myrtaceae (7) e Dilleniaceae (6) foram representativas em número de espécies. Paspalum registrou o maior número de espécies (5) seguido por Chamaecrista, Myrcia  e Scleria (4) e Axonopus, Borreria, Byrsonima, Davilla, Doliocarpus, Eriosema, Eugenia, Miconia, Ouratea, Polygala e Rhynchospora (2). A forma de vida dominante foi de Erva com 40 espécies, Arbusto (21) e Árvore (20). A savana de Itapuá apresentou riqueza de 99 espécies, 36 famílias e 73 gêneros estando acima que outras savanas amazônicas cujas espécies estiveram distribuídas nas famílias Fabaceae, Poaceae e Cyperaceae. O gênero Paspalum com o maior número de espécies juntamente com outras caracterizou a forma herbácea como a dominante. Este foi o primeiro registro de espécies regenerantes e suas formas de vida em uma savana amazônica. Com base nesses conhecimentos, outras iniciativas devem ser buscadas para outras manchas de savanas visando mostrar a importância da conservação destes ambientes que ultimamente vem sofrendo ampla degradação na Amazônia.  Floristic composition of the regeneration of a stretch of savanna in the Eastern Amazon A B S T R A C TThe savannas are Amazonian and represent an ecological potential for use in several aspects, especially for traditional communities, however, they are suffering forest, environmental and human losses.The objective of the research was to know the floristic composition of the natural regeneration of a stretch of Amazonian savanna in the state of Pará. The study was carried out in the savanna of Itapuá, municipality of Vigia de Nazaré, Pará wich 93 km from the city of Belém. Data collection occurred monthly from September 2019 to February 2020 in 80 1 x 1m subplots randomly allocated corresponding to 480 subplots and a total of 480 m2. In each subplot, all species with height ≤ 1 m were identified and quantified. The botanical identification in loco was carried out by a parabotan from the Museu Paraense Emilio Goeldi (MPEG. The organization of the families was in accordance with APG IV and characterized in family, genera, species and way of life and calculated the arithmetic mean and standard deviation for families and life forms with the aid of the Bioestat 5.0 Program, 36 families, 73 genera and 99 species were registered, Fabaceae (14), Poaceae (13), Cyperaceae (9), Myrtaceae (7) and Dilleniaceae (6) were representative in number of Paspalum registered the largest number of species (5) followed by Chamaecrista, Myrcia and Scleria (4) and Axonopus, Borreria, Byrsonima, Davilla, Doliocarpus, Eriosema, Eugenia, Miconia, Ouratea, Polygala and Rhynchospora (2). Dominant life form was Herb with 40 species, Shrub (21) and Tree (20). It was concluded that the Itapuá savanna presented a richness of 99 species in comparison to other Amazonian savannas distributed in the Fabaceae, Poaceae and Cyperaceae families. Paspa lum with the largest number of species together with others characterized the herbaceous form as the dominant one. This was the first record of regenerating species and their life forms in an Amazonian savanna. Based on this knowledge, other initiatives should be sought for other savanna patches in order to show the importance of conserving these environments, which lately has been undergoing extensive degradation in the Amazon.Keywords: Lower stratum; way of life; conservation.

Biodiversity Analysis

Terra Nova National Park, located on the east coast of Newfoundland, has a vascular flora of 535 taxa, including 33 rare species and 94 introduced taxa. About 75% of the native flora of the Park is composed of hemicryptophyte and cryptophyte species. Phanerophytes and nanophanerophytes represent only 13% of the flora, but the percentages of occurrence of these life forms reaches 31%. The flora of the Park is mainly boreal (56%), composed mainly of Boreal North American, Boreal Eastern North American, and Circumboreal elements. Arctic-alpine species are infrequent. We report two species as new to Newfoundland: Festuca richardsonii Hooker (Poaceae) and Carex communis L.H. Bailey var. communis (Cyperaceae). Significant positive and negative associations between (i) life forms and (ii) phytogeographical elements, and the distribution of species within the habitats of the Park were established using the Fourth Corner Method. Distribution of life forms and phytogeographical elements within habitats of the Park appears to be explained more by ecological characteristics of species than by their history.Key words: life form, biogeography, biodiversity, Terra Nova National Park, Newfoundland, Canada.

Floristic Characteristics

The association of beech and fir was researched on Mt. Suvobor, on serpentinite bedrock. In the past, the beech and fir forest on Suvobor was not studied, it was just referred to, so the objective of this paper was to study the floristic characteristics of this forest, which will enable its ecological-vegetational differentiation and widen the knowledge on beech and fir associations on serpentinites. The studied plant community is characterised by poor floristic composition and by the absolute domination of fir in the tree layer. In the life form spectrum, the dominant plants are phanerophytes, and the percentage of geophytes is increased, which points out the mesophilous plant community. The spectrum of floral elements indicates the dominance of the Central-European floral element, but also a significant percentage of some more xerophilous elements, which is the consequence of a specific parent rock.
