Resumo: | The present work examined the floristic compositions and structures, and the similarities between seven areas degraded by mechanized diamond mining along the São José River Valley (12o34’ to 12º36’ S - 41o22’ to 41º35’ W), in the municipality of Lençóis, Bahia State, Brazil, after 23 years of abandonment and natural regeneration and compared them to an area of intact gallery forest along the same river. The collections were made between the months of April and December/2011 along 1 x 100 m transects established in each of the seven areas, applying the point method. A previously compiled species list was used to compare the seven recovering areas with an intact riverine forest site. A total of 62 species were encountered, distributed among 53 genera and 26 families. The families demonstrating the greatest species richness were Leguminosae (16), Poaceae (11), Cyperaceae (7), Melastomataceae (6), Malvaceae (4), and Lycopodiaceae (2). The sum of the richnesses of these families represented fully 74% of the total number of species recorded in the present study. In terms of the plant habits, 11 species (15%) were arboreal, 17 (26%) shrubs, 28 (42%) herbaceous, 07(11%) sub-shrubs, and 04 (6%) vines. The species demonstrating the greatest Relative Vigor and Cover were Sebastiania corniculata, Aristida setifolia, and Homolepis aturensis. The slow natural regeneration of these areas was apparently due to the modification of the soil structure by the mechanized mining, as judged by the greater similarity (although low) between the areas regenerating for the longest periods and the intact gallery forest site along the same river as performing solo one little more structured.c |

As coletas foram realizadas entre abril a dezembro de 2011 ao longo de um transecto de 1m x 100m em cada uma das áreas onde foi aplicado o método de pontos em cada uma das áreas. Para comparar com o remanescente florestal do entorno, foi usada a lista de espécies da floresta ciliar elaborada previamente. Foram amostradas 62 espécies distribuídas em 53 gêneros e 26 famílias. As famílias com maior riqueza de espécies são Leguminosae (16), Poaceae (11), Cyperaceae (7), Melastomataceae (6), Malvaceae (4), Lycopodiaceae (2). O somatório da riqueza destas famílias representa 74% do total das espécies levantadas neste estudo. Em termos de hábito foram encontradas 11 (15%) espécies arbóreas, 17 (26%) espécies arbustivas, 28 (42%) herbáceas, 07(11%) subarbustivas e 04 (6%) trepadeiras. As espécies que mais se destacaram por Vigor Relativo e Cobertura foram Sebastiania corniculata, Aristida setifolia e Homolepis aturensis. A lenta regeneração natural das áreas se deve às más condição do solo que apresenta-se modificado pelas ações do garimpo, tendo sido evidenciada uma maior similaridade, embora baixa, entre as áreas de maior tempo de abandono que apresentam solo um pouca mais estruturado e o remanescente florestal ciliar do rio São José.Submitted by Verena Bastos (verena@uefs.br) on 2015-09-16T22:20:18Z No. of bitstreams: 1 Dissertação finalpdf.pdf: 1860889 bytes, checksum: ee87b81fe0a21430df0bad836a2fe39f (MD5)Made available in DSpace on 2015-09-16T22:20:18Z (GMT).

description |
The present work examined the floristic compositions and structures, and the similarities between seven areas degraded by mechanized diamond mining along the São José River Valley (12o34’ to 12º36’ S - 41o22’ to 41º35’ W), in the municipality of Lençóis, Bahia State, Brazil, after 23 years of abandonment and natural regeneration and compared them to an area of intact gallery forest along the same river. The collections were made between the months of April and December/2011 along 1 x 100 m transects established in each of the seven areas, applying the point method. A previously compiled species list was used to compare the seven recovering areas with an intact riverine forest site. A total of 62 species were encountered, distributed among 53 genera and 26 families. The families demonstrating the greatest species richness were Leguminosae (16), Poaceae (11), Cyperaceae (7), Melastomataceae (6), Malvaceae (4), and Lycopodiaceae (2). The sum of the richnesses of these families represented fully 74% of the total number of species recorded in the present study. In terms of the plant habits, 11 species (15%) were arboreal, 17 (26%) shrubs, 28 (42%) herbaceous, 07(11%) sub-shrubs, and 04 (6%) vines. The species demonstrating the greatest Relative Vigor and Cover were Sebastiania corniculata, Aristida setifolia, and Homolepis aturensis. The slow natural regeneration of these areas was apparently due to the modification of the soil structure by the mechanized mining, as judged by the greater similarity (although low) between the areas regenerating for the longest periods and the intact gallery forest site along the same river as performing solo one little more structured.c |
