The floristic composition and structural diversity were studied in two plots, 25 m x 25 m each, in three different sites of varying vegetation physiognomy: Taungya system, Regrowth forest and Gmelina arborea plantation (TS, RF and GA respectively) of Shasha forest reserve in Ile-Ife southwestern Nigeria. A total of 119 plant species belonging to 51 families and 100 genera were identified in the forest reserve. Woody species represented the most diverse life form. Plant species diversity was higher in the GA (H'=3.5) compared to the RF (H'=3.4) and TS (H'=2.9). Woody plant species density also differed significantly (p < 0.05) among the different physiognomy. Mean basal area and mean girth size were higher in RF compared to TS and GA. Species evenness was also quantitatively higher in the TS (E=0.12) compared to RF (E=0.09) and GA (E=0.08). Sorensen index of similarity were 12.12% (TS and RF), 19.71% (TS and GA) and 20.20% (RF and GA), which is an indication of the heterogeneity of the three different sites, as a result of different management systems of the sites. The knowledge about species composition in the forest reserve will go a long way in identifying important elements of plant diversity, protecting and preserving threatened plant species, monitoring and providing effective management of the forest reserve.

“…3 and 4). Keenan et al [18] showed that the percentage of woody species with seeds dispersed by mammals and birds increased with age in a Pinus caribaea plantation in Australia. The tall-tree species in the long-rotation plantations included trees with animal-dispersed seeds (F. japonica, Q. serrata, Kalopanax pictus, and Cornus controversa).…”

“…Some species with bird-dispersed seeds (e.g., Prunus maximowiczii and Cornus controversa) attain reproductive age in long-rotation but not in standard-rotation plantations (Nagaike & Hayashi, unpublished data). Keenan et al [18] pointed out that as plantations age, tree species that bear fruit that is attractive to frugivores have a chance to reproduce and, in turn, attract frugivorous birds [1,49]. Wunderle [49] demonstrated the importance of traits relevant to attaining seed dispersers, including perch availability, structural complexity of vegetation, and the presence of food resources, especially fruit, as an attractant.…”

-We compared the plant species diversity of forest-floor vegetation in long-rotation Larix kaempferi plantations with standardrotation plantations and abandoned coppice forest in central Japan. Species diversity and richness did not differ between the standard-and longrotation plantations. However, the composition of tall-tree species, of different seed-dispersal types, in long-rotation plantations differed from that in standard-rotation plantations, but was similar to that in abandoned coppice forest. These results indicate that, in particular, long-rotation plantations contained more tall-tree species with animal-dispersed seeds, which in turn suggests that long-rotation plantations may be better for colonization of tall-tree species with this type of seed dispersal. The relatively long period since management in long-rotation plantations may play a significant role in the growth, reproduction, and seedfall of naturally regenerated tall-tree species with animal-dispersed seeds. Therefore, long-rotation plantations may maintain and restore species composition via recovering ecological function.forest ecosystem management / seed dispersal / species classification / life form Résumé -Effets de l'allongement de la période de rotation des plantations de Larix kaempferi au centre du Japon sur la diversité en espèces végétales. Nous avons comparé la diversité en espèces végétales du sous bois entre des plantations de Larix kaempferi menées en rotations longues par rapport à des rotations classiques courtes ou des taillis abandonnés. La diversité et la richesse en espèces végétales ne diffèrent pas entre les plantations classiques et les plantations à longue rotation. Cependant, la diversité de la strate arborée, avec des stratégies de dispersion des graines différentes, diffère entre les plantations à longue durée par rapport aux plantations classiques mais est semblable aux taillis abandonnés. Les résultats indiquent en particulier que les plantations avec de longues rotations contiennent plus d'espèces arborées avec une stratégie de dissémination des graines par zoochorie ce qui suggère également que ce type de plantation longue soit favorable aux arbres avec ce type de dissémination. La longue période après la dernière intervention en forêt dans les plantations à longue rotation semble donc jouer un rôle important dans la croissance, la reproduction et la dispersion des graines par zoochorie pour les arbres se régénérant naturellement. Par conséquent, les plantations à longue rotation pourraient maintenir et restaurer la composition en espèces végétales par rétablissement de la fonction écologique. gestion des écosystèmes forestiers / stratégie de dispersion des graines / classification des espèces / type biologique

“…Adicionalmente, numerosos estudos nos últimos 20 anos têm demonstrado que plantações florestais com uma única espécie, mesmo aquelas destinadas primariamente à produção, dependendo da forma como são manejadas, podem acelerar a regeneração natural da vegetação nativa, funcionando como "catalisadoras" do processo de restauração florestal (amplas revisões sobre o assunto em Brockerhoff (2008) e Vianni et al (2010)). Com o tempo, os sistemas monoespecíficos plantados passam a ser enriquecidos por um número crescente de espécies advindas de fontes externas (LUGO, 1997;KEENAN et al, 1997;LAMB, 1998).…”

Normas jurídicas para a restauração ecológica: uma barreira a mais a dificultar o êxito das iniciativas?

RESUMO -A iniciativa de legislar sobre técnicas de restauração é recente no Brasil e, de acordo com as informações disponíveis, inédita no mundo, havendo controvérsias sobre a conveniência dessa legislação. Na tentativa de trazer luz ao debate, desenvolveu-se análise crítica da Resolução da Secretaria do Meio Ambiente do Estado de São Paulo, que normatiza o reflorestamento heterogêneo de áreas degradadas. Considerou-se que a norma se baseia em pressupostos que não encontram respaldo em experimentação científica, uma vez que o entendimento dos processos ecológicos envolvidos na restauração está longe de ser suficientemente completo para permitir legislar, com segurança e detalhamento, sobre o assunto. Adicionalmente, considerouse que nem os profissionais que elaboram projetos nem os que atuam no licenciamento e fiscalização detêm o conhecimento necessário para aplicar a norma. Entende-se ainda que o rigor das normas cerceia a criatividade e a iniciativa do cientista e do restaurador e, assim, constitui barreira a mais a dificultar a descoberta de soluções inovadoras e, especialmente, a retardar a expansão das áreas restauradas. Do ponto de vista da conservação da biodiversidade, considera-se que a indução de demanda comercial de material biológico de espécies raras ou ameaçadas, prevista na Resolução, pode colocar em risco a conservação das populações naturais dessas espécies, que deveriam ser alvo de programas específicos. Não parece, em suma, que a instituição dessa Resolução tenha contribuído para acelerar o ritmo de ampliação das áreas restauradas e tampouco para aumentar a probabilidade de sucesso das iniciativas de restauração.Palavras-chave: Legislação ambiental, Restauração ecológica e Resolução SMA 08.
