Inventory of ferns and lycophytes within forest fragments of Araucaria in southern Brazil

The Araucaria Forest is a unique plant formation, practically restricted to the Atlantic Forest biome, in the South and Southeast of Brazil. It is immensely fragmented and its area is reduced to a minimum fraction, from 13 to 2% of the original area, due to intense anthropic exploitation. Our study evaluated the richness and floristic composition of ferns and lycophytes within three Araucaria forest fragments, in Rio Grande do Sul, Brazil. For the floristic inventory, a parcel of 1 ha (100x100m) was demarcated inside three fragments, which were classified by size: large (246 ha - H1LF), medium (57 ha - H2MF) and small (5.2 ha - H3SF). Occurring species life forms and preferential substrates up to 4 meters above ground were recorded. In total, 55 species were catalogued, only two of which were lycophytes, distributed in 32 genera and 17 families. Considering the area of fragments, the recorded species richness has decreased, presenting greater numbers in H1LF (48), followed by H2MF (33), and H3SF (29). In the three sites, terrestrial substrate and the hemicryptophyte species life form predominated. We observed that one hectare of a larger forest fragment presented 65% more species than that of a smaller one, considering that the smaller fragment total area represents only 2% of the larger forest's area. On the other hand, one hectare of the smaller fragment contributed 17% to fern and lycophyte species conservation occurring in Brazilian Araucaria Forests, and 8% to the state of Rio Grande do Sul's total richness. The diverse heterogeneity and species composition grants floristic identity to each of the studied forest interiors. Our results highlight the need to include the botanical parameters here analyzed in management, conservation degree evaluation, and maintenance of Araucaria Forests plant biodiversity.

Resumo Os resultados aqui apresentados fazem parte de um trabalho maior que consiste na Flora Vascular da Pedra do Elefante, Nova Venécia, Espírito Santo. As expedições a campo foram realizadas de março de 2010 a julho de 2016, em um total de 23 visitas ao local. As amostras foram incorporadas principalmente nos herbários CEPEC, MBML, RB, UPCB, VIC e VIES. Sessenta e três espécies, uma subespécie, três variedades e dois híbridos de samambaias e licófitas foram registradas, distribuídas em 32 gêneros e 15 famílias. As famílias mais representativas foram Pteridaceae (14 spp.), Polypodiaceae (11 spp.), Anemiaceae (9 spp.) e Selaginellaceae (5 spp.). Os gêneros mais representativos foram Anemia (9 spp), Selaginella (5 spp.), Adiantum e Pteris (4 spp. cada). Dentre estas, três espécies são novas ocorrências para o Espírito Santo e oito táxons apresentam estado de conservação. Chaves de identificações em nível genérico e específico, comentários, e distribuição geográfica para todos os táxons são apresentados. Inventários florísticos no Espírito Santo são importantes, principalmente em áreas que possuem afloramentos rochosos, pois o baixo esforço de amostragem e a alta pressão antrópica, causam impactos negativos na preservação da vegetação nativa.
