“…2022 individuals (1,590.4 ind.ha -1 ) smaller than has been reported in most phytosociological surveys undertaken in crystalline caatinga sites: 2,448 ind. ha -1 by Santana & Souto (2006); 2,448 ind.ha -1 by Pereira-Júnior et al (2012); and 4,822 ind.ha -1 by Lima et al (2019). Similar surveys undertaken by Rodal et al (1992) (1,076 ind.ha -1 ) and Lacerda & Barbosa (2018) (1,623 ind.ha -1 ), however, likewise reported low plant densities in that habitat.…”

The Seasonally Dry Tropical Forests and Woodlands biome (SDTFW) has its largest nucleus in the Caatinga domain. We characterized the flora and physiognomy of the vegetation in the Pedra da Andorinha Wildlife Refuge (RPA), in Ceará, Brazil. Plant collections were made between March/2015 and May/2021, applying usual botanical methods. All material was deposited in HUVA herbarium. The phytosociological studies covered five 50 m x 50 m plots established (1.25 ha) in which all individuals with diameters at soil level ³ 3 cm were inventoried. We identified 266 vascular plants species distributed among 185 genera and 67 families, including one fern (Marsilea deflexa - Marsileaceae). Fabaceae had the greatest species richness (38 spp.), while Ipomoea was the richest genus (9 spp.). 43.6% of all plant species were herbaceous, with a predominance of therophytes (57.5% of all herbaceous plants). The phytosociological study sampled 1,988 individuals distributed among 24 species of 13 families. The species with the greatest important value were Cordia oncocalyx (Boraginaceae) and Croton blanchetianus (Euphorbiaceae). We classify the local physiognomy as typical caatinga sensu stricto vegetation and rocky vegetation on inselbergs and outcrops. We highlight the richness of herbaceous plants in the local community, which surpass the richness of the woody component.

“…Segundo Araújo, Silva, Ferraz, Sampaio e Silva (2005), essas formas de vida são recorrentes em microhabitats que estão inseridas no domínio da Caatinga. Lima et al (2019) em uma área de Caatinga no Cariri Paraibano, enfatizaram a relevância da presença de espécies pertencentes a família Malvaceae na fitossociologia das plantas lenhosas e herbáceas na RPPN Fazenda Almas, onde o componente herbáceo apresentou maior riqueza e a família Malvaceae obteve o maior número de indivíduos. Ramos et al (2020) em seu levantamento florístico realizado nas margens do Rio Espinharas, Rio Farinha e Rio da Cruz na cidade de Patos-PB, ratificaramou na sua composição florística a presença considerável de espécies da família Malvaceae que foi a segunda família com maior quantidade de espécies, sendo predominantemente herbáceas.…”

A Área de Proteção Ambiental (APA) da Lagoa da Maraponga é uma unidade de conservação municipal localizada no bairro Maraponga, município de Fortaleza, estado do Ceará. Composto predominantemente por um ecossistema lacustre, no qual se destaca a Lagoa da Maraponga, com área de 31 hectares, ameaçada pela ação antrópica, fazendo com que a conservação se torne uma prioridade. Objetivou-se fazer o levantamento florístico da APA da Lagoa da Maraponga e elaborar um guia de campo. Foram realizadas coletas botânicas, observações de campo, fotografias e identificações das espécies. Registraram-se 98 espécies pertencentes a 82 gêneros e 37 famílias botânicas. As famílias mais representativas foram Fabaceae (18 spp.), Malvaceae (13 spp.), Asteraceae (dez spp.), Rubiaceae (cinco spp.), Arecaceae, Convolvulaceae e Solanaceae (quatro spp., cada). Constatou-se que o hábito das espécies tem como predomínio o porte herbáceo (41 spp.), seguido de espécies subarbustivas (19 spp.), arbóreas (17 spp.), arbustivas (dez spp.), trepadeiras (sete spp.) e palmeiras (quatro spp.). Conclui-se que esta área tem demonstrado que mesmo com a interferência humana e o grande avanço da urbanização em seus arredores, a flora local apresenta elevada riqueza de espécies nativas que precisa ser conservada, mantida e reconhecida por políticas públicas e pela sociedade, as quais podem ser auxiliadas pelo guia de campo elaborado. Floristic Survey of the Environmental Protection Area (EPA) of Maraponga Lagoon, Fortaleza, Ceará, Brazil A B S T R A C TThe Maraponga Lagoon Environmental Protection Area (EPA) is a municipal conservation unit located in the Maraponga neighborhood, in the municipality of Fortaleza, state of Ceará. Composed predominantly of a lake ecosystem, in which the Maraponga Lagoon stands out, with an area of 31 hectares, threatened by anthropic action, prioritizing conservation. The objective was to carry out the floristic survey of the EPA of Maraponga Lagoon and to prepare a field guide. Botanical collections, field observations, photographs and species identification were carried out. A total of 98 species belonging to 82 genera and 37 botanical families were registered. The most representative families were Fabaceae (18 spp.), Malvaceae (13 spp.), Asteraceae (ten spp.), Rubiaceae (five spp.), Arecaceae, Convolvulaceae and Solanaceae (four spp., each). It was found that the habit of the species predominates the herbaceous size (41 spp.), followed by sub-shrubs (19 spp.), trees (17 spp.), shrubs (ten spp.), climbing plants (seven spp.) and palm trees (four spp.). It’s concluded that this area has shown that even with human interference and the great advance of urbanization in its surroundings, the local flora has a high number of native species that need to be conserved, maintained and recognized by public policies and society, which can be assisted by the field guide prepared.Keywords: Urban biodiversity, conservation, vegetable diversity, richness, conservation unit.

“…This makes the ecology of Caatinga different from, the savanna vegetation, where the herbaceous layer is perennial. The flora of Caatinga is represented by approximately 3.347 species, of which at least 526 are endemic, with a high proportion of herbaceous species observed, although this component is commonly neglected in studies carried out on this vegetation Lima et al 2019;Fernandes et al 2020). Seasonally dry tropical forests and woodlands have received attention from researchers in recent decades, as they have begun to reveal higher levels of species richness and endemism than previously expected (Moro et al 2015).…”

In the savanna-seasonally dry tropical forest ecotone in Northeastern Brazil, we studied variations in flora and structure within old growth and two sites in secondary succession (10 and 25 years). We sampled 2,127 trees and shrubs with a diameter at ground level of 3 cm or more, excluding cacti, palm trees, and vines. Old growth contained 478 plants from 29 species, the 25-year site had 819 plants from 27 species, and the 10-year site had 829 plants from 25 species, totaling 38 species across the sites. Regarding the regenerating stratum, we found 2,776 individuals, with the largest and smallest number of individuals for 10 and 25 years regeneration, respectively. Rarefaction and Jacknife richness showed greater tree richness in old growth, whereas 10 and 25 years regeneration presented similar richness estimates; furthermore, the highest richness in the regenerating stratum was observed in 10 years and the lowest in old growth. Our results reveal that changes in composition are caused by species replacement, demonstrating that even in areas deforested for traditional agriculture, turnover causes significant changes in composition and results in the requirement of a long time for reestablishment, similar to the old growth.
