The aims of this work were to describe the conservation status of riparian forests located in a mountain subtropical basin of Tucumán province, Argentina, and assess how the quality of riparian forests is related with altitude, plant species richness, proportion of exotic species, and Total Suspended Solids (TSS) in adjacent rivers. Composition and species richness of riparian forests were studied at 16 sites located along an altitudinal gradient and TSS was determined from water samples collected in each site. In order to evaluate conservation status of riparian forests, we calculated an index of Quality of Yungas Riparian Forests (QBRy). We recorded 90 plant species at all sites, from which 77% were native. QBRy index was mainly associated with altitude and varied from riparian forests with good preservation or slightly disturbed to those with extreme degradation. At lower altitude, forests were more disturbed, more invaded by exotic plant species, and closer to urban and cropped areas. QBRy was not correlated with species richness or TSS. Like other riparian forests of Argentina, plant species invasion increased their degradation; therefore, future studies should focus on native riparian forests conservation and on the management of invasive plant species, which affect their quality.

Nurfadilah S, Hapsari L, Abywijaya IK. 2017. Species richness, conservation status, and potential uses of plants in Segara Anakan Area of Sempu Island, East Java, Indonesia. Biodiversitas 18: 1568-1588. Sempu Island is a small Island in Indonesia that has an important functional role as a nature reserve to protect unique landscapes and high plant species richness. Within the Island, one of the most frequently visited areas, Segara Anakan, needs careful attention in order to conserve its plant diversity. The objectives of the present study were to investigate the species richness, conservation status, and potential uses of plants in Segara Anakan, Sempu Island. The aim was to support management of the area and to reveal plants that have potential to be developed for useful products. A total of 77 plant species belonging to 43 families were recorded within the study area. These consisted of trees (55.84 %), shrubs (33.77%), herbs (9.09%) and epiphytes (1.3%). Two species were listed in the IUCN Red List as endangered (Cycas circinalis L. and Myristica teijsmannii Miq.). Plant species in Segara Anakan have many potential uses; namely for staple food, fruits, vegetables, flavouring, beverages, herbal medicines, timbers, ornamental plants, natural dyes, and other uses. The study has implications for biodiversity conservation and management of Sempu Island. Plant species on the IUCN Red List should receive priority in conservation efforts. Data concerning the potential uses of plants can serve as a basis for biodiversity conservation on Sempu Island.

AbstractIn the intensively farmed, homogenous agricultural landscape of the North China Plain, family graveyards form distinct cultural landscape features. In addition to their cultural value, these graveyards represent semi-natural habitat islands whose potential roles in biodiversity conservation and ecological functioning has remained poorly understood. In this study, we investigated plant species richness on 199 family graveyards of different ages and sizes. In accordance with biogeography theory, both overall and insect-pollinated plant species richness increased with area and age of graveyards. Even small graveyards show a strong potential for conserving local plant richness, and a mosaic of both large and small family graveyards could play an important role in the conservation of farmland biodiversity and related ecosystem functions. The launch of agri-environmental measures that conserve and create semi-natural habitats, in turn benefitting agricultural biodiversity and ecological functioning, has proven difficult in China due to the shortage of dispensable arable land. Given the great value of family graveyards as semi-natural habitats reflected in our study, we propose to focus preliminary efforts on conserving these landscape features as existing, widespread and culturally important semi-natural habitat islands. This would represent an effective, complementary policy to a subsequent re-establishment of other semi-natural habitats for the conservation of biodiversity and ecological functioning in agricultural landscapes.
