This study provides a first checklist of the native vascular plant taxa of Djurdjura National Park, based on collections and field visits (2011–2015), with an analysis of its composition and species diversity. The results of floristic analysis outlines the main characteristics of the flora of Djurdjura National Park. It hosts a remarkable species diversity of 757 plant taxa (including 659 species, 95 subspecies, 2 varieties, and 1 forma) belonging to 381 genera in 88 families. Despite covering ca. 0.008% of the total area of Algeria, this national park protects about 17% of the vascular plants of the country. The most represented families are Asteraceae, Fabaceae, Poaceae, Lamiaceae, Apiaceae, Caryophyllaceae, Rosaceae, and Brassicaceae, while the most represented genera are Trifolium (with 15 taxa) and Silene (12). Hemicryptophytes (37.25%) and therophytes (30%) are the most represented life forms among the local flora, a pattern typical of mountainous areas. Mediterranean taxa comprise 64.6%, followed by North African taxa (14%), European (7.53%), and widely distributed taxa (13.87%), which reveals the Mediterranean character of the mountain’s flora. The endemic flora of Djurdjura National Park contains 106 taxa (14%), of which 20 are endemic to Algeria. In addition, six are exclusive and range-restricted to the Djurdjura National Park. Hence, we emphasized a large number of priority taxa (30) of high conservation value. The presence of exclusive endemics, and threatened species, along with high floristic diversity, strengthen the importance of plant conservation in the studied area.

Species diversity of plants was recorded in 1992 and 1993 at seven stations of the “Evolution Canyon” microsite. Higher solar radiation on the South-Facing Slope (SFS) causes warm, xeric savannoid formation versus temperate, cool, mesic, dense maquis on the North-Facing Slope (NFS), and riverine, segetal plant formations on the Valley Bottom (VB). In an area of 7000 m2, we recorded 320 vascular plant species in 217 genera and 59 families. Plant cover varied from 35% (SFS) to 150% (NFS). Annuals predominated among all life forms (61.3% of all species). SFS and NFS varied in species content, sharing only 31–18% of species. Phytogeographical types varied among the two slopes and valley bottom. Inter-and intraslope species composition varied drastically due to differential microclimatic stresses, thereby demonstrating at a microscale natural selection in action.

History Of

Covering an area of 177,000 hectares, the region known within Belize as the Chiquibul Forest comprises the country's largest forest reserve and includes the Chiquibul Forest Reserve, the Chiquibul National Park and the Caracol Archaeological Reserve. Based on 7047 herbarium and live collections, a checklist of 1355 species of vascular plant is presented for this area, of which 87 species are believed to be new records for the country. Of the 41 species of plant known to be endemic to Belize, four have been recorded within the Chiquibul, and 12 species are listed in The World Conservation Union (IUCN) 2006 Red List of Threatened Species. Although the Chiquibul Forest has been relatively well collected, there are geographical biases in botanical sampling which have focused historically primarily on the limestone forests of the Chiquibul Forest Reserve. A brief review of the collecting history of the Chiquibul is provided, and recommendations are given on where future collecting efforts may best be focused. The Chiquibul Forest is shown to be a significant regional centre of plant diversity and an important component of the Mesoamerican Biological Corridor.

The phytogeographic patterns displayed by the 550 rare vascular plant taxa in Ontario, including 349 that are rare nationally, are correlated with counties, site regions, and floristic provinces. Rare taxa are concentrated in southwestern Ontario decreasing northward, with secondary concentrations along the Hudson Bay coast. Rare taxa in Ontario are predominantly peripheral taxa, which have their main ranges outside of Ontario. Many of these taxa, however, have a high Canadian conservation priority because they are also at risk in adjacent states or provinces. Rare taxa with Appalachian and Coastal Plain affinities are most common in southwestern Ontario. Arctic and boreal affinities predominate in Northern Ontario. These patterns are correlated with temperature and moisture parameters, which are incorporated with the Hills' site regions classification. Most high conservation priority taxa occur in the Carolinian region, the most highly settled and most highly agriculturalized part of the province. There is an urgent need for conservation of the remaining forest and wetlands in this region. The fragmentary ecosystems still remaining must be protected from further development. There is a need to study the correlation of rare plant occurrences with existing parks and reserves throughout the province to facilitate the identification of priority regions for protection. Key words: rare plants, phytogeography, conservation, Ontario.

Open mining of sand is executed in the sand pits. After completion of the work sand pits are usually recultivated: firstly they are graded and then planted with trees and shrubs, but very often sand pits are abandoned to regenerate themselves. The sand pit becomes a source of dust and a hardly healed wound on the earth’s body. In order to provide an adequate revegetation on such substrates, it is necessary to study biomorphological peculiarities of growing plants in a very specific environment characterized by high stiffness of slopes and high mobility of the substrate. The material for our study collected from Moscow Region sand pits in the Russian federation. Plants were collected from both northern and southern exposure slopes. Our work is based on the geobotanical descriptions made according to standard method on experimental sites of 5x5 m2. The results of the undertaken shows that Compositae, Gramineae, Fabaceae are the most representative of the surveyed one hundred twenty seven species of higher vascular plants from 29 families. Diversity on the southern slopes was more than on the northern ones. Species diversity is determined by the successions occurring spontaneously after a rough anthropogenic intervention, under the influence of such environmental factors as lighting, moisture, texture and richness of soil. The spectrum of life forms showed that the overwhelming majority according to K. Raunkiru are hemicryptophytes. Perennial herbaceous polycarpics are dominant in the spectrum of life forms, according to I.G. Serebryakov.

Comprehensive Study

Abstract The paper presents composition of vascular plant species in spring niches in the Ojców National Park (Southern Poland). 111 species of vascular plants, fourteen mosses, two liverworts and one species of ferns were recorded during the first comprehensive study carried out in 2009 and 2010. Plants occurring in these places showed different degrees of association with spring niches. The largest group was represented by accidental krenophytes (74 species), while spring plants - obligatory krenophytes, constituted only a small part of the local flora (5 species). Meadow species of the Molinio-Arrhenatheretea class and forest species of the Querco-Fagetea class, penetrating niche areas from the adjacent areas, were the dominating ones. Plants of aquatic and spring communities were scarce, due to the predominance of small type karst springs. The diversity of vegetation was significantly influenced by habitat factors such as availability of light, humidity or the amount of organic matter in the soil.

Broad Scale

A broad-scale floristic inventory of all vascular plants was proposed for Grand Teton National Park and the John D. Rockefeller Jr. Memorial Parkway (JDR) primarily to document the extant flora in remote backcountry areas. The Teton Mountains are floristically important because of the unique habitats which they contain, because their relatively undisturbed (human disturbance) condition, and because of their proximity to the Yellowstone Plateau, a floristically unique area of Wyoming. Many studies have explored these lands for purposes of vegetation characterization (Cogan et al. 2005, McCloskey 2006) though an explicit and complete plant inventory parkwide had never been undertaken.

Abstract The paper presents results of a first attempt to survey bats of the Alatish National Park (northwestern Ethiopia). Twenty-one bat species belonging to eight families and twelve genera were documented for the first time in the Park, at least two bat species (Hipposideros abae, Pipistrellus nanulus) were found new for the fauna of Ethiopia. The Alatish National Park is an area of high conservation value due to its high bat species diversity and a complex structure of the fauna including elements with various zoogeographic affinities.

In order to identify concordant distributions of endemic vascular plants in the Monte desert, we analyzed the distributional data of 180 species endemic to the Monte desert with the optimality criterion implemented in the program VNDM. We detected 13 partially overlapping areas of vascular plant endemism.The main areas of endemism are distributed from north to south associated with the mountainous region of the Precordillera of the Andes towards the west of the study region. These main areas correspond to environments with important variation in elevation and aridity, whereas minor areas correspond to patches of the steppe vegetation towards the east of the study region. We also obtained extensive areas covering much of the Monte desert, coincident with the two classical biogeographic units proposed.  In agreement with the general arid climate of the Monte, most of the endemic flora inhabits arid and/or semiarid environments.

This paper presents the first comprehensive checklist of vascular plants for an especially important area for biodiversity, namely National Park “Ethnikos Drymos Oitis” – Natura 2000 site (GR2440004) and the surrounding area in Greece. This list includes a total of 1,153 plant taxa, including 79 endemic taxa and two local endemic species (Allium lagarophyllum Brullo, Pavone & Tzanoudakis and Veronica oetaea Gustavsson). It is noteworthy that 551 plants are new records for the flora of Mt. Oiti. A total of 67 taxa are protected by national and international legislation, while 52 orchid taxa are also protected by the Convention of International Trade in Endangered Species of Wild Fauna and Flora (CITES). Veronica oetaea, a priority species of Annex II of the Directive 92/43, is also protected by the Berne Convention. The high plant species diversity and endemism make Mt. Oiti National Park an important area with high conservation value, thus providing baseline information which could be utilized for further research.
