Deux Couleuvres à collier adulte (Diadophis punctatus edwardsii) ont été trouvées au parc national du Saguenay, dans l’est du Québec, en 2004 et 2005. Ces mentions se retrouvent à près 150 kilomètres au nord-nord-est de la mention la plus proche de l’espèce. L’habitat est constitué de forêt mixte près d’escarpements rocheux, dans des vallées. Il pourrait s’agir de populations isolées de celles retrouvées plus au sud.Two Ringneck Snakes (Diadophis punctatus edwardsii) was found in the Saguenay National Park, in eastern Québec, in 2004 and 2005. These records are about 150 kilometers north-north-east from the nearest previous record. The habitat is mixed forest, with rocky cliffs, in valleys. They may represent isolated populations from those found in southern Quebec.

Accurate measures of animal population densities are essential to evaluate conservation status and implement action plans to ensure species survival. Gorilla numbers were assessed using the recce survey method within Moukalaba-Doudou National Park (MDNP) in Gabon using fresh nest counts of up to 1 week old. We walked 3,592 km within a 23.01-km<sup>2</sup> study site totalling a sampling effort of 297 days. Encounter rate was 0.12 fresh nests per kilometre, and gorilla density estimates generated by home range sizes (by minimal convex polygon) ranged between 1.14 and 1.48 gorillas/km<sup>2</sup>. Gorillas preferred mixed forest for nesting over other habitats (Cheason index value 1.31). Results showed that gorilla density values within the study area concurred with previous studies that used line transect methodologies. We conclude that the choice of sampling design is dependent on environmental conditions characterised by each habitat type and target species.

We describe six new species of Melastomataceae from the Yanachaga-Chemillén National Park and surrounding areas from the Department of Pasco, Province of Oxapampa in Central Peru. Macrocentrum andinum is the first species of the genus described from the Andes, found along creeks at 400–500 m elev. and characterized by its anysophyllous leaves, pubescent stems and four-merous flowers. Meriania rubriflora is found in forests above 2200 m elev. and it is characterized by stem nodes with stipular flaps, leaves with an acute base and four merous, deep red flowers. Miconia palcazuana is found along rivers and streams at 300–400 m on the eastern flank of the park, and it can be distinguished by its flowers with pink anthers with glands on the connective and narrowly oblanceolate to elliptic-lanceolate leaves. Miconia yanachagaensis grows in the dwarf-sclerophyllous forests at the top of ridges and grasslands over 2800 m elev. and it is characterized by its long dendritic-pedicellate trichomes on the abaxial leaf surface, the stems flattened to terete and the presence of a conspicuous annular nodal line. Triolena rojasae is found growing on rocks along the Palcazú River and its tributaries, and it is characterized by its lanceolate-crenate leaves. Triolena vasquezii grows on the northern end of the Huancabamba canyon and the North East portion of the park and can be distinguished by its pustulate leaves with purple abaxial surface and anthers with two ventral appendages. We also present the first report of the genus Wurdastom for Peru.

Effective Conservation

Effective conservation of Sloth bear requires detailed information regarding their distribution and habitat use. This study attempted to generate baseline data on distribution and habitat preference of Sloth Bear in Chitwan National Park, Nepal during March–May 2012. The study area was divided into 74 grids each measuring 16 Km2. Of the total grids, 35 were randomly selected for occupancy sampling. A total of 288 spatial replicates were sampled in 35 different grids recording 87 direct or indirect evidences of Sloth bear. Among them, 50 diggings, 25 scats, four scrapes with live animals in eight points were detected in four different habitat types of the Park. The variance to mean ratio showed clumped distribution of Sloth bear. The RPI values revealed that the mixed forest was found to be most preferred (RPI = 0.42) by Sloth Bear followed by grassland (RPI = 0.21). Riverine forest and Sal forest were less preferred (RPI = -0.25 and -0.11 respectively) but not avoided. Distribution of Sloth bear was influenced by distance to nearest water sources, distance to road and altitude. Similarly, disturbances like human activities, presence of cattle and fi re were found to affect the distribution of Sloth bear.J. Nat. Hist. Mus. Vol. 28, 2014: 9-17

SummaryThe Volcanoes National Park (VNP) in Rwanda, part of the Virunga massif in the Albertine Rift region, boasts some of Rwanda’s best remaining natural vegetation and is home to many endangered and endemic species. The park has suffered from high levels of degradation and destruction, reducing in size by 50% during the 1960s and 1970s, and remains under threat from illegal activities, human population pressure and climate change. This study is the first to investigate the status and trends of bird communities in the VNP, using a multi-year dataset. We use a five-year dataset, totalling over 3,200 point-counts, both within and around the VNP, to assess the conservation value of the VNP for birds in comparison with other national parks and non-protected areas. We assess bird communities and population trends within and around the parks and identify important habitat factors for birds within the VNP. We found that the VNP hosts a unique bird community compared to other localities, with several Albertine Rift endemics and threatened species occurring in the VNP. Hagenia/ Hypericum woodland, herbaceous vegetation, brush ridge and mixed forest host the highest levels of bird diversity in the VNP, whilst the park’s waterbodies provide key habitat for the endangered Albertine Rift endemic Grauer’s Swamp-warbler (Bradypterus graueri). Elevation had a negative effect on bird diversity in the VNP, whilst the basal area of dead trees, Hagenia and vines had a positive effect. Both inside and outside the VNP, there was a significant decline in abundance and species richness over the sampling years; however, we advocate for further monitoring to confirm these trends. Based on our findings, we recommend effective, targeted management of key habitats for birds within the park, including those identified in this study, in order to mitigate bird declines and conserve the unique bird communities in the VNP.

The Letaba River drains part of Northern Province in north-east South Africa. Its catchment has been modified significantly by human activity which has affected the flow regime; it experiences only ephemeral flows through the Kruger National Park to its confluence with the Olifants River. Although the Letaba is similar to the other rivers in the Kruger National Park in that it displays some bedrock influenced channel features, increased sediment delivery from the degraded catchment upstream has resulted in extensive alluviation within the channel. Sections of channel flowing over bedrock with no sediment covering are rare, and the river comprises a series of channel types: mixed anastomosing, alluvial braided, mixed pool-rapid and alluvial single thread. Each is characterised by a different combination of morphological units which relate to the degree of alluviation in the channel. These channel types are described in detail and inferences are made concerning their formation and maintenance from field observation and measurement.

The flood extent in the lower Biebrza basin calculated by the 1D flow model for different land use scenarios The flood extent in the lower Biebrza basin calculated by the 1D flow model for different land use scenarios. An application of an steady 1D flow model for determination of a flood extent in the natural river valley is discussed in this paper. The Pasche method was used to calculate the total Darcy-Weisbach friction factor for each cross section according to the type of vegetation and flow interaction between the main channel and vegetated areas. In this approach friction caused by interaction between the main channel and vegetated areas are taken into account. The model was applied to the Biebrza Valley, fairly undisturbed river-marginal peatland, located in the north-east of Poland. Actual land use carried out in the National Park was analyzed to determine the influence of changes in the vegetation structure on the flood extent in the river valley. The obtained results show variation of a flooded area in relation to the vegetation of the floodplain.

White Rhino

The northern race of the square-lipped rhinoceros Ceratotherium simum cottoni is disappearing in Africa and is now believed extinct in Uganda. Commonly called the white rhinoceros because of its wide (weit) square mouth, it differs from the black rhino in size, habits and disposition. The white rhino occurred naturally in three countries: the West Nile Province of Uganda, north-east Zaire, and the Bahr el Ghazal and Equatorian provinces of Sudan. The Nile limited its eastern spread, although fossils show that it existed in Tanzania some 400,000 years ago. Its extreme southern limit was the river Ora which enters the Nile opposite Wadelai, from where it extended northwards along the western bank of the Nile through to Shambe, and then north-west through the Bahr el Ghazal drainage to the borders of Chad, where in the 1890s it was abundant. Harper reported the collection of many rhino horns yearly in Abecher. At the beginning of this century Sidney described the species as numerous in the upper waters of the Bahr Azoum and the Bahr Aoule, plentiful in the Birao area, fairly numerous north of the Uele river in what is today in Zaire's Garamba National Park, and abundant in Okolo, Aringa and West Madi in Uganda.18Rhinos were so common in all these areas that in 1919 Theodore Roosevelt's headquarters for the Smithsonian African Expedition collecting rhino products was named Rhino Camp. Here in 1932 Captain Pitman encountered 30–40 groups of at least seven individuals each within a day's walk, and he could approach to within 7–8ft because they were unharried by hunters and poachers.

Teinopalpus imperialis an endangered swallowtail butterfly of high conservation value is encompassed into the Appendix II of CITES (Convention of International Trade of Endangered Species). This butterfly prefers its habitat at the altitudinal range of 2180 - 3000 m and emerges out for a brief period in summer months of May till July first week annually. This target species dwells in the broad leaved evergreen and mixed forest of Oaks (Quercus spp.). This specific work made an extensive study of Teinopalpus imperialis with respect to its population status, associated habitats and prevailing threats in Phulchoki Mountain (Lalitpur District), Nagarjun –Shivapuri National Park (Kathmandu District) and Nagarkot Mountain (Bhaktapur District). This revealed out the occurrence of 21 individual populations of this butterfly in the Phulchoki Mountain and 8 individuals in the Nagarjun forest. Nagarkot of Bhaktapur district did not represent any of this species due to prevailing high impact on its habitat area.J. Nat. Hist. Mus. Vol. 28, 2014: 49-56
