Résumé :
This paper presents the results of a mammal survey conducted between 1995 and 1997 in the newly established National Park of Upper Niger in the Republic of Guinea, West Africa. Ninety-four species of mammals were recorded in the park area and its environs; 19 of these species were newly recorded or confirmed for Guinea. The fauna of the park includes about 50% of the known mammalian diversity of the country. Among the species found are West African endemics such as the Gambian mongoose Mungos gambianus. The park, although situated in the Guinea savannah belt, includes some remnant forest, whic

During the spring of 2016 and 2017, the Mersey Tobeatic Research Institute (MTRI), in collaboration with the Nova Scotia Department of Fisheries and Aquaculture, conducted an angler creel survey in the Medway Lakes Wilderness Area that is located within the upper Medway watershed. Since 2012, public access to this region was improved to numerous lakes and streams, increasing the risk of overexploitation and the illegal introduction of invasive fish species. The purpose of this study was to assess the current status of the fishery for Brook trout, Salvelinus fontinalis, investigate the possible

Résumé :
The establishment that 70% of the world's poor residing in rural areas depends directly on biodiversity for their well-being has ignited the call for sustainable usage of biological resources. Biodiversity conservation has thus become a novel project with noble intention of providing a habitat and protection from hunting for threatened and endangered species and ecological processes that cannot survive in most intensely managed landscapes. Nigeria has created protected areas under the coordination of National Park Services in line with this. As a result, residents of communities surrounding the protected areas could not meet their basic needs like employment, water provision, educational facilities, medical services, energy supply, livestock grazing, and motorable roads. They have subsequently deviated from the extant rules that guide their conducts and by ensuing difficulties see biodiversity conservation as an elitist policy despite their understanding of the idea behind it.

Résumé :
&lt;i&gt;Abstract&lt;/i&gt;.—The primary mission of the U.S. National Park Service is to protect and preserve native species. Control of nonnative species is also a principal management objective. Historic land management and stocking of nonnative Rainbow Trout &lt;i&gt;Oncorhynchus mykiss&lt;/i&gt; in Great Smoky Mountains National Park in the eastern United States resulted in native Brook Trout &lt;i&gt;Salvelinus fontinalis&lt;/i&gt; losing approximately 75% of their historic range. Consequently, the park initiated a program in 1976 to evaluate electrofishing for removal of Rainbow Trout in six small streams and found it to be successful upstream of impassable barriers. Later (mid-1990s), park biologists effectively used Fintrol (antimycin) to remove nonnative Rainbow Trout from low-elevation streams with impassable barriers. The National Environmental Policy Act and the Environmental Assessment process required public meetings be held in communities around the park prior to the use of Fintrol to explain the need for and purpose of these projects. In September 2008, Fintrol was used to renovate a large system—12.8 km (8 mi) of upper Lynn Camp Prong. Native Brook Trout were reintroduced in 2009, but monitoring efforts in 2010 revealed the presence of illegally stocked Rainbow Trout in upstream sections of the project area. Approximately 4.6 km (3.0 mi) of the project area was successfully retreated in 2011 to remove the reintroduced Rainbow Trout. Several public hearings were held successfully around the park to educate local residents about the Lynn Camp Prong project. Monitoring efforts during 2012–2015 showed that the Brook Trout population increased steadily, with abundance ultimately exceeding that of Rainbow Trout prior to restoration. Lessons learned are that (1) public education, buy-in, and involvement are crucial to success; (2) partnerships with state and federal agencies, local conservation groups, and the local community are essential; (3) fisheries professionals must be steadfastly committed to success and adaptable to changing conditions; and (4) restoration of native species can be controversial. If sabotage happens, reach out to the public, provide them with up-to-date information, and enlist their help.

This chapter explores the era of camping before the automobile came onto the scene. Camping persisted as a largely upper-middle-class and white activity during this time, but its popularity grew rapidly as magazine accounts, how-to manuals, and guidebooks taught more urban people how and where to camp. The chapter features a few camping advocates, including Horace Kephart, a tortured soul who became America's best-known camping author during the twentieth century's first decades. It also follows two camping parties—historian Frederick Jackson Turner out with his family on a month-long canoe trip to Ontario's Lake Nipigon and the writer Mary Bradshaw Richards, who with her husband traveled from Massachusetts to the young but distant Yellowstone National Park.

Résumé :
This study discusses adaptation effects and congestion in a multi-agent system (MAS) to analyse real transport and traffic problems. Both methodological discussion and an empirical case study are presented in this chapter. The main focus is on the comparison of an analysis of a MAS simulation analysis and an analysis that solely uses discrete choice modelling. This study explains and discusses some important concepts in design empirical MAS in traffic and transportation, including validation Minority Game and adaptation effects. This study develops an empirical MAS simulation model based on real stated-preference data to analyse the effect of a real road-user charge policy and a complimentary park and ride scheme at the Upper Derwent Valley in the Peak District National Park, England. The simulation model integrates a transport mode choice model, Markov queue model, and Minority Game to overcome the disadvantages of a conventional approach. The results of the simulation model show that the conventional analysis overestimates the effect of the transportation and environment policy due to the lack of adaptation affects of agents and congestion. The MAS comprehensively analysed the mode choices, congestion levels, and the user utility of visitors while including the adaptability of agents. The MAS also called as agent-based simulation successfully integrates models from different disciplinary backgrounds, and shows interesting effects of adaptation and congestion at the level of an individual agent.

Résumé :
&lt;em&gt;Abstract&lt;/em&gt;.—Native fish conservation areas (NFCAs) are watersheds where management emphasizes proactive conservation and restoration for long-term persistence of native fish assemblages while allowing for compatible uses. Native fish conservation areas are intended to complement traditional fisheries management approaches that are often reactive to population stressors and focused on single-species conservation efforts rather than complete assemblages. We identified potential NFCAs in the upper Snake River basin above Hells Canyon Dam using a process that ranked all subwatersheds (Hydrologic Unit Code 12) and used empirical data on distribution, abundance, and genetics for three native trout species (Bull Trout &lt;em&gt;Salvelinus confluentus&lt;/em&gt;, Columbia River Redband Trout &lt;em&gt;Oncorhynchus mykiss gairdneri&lt;/em&gt;, and Yellowstone Cutthroat Trout &lt;em&gt;O. clarkii bouvieri&lt;/em&gt;, including the fine-spotted form) and both known occurrences and modeled potential distributions of native nongame fishes. Rankings also incorporated drainage network connectivity and land-protection status (e.g., national park, wilderness). Clusters of high-ranking subwatersheds were identified as potential NFCAs that were then classified according to the presence of nongame fishes identified as species of greatest conservation need in state wildlife action plans. The Pacific Creek and Goose Creek watersheds ranked high in the upper basin (above Shoshone Falls), and Little Jacks Creek and Squaw Creek ranked high in the lower basin. We then contrasted characteristics of a select few potential NFCAs, discuss the practical implementation and benefits of NFCAs for both fishes and other aquatic species in the upper Snake River basin, examined how the NFCA approach could enhance existing conservation partnerships, and discuss how designating select watersheds as NFCAs can create higher public awareness of the value of native fishes and other aquatic species and their habitats.

Texte intégral
Résumé :
Rock slopes developed in granite may take different forms, as reflected in their longitudinal profiles. Field observations and a literature survey (e.g. Dumanowski, 1964; Young, 1972) allow us to distinguish at least five major categories of slopes: straight, convex-upward, concave, stepped, and vertical rock walls. In addition, overhang slopes may occur, but their height is seldom more than 10 m high and their occurrence is very localized. These basic categories may combine to form compound slopes, for example convex-upward in the upper part and vertical towards the footslope. Somewhat different is Young’s (1972) attempt to identify most common morphologies of granite slopes. He lists six major categories: (1) bare rock domes, smoothly rounded or faceted; (2) steep and irregular bare rock slopes of castellated residual hills, tending towards rectangular forms; (3) concave slopes crowned by a free face; (4) downslope succession of free face, boulder-covered section and pediment; (5) roughly straight or concave slopes, but having irregular, stepped microrelief; (6) smooth convex-concave profile with a continuous regolith cover. The latter, lacking any outcrops of sound bedrock, are not considered as rock slopes for the purposes of this section. Young (1972) appears to seek explanation of this variety in climatic differences between regions, claiming that ‘Variations of slope form associated with climatic differences are as great as or greater, on both granite and limestone, than the similarity of form arising from lithology’ (Young, 1972: 219). This is a debatable statement and apparently contradicted by numerous field examples of co-existence of different forms in relatively small areas. Slope forms do not appear specifically subordinate to larger landforms but occur in different local and regional geomorphic settings. For example, the slopes of the Tenaya Creek valley in the Yosemite National Park include, in different sections of the valley, straight, vertical, convex-upward, and concave variants (Plate 5.1). Apparently, multiple glaciation was unable to give the valley a uniform cross-sectional shape.

By mid-March, daytime temperatures above freezing have left muddy puddles all over the unpaved road that runs above and beside the beaver meadow. This road extends to the national park trailhead farther upstream but is now closed for winter. I enter the beaver meadow on a lightly overcast day that is windy, as I expect March to be. Lack of recent snowfall and warm temperatures have caused the snowpack to shrink down, and I no longer break through into hidden pockets of air around the base of the bushy willows. I do break through the ice on my snowshoes, sinking in a slow motion that allows me to scramble and keep my feet dry . . . mostly. I sink in above the ankle at one point and the resulting icy ache makes me appreciate the ability of beavers to stay warm. The snow covering the higher peaks and the adjacent lateral moraines appears about the same, but numerous spots of bare ground have appeared along the creek banks. The remaining snow resembles a blanket draped over the undulating, grassy ground rather than an integral part of the landscape. I stand on the snowbank at the downstream end of one of the larger beaver ponds. The dam merges into a vegetated berm and appears to be intact, but I can hear water flowing swiftly somewhere beneath the snow. Most puzzling is that I can’t see where the water is going: the nearest downstream standing water has no apparent inflow or current. Mysterious, intricate plumbing surrounds me. The beaver meadow is on the move, flowing and changing, preparing for the season of birth and growth. Standing water is noticeably more abundant than a month ago. Interspersed among the ice and snow are big puddles and little ponds, some connected and draining, others isolated and still. The still pond waters have a shallow covering of meltwater underlain by ice with large, irregularly shaped air pockets trapped in the upper layer. These I can easily break with the tip of my ski pole. Thousands of tiny bubbles deeper in the ice look milky.

Résumé :
The Southeast Coast Network (SECN) Wadeable Stream Habitat Monitoring Protocol collects data to give park resource managers insight into the status of and trends in stream and near-channel habitat conditions (McDonald et al. 2018a). Wadeable stream monitoring is currently implemented at the five SECN inland parks with wadeable streams. These parks include Horseshoe Bend National Military Park (HOBE), Kennesaw Mountain National Battlefield Park (KEMO), Ocmulgee Mounds National Historical Park (OCMU), Chattahoochee River National Recreation Area (CHAT), and Congaree National Park (CONG).
