“…We did not consider information on existing conservation areas in sub-Saharan Africa, information on cost, or the information on viability and threat for populations within realistic management areas that is necessary for ensuring the persistence of species (Pressey et al, 1993;Witting & Loeschcke, 1993;Lombard, 1995;Freitag et al, 1996;Howard et al, 1997;Nicholls, 1998;Williams, 1998 Itoua et al (1997); the five orders of larger mammal species (224 sub-Saharan species of Primates, Carnivora, Proboscidea, Perissodactyla and Artiodactyla); and all 2687 sub-Saharan mammal and breeding bird species records. With the exception of the histogram at the bottom, which shows all fully flexible sets, scores are taken from a randomly drawn sample of 1000 alternative fully flexible sets checked to ensure that they represent the same number of species from the groups used to make the selection.…”

More biodiversity could be protected in situ if the few species that attract the most popular support (the 'flagship' species) had distributions that also covered the broader diversity of organisms. We studied how well different groups of mammals performed for representing the diversity of mammals and breeding birds among 1°areas of sub-Saharan Africa. We demonstrate that choosing areas of sub-Saharan Africa using either conservationists' six primary flagship mammals, or the six 'Big Five' mammals popular with wildlife tourists, is not significantly better for representing the diversity of mammals and birds than choosing areas at random. Furthermore, neither of these groups is significantly better for representing the diversity of mammals and birds than groups of the same number of species chosen at random. We show that in order to succeed in representing many mammals and birds in area selection, it is not sufficient for the groups used for selection to occur in many different ecoregions, they must also have low overlaps in distribution, so as to provide high ecological complementarity (a similar pattern of ecological complementarity must be shared by the larger group of species to be represented). Therefore there may be a need for an explicit policy to balance the requirements of flagship conservation and broader biodiversity conservation, which will have implications for the distribution of resources.

“…It covers an area of 825 km 2 that comprises Uganda's largest forest reserve (Howard, 1991). In the reserve, 437 km 2 (53%) is continuous moist semi-deciduous tropical forest and the remainder is grassland communities thought to be capable of supporting forest (Howard et al, 1997). Eggeling (1947) described Budongo as a lowland moist semideciduous forest with varying vegetation characteristics, such as early successional, forests; mixed forest, Cynometra forest, swamp forest, shrubland, and grassland.…”

“…Budongo Forest Reserve is of high importance for global biodiversity, ranking third in overall importance of Ugandan forests (Howard et al, 1997). It contains about 465 species of trees and shrubs (Eggeling, 1947;Howard, 1991).…”

“…Much of this diversity is restricted to 15,000 km 2 of forest reserves (which also contain nonforest habitats) under the jurisdiction of the Uganda Forest Department 13 . The aim of a five-year inventory of the woody plants, large moths (saturnids and sphingids), butterflies, birds, and small mammals (rodents and insectivores) of all of the principal forest reserves was to provide information to the government regarding a plan to protect ϳ3,000 km 2 (20%) of the remaining forest estate as a strict nature reserve 14,15 . Forests were surveyed in proportion to their area (see Methods).…”

using four heat-flux plates and four temperature probes. Evapotranspiration and CO 2 flux were measured using the eddy-covariance method with an Applied Technologies sonic anemometer and LI-COR 6262 infrared gas analyser mounted on 2-m towers 25 . The mean and standard error for energy flux, gross primary production and evapotranspiration at sites 3 and 4 were calculated on the basis of 30-min averages. CO 2 fluxes at sites 11, 17 and 21 were determined using eddycovariance methods and 2.5-m towers 26 . Mean values and standard errors at these sites were calculated using the daily mean CO 2 fluxes. The daily methane fluxes were integrated over the thaw period to obtain annual emission. Winter methane fluxes were assumed to be zero. CH 4 flux was measured during the thaw season, Jun-Aug, at 27 MNT and MAT sites along the Dalton Highway in 1996 using a static chamber method 30 . Air samples were taken over periods of 30-45 min and were analysed on a gas chromatograph equipped with a flame ionization detector.
