Like other bird and mammal species whose populations have been restored through conservation efforts, wild turkeys are treasured by many recreationists and outdoor enthusiasts. Wild turkeys have responded positively to wildlife habitat and population management. In some areas, however, their increased populations have led to increased damage to property and agricultural crops, and threats to human health and safety. Turkeys frequent agricultural fields, pastures, vineyards and orchards, as well as some urban and suburban neighborhoods. Because of this, they may cause damage or mistakenly be blamed for damage. Research has found that despite increases in turkey numbers and complaints, damage is often caused by other mammalian or bird species, not turkeys. In the instances where turkeys did cause damage, it was to specialty crops, vineyards, orchards, hay bales or silage pits during the winter. In cultured crops or gardens where wood chips, pine straw or other bedding materials (mulch) are placed around plants, wild turkeys sometimes scratch or dig up the material and damage plants when searching for food. Wild turkeys are a valuable game species, treasured by recreational hunters and wildlife enthusiasts.

Abstract The development of high way that crosses wildlife habitat will inevitably cause wildlife casualties. The purpose of this study was to identify wildlife road mortality in Rawa Aopa Watumohai National Park, Southeast Sulawesi (mostly consisted of savanna). Road kill data was collected by driving along the 22.4 km highway in February and March 2020 (n=28). Traffic volumes were recorded by taking traffic samples in 5 different times of the day, an hour duration each (totaling 70 h). There were 37 species being killed (totaling 529 individuals, of which 49.3% happened along km 0-10), consisted of 19 bird species, 3 small mammal species, 10 reptile species, and 5 amphibian species. Based on taxa, the highest number of road mortality was amphibians (dominated by Ingerophrynus biporcatus), followed by birds (mostly Lonchura malacca), mammals (dominated by Rattus argentiventer), and reptiles (dominated by Varanus salvator). Among mammals, no big mammal (booted macaque Macaca ochreata, wild boar Sus scrofa) was killed. Landscape transformation clearly has impacted wildlife in the study area. To reduce the occurrence of road kills, it is recommended to create corridors for wildlife crossings, limiting vehicle speed in the hot spots locations, create speed bumps, as well as adding more signage and road signs along the highway.

Wildlife assessments can provide crucial information regarding species richness, relative abundance and spatial, temporal, and ecological information on wildlife habitat associations. The assessment’s information can in turn be used for developing management policies including for establishing touristic zones. We investigated wildlife occurrences in the Chandragiri Hills, Kathmandu Nepal from 2015-2019 to provide baseline data to inform the potential sites for ecotourism. During the study period, we recorded 30 mammal species, 199 bird species, 34 herpetofauna species and 77 butterfly species. The area harbors three globally and six nationally threatened mammal species, two globally and seven nationally threatened with one endemic bird species, one globally and nationally threatened herpetofauna, and one nationally threatened butterfly species. We also explored four potential hiking routes for observing wildlife and providing scenic views of the Himalayan range and Kathmandu city. Therefore, we expect Chandragiri Hills can become one of the hot spot for tourists to observe both common and threatened wildlife species in Nepal.

European Settlement

Sixteen mammal species and 22 bird species whose distributions extended into southwestern Australian forests before European settlement have been listed as threatened at some time in Commonwealth legislation, State legislation, or action plans of Environment Australia or its predecessors. Confident assessment of the causes of conservation status is hampered by poor base-line data, few studies of putative impacts and a preponderance of circumstantial or anecdotal rather than experimental evidence. However, introduced foxes were Implicated In the current conservation status of 62% of the mammal species recognized, while 44% of them were negatively impacted by feral cats, 44% by agricultural clearing and 44% by changed fire regimes. Forestry practices were impllcated in the conservation status of only one mammal species. For the bird species recognized, changed fire regimes had the greatest negative impact (45% affected), agricultural clearing affected 41%, draining of wetlands affected 32% and grazing by livestock affected 22%. Forestry practices were not directly implicated in the conservation status of any bird species. While these results suggest that forestry has had minimal direct impact on the mammals and birds of the forests, the conclusion should be treated cautiously because of the poor data. While awaiting a rigorous evaluation, we argue for a strong precautionary approach to forestry in the region. With proper forest management and sound sylvicultural [sic] treatment there is no reason why there should not be built up on the wreckage of the once splendid forests of Western Australia tended forests which will yield for all time 100 cubic feet of timber per acre per year. Lane-Poole (1920). There are many reasons why Australian environmentalists would like to end logging in native forests. The preservation of wilderness, aesthetics, an almost religious identification with old growth forests and the conservation of forest wildlife figure importantly in environmental efforts to restrict logging. Wilderness and a personal identification with trees and undisturbed forests are fundamentally incompatible with logging. Recher (1996).

Production Forests

In Tasmania, a system of 100 m wide strips of native forest, referred to as wildlife habitat strips, is retained within production forest, including plantations. Thirty-nine points in 18 wildlife habitat strips within both eucalypt and pine plantations (which were not differentiated for the purposes of the present study) were paired with points in nearby extensive native forest and surveyed for birds. At non-riparian sites (upper slopes and ridges), bird species richness and total abundance were both significantly lower in habitat strips than in controls. This difference is quantitative rather than qualitative, as ordination did not distinguish strip sites and controls, and no species were obviously absent from habitat strips. Riparian zones showed no significant difference in species richness and total abundance between habitat strips and controls. Species richness and total abundance relative to controls increased as wildlife habitat strip length increased over the measured range (0.4-2.1 km). It is thought that this may be because birds perceive strips as linear forest patches rather than corridors, so that there may be a habitat area effect. Other strip characteristics such as width and plantation age were not significant in riparian areas, but may be important on upper slopes and ridges, and the former will affect strip area. Wildlife habitat strips appear to be a valuable component of a conservation programme for birds in production forests in Tasmania.

A survey of mammals and birds was carried out in a semi-deciduous forest fragment of 150 ha located in a zone of intensive agriculture in Ribeirão Preto, State of São Paulo, south-eastern Brazil. Line transect sampling was used to census mammals and birds during six days, totalling 27.8 km of trails and 27.8 hours of observation. Twenty mammal species were confirmed in the area (except bats and small mammals), including rare or endangered species, such as the mountain lion (Puma concolor), the maned wolf (Chrysocyon brachyurus), and the ocelot (Leopardus pardalis). The brown capuchin monkey (Cebus apella) and the black-tufted-ear marmoset (Callithrix penicillata) were found frequently, suggesting high population density in the fragment. Regarding the avifauna, 49 bird species were recorded, most of them typical of open areas or forest edges. Some confirmed species, however, are becoming increasingly rare in the region, as for example the muscovy duck (Cairina moschata) and the toco toucan (Ramphastos toco). The results demonstrate that forest fragment of this size are refuges for native fauna in a region dominated almost exclusively by sugar-cane plantations. Besides faunal aspects, the conservation of these fragments is of great importance for the establishment of studies related to species preservation in the long term, including reintroduction and translocation projects, as well as studies related to genetic health of isolated populations.

Significant Difference

Particle size reduction is a primary means of improving efficiency in herbivores. The mode of food particle size reduction is one of the main differences between herbivorous birds (gizzard) and mammals (teeth). For a quantitative comparison of the efficiency of food comminution, we investigated mean fecal particle sizes (MPS) in 14 herbivorous bird species and compared these with a data set of 111 non-ruminant herbivorous mammal species. In general MPS increased with body mass, but there was no significant difference between birds and mammals, suggesting a comparable efficiency of food processing by gizzards and chewing teeth. The results lead to the intriguing question of why gizzard systems have evolved comparatively rarely among amniote herbivores. Advantages linked to one of the two food comminution systems must, however, be sought in different effects other than size reduction itself. In paleoecological scenarios, the evolution of “dental batteries,” for example in ornithopod dinosaurs, should be considered an advantage compared to absence of mastication, but not compared to gizzard-based herbivory.

Clearcut Logging

Protocols to select ecological indicators of sustainable forest management will benefit from a proactive approach that identifies species likely to be most seriously impacted by management. Here, we use an objective approach that couples forest resource inventory information from logged and unlogged landscapes in northeastern Ontario with information from the provincial vertebrate habitat suitability matrix to assess habitat suitability (the amount of used and preferred habitats) in the landscapes and to identify potential indicators of the impacts of forest management activities. Because they may be most representative of potential future logged landscapes in the region, we contrasted the oldest post-clearcut landscapes in the region (1950s and 1960s era, n = 27) with unlogged landscapes (n = 16). Each landscape was a 2-km radius circle (12.6 km2). In light of reported invasions of hardwood species into logged conifer sites, we considered two regeneration scenarios for very young post-harvest stands: full and partial regeneration control. Logged landscapes differed markedly from unlogged landscapes with respect to forest age and forest type. These differences resulted in strong distinctions between logged and unlogged forests for bird and mammal communities, but relatively weak separation for herpetofauna. Redundancy analysis indicated that the percent variation in habitat suitability attributable to logging was 27% for birds, 17–18% for mammals, and 8–12% for herpetofauna. More than 40% of bird and mammal species showed highly significant differences in habitat suitability between the two landscape types (P<0.01), with more species having higher suitability in unlogged than logged forests. This higher habitat suitability in unlogged forests was associated with a greater amount of older forests and a higher richness of forest types in unlogged compared to logged forests. The effect of the two regeneration scenarios was discernible for all communities, but had a relatively weak effect, with the possible exception of higher snowshoe hare (Lepus americana) densities under partial compared to full regeneration control. Various lines of evidence are presented suggesting that these differences between logged and unlogged landscapes may be maintained into the future unless actions are taken to ameliorate these effects of clearcut logging. The technique presented here may prove useful in forest monitoring and adaptive management planning because it is objective, can simultaneously consider a large number of forest taxa, focuses on real rather than projected landscapes, and outlines, in a succinct way, the main habitat-related gradients in habitat suitability matrices. Key words: wildlife habitat supply, clearcut logging, boreal forest, indicator species, forest age, forest regeneration, multivariate analysis

V prispevku je podan pregled trenutnega poznavanja favne kopenskih habitatov Pivških jezer. Doslej je bilo na območju ugotovljenih 20 vrst sesalcev in 127 vrst ptic. Od ptic jih 75 vrst tu tudi gnezdi. Izpostavljene so vrst evropske ohranitvene pozornosti kot so kosec, hribski škrjanec, podhujka in pisana penica. Pisana penica, poljski škrjanec, rjavi srakoper in velik strnad imajo na Pivških jezerih ene največjih gnezditvenih gostot v državi. Na območju Pivških jezer je bilo doslej ugotovljenih 8 vrst plazilcev in 9 vrst dvoživk. Večina vrst je uvrščena na rdeči seznam ogroženih živali. Metulji dnevniki so relativno dobro raziskani. Za območje je znanih 106 vrst kar znaša 57% vseh v Sloveniji živečih vrst metuljev. Tudi med metulji je veliko ogroženih in ranljivih vrst. Doslej je znanih prek 210 vrst hroščev. Ocenjeno je, da tu živi med 4000 do 6000 vrst hroščev. Veliko ogroženih vrst je vezanih na močvirne travnike jezer, suha kraška travišča ter kamnite griže. Za gozdove in grmišča je značilnih manj ogroženih vrst živali. Naravovarstveno so pomembni ostanki starih hrastovih gozdov. Na območju Pivških jezer je zaradi opuščanja človekove rabe opaziti hitro zaraščanje travišč, kar vodi v zmanjševanje biotske pestrosti. Poleg pravnega zavarovanja Pivških jezer je zato predlagano aktivno upravljanje, ohranjanje in usmerjanje ter spodbujanje dosedanje ekstenzivne kmetijske rabe.  The paper gives an overview of the current knowledge of the fauna of the land habitats around the Pivka lakes. So far 20 mammal species and 127 bird species have been identified. Of the bird species, 75 also nest here. Special attention is paid to European conservation species such as the corn crake, woodlark, nightjar and barred warbler. The nesting density of the barred warbler, skylark, red-backed shrike and corn bunting at the Pivka lakes is among the highest in the country. In the area of the Pivka lakes 8 reptile species and 9 amphibian species have been identified. The majority of these species are on the Red List of Threatened Animals. The butterflies have been relatively well researched. 106 species have been identified in the area, which amounts to 57% of all species of butterflies living in Slovenia. Many of them are threatened and vulnerable species. To the present, 210 species of beetles have been identified, live here. Many of the threatened species are connected with the marshy grasslands of the lakes, dry karst grasslands and barren rocky outcrops. There are fewer threatened animal species in the forests and brush. The remains of old oak forests are scientifically important. Due to the abandonment of land use by humans in the area of the Pivka lakes we can observe the rapid overgrowth of pasturelands, which leads to decreased biodiversity. In addition to legal protection of the Pivka lakes it is therefore also recommend active management and conservation as well as preserving and encouragement of the formerly extensive farming practices.

Birds and mammals were censused in a ribbon of remnant vegetation along a stream connecting two rainforest fragments on a farm on the Atherton Tablelands of North Queensland. The vegetation consisted of two larger (6.5 and 19.6 ha) and one smaller forest remnant (1.1 ha) and numerous tiny disconnected patches scattered across the property and along the creek. These were classified into five types ? "Forest", "Regeneration", "Copse", "Lantana" and "Tobacco Bush". Censuses were also done in four windbreak plantings. Sixty-four species of birds were recorded in systematic censuses in the patches along the creek and in the windbreaks. Along the creek, "Forest" patches had the most species and the most rainforest species followed by "Copse" and "Regeneration" sites. "Lantana" patches were surprisingly rich in species; a total of 32 were recorded including nine rainforest species. The fewest bird species were recorded in the windbreaks which were particularly poor in rainforest species. Small mammals were live trapped in the three larger patches, in the ribbon and in one windbreak. Eleven species were captured ? six rainforest, three grassland and two introduced. The grassland species were not caught in the larger forest patches and two rainforest rodents were not caught along the creek. Nothing was caught in the windbreak but grassland species were caught in an adjoining abandoned orchard. Three species of arboreal mammals were recorded by spotlighting ? Lumholtz' Tree-kangaroo Dendrolagus lumholtzi, Coppery Brushtail Possum Trichosurus vulpecula johnstonii and Green Ringtail Possum Pseudocheirus archeri. All occurred in the stream vegetation as well as the larger forest patches. None were seen in any of the four windbreaks. It is concluded that the creek vegetation is valuable wildlife habitat. The windbreaks were less so but were still useful to the fauna on the study area.

Vu Quang Nature Reserve, Vietnam, was brought to the attention of the world scientific community following the discovery of two previously undescribed large mammal species in the early 1990s. In light of the identification of other sites of high biodiversity value in the Annamite mountains of Vietnam and Laos, the relative importance for biodiversity conservation of Vu Quang needs to be reassessed. In this paper we evaluate the importance of the site for bird conservation, in relation to 13 other protected areas in the Annamese Lowlands Endemic Bird Area (EBA) and present species lists for all 14 sites. Whilst Vu Quang supports one of the highest numbers of recorded bird species of all 14 protected areas, a complementarity analysis revealed that Vu Quang does not fall within the critical subset of sites necessary to conserve 95% of the avifaunal diversity of the EBA. The site should not, therefore, be considered a regional bird conservation priority. Furthermore, of the nine restricted-range species known from the Annamese Lowlands EBA, only three are known from Vu Quang, which is not, therefore, a priority site for the conservation of endemic bird species. We also evaluate the conservation status of the avifauna of Vu Quang, and propose potential conservation measures to enhance its importance for bird conservation.
