The conservation of Earth's forest ecosystems is one of the great environmental challenges facing humanity in the 21st century. All of Earth's ecosystems now face the spectre of the accelerated greenhouse effect and rates of change in climatic regimes that have hitherto been unknown. In addition, multiple use forestry – where forests are managed to provide for both a supply of wood and the conservation of biodiversity – can change the floristic composition and vegetation structure of forests with significant implications for wildlife habitat. Wildlife, fire and future climate: a forest ecosystem analysis explores these themes through a landscape-wide study of refugia and future climate in the tall, wet forests of the Central Highlands of Victoria. It represents a model case study for the kind of integrated investigation needed throughout the world in order to deal with the potential response of terrestrial ecological systems to global change. The analyses presented in this book represent one of the few ecosystem studies ever undertaken that has attempted such a complex synthesis of fire, wildlife, vegetation, and climate. Wildlife, fire and future climate: a forest ecosystem analysis is written by an experienced team of leading world experts in fire ecology, modelling, terrain and climate analysis, vegetation and wildlife habitat. Their collaboration on this book represents a unique and exemplary, multi-disciplinary venture.

Effective Use

Integrating wildlife habitat concerns into multiple-use forest management requires four things: 1) the right attitude, 2) a process for systematic resource coordination, 3) models that relate forest conditions to wildlife outputs, and 4) the effective use of monitoring to support an adaptive management strategy. These four things reflect that resource managers must first want to make forestry-wildlife coordination work, that they need a mechanism for doing it, that they need habitat criteria for meeting wildlife goals, and that we only know enough at this time to get pointed in the right direction.Comprehensive goals for timber and wildlife are set early in successful forestry-wildlife integration. The goals provide for maintaining habitat and wildlife diversity while simultaneously producing consumable surpluses of timber and game in relation to demands for those products. Comprehensive inventories and vegetation growth and yield models are used to analyze the current management situation and show the need for actions to meet goals. The wildlife yield models are species-habitat relationships functions that relate habitat conditions to wildlife outputs by species. The management plan developed constitutes a coordinated set of resource objectives and the schedule of practices that will achieve them in an efficient way. Monitoring the effects of the practices is used to learn whether assumptions and models used in planning need to be revised, and whether the course of management needs to be adjusted to meet the goals. Key words: Forest management, Wildlife management, integration, Wildlife habitat, Multiple use planning.

O objetivo deste estudo foi avaliar alterações florísticas e estruturais ocorridas em áreas de Floresta Ombrófila Densa no Pará, em decorrência das atividades de exploração de impacto reduzido. Para isso, foram utilizadas duas áreas de floresta não manejada (FNM1 e FNM2) e duas de floresta manejada (FM1 e FM2), explorada há quatro anos, com intensidade de corte de 30 m³.ha-1. Utilizou-se amostragem estratificada, com alocação de 24 parcelas de 28 x 350 m, sendo 12 na FM1 e 12 na FNM1, e 20 parcelas de 50 x 200 m, sendo nove na FM2 e 11 na FNM2, mensurando-se todos os indivíduos com DAP ≥ 10 cm. O delineamento foi inteiramente casualizado, com número diferente de repetições. No período de quatro anos após a exploração, ocorreram alterações não significativas na composição florística e abundância de indivíduos, no entanto os índices de Shannon calculados para as áreas diferiram significativamente. A espécie de maior valor de importância na FM1 e FNM1 foi Rinorea guianensis Aubl. e na FM2 e FNM2 foram Licania kunthiana Hook.f. e Richardella macrophylla (Lam.) Aubrév., respectivamente. Após quatro anos da colheita, foram identificadas diferenças significativas apenas no volume total e na dominância absoluta entre FM2 e FNM2.AbstractStructural analysis and multiple use of tree species in managed forest, Middle River Valley of Curuá-una, Pará. This research aimed to evaluate the floristic and structural changes in areas of dense rain forest in Pará, due to the reduced impact logging activities. Inorder to that, two areas of unmanaged forest were used (FNM1 and FNM2), and two of managed forest (FM1 and FM2), explored for four years with intensity of cut 30 m³.ha-1. A stratified sampling was used with allocation of 24 plots of 28 m x 350 m, 12 in the FM1and 12 in the FNM1, and 20 plots of 50 m x 200 m, 9 in the FM2 and 11 in the FNM2, we measured all individuals with DBH ≥ 10 cm. The lineation was completely randomized with different number of repetitions. In the period of four years after forest harvest, non-significant changes occurred in the floristic composition and abundance of individuals, however, the Shannon-Weaver indices calculated for the areas differed significantly. The species with the highest importance value in FM1 and FNM1 was Rinorea guianensis Aubl. and in FM2 and FNM2 were Licania kunthiana Hook.f. and Richardella macrophylla (Lam.) Aubrév., respectively. After four years of harvests, significant differences were found only in total volume and absolute dominance between FM2 and FNM2.Keywords: Phytosociology; Amazon; Forest management.

Abstract We compared four methods of assessing dwarf mistletoe infection and estimating volume of dwarf mistletoe-induced witches' brooms in ponderosa pine (Pinus ponderosa). Witches' brooms can provide important wildlife habitat and can influence fire behavior. We used Hawksworth's dwarf mistletoe rating system (DMR), Tinnin's broom volume rating system (BVR), an estimate of the percentage of live crown occupied by witches' brooms (PCB), and a new system, total broom volume (TBV). We rated 12,536 trees for southwestern dwarf mistletoe (Arceuthobium vaginatum subsp. cryptopodum) infection and broom volume. Using Hawksworth's DMR and Tinnin's BVR systems, we were not able to distinguish trees with different witches' broom volumes at all sample sizes. At all sample sizes, TBV ratings accurately and precisely identified amount of witches' broom volume. We recommend that TBV be used to quantify witches' broom volume in ponderosa pine where wildlife habitat and fire ecology are primary concerns. West. J. Appl. For. 19(1):54–59.

A Value

The ecosystem services model as a valuation tool for cultural capital relies on human well-being as the metric for assigning nature a value that makes sense in a world full of competing choices. If the entire added value of a forest that includes wildlife habitat, recreation, and carbon sequestration is calculated, its continued existence as an intact forest ecosystem can more effectively compete against alternative uses that could either destroy the forest or diminish its services to us. Without a measurable value determined through marginal cost-benefit analysis and the consumer’s willingness to pay, however, the forest ecosystem would be assigned a dollar value of zero, making development the easy default choice. Since outdoor recreation in nature contributes to our well-being, it becomes one of the tools we can use to assign nature value. Responsible travel as ecotourists involves taking visitors into natural areas to educate them about a region’s natural and cultural heritage, as well as to sustain the well-being of local people. Ecotourism can change our relationship with the natural world, as well as teach us how to be better tourists.

Abstract Aims Caryota obtusa of Arecaceae is a fascinating palm tree native to southwestern China, India, Myanmar, Thailand, Laos, and Vietnam. It is an economically important and threatened species and appears as a canopy dominant in some karst areas in Yunnan. We aim to clarify the forest structure, species diversity, population status and regeneration dynamics of C. obtusa in the karst forest ecosystem of Yunnan, China. Methods We established 56 vegetation plots dominated by C. obtusa in 10 counties of southern Yunnan. As based on the plot data, we analyzed the community stratification, floristic composition, and C. obtusa’s population structure. We used questionnaires to interview local people and recorded the human activity history on C. obtusa-dominated forests. Important findings: C. obtusa palm forests were distributed on limestone mountain slopes and gullies. There were seven forest community types. The stratification of each community included arborous layer, shrub layer and understory. The communities had rich species composition. For all the plots as a whole of each community type, Shannon-Wiener diversity index of either woody or herbaceous species ranged from 2.1-3.8. The DBH-class frequency distribution of C. obtusa was a multimodal type. The regeneration was sporadic and depended on intermediate natural disturbances. In current population structure, number of C. obtusa trees with small DBHs was consisted mainly of the forest communities with no or a slight degree of human disturbances. Intensive human activities terribly hindered C. obtusa’s recruitment, followed by medium intensity of human activities.

Abstract This study aims to investigate the spatio-temporal variability and trends in climate and its implications for rainfed agriculture in the Rib watershed, north-western highland Ethiopia from 1986 to 2050. The daily rainfall and temperature records for the period 1986–2017 were used to detect the variability and trends of the current climate using the coefficient of variation, precipitation concentration index, Mann–Kendall test, and Sen's slope estimator. On the other hand, future climate changes (2018–2050) were analyzed based on the Coupled Model Intercomparison Project version 5 (CMIP5) model outputs under under two representative concentration pathway (RCP) scenarios, RCP 4.5 and 8.5. The results showed high inter-seasonal and inter-annual variability of rainfall and temperature in the studied watershed over the last four decades. The annual and Kiremt (June–September) rainfall showed a generally increasing trend, while the Belg (March–May) rainfall exhibited a decreasing trend between 1986 and 2017. Conversely, the minimum, maximum and mean temperature demonstrated increasing trends over the study period although most of the detected trends were statistically insignificant at 5 and 10% level of significance. Future climate analysis results showed an increase in future temperature and annual and Kiremt rainfall while Belg rainfall declined.
