Veblen23 & Rupert Seidl 1 1234567890():,; Increasing evidence indicates that forest disturbances are changing in response to global change, yet local variability in disturbance remains high. We quantified this considerable variability and analyzed whether recent disturbance episodes around the globe were con- sistently driven by climate, and if human influence modulates patterns of forest disturbance. We combined remote sensing data on recent (2001–2014) disturbances with in-depth local information for 50 protected landscapes and their surroundings across the temperate biome. Disturbance patterns are highly variable, and shaped by variation in disturbance agents and traits of prevailing tree species. However, high disturbance activity is consistently linked to warmer and drier than average conditions across the globe. Disturbances in protected areas are smaller and more complex in shape compared to their surroundings affected by human land use. This signal disappears in areas with high recent natural disturbance activity, underlining the potential of climate-mediated disturbance to transform forest landscapes. 1 University of Natural Resources and Life Sciences (BOKU) Vienna, Institute of Silviculture, Peter Jordan Straße 82, 1190 Wien, Austria.

  • Arachnozoogeographical Analysis of the Boundary Between Eastern Palearctic and Indomalayan Region
    Historia naturalis bulgarica, 23: 5-36, 2016 Arachnozoogeographical analysis of the boundary between Eastern Palearctic and Indomalayan Region Petar Beron Abstract: This study aims to test how the distribution of various orders of Arachnida follows the classical subdivision of Asia and where the transitional zone between the Eastern Palearctic (Holarctic Kingdom) and the Indomalayan Region (Paleotropic) is situated. This boundary includes Thar Desert, Karakorum, Himalaya, a band in Central China, the line north of Taiwan and the Ryukyu Islands. The conclusion is that most families of Arachnida (90), excluding most of the representatives of Acari, are common for the Palearctic and Indomalayan Regions. There are no endemic orders or suborders in any of them. Regarding Arach- nida, their distribution does not justify the sharp difference between the two Kingdoms (Paleotropical and Holarctic) in Eastern Eurasia. The transitional zone (Sino-Japanese Realm) of Holt et al. (2013) also does not satisfy the criteria for outlining an area on the same footing as the Palearctic and Indomalayan Realms. Key words: Palearctic, Indomalayan, Arachnozoogeography, Arachnida According to the classical subdivision the region’s high mountains and plateaus.

  • Russia's Boreal Forests
    Forest Area Key Facts & Carbon Emissions Russia’s Boreal Forests from Deforestation Forest location and brief description Russia is home to more than one-fifth of the world’s forest areas (approximately 763.5 million hectares). The Russian landscape is highly diverse, including polar deserts, arctic and sub-arctic tundra, boreal and semi-tundra larch forests, boreal and temperate coniferous forests, temperate broadleaf and mixed forests, forest-steppe and steppe (temperate grasslands, savannahs, and shrub-lands), semi-deserts and deserts. Russian boreal forests (known in Russia as the taiga) represent the largest forested region on Earth (approximately 12 million km2), larger than the Amazon. These forests have relatively few tree species, and are composed mainly of birch, pine, spruce, fir, with some deciduous species. Mixed in among the forests are bogs, fens, marshes, shallow lakes, rivers and wetlands, which hold vast amounts of water. They contain more than 55 per cent of the world’s conifers, and 11 per cent of the world’s biomass. Unique qualities of forest area Russia’s boreal region includes several important Global 200 ecoregions - a science-based global ranking of the Earth’s most biologically outstanding habitats. Among these is the Eastern-Siberian Taiga, which contains the largest expanse of untouched boreal forest in the world. Russia’s largest populations of brown bear, moose, wolf, red fox, reindeer, and wolverine can be found in this region. Bird species include: the Golden eagle, Black- billed capercaillie, Siberian Spruce grouse, Siberian accentor, Great gray owl, and Naumann’s thrush. Russia’s forests are also home to the Siberian tiger and Far Eastern leopard.

  • Grasslands 4/16/03 3:46 PM
    Ecoregion: Grasslands 4/16/03 3:46 PM Grasslands INTRODUCTION About 25% of Earth’s land surface is covered by temperate grassland. These large expanses of flat or hilly country cover much of North America, as well as large areas of Europe, Asia, and South America. Most grasslands are found in the interiors of continents, where there is too little rainfall for a forest but too much rain for a desert. Art Explosion Art Explosion Rolling hills covered with grasses and very few trees A few scattered trees are found on savannas, are typical of North American grassland prairies. tropical grasslands of Africa. Temperate grasslands have subtle differences and different names throughout the world. Prairies and plains of North America are grasslands with tall grasses, while the steppes of Russia are grasslands with short grasses. Veldts are found in South Africa, the puszta in Hungary, and the pampas in Argentina and Uruguay. Savannas are tropical grasslands that support scattered trees and shrubs. They often form a transitional biome file:///Ecoregion/grass/content.html Page 1 of 6 Ecoregion: Grasslands 4/16/03 3:46 PM between deserts and rain forests. Some temperate grasslands are also called savannas. The word savanna comes from the Spanish word zavanna, meaning “treeless plain.” Savannas cover almost half of Africa (mostly central Africa) and large areas of Australia and South America. ABIOTIC DATA The grassland climate is rather dry, averaging about 20 to 100 centimeters (8–40 inches) of precipitation a year. Summers are very hot and may reach 45°C (113°F). Winter temperatures often fall below freezing, which is 0°C (32°F).

  • Forests Warranting Further Consideration As Potential World
    Forest Protected Areas Warranting Further Consideration as Potential WH Forest Sites: Summaries from Various and Thematic Regional Analyses (Compendium produced by Marc Patry, for the proceedings of the 2nd World Heritage Forest meeting, held at Nancy, France, March 11-13, 2005) Four separate initiatives have been carried out in the past 10 years in an effort to help guide the process of identifying and nominating new WH Forest sites. The first, carried out by Thorsell and Sigaty (1997), addresses forests worldwide, and was developed based on the authors’ shared knowledge of protected forests worldwide. The second focuses exclusively on tropical forests and was assembled by the participants at the 1998 WH Forest meeting in Berastagi, Indonesia (CIFOR, 1999). A third initiative consists of potential boreal forest sites developed by the participants to an expert meeting on boreal forests, held in St. Petersberg in 2003. Finally, a fourth, carried out jointly between UNEP and IUCN applied a more systematic approach (IUCN, 2004). Though aiming at narrowing the field of potential candidate sites, these initiatives do not automatically imply that all of the listed forest areas would meet the criteria for inscription on the WH List, and conversely, nor do they imply that any site left off the list would not meet these criteria. Since these lists were developed, several of the proposed sites have been inscribed on the WH List, while others have been the subject of nominations, but were not inscribed, for various reasons. The lists below are reproduced here in an effort to facilitate access to this information and to guide future nomination initiatives.

    Rainforests and Tropical Diversity Gaby Orihuela Visitor Experience Manager Global Strategy for Plant Conservation Objective IV: Education and awareness about plant diversity, its role in sustainable livelihoods and importance to all life on earth is promoted. – Target 14: The importance of plant diversity and the need for its conservation incorporated into communication, education and public awareness programs. What are Rainforests? Forests characterized by high rainfall, with definitions based on a minimum normal annual rainfall of 68–78 inches, and as much as 390 inches. (Miami receives an average annual of ~60 inches.) Two types: Tropical (wet and warm) and Temperate Around 40% to 75% of all biotic species are indigenous to the tropical rainforests Natural reservoir of genetic diversity and ecological services: – Rich source of medicinal plants – High-yield foods and a myriad of other useful forest products – Sustain a large number of diverse and unique indigenous cultures – Important habitat for migratory animals Peruvian Amazonia Where in the World? Today less than 3% of Earth’s land is covered with these forests (about 2 million square miles). A few thousand of years ago they covered 12% (6 million). Tropical forests are restricted to the latitudes 23.5° North and 23.5° South of the equator, or in other words between the Tropic of Capricorn and the Tropic of Cancer.

    Responses of Plant Communities to Grazing in the Southwestern United States Department of Agriculture United States Forest Service Rocky Mountain Research Station Daniel G. Milchunas General Technical Report RMRS-GTR-169 April 2006 Milchunas, Daniel G. 2006. Responses of plant communities to grazing in the southwestern United States. Gen. Tech. Rep. RMRS-GTR-169. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 126 p. Abstract Grazing by wild and domestic mammals can have small to large effects on plant communities, depend- ing on characteristics of the particular community and of the type and intensity of grazing. The broad objective of this report was to extensively review literature on the effects of grazing on 25 plant commu- nities of the southwestern U.S. in terms of plant species composition, aboveground primary productiv- ity, and root and soil attributes. Livestock grazing management and grazing systems are assessed, as are effects of small and large native mammals and feral species, when data are available. Emphasis is placed on the evolutionary history of grazing and productivity of the particular communities as deter- minants of response. After reviewing available studies for each community type, we compare changes in species composition with grazing among community types. Comparisons are also made between southwestern communities with a relatively short history of grazing and communities of the adjacent Great Plains with a long evolutionary history of grazing. Evidence for grazing as a factor in shifts from grasslands to shrublands is considered. An appendix outlines a new community classification system, which is followed in describing grazing impacts in prior sections.

The classifica­ tion system consists of four components (vegetation, soil, landform, and water), a proposed procedure for integrating the components into ecological response units, and a programmed procedure for integrating the ecological response units into ecosystem associations. The classification system described here is the result of literature synthesis and limited field testing and evaluation. It presents one procedure for defining, describing, and displaying ecosystems with respect to geographical distribution. The system and others are undergoing rigorous evaluation to determine the most appropriate procedure for defining and describing ecosystem associations. Bailey, Robert G. 1980.

  • The Riparian Zone
    Land-Water Interactions: The Riparian Zone F J. Swanson, S. V Gregory, J. R. Sedell,and A. G.Campbell INTRODUCTION The interface between aquatic and terrestrial environments in coniferous structure, composition, and function of the riparian zone had received little consideration in ecosystem level research, because this zone forms the interface between scientific disci- plines as well as ecosystem components. In some climate-vegetation zones particular aspects of riparian zones have received much study. ñparinpiant communities in arid lands have been studied extensive!y, primar- ily in terms o TdfeTbiiatJohnson and Jones 1977 Thomas et al 1979) Research on riparian 'egetation along major rivers has dealt mainly with forest composition and dynamics (for example, Lindsey et al. 1961; Sigafoos 1964; Bell 1974; Johnson et al. 1976). Riparian vegetation research has been largely neglected in forested mountain land, where it tends to have smaller areal extent and economic value than upslope vegetation. yre!pian zone is an integral part of the forest/stream ecosystem complex. This chapter synthesizes general concepts about the riparian zone in north- west coniferous forests and the results of coniferous forest biome research on: (1) structure and composition of riparian vegetation and its variation in time and space; and (2) functional aspects of the riparian zone in terms of physical, biological, and chemical terrestrial/aquatic interactions. We emphasize condi- tions observed in mountain streams and small rivers. The riparian zone may be defined in a variety of ways, based on factors such as vegetation type, groundwater and surface water hydrology, topogra- phy, and ecosystem function. These factors have so many complex interactions that defining the riparian zone in one sense integrates elements of the other factors.
