Warming across ice-covered regions will result in changes to both the physical and climatic environment, revealing new ice-free habitat and new climatically suitable habitats for non-native species establishment. Recent studies have independently quantified each of these aspects in Antarctica, where ice-free areas form crucial habitat for the majority of terrestrial biodiversity. Here we synthesise projections of Antarctic ice-free area expansion, recent spatial predictions of non-native species risk, and the frequency of human activities to quantify how these facets of anthropogenic change may interact now and in the future. Under a high-emissions future climate scenario, over a quarter of ice-free area and over 80 % of the ~14 thousand km2 of newly uncovered ice-free area could be vulnerable to invasion by one or more of the modelled non-native species by the end of the century. Ice-free areas identified as vulnerable to non-native species establishment were significantly closer to human activity than unsuitable areas were. Furthermore, almost half of the new vulnerable ice-free area is within 20 km of a site of current human activity. The Antarctic Peninsula, where human activity is heavily concentrated, will be at particular risk. The implications of this for conservation values of Antarctica and the management efforts required to mitigate against it are in need of urgent consideration.

AbstractDowny brome inhibits revegetation efforts following ecosystem disturbance. Imazapic is a commonly used herbicide for downy brome management, but more information is needed regarding effective application timing for restoration efforts. We wished to determine (1) if native species establishment exhibited a tradeoff between downy brome competition and injury from herbicide and (2) if this differed between pre- and postemergent applications of imazapic. We used a standard replacement series design and overlaid herbicide treatments. Nine weeks after planting, aboveground biomass was harvested and relative yield (RY) indices calculated. Both imazapic applications reduced downy brome biomass by 91% or more (P < 0.05). Imazapic caused drastic reductions in native biomass but less than what was caused by downy brome competition (P < 0.05). Natives were less injured by a pre- than postemergent application (P < 0.05). In situations where downy brome may impact restoration efforts, pre-emergent applications of imazapic at 70 g ai ha−1 (0.06 lb ai ac−1) may reduce downy brome with less negative impacts on newly-seeded native grasses than post-emergent applications. Ensuring sufficient proportions of native species seeds on restoration sites may reduce downy brome.

Scenario Approach

This article substantiates the content basis of application of the foresight methodology in the forestry complex in the context of sustainable spatial forestry management. Socio-ecological and economic effectiveness of sustainable forestry is determined by the completeness of continuous and non-exhaustive use of all components of forest ecosystems, including non-market, at all levels of spatial development (local, regional, national and global). It stipulates the high responsibility of the world community, society, state, local authorities and businesses for political, institutional, economic, technological, and project decisions in the sphere of forestry management in the spatial-temporal dimension. It leads to the need for qualitative forecasting of the future sustainable development of the forestry complex, which determines the search and application of modern effective approaches to strategic planning and management of the forestry complex, among which foresight is particularly highlighted. Thus, the paper considers the key features of foresight, which must be taken into account when investigating the future vision of sustainable spatial development of forestry. Thus, the purpose of this study is to generalize and identify the features and possibilities of using the foresight methodology in the forestry complex in the context of sustainable spatial development. The particular features of nature management in the forestry complex in the process of foresight research should be taken into consideration. Existing principles and classification signs for the foresight are presented in the context of sustainable forestry. The application of existing foresight methods is implemented on the example of using the scenario approach to the substantiation of organizational and economic conditions for the formation and development of ecosystem entrepreneurship. At the same time, we have considered the application of the scenario approach within the framework of solving the problem of forest ecosystem business development. The development of entrepreneurship on the ecological and economic basis should become a qualitatively new and effective type of forestry management based on the use of advanced, innovative methods, forms, methods of production organization and combination of resources. The variable development of the use of the scenario approach to the substantiation of organizational and economic conditions for the formation and development of forest ecosystem entrepreneurship has been presented. Thus, the use of various foresight technologies (in particular, the scenario approach) will provide a qualitatively new level of constructive substantiation, in particular, the national strategy for sustainable forestry and long-term forestry programs on an innovative basis.

AbstractThe small ice-free areas of Antarctica provide an essential habitat for most evident terrestrial biodiversity, as well as being disproportionately targeted by human activity. Visual detection of disturbance within these environments has become a useful tool for measuring areas affected by human impact, but questions remain as to what environmental consequences such disturbance actually has. To answer such questions, several factors must be considered, including the climate and biotic and abiotic characteristics. Although a body of research has established the consequences of disturbance at given locations, this paper was conceived in order to assess whether their findings could be generalized as a statement across the Antarctic continent. From a review of 31 studies within the Maritime Antarctic, Continental Antarctic and McMurdo Dry Valleys regions, we found that 83% confirmed impacts in areas of visible disturbance. Disturbance was found to modify the physical environment, consequently reducing habitat suitability as well as directly damaging biota. Visible disturbance was also associated with hydrocarbon and heavy metal contamination and non-native species establishment, reflecting the pressures from human activity in these sites. The results add significance to existing footprint measurements based on visual analysis, should aid on-the-ground appreciation of probable impacts in sites of disturbance and benefit environmental assessment processes.

Establishment and spread of non-native species following wildfires can pose threats to long-term native plant recovery. Factors such as disturbance severity, resource availability, and propagule pressure may influence where non-native species establish in burned areas. In addition, pre- and post-fire management activities may influence the likelihood of non-native species establishment. In the present study we examine the establishment of non-native species after wildfires in relation to native species richness, fire severity, dominant native plant cover, resource availability, and pre- and post-fire management actions (fuel treatments and post-fire rehabilitation treatments). We used an information-theoretic approach to compare alternative hypotheses. We analysed post-fire effects at multiple scales at three wildfires in Colorado and New Mexico. For large and small spatial scales at all fires, fire severity was the most consistent predictor of non-native species cover. Non-native species cover was also correlated with high native species richness, low native dominant species cover, and high seeded grass cover. There was a positive, but non-significant, association of non-native species with fuel-treated areas at one wildfire. While there may be some potential for fuels treatments to promote non-native species establishment, wildfire and post-fire seeding treatments seem to have a larger impact on non-native species.
