Climate-induced shifts in grassland bird nesting phenology have implications for grassland management

Grasslands are among the most impacted ecosystems globally. In the midcontinent of North America, a > 80% loss of grasslands has made their conservation a major priority for resource managers. Grassland ecosystems evolved under periodic disturbances; consequently, grassland management often involves regular actions such as grazing, haying, or burning to maintain ecosystem integrity. The timing of such practices has direct implications on grassland ecology, agricultural economics, and survival and fecundity of grassland nesting birds (hereafter grassland birds). We conducted a meta-analysis on the nesting phenology of grassland birds throughout North America, focusing on nest-survival literature. We constructed a well-fitting model to predict median date of expected nest departure (hereafter fledge date) for grassland birds across the midcontinent. Predictions from our model demonstrate considerable spatial variation in median nesting phenology that is predictable using a spatially explicit spring phenology index. Median fledge dates were 8 or 13 days earlier in years of extreme weather conditions (dry or wet, respectively) than in years of average conditions. Species that generally nest in taller vegetation tended to have later median nest phenologies than those using shorter vegetation. Our results incorporate the most rigorous information available in the literature on nesting phenology of 36 grassland bird species and improve information available to managers about nesting phenology of grassland birds in the midcontinent of North America. Our predictions approximate the day when one-half of the nesting efforts would be complete for a given area within the midcontinent grasslands and can inform management and conservation decisions about the timing of management actions in grassland ecosystems.

The Impact of the Covid-19 Pandemic on Human Resource Management Priorities

Abstract The pandemic situation associated with the Covid-19 disease has changed people's lives and significantly affected the functioning of companies and organizations. Managers of industrial companies faced a new situation and had to look for new solutions to the problems that arose. Employees were forced to get used to new conditions and adapt not only to new private along with new work situations caused by the pandemic. The success of any organization depends on its employees, which is why a high-quality human resource management was important also in the pandemic situation. The aim of the article is to interpret the results of research aimed at identifying priorities in the field of human resource management in terms of the situation before and during the pandemic as well as the priorities that will dominate after the return to the standard work regime. The collection tool was a questionnaire distributed online. As many as 70 managers and specialists from industrial companies in Slovakia took part in the questionnaire survey. The obtained data were evaluated through descriptive statistics, in the form of graphs and tables. The results can be useful for practice of industrial companies in the field of setting priorities, or evaluating and comparing the situation in the field of human resource management before and during the pandemic as well as after the return to the standard work regime.

Defining Cultural Resources: A Case Study from the Mid-Atlantic United States

Integrating cultural and natural resources for large landscape conservation remains an applied challenge for landscape planners and resource managers across North America. When resources are considered at a regional scale, developing shared priorities, definitions, and metrics is an essential but complex process for successful conservation partnerships. Strategies exist for designing regional conservation models for natural resources, but methods for cultural resource conservation planning often remain focused on individual sites and buildings. Here, we build on our previous work with the Landscape Conservation Cooperatives to advance frameworks and spatial models for regionally integrated natural and cultural resource conservation design and planning. Specifically, we present the results of our survey of cultural resource specialists in the Mid-Atlantic region of the United States to better understand how cultural resources are defined, classified, and valued by this group. Methods from applied cognitive anthropology are useful for uncovering cultural consensus and more marginalized perspectives around resource management priorities, offering a clear pathway for integrating cultural and natural resource conservation. We conclude by restating a call for a National GAP-like research program for cultural resources that integrates diverse cultural practices, perspectives, histories, and values of communities for designing future conservation priorities.

Distribution of trespass cannabis cultivation and its risk to sensitive forest predators in California and Southern Oregon.

Illegal cannabis cultivation on public lands has emerged as a major threat to wildlife in California and southern Oregon due to the rampant use of pesticides, habitat destruction, and water diversions associated with trespass grow sites. The spatial distribution of cultivation sites, and the factors influencing where they are placed, remain largely unknown due to covert siting practices and limited surveillance funding. We obtained cannabis grow-site locality data from law enforcement agencies and used them to model the potential distribution of cultivation sites in forested regions of California and southern Oregon using maximum entropy (MaxEnt) methods. We mapped the likely distribution of trespass cannabis cultivation sites and identified environmental variables influencing where growers establish their plots to better understand the cumulative impacts of trespass cannabis cultivation on wildlife. We overlaid the resulting grow-site risk maps with habitat distribution maps for three forest species of conservation concern: Pacific fisher (Pekania pennanti), Humboldt marten (Martes caurina humboldtensis), and northern spotted owl (Strix occidentalis caurina). Results indicate that cannabis cultivation is fairly predictably distributed on public lands in low to mid-elevation (~800-1600m) forests and on moderate slopes (~30-60%). Somewhat paradoxically, results also suggest that growers either preferred sites inside of recently disturbed vegetation (especially those burned 8-12 years prior to cultivation) or well outside (>500m) of recent disturbance, perhaps indicating avoidance of open edges. We ground-truthed the model by surveying randomly selected stream courses for cultivation site presence in subsets of the modeling region and found previously undiscovered sites mostly within areas with predicted high likelihood of grow-site occurrence. Moderate to high-likelihood areas of trespass cultivation overlapped with 40 to 48% of modeled habitats of the three sensitive species. For the endangered southern Sierra Nevada fisher population, moderate-high likelihood growing areas overlapped with over 37% of modeled fisher denning habitat and with 100% of annual female fisher home ranges (mean overlap = 48.0% + 27.0 SD; n = 134) in two intensively studied populations on the Sierra National Forest. Locating and reclaiming contaminated cannabis grow sites by removing all environmental contaminants should be a high priority for resource managers.

Monitoring organic-matter decomposition and environmental drivers in restored vernal pools

Vernal pools are small, shallow and ephemeral freshwater wetlands, often located in forests. Despite harboring high levels of biodiversity and being biochemical hotspots, they have been severely degraded by human activities. Restoration of vernal pools has become a priority for resource managers, and monitoring of restoration projects is needed to track the effectiveness of restoration techniques. In this study, we analyzed the ecological functioning of natural and restored vernal pools in the forest of Chinon (France) four years after a restoration project. Specific aims were to: (1) compare organic-matter decomposition rates between natural and restored pools, and (2) evaluate the main drivers of organic-matter decomposition in these two types of pool. In five natural and nine restored vernal pools, a standardized organic-matter decomposition assay (cotton strip) was deployed for up to 57 days. Each pool was characterised in terms of vegetation type, water and soil quality. We found that decomposition rates did not differ between natural and restored pools. The natural pools, however, had the greater stores of total organic carbon (TOC) content, and Sphagnum moss cover. Across both pool types, decomposition rates were positively associated with canopy openness and vascular plant cover, suggesting a possible ‘priming effect’ of primary producers on microbial decomposers. Sphagnum moss cover and some soil variables, such as TOC, were associated with slowed decomposition, highlighting the potential of Sphagnum spp. at influencing microbial activity. We suggest that future studies couple the cotton strip assay with biotic indices to assess the overall functioning of these wetlands.

The Marine Plan Partnership: Indigenous community-based marine spatial planning

Marine spatial planning (MSP) is occurring throughout the world, as communities and nation-states seek to resolve spatial conflicts and competition in coastal areas and reduce the impacts of human uses on marine biodiversity. The Marine Plan Partnership (MaPP) in British Columbia, Canada, is a successful example of collaborative marine planning between First Nations governments and the British Columbia provincial government, achieving the protection of ecological and cultural values, while supporting sustainable economic activities. The collaborative planning process was pre-dated by territorial marine planning by each participating First Nation, which allowed for the protection of First Nations governance and economy, cultural values and activities, and resource management priorities.

Mapping Presence and Predicting Phenological Status of Invasive Buffelgrass in Southern Arizona Using MODIS, Climate and Citizen Science Observation Data

The increasing spread and abundance of an invasive perennial grass, buffelgrass (Pennisetum ciliare), represents a critical threat to the native vegetation communities of the Sonoran desert in southern Arizona, USA, where buffelgrass eradication is a high priority for resource managers. Herbicidal treatment of buffelgrass is most effective when the vegetation is actively growing, but the remoteness of infestations and the erratic timing and length of the species’ growth periods confound effective treatment. The goal of our research is to promote buffelgrass management by using remote sensing data to detect where the invasive plants are located and when they are photosynthetically active. We integrated citizen scientist observations of buffelgrass phenology in the Tucson, Arizona area with PRISM precipitation data, eight-day composites of 250-m Moderate-resolution Imaging Spectroradiometer (MODIS) satellite imagery, and aerially-mapped polygons of buffelgrass presence to understand dynamics and relationships between precipitation and the timing and amount of buffelgrass greenness from 2011 to 2013. Our results show that buffelgrass responds quickly to antecedent rainfall: in pixels containing buffelgrass, higher correlations (R2 > 0.5) typically occur after two cumulative eight-day periods of rain, whereas in pixels dominated by native vegetation, four prior 8-day periods are required to reach that threshold. Using the new suite of phenometrics introduced here—Climate Landscape Response metrics—we accurately predicted the location of 49% to 55% of buffelgrass patches in Saguaro National Park. These metrics and the suggested guidelines for their use can be employed by resource managers to treat buffelgrass during optimal time periods.

Quantifying the domestic market in herbal medicine in Benin, West Africa

Ethnopharmacological relevanceHerbal medicine markets are essential in understanding the importance of medicinal plants amongst a country's inhabitants. They are also instrumental in identifying plant species with resource management priorities. To document the diversity of the medicinal plant market in Benin (West Africa), to quantify the weight of traded species in order to evaluate their economic value, and to make a first assessment of their vulnerability for commercial extraction. Materials and methodsWe quantitatively surveyed 22 market stalls of 16 markets in the country's eight largest urban areas. We collected all plant (parts) following standard botanical methods and recorded uses, prices and local names, and weighed and counted the numbers of sales units. ResultsWe recorded 307 medicinal products corresponding to ca. 283 species. Thirty-five species were encountered in at least 25% of the surveyed stalls, from which ten are locally endangered or red-listed by the IUCN. Examples of vulnerable species included Caesalpinia bonduc, which has been declared extinct in the wild but is largely cultivated in home gardens, and was exploited for its seeds, roots, and leaves, and Zanthoxylum zanthoxyloides which was harvested for its bark, roots, and leaves. Other top-selling fruits and seeds included red-listed species: Monodora myristica, Xylopia aethiopica, and Schrebera arborea. Top-selling woody plant parts included the roots of Sarcocephalus latifolius, Mondia whitei, and the barks of Khaya senegalensis and Pteleopsis suberosa. All but Sarcocephalus latifolius and Pteleopsis subersosa were species with some threat status. Plants sold at the market were mainly used for ritual purposes, women's health, and to treat malaria and its symptoms. ConclusionOur results suggest that the domestic medicinal plant market in Benin is of substantial economic importance. A volume of approximately 655 metric tons worth 2.7 million USD is offered for sale annually. Traditional spiritual beliefs seem to be a major driving force behind the trade in herbal medicine.

Planning for climate change across the US Great Plains: concerns and insights from government decision-makers

While both international and national efforts are being made to assess climate change and mitigate effects, primary impacts will likely be regional. The US Great Plains region is home to a mosaic of unique ecosystems which are at risk from climate change. An exploratory survey of over 900 Great Plains government officials shows concerns for specific natural resources but not global climate change. Local government decision-makers are important sources of initiation for environmental policy; however, less than 20 % of jurisdictions surveyed have developed plans for adapting to or mitigating potential climate change impacts. The continental extremes of seasonal and annual climate variability of the Great Plains can mask the effects of global climate change and likely influences its’ residents lack of concern. The study findings indicate a need to reframe the discussion away from climate change skepticism, toward a focus on possible impacts within current resource management priorities such as drought, so that proactive planning can be addressed.

Modelling invasion for a habitat generalist and a specialist plant species

ABSTRACTPredicting suitable habitat and the potential distribution of invasive species is a high priority for resource managers and systems ecologists. Most models are designed to identify habitat characteristics that define the ecological niche of a species with little consideration to individual species’ traits. We tested five commonly used modelling methods on two invasive plant species, the habitat generalist Bromus tectorum and habitat specialist Tamarix chinensis, to compare model performances, evaluate predictability, and relate results to distribution traits associated with each species. Most of the tested models performed similarly for each species; however, the generalist species proved to be more difficult to predict than the specialist species. The highest area under the receiver‐operating characteristic curve values with independent validation data sets of B. tectorum and T. chinensis was 0.503 and 0.885, respectively. Similarly, a confusion matrix for B. tectorum had the highest overall accuracy of 55%, while the overall accuracy for T. chinensis was 85%. Models for the generalist species had varying performances, poor evaluations, and inconsistent results. This may be a result of a generalist's capability to persist in a wide range of environmental conditions that are not easily defined by the data, independent variables or model design. Models for the specialist species had consistently strong performances, high evaluations, and similar results among different model applications. This is likely a consequence of the specialist's requirement for explicit environmental resources and ecological barriers that are easily defined by predictive models. Although defining new invaders as generalist or specialist species can be challenging, model performances and evaluations may provide valuable information on a species’ potential invasiveness.

“I’m not a greenie but…”: Environmentality, eco-populism and governance in New Zealand Experiences from the Southland whitebait fishery

The experiences of nascent local institutions in regional resource management issues in New Zealand can help to inform the important analytical projects of considering the impacts of neoliberalism on environmental management as well as the meanings of governance as the new order in rural and natural resource management. This study considers how devolved governance shapes individual subject positions relative to the environment in a neoliberal context, deploying Agrawal's optics of “environmentality” to analyze a case study of the political ecology of the whitebait fishery in Southland, New Zealand. This research demonstrates that the devolution of resource governance in New Zealand has cultivated empowered, ‘accidental environmentalists’ and related environmental subjectivities. The extent and quality of individual involvement in governance influences whitebaiters’ perceptions of environmental change and resource management priorities. At the same time, a strong ‘eco-populist’ conceptualization of resource management infuses the fishers’ environmental subjectivities and potentially constrains the depth and degree of fishers’ opposition to environmental degradation.

Local cultural knowledge and water resource management: the Wind River Indian Reservation.

Ecology and culture comprise interacting components of landscapes. Understanding the integrative nature of the landscape is essential to establish methods for sustainable management. This research takes as a unifying theme the idea that ecological and cultural issues can be incorporated through management. As a first step in developing integrative management strategies, information must be collected that compares and contrasts ecological and cultural issues to identify their areas of intersection. Specifically how can local cultural knowledge enable water resource management that reflects cultural and ecological values? This research examines Native American cultural knowledge for setting water resource management priorities in the Wind River Indian Reservation in central Wyoming. A cross-cultural approach is adopted to assess the relationship between indigenous cultural knowledge and Euro-American perspectives through a comparative examination of the Wind River Water Code and Wyoming Water Law. This research indicates that cultural perspectives provide a rich arena in which to examine management issues. Understanding and identifying cultural practices may be an important first step in collaborative resource management between different cultural groups to prevent conflict and lengthy resolution in court.

Native Peoples and the Management of Natural Resources in the Pacific Northwest: A Comparative Assessment

A cornerstone of the Pacific Northwest's economy has been the development of natural resources. At the same time, the management of the region's resources is shrouded in endless controversy. As such controversy rages, the position of native peoples on both sides of the Canada-United States border is often overlooked. As one native government official observed emphatically, Absolutely, there is a much bigger, growing role for tribal governments in managing natural resources.' Such is evident in a number of ways. In British Columbia, the Nisga'a land claims settlement and the recognition of native ownership have established a provincewide precedent for native peoples as active participants in resource management policymaking. In the U.S., tribal governments have become primary actors in attempts to restore the region's troubled salmon fishery and have assumed greater responsibility for management of forest and water resources. This article explores native management of natural resources in a comparative Canada-U.S. context. Its first section focuses on the Pacific Northwest and examines the role of native peoples in four areas--forestry, watershed management, fisheries, and endangered species protection. The second part assesses the evolving relationship between native and subnational government actors and provides a partial answer to several important questions: What values and goals do native peoples add to the mix of issues, ideas, and interests currently shaping natural resource policy in the Pacific Northwest? What are the implications for provincial, state, and federal policymakers? Will it add complexity to an already fractious process, or help move the current debate in new directions? Although native peoples have a long history of managing the natural environment, they have been marginalized by a natural resource policy process guided by utilitarian values and controlled by governments and extractive industries. They have, therefore, often been spectators in the development of the natural resources central to their subsistence and cultural heritage. Beginning in the 1960s, the Canadian and U.S. governments, acknowledging that native peoples were often the poorest of their citizens, sought to promote economic independence and encouraged tribal governments to seek political and legal confirmation of claims to historic lands and resources. (2) In pursuit of these claims, native peoples in both countries have had their greatest success in the court systems, where numerous decisions have confirmed ownership of historic lands, awarded a share of natural resources, and established the need to consult native peoples when determining natural resource management priorities. For example, federal cour ts in the U.S. have determined native tribes in the Pacific Northwest are entitled to a fair share (50 percent) of fisheries resources and that states have only a limited power to regulate treaty Indian fisheries. (3) Further, U.S. courts have ruled tribes in Idaho (Lake Coeur d' Alene) and Montana (Flathead Lake) hold title to significant portions of major lakes. (4) In Canada, the Supreme Court has established the existence of aboriginal title in British Columbia and determined that such title extended to traditional tribal lands. (5) The Supreme Court of Canada and the U.S. Supreme Court have also recognized the right of native peoples to be consulted on actions and policies that affect the use and management of natural resources. The Canadian Supreme Court ruled in Delgamuukw that the federal and provincial governments have a legal duty to consult with First Nations on development decisions affecting the land, resources, and environment of native peoples. (6) In the U.S., the Supreme Court established that native tribes can exercise regulatory authority when conduct threatens or has some direct affect on the tribe's political integrity and health and welfare. …

Diversity, composition, and structure of tropical dry forests in Central America

Tropical dry forests have been reduced to less than 0.1% of their original expanse on the Pacific side of Central America and are considered by some to be the most endangered ecosystem in the lowland tropics. Plots 1000 m2 were established in seven tropical dry forests in Costa Rica and Nicaragua in order to compare levels of species richness to other Neotropical dry forest sites and to identify environmental variables associated with species richness and abundance. A total of 204 species and 1484 individuals ≥ 2.5 cm were encountered. Santa Rosa National Park was the richest site with the highest family (33), genera (69), and species (75) diversity of all sites. Species richness and forest structure were significantly different between sites. Fabaceae was the dominant tree and shrub family at most sites, but no species was repeatably dominant based on number of stems in all fragments of tropical dry forest. Central American dry forests had similar species richness when compared to other Neotropical forests. There was no correlation between forest cover within reserves, or precipitation and plant species richness. There was a significant correlation between anthropogenic disturbance (intensity and frequency of fire, wood collection, grazing) and total species richness, tree and shrub species richness, and liana abundance. These results suggest controlling levels on anthropogenic disturbance within reserves should be a high priority for resource managers in Central America. Further research in forest fragments which examine individual and a combination of disturbance agents would help clarify the importance of anthropogenic disturbance on species richness and abundance.

Unlocking potential (reflections of a late developer)

Outlines some of the questions raised during the course of a qualitative research inquiry into the personal consequences of organisational change for directors who are “drivers” of such change. Links these questions to more general issues and trends in the organisation of work (Handy) and for human resource management priorities (Ulrich). Questions the interpretation of these trends in relation to the role of the developer, arguing that effective development involving a third party developer is always dependent on genuine partnership working. Such a way of working is particularly challenging or even threatening to developers, frequently tempting them into hiding themselves behind fashionable theories, tools and techniques, rather than risking their own learning and development while facilitating that of others. Suggests ten keys to unlocking the development potential in oneself and others and that the application of these keys can be a painful process.

Vision 2020: Towards an environmentally sound and sustainable development of freshwater resources in Malaysia

Malaysia has a climate of high humidity, high temperature and abundant rainfall. Rivers supply about 97% of the country's total water needs while ground water accounts for the rest. About 40% of the treated water is lost through man-caused leakages. With a population of 18.3 million people, the total annual domestic, industrial and irrigation water demand is about 11.6 x 106 MI. This figure is projected to rise to 15.2 x 106 MI by year 2000. At present, the total daily water demand is about 4,979 MI and the production capacity is 6,513 MI. Water use and misuse now strain the nation's fragile aquatic environment and natural ecosystems. Current water resource management priorities include water quality improvement, river rehabilitation to restore over-channalized or polluted rivers and development of the inland fisheries potential especially in large man-made reservoirs. A River Basin Information System has been developed to provide integrated information on catchment characteristics, landuse, population and socio-economic profile, river flow, pollution sources, water quality classification, and aquatic biota. Vision 2020 challenges call for a long-term perspective in inland water resource management. Critical post-audits of largescale development and strategic research aimed at alternative and interacting patterns of landwater use are urgently needed.

Recreational Use, Valuation, and Management, of Killer Whales (Orcinus orca) on Canada's Pacific Coast

The management of many ocean wildlife species is left in an institutional void, yet certain species command considerable public attention and have burgeoning management problems. In this paper the non-consumptive recreational use of Killer Whales (Orcinus orca) on Canada's Pacific Ocean coast is used as an example of management difficulties that are associated with oceanic species. Problems associated with jurisdiction and institutional arrangements are coupled to significant levels of biological uncertainty and restricted management options, as well as to management concerns associated with the human domain. The case is conceptualized as an interaction between the human and more general ecological spheres, mediated by the history of the relationship between humans and the species in question. Two routes to regulation are presented, dealing respectively with the human and ecological aspects. Of particular significance is the idea that both types of information are necessary to maximize utility to both the human user and the Whales.Results from an ongoing study of recreational use are presented to indicate some of the variables that have emerged. These are to be interpreted within current resource management infrastructure to create a tenuous situation. The unfortunate logic that results from this study is that if Killer Whales (a high-profile species) in Canada (a well-endowed nation) have not warranted more substantial protection, then the outlook for less well-known marine species in areas of the world where resource management priorities involve more direct survival concerns, is not optimistic.

Determinants of Human Resource Management Priorities and Implications for Industrial Relations

Increasingly, human resource management (HRM) priorities are being treated as dependent variables. Now in addition to studying HRM priorities and practices as determinants of individual outcomes such as performance or absenteeism, researchers are studying how such conditions as competitive strategies and product life cycles shape HRM priorities. This article describes an empirical test of two major hypotheses regarding how competitive strategies and product life cycles are related to HRM priorities. Briefly, it was hypothesized that human resource management priorities would differ for firms in the growth and maturity stages of the product life cycle and they would differ across firms using the competitive strategies of differentiation and cost-efficiency. Data gatheredfrom 300firms in a variety of industries provide support for the hypotheses.
