Abstract:

The goal of ecological restoration is to return degraded or altered ecosystems to their pre-disturbed state with respect to ecosystem structure, function, and composition. In the current study the research objective was to reestablish high levels of biodiversity on two restored pine plantations as well as restore a native pine flatwoods ecosystem. Managed, even-aged pine flatwoods are now the most extensive ecosystem in North Florida, comprising approximately 70% of the forested landscape. Slash pine trees were thinned in the experimental plots to restore the natural slash pine density of nati

Abstract:

Land areas being used unsustainably are depleted and/or degraded. To prevent this from happening and/or to reverse the effects, we need to restore these environments. However, not all restoration practices are equal, and some do not adhere to rigorous standards of sustainability. In this study, restoration guidelines and opinions from field experts were analysed from an SSD perspective. The focus of this thesis was limestone quarries in northern Europe due to quarries’ impacts to the socio-ecological system and the sensitivity of northern ecosystems.

Abstract:

European floodplain grasslands are characterized by periodic flooding and regular management, usually cutting and grazing as part of an agricultural system. Past losses and ecological degradation have been due largely to river regulation and either agricultural intensification or abandonment and have resulted in a substantial reduction in area across Europe. Nevertheless, the remaining resource supports considerable biodiversity and a high level of biological production. A better quantitative understanding of the functioning of these grasslands is required in order to establish effective conse

Abstract:

The restoration of degraded tallgrass prairies can mitigate climate change due to the carbon accrued during the development of grasslands. The focal species, dominant grass Andropogon gerardii, can assist the recovery of grassland ecosystem functioning. Climate, local adaptation, and biodiversity have been found to impact the accrual of carbon in grasslands. This study examined the difference in ecosystem functioning between ecotypes along a dry to mesic precipitation scale.

The two field experiments were established at the same latitude separated by 620 km (corresponding to a precipitation gradient from eastern Kansas to western Illinois), and consisted of a split plot design, with dominant grass source as the whole-plot factor (2 l

Abstract:

In southwest Australia there is a significant need to restore vegetation communities impacted by anthropogenic activities. The series of experiments undertaken over the course of this thesis focus on a notoriously difficult-to-germinate plant family, the Rutaceae. Through the application of field- and lab-based experiments, avenues for seed-based propagation of southwest Australian Rutaceae have been developed, allowing for more effective restoration approaches based upon an improved understanding of seed ecology.

Broadscale forest clearance is a major human-induced disturbance with devastating consequences for biodiversity. With a rise in public awareness of biodiversity, the last few decades have seen an increasing number of reforestation activities aimed at recreating natural habitat.

Rich fens are globally significant wetlands due to their high biodiversity and provision of multiple ecosystem services, such as water purification and climate mitigation. However, many U.K. rich fens have become botanically degraded. This is principally due to abandonment, following the cessation of management (mowing/grazing) and has led to a decline in plant species richness. Although the response to mowing on plant species richness has been well documented across Europe, there is no prior knowledge of this research being undertaken at U.K rich fens.

Abstract:

Biomass and carbon stock of the natural forests in Vietnam are still not clear due to limitation of knowledge and financial. In this paper, the results of estimating biomass and carbon stocks of the natural forests at Me Linh Biodiversity Station are shown. There are two forest types in this study: the forest vegetation restored after shifting cultivation (vegetation type I) and the forest vegetation restored after clear cutting exploitation (vegetation type II). As the results, the estimated biomass of the forest vegetation restored after shifting cultivation is 86.80 ton.ha-1 and the estimat

Abstract:

This thesis explores the nexus between landscape design processes and the conservation of wildlife diversity. Extinction of earth’s unique and diverse animal species is progressing at unprecedented rates, due to humanity’s profound alteration of the natural landscape. Scientific literature increasingly points towards opportunities in the urban and landscape design fields to this issue. Unfortunately, the science and needs of wildlife are rarely integrated in rigorous ways in the planning and design of human landscapes. This gap in professional practice protocols and regulatory frameworks in mu

Abstract:

1928 beslutades att ån Sennan norr om Karlstorp skulle sänkas, rätas ut och delvis kanaliseras för att öka arealen produktiv jordbruksmark. Men åtgärderna orsakade även flera problem både inom och utanför det område som man undersökte innan genomförandet. Dräneringen ledde till att torvmark torrlades vilket orsakar utsläpp av växthusgaser. Vattnets uppehållstid i landskapet kortades och infiltration till grundvattnet minskades. Den biologiska mångfalden minskade genom habitatförlust, alltså färre livsmiljöer, och även genom ökade mängder lösta organiska ämnen i vattnet. Dessa negativa effekter

Abstract:

Globally, ecosystems provide services of almost twice the value of global gross national product (Costanza et al., 2006). The Buffalo City Municipality (BCM), South Africa contains biodiversity of national and international importance (Pierce, 2003; Pierce et al., 2005). Despite this, the municipality continues to experience loss of both urban and rural biodiversity (Buffalo City Municipality, 2006a). This study sought to determine the status of biodiversity, and the potential for ecosystem services to contribute to conservation, within the BCM. Biodiversity features, including ecosystem type,

Abstract:

Durante muitas décadas, extensas áreas de florestas nativas têm sido sistematicamente destruídas no Brasil, muitas delas dando lugar a plantações florestais para fins industriais. A adequação à legislação ambiental recente, no que se refere à manutenção de áreas de preservação permanente e de reservas legais, passou a gerar a necessidade de reversão de áreas ocupadas com plantios comerciais para florestas nativas. Este trabalho teve como objetivo estudar a efetividade de técnicas para acelerar a regeneração natural da vegetação nativa em talhões de Eucalyptus saligna abandonados. O estudo foi

Abstract:

Cord-forming fungi (CFF) are an assemblage of saprotrophic fungi which can use complex foraging organs of longitudinally arranged hyphae to join up disparate substrates in a patchy resource environment. Their importance to woodlands lies, mainly, in their ability to modify nutrient cycling and soil structure. Therefore, in order to enable woodlands to continue to thrive in terms of their health and ecosystem function, it is necessary to understand the factors contributing to the establishment, success and diversity of this group. Whilst work to date on CFF has focussed on their physiology and

Abstract:

1. Seed bank and seed rain represent dispersal in time and space. They can be important sources of diversity in the rural landscape, where fragmented habitats are linked by their histories. 2. Seed bank, seed rain and above-ground vegetation were sampled in four habitat types (abandoned semi-natural grassland (ABA), grazed former arable field (FAF), mid-field islet (MFI) and grazed semi-natural grassland (SNG)) in a rural landscape in southern Sweden, to examine whether community patterns can be distinguished at large spatial scales and whether seed bank and seed rain are best explained by cur
