Increasingly, weeds have been taking on global distributions. With the proliferation of invasive weeds has come the challenge of managing these species over broad geographical regions, with diverse habitats and political jurisdictions. Here, we review the management of Mikania micrantha Kunth (Asteraceae; mile‐a‐minute) throughout its invaded range, extending through most of the Pacific islands and southern and south‐east Asia. Context matters when determining the best course of action for managing M. micrantha, as it has invaded a large variety of agricultural and natural systems. In Queensland, Australia and Florida, USA, M. micrantha has been targeted in relatively successful eradication campaigns, highlighting the importance of early detection and rapid response methods, while elsewhere in its invaded range, populations are either still increasing or showing limited signs of decline. An inter‐regional approach to research and management should incorporate successful management strategies employed throughout the invaded range including, but not limited to, chemical and cultural control practices, manual and mechanical control, classical biological control using the rust fungus Puccinia spegazzinii, plant–plant competition and integrated approaches utilising two or more control methods concurrently. Additional knowledge of M. micrantha genetics is required to determine if management approaches could be fine‐tuned for particular populations. Countries bordering the Mekong River formed a network in 2011 to co‐ordinate the management of invasive species such as M. micrantha. Expanding such a collaborative approach to other regions could further reduce populations of M. micrantha and limit its spread. 相似文献

This paper conceptualises and evaluates so-called co-management zones as an approach for user participation in urban forestry, specifically in the management of public woodland edges bordering residential areas. Co-management zones can metaphorically be viewed as ‘ecotone-like’ spaces, i.e. zones where overlapping interest – in this case residents’ and municipal authorities’ – can be used to create richness and meetings rather than boundaries. Building on the perspectives of ecotone thinking and governance arrangements, co-management zones in the Danish residential area of Sletten in Holstebro were evaluated. The presented case study combined interviews with residents and interviews with three key green space professionals who had led the planning, design, establishment and management of the woodland and the implementation of co-management. The resident participation in the co-management zone was also assessed and photo documented in a field survey, categorising individual households according to type and degree of physical signs of participation. Findings illustrate the potential of co-management zones to initiate collaboration between residents and public woodland managers in creating recreationally valuable and varied meetings between private gardens and urban woodlands. Challenges with establishing co-management zones were also highlighted, especially the need for clear guidelines and continuous communication between residents and the municipality. Perspectives and implications related to residents, managers and green space quality are discussed. 相似文献

朱熹的礼治思想正是“后王安石时代”士大夫政治文化的体现。其中所蕴含的政治哲学理念主要包括了三个方面:1)德礼先于政刑又不废政刑的为政原则论;2)严正而不失温情、强调君礼臣忠的君臣关系论;3)主张“与民同乐”、“以民为本”的君民关系论。总而言之,朱熹的礼治思想是两宋时期“中国传统政治思想的哲学化转型”过程中的一个典型代表。 相似文献

Ian Jeffreys 《Small-Scale Forestry》2004,3(1):99-117
Small-scale farm forestry has the potential to offer many benefits both to landholders and the wider community. As with all
changes in land-use practices, there are associated benefits and costs and these are not uniformly distributed. They have
varying impacts on the different values, aspirations, goals and objectives that exist within the community. Furthermore, the
community does not consider these values, aspirations, goals and objectives of equal importance. The degree of concern can
vary from minor to high and overriding all other considerations. When evaluating farm forestry options it is necessary to
address all of these concerns. This paper examines the combined use compensatory and non-compensatory multi-criteria analyses
to evaluate forestry options, in a case study for the Darling Downs region of Queensland, Australia. These aggregation techniques
are found to be highly complementary and together provide a comprehensive analysis. The compensatory technique provides a
sound measure of overall performance of a forestry system, whereas the non-compensatory technique alerts decision-makers to
presence of particularly poor performance with respect to individual criteria. The compensatory technique used is simple and
understandable even for those with non-mathematical backgrounds. This analysis can identify and aid communication of the relative
benefits and costs, and trade-offs, between economic, environmental and social considerations. 相似文献
