“…Typically, priority areas are identified where invasive species are kept below a certain threshold through continuous management (Mack and Lonsdale, 2002;Myers et al, 2000;Thomas and Reid, 2007). Every successful control programme has to agree on clear objectives (Anderson et al, 2003;Baker et al, 2005;Genovesi, 2007;Wittenberg and Cock, 2001).…”

“…A number of decision aid tools have been developed to support the setting of appropriate objectives for control programmes. These tools may for instance help to define priority species and areas (Hiebert, 1996;Tassin et al, 2006;Wittenberg and Cock, 2001), or acceptable levels for the population density of an invasive species -a concept that has a long tradition in agricultural weed management and biological control (Hulme, 2006;Smith et al, 2006;Thomas and Reid, 2007). Often a detailed consideration of the stakeholders' valuation of a management attempt is necessary.…”

“…Major obstacles are the risk of an environmental contamination of natural areas with the chemical, non-target effects on native species, or the evolution of pesticide-resistance by the invasive species (Baker et al, 2005;Lodge et al, 2006;Myers and Bazely, 2003;Wittenberg and Cock, 2001). In the case of biological control a natural enemy such as a herbivore or pathogen is introduced with the aim that the introduced organism controls the invasive species (Babendreier, 2007;Messing and Wright, 2006;Mack and Barrett, 2002;Thomas and Reid, 2007). Major risks of the introduction of an (alien) organism in biological control programs are non-target effects on the native biota.…”

It is increasingly expected from environmental research such as landscape research that science directly contributes to the solving of pressing societal problems. However, despite increased efforts to direct research towards societal problems, it is not obvious if science has become more effective in supporting environmental problem-solving. We present in this article a framework that facilitates the analysis and design of problem-orientation in research fields. We then apply the proposed framework to a concrete example of a problem-oriented landscape research field -namely research on biotic invasions. Invasion research addresses the problem that some organisms, that have been introduced by humans to a new geographic area where they were previously not present, spread in the landscape and pose negative impacts.We argue that problem-oriented research is more than applied research. Besides research on specific questions it also encompasses boundary management, i.e., deliberations among experts and stakeholders on the framing of adequate research questions about processes, values and practices for effective problem-solving. We postulate that such research may assist problem-solving in three ways, by analysing causal relationships (systems knowledge), clarifying conflicts of interests and values (target knowledge), or contributing to the development of appropriate means for action (transformation knowledge).We show that over the past decades a broad range of different research approaches has emerged in the young field of invasion research in order to produce systems, target and transformation knowledge for invasive species management. Early research in the field was dominated by the development of systems knowledge, but increasingly the three knowledge forms are Boundary management in invasion research is mainly restricted to informal networks (communities of practice), while formal processes such as transdisciplinary research are scarce. We suggest that the paucity of structured and explicit boundary management processes will limit the future development of a more effective science for invasive species management. In particular, we envisage three obstacles that can only be removed through explicit boundary management. First, the existing theoretical frameworks are currently only partly able to integrate natural and social sciences research on the processes underlying invasions. Second, a clarification of the normative thinking about alien plant invasions is needed. Third, research on transformation knowledge has so far not fundamentally challenged the existing conceptual framing and institutional setup of invasive species management.

“…Classical biological control has achieved successful pest control in a number of cases, although in general there is a lack of long term, quantitative and objective monitoring (i.e. embedded in ecological theory) of such programmes, which makes evaluation of the overall costs and benefits difficult (Thomas & Reid, 2007). Secondly, augmentation biological control involves the application of natural enemies without the expectation of permanent establishment.…”

“…Some biologists and geographers have conducted various researches on ecological characteristics of S. alterniflora and its impacts on environment [1][2][3][4][5][6][7]. In recent years, some evidence has been reported that S. alterniflora could compete with native plants, threaten native ecosystems and coastal aquaculture, and cause declines in local biodiversity [2][3][4].…”

Large-scale coastal reclamation has caused significant changes in Spartina alterniflora (S. alterniflora) distribution in coastal regions of China. However, few studies have focused on estimation of the wetland vegetation biomass, especially of S. alterniflora, in coastal regions using LiDAR and hyperspectral data. In this study, the applicability of LiDAR and hypersectral data for estimating S. alterniflora biomass and mapping its distribution in coastal regions of China was explored to attempt problems of wetland vegetation biomass estimation caused by different vegetation types and different canopy height. Results showed that the highest correlation coefficient with S. alterniflora biomass was vegetation canopy height (0.817), followed by Normalized Difference Vegetation Index (NDVI) (0.635), Atmospherically Resistant Vegetation Index (ARVI) (0.631), Visible Atmospherically Resistant Index (VARI) (0.599), and Ratio Vegetation Index (RVI) (0.520). A multivariate linear estimation model of S. alterniflora biomass using a variable backward elimination method was developed with R squared coefficient of 0.902 and the residual predictive deviation (RPD) of 2.62. The model accuracy of S. alterniflora biomass was higher than that of wetland vegetation for mixed vegetation types because it improved the estimation accuracy caused by differences in spectral features and canopy heights of different kinds of wetland vegetation. The result indicated that estimated S. alterniflora biomass was in agreement with the field survey result. Owing to its basis in the fusion of LiDAR data and hyperspectral data, the proposed method provides an advantage for S. alterniflora mapping. The integration of high spatial resolution hyperspectral imagery and LiDAR data derived canopy height had significantly improved the accuracy of mapping S. alterniflora biomass.
