Diverse stakeholders and multiple management options pose challenges to restoration planning and management. Analytic hierarchy process (AHP), a multicriteria decision‐making tool, can be effectively used for incorporating stakeholders' perceptions in planning. By using Red sanders (Pterocarpus santalinus L.) restoration as a case study, we demonstrate its suitability in eliciting stakeholders' perceptions about the most suitable management option, and their expectations from it. Four key stakeholder groups, Administrators, Field Officers, Community, and Knowledgeable Sources, were used to identify the most suitable management option from Government Management (GM), Quasi‐Government Management, Community Forest Management (CFM), and Private Management. Results indicate that stakeholders' preferences for management options were not homogeneous. Consolidated priorities across all the stakeholder groups indicated the CFM (34%) as the most preferred option followed by the GM (31%). With an average weight of 56%, the ecological criterion was considered as the most important. The ability of the managements in reducing disturbances (23%), improving Red sanders density (18%), improving ecosystem services (15%), and in improving rural livelihoods (15%) were considered important. The preferences of the Administrators and the Field Officers for the GM indicated their support for the top‐down management approach, and skepticism toward the CFM, a bottom‐up approach. Compared to the Administrators, the Field Officers' lack of support for the CFM was surprisingly more pronounced. Results indicate the usefulness of the AHP technique in identifying common grounds between the diverse stakeholders, and the management, in identifying a suitable management alternative and in prioritizing preferences. 相似文献

Hygrocybe rubida, a new species in subsection Squamulosae of section Coccinea, collected from tropical evergreen forests of Western Ghats of Kerala is formally described. The species is characterized by a bright red, dry pileus and stipe; ovoid to subamygdaliform spores; a distinctly sterile lamella-edge with crowded cheilocystidia and a trichodermial pileipellis. 相似文献

The role of species richness, functional diversity and species identity of native Florida sandhill understory species were
tested with Imperata cylindrica, an exotic rhizomatous grass, in mesocosms. I. cylindrica was introduced 1 year after the following treatments were established: a control with no native species, five monocultures,
a grass mix treatment, a forb mix treatment, and a 3-species treatment and a 5-species treatment. Monthly cover, final biomass,
root length, root length density (RLD) and specific root length (SRL) of all species were determined for one full growing
season. There was a significant negative linear relationship between the cover of native species and I. cylindrica (r
2 = 0.59, P = 0.01) and a negative logarithmic relationship between the biomass of native species and I. cylindrica (r
2 = 0.70, P = 0.003). There was no diversity–invasibility relationship. Grasses proved to be the most resistant functional group providing
resistance alone and in mixed functional communities. Repeated measures analysis demonstrated that treatments including Andropogon virginicus were the most resistant to invasion over time (P < 0.001). Significantly greater root length (P = 0.002), RLD (P = 0.011) and SRL (P < 0.001) than all of the native species and I. cylindrica in monocultures and in mixed communities made A. virginicus successful. The root morphology characteristics allowed it to be a great competitor belowground where I. cylindrica was most aggressive. The results suggest that species identity could be more important than species or functional richness
in determining community resistance to invasion. 相似文献
