“…It is interesting that the conditions in the oil palm understorey are in general more similar to those in the high canopy of emergent rainforest trees: organisms from this layer of the forest may therefore face fewer problems in colonizing oil palm than those that live in the more extensive forest understorey. Indeed, the single species of the epiphytic bird's nest fern that survives in oil palm plantations appears to be a high-canopy species, with the forest understorey species becoming extinct [57,65]. Studies showing changes in numbers of forest species on conversion to oil palm, rather than changes in overall richness or other parameters.…”

The conversion of natural forest to oil palm plantation is a major current threat to the conservation of biodiversity in South East Asia. Most animal taxa decrease in both species richness and abundance on conversion of forest to oil palm, and there is usually a severe loss of forest species. The extent of loss varies significantly across both different taxa and different microhabitats within the oil palm habitat. The principal driver of this loss in diversity is probably the biological and physical simplification of the habitat, but there is little direct evidence for this. The conservation of forest species requires the preservation of large reserves of intact forest, but we must not lose sight of the importance of conserving biodiversity and ecosystem processes within the oil palm habitat itself. We urgently need to carry out research that will establish whether maintaining diversity supports economically and ecologically important processes. There is some evidence that both landscape and local complexity can have positive impacts on biodiversity in the oil palm habitat. By intelligent manipulation of habitat complexity, it could be possible to enhance not only the number of species that can live in oil palm plantations but also their contribution to the healthy functioning of this exceptionally important and widespread landscape.

“…Cryptic taxa are increasingly recognised in tropical ecology (e.g. Silvera et al 2003;Fayle et al 2011). Improved taxonomy and genetic tools may eventually reduce such uncertainties, but in the meantime changing names and confusions of identity will continue.…”

We reply to Webber et al. (2011). Our study, Sheil and Padmanaba (2011), was a preliminary assessment of the alien Neotropical tree Cecropia around Bogor, West Java, Indonesia. We highlighted the need for low-cost assessment approaches for addressing alien species and considered what might be achieved by local actors with limited resources. We successfully characterised the local distribution of Cecropia and identified, addressed and illustrated various concerns. Based on these results we asked how such studies might be useful and how they could be improved. Webber et al. criticise our study but fail to engage with its goals. Certainly, low-input local approaches lack the sophistication and rigour of larger international efforts, but such comparisons are unhelpful. Aside from a number of misunderstandings, we find Webber et al.'s principal arguments overstated, and unsupported by published information. The evidence that Cecropia causes harm is unconvincing; species-level identification is overemphasised; and the insistence on completing detailed research before considering management options is problematic. We offer some positive conclusions and repeat our plea for the development of effective low-input methods for evaluating and addressing naturalised organisms.

“…Surprisingly, bird's nest fern populations are resilient to habitat change, with abundances decreasing in logged forest, but increasing in oil palm plantation (90, 53 and 117 ferns per hectare in primary forest, logged forest and oil palm plantation respectively (Turner, 2005; see also Padmawathe et al, 2004). However, only the high canopy species A. nidus survives in oil palm plantations, perhaps due to its pre-adaptation to hot and dry environments (Fayle et al, 2011). Despite substantial reductions in total arthropod abundance (67.2% decrease) and biomass (87.5% decrease) between ferns in primary forest and those in oil palm plantation (Turner & Foster, 2009), the numbers of species of ants per fern does not change (Fayle et al, 2010).…”
