Wildlife Conservation in Bornean Timber Concessions

Based on an in depth evaluation of the literature, and vast session with specialists, we’ve got assessed the sensitivity of Bornean vertebrates to the direct and oblique results of wooden harvest. Well-implemented selective logging has a surprisingly constrained direct impact on natural world populations: few species seem quite sensitive, a few benefit, some decline. However, modern control practices in Indonesian Borneo usually purpose a decline in wildlife populations. Guidelines for sustainable forest management are mainly focused on timber, with few specific recommendations on how to sustainably control flora and fauna populations in wood concessions. Based on our findings, we provide extensive natural world control recommendations, stating the significance of maintaining understory plants and large timber for fruit, seed, dead timber, and tree hole production, restricting cover gaps, and decreasing looking and flora and fauna alternate in concessions. In addition, we offer unique control recommendation on high priority species of Bornean vertebrates.

There is an growing awareness that flora and fauna species in Indonesian Borneo want forests which can be managed for sustainable wood extraction if they’re to live to tell the tale in the long term (Colón 1999, Lammertink 2004b, Sheil et al. 2004). In the past few a long time, conservation efforts have focused strictly on protected areas, but recent insights have counseled that those reserves are inadequate to guard rare, threatened species. Not best is the included region network fragmented (Jepson et al. 2002), but forests also are disappearing even within those covered regions (Fuller et al. 2003, Curran et al. 2004).

Kalimantan’s included place network is failing for diverse ecological, socioeconomic, and political motives (Kramer et al. 1997, Rijksen and Meijaard 1999, Jepson et al. 2001, 2002). Ineffective control, however, is a dominant factor. Management, if any, is directed from nearby or country wide places of work, however without ok on-the-ground team of workers to provide even fundamental safeguards, many protected regions stay paper parks (cf., Bruner et al. 2001, Rodriguez and Rodriguez-Clark 2001). Poor political support for active conservation management is a global trouble this is simplest slowly enhancing. Thus, conservation remains underfunded (e.G., Balmford and Whitten 2003), and tax systems supplying economic repayment for the usage of environmental offerings remain undeveloped.

Direct economic benefits along with wood manufacturing provide an incentive to keep forests and a manner to generate conservation benefits, specially when numerous financial and political forces are encouraging improved management practices. This, and the reality that wooded area loss threatens each conservation hobbies and timber manufacturing explains why tropical manufacturing forestry and conservation are an increasing number of locating common ground. Whether manufacturing forestry has the potential to halt woodland decline, or to in any other case benefit conservation, is disputed (Bowles et al. 1998, Lugo 1999, Putz et al. 2000), however we wish to emphasise the pragmatic ecological foundation for concerning timber concessions in flora and fauna conservation.

Many Bornean wildlife species persist at handiest barely altered densities in selectively harvested forests, and nicely-managed manufacturing forests can offer adequate habitat for most species (Meijaard et al. 2005). Still, little is understood about how exceptional control procedures affect Bornean natural world, and even much less approximately how wildlife conservation might be balanced with industrial production advantages. Here we report on this problem, based totally on a literature review of Bornean natural world and logging (Meijaard at al. 2005). We justify and description practical suggestions for advanced woodland control that goes beyond modern requirements.

Some terms require definition. In Indonesia, as in most tropical countries, logging is selective: only business species over a fixed diameter restriction, i.E., typically >50 cm dbh, are removed. Various management stages are followed to keep away from immoderate harm to the final forest, starting with harvest planning, road and skid path design, and tree felling strategies typically referred to as decreased effect logging (RIL).

We compiled and analysed facts sets on how manufacturing forestry influences Bornean wildlife. We did this by way of reviewing all available published and unpublished literature on Bornean natural world species, which includes mammals, hen, reptiles, and amphibians, and consulting broadly with nearby and worldwide specialists. We analysed 282 guides derived from Borneo-primarily based studies (Meijaard et al. 2005, Meijaard and Sheil, unpublished manuscript, Meijaard et al., unpublished manuscript), and a similar quantity of applicable guides primarily based on studies elsewhere in Southeast Asia (Meijaard et al. 2005).

We decided on positive species and assessed their tolerance to logging, i.E., both the direct impacts and related consequences that regularly comply with such as searching and wooded area fragmentation.

We supplied an overview of the sensitivity of Bornean wildlife to logging, together with commonplace trends among species which can be both negatively or undoubtedly affected (Meijaard et al., unpublished manuscript). On this foundation, the general ecological consequences of productive forestry and unique wildlife control alternatives can be examined, and suggestions might be developed to enhance wooded area management. As part of this manner we taken into consideration species-specific habitat necessities, permitting us to offer particular control tips to guard those woodland attributes. An review of the manner may be located in Sheil and Meijaard (2005).
