“…They also responded differently to the level of microhabitat disturbance found within logged forest, with native species appearing to be associated with less intensive disturbance whilst the invasive R. rattus, which is known to pose a threat to native species through competition for resources and direct interference, demonstrated a preference for more degraded sites. We suggest that reduced-impact logging policies that minimize forest disturbance, as well as the rehabilitation of highly degraded areas that have already been logged, will provide added benefits in terms of invasion resistance, in addition to well-documented direct benefits in terms of carbon and biodiversity (Putz et al 2008b). Without these, we risk compromising the biodiversity value of logged secondary forests by facilitating the spread of invasive species.…”

Influence of microhabitat structure and disturbance on detection of native and non-native murids in logged and unlogged forests of northern Borneo

Abstract:Understanding the habitat preferences of native and non-native species may offer valuable insights into the mechanisms favouring invasion of disturbed habitats. This study investigated the determinants of trap-site detection probability of three native (Maxomys surifer, Maxomys whiteheadi and Leopoldamys sabanus) and one invasive (Rattus rattus) species of terrestrial murid (Muridae) in logged and unlogged forests of northern Borneo. We established four and two trapping grids in repeatedly logged and unlogged forest, respectively, for a total of 500 sampled trap sites. From these, we obtained 504 detections of the four species over 3420 trap nights. For each species, probability of detection was modelled as a function of both the structural components and disturbance level of the forest patch measured around each trap site. Each of the four species showed contrasting microhabitat preferences: M. surifer favoured increased canopy closure and intermediate ground and understorey vegetation cover; M. whiteheadi preferred increased ground vegetation cover and canopy height; L. sabanus favoured sites with larger amounts of coarse woody debris and less leaf litter; and R. rattus was associated with increased ground vegetation cover. Within logged forest, detection probabilities of the three native species did not vary significantly with level of patch disturbance, whereas that of the invasive R. rattus increased markedly in more degraded sites. This latter finding will have increasingly important implications when considering the rapid degradation of forests in the region, and the resulting expansion of suitable habitat for this competitive species.

“…Such questions would also arise if a REDD scheme would account for carbon stocks in wood products such as furniture. The case of Vietnam also shows that, in policies like REDD, forest degradation is as critical as deforestation (40).…”

In some countries across the globe, tropical forest cover is increasing. The national-scale reforestation of Vietnam since 1992 is assumed to contribute to this recovery. It is achieved, however, by the displacement of forest extraction to other countries on the order of 49 (34 -70) M m 3 , or Ϸ39% of the regrowth of Vietnam's forests from 1987 to 2006. Approximately half of wood imports to Vietnam during this period were illegal. Leakage due to policies restricting forest exploitation and displacement due to growing domestic consumption and exports contributed respectively to an estimated 58% and 42% of total displacement. Exports of wood products from Vietnam also grew rapidly, amounting to 84% of the displacement, which is a remarkable feature of the forest transition in Vietnam. Attribution of the displacement and corresponding forest extraction to Vietnam, the source countries or the final consumers is thus debatable. Sixty-one percent of the regrowth in Vietnam was, thus, not associated with displacement abroad. Policies allocating credits to countries for reducing deforestation and forest degradation should monitor illegal timber trade and take into account the policy-induced leakage of wood extraction to other countries.leakage ͉ reducing emissions from deforestation and forest degradation ͉ reforestation ͉ illegal timber trade ͉ forestry policies

“…Hal ini dapat berakibat pada potensi meningkatnya jumlah pohon yang dapat ditebang yang berarti meningkatnya degradasi hutan. Beberapa penelitian di hutan alam sekunder menyebutkan bahwa jumlah pohon yang dipanen dalam satu hektar sangat menentukan kelestarian produksi hutan (Bertault and Sist, 1997;Sist et al, 1998;Sist et al, 2003b), walaupun telah dilakukan teknik pemanenan yang berdampak rendah (Reduced Impact Logging/RIL) yang dipercaya dapat mengurangi kerusakan tegakan tinggal (Putz et al, 2008b;Sasaki et al, 2012) (Putz et al, 2008a;Putz et al, 2008b;Sasaki et al, 2012). Selain itu, daur tebangan juga diperpendek dari 35 tahun menjadi 30 tahun, yang berarti dapat diasumsikan bahwa tegakan tinggal yang sama akan menghasilkan tegakan yang kurang lebih sama pada pada saat sebelum penebangan.…”

ABSTRAKLaju degradasi hutan alam berkontribusi cukup besar terhadap tingginya emisi karbon yang terjadi di Indonesia. Perubahan sistem silvikultur TPTI dengan penurunan daur tebangan dan diameter yang dapat ditebang berpotensi untuk meningkatkan degradasi hutan alam. Penelitian ini bertujuan untuk menganalisis dinamika cadangan karbon yang terjadi pada hutan alam produksi apabila dilakukan kegiatan pembalakan dengan sistem silvikultur Tebang Pilih Tanam Indonesia (TPTI) 2009. Metode yang digunakan dalam penelitian ini adalah matriks transisi. Hasil yang diperoleh dalam penelitian ini adalah: (1) karbon tersimpan dalam biomassa hutan yang dikelola dengan sistem TPTI baru dengan daur 30 tahun lebih rendah dibandingkan karbon tersimpan dalam biomassa hutan yang dikelola dengan sistem TPTI lama dengan daur 36 tahun, dan (2) peningkatan intensitas tebangan menyebabkan perbedaan karbon tersimpan dalam biomassa yang semakin tinggi antara sistem TPTI lama dan baru.

Improved Tropical Forest Management for Carbon Retention

Abstract: Using reduced-impact timber-harvesting practices in legally logged tropical forests would reduce global carbon emissions by 0.16 Gt/year at a modest cost and with little risk of "leakage" (increased carbon emissions elsewhere).
