The aim of this study is to identify the types of trees that are sought and logged on Gunung Palung National Park. The method used was interviews with 45 loggers who had joined the UMKM program in collaboration between Yayasan ASRI, Health in Harmony, and Gunung Palung National Park Office. A field survey was conducted to find out the number of active loggers cutting down on Gunung Palung National Park. The result identified 15 families as tree species which m

Abstract:
This comprehensive review examines thirty-nine data loggers and their associated literature, systematically critiquing their design and implementation. The integration of data loggers in farm monitoring proves cost-effective, enabling the simultaneous monitoring of multiple parameters without human intervention. The accrued data, when logged over time, contributes to more accurate weather predictions, empowering farmers to strategically plan for upcoming seasons. However, the review reveals a prevalent issue among existing data loggers: many cannot read and record various weather parameters co

Abstract:
Event data loggers are frequently used to record the date and time of tip events in tipping-bucket rain gauges. The HOBO® pendant event data logger is one such commercially available device commonly used for this purpose. It can record the contact closure of a TBGR reed switch at a maximum timing resolution of 1 s, tied to the timing of the logger clock, which is set each time the logger is launched. These event loggers are ideal for the routine recording of rainfall. This paper addresses the issue of whether they can also be relied upon when estimating short-term intensities, for which they w

The use of commercial data loggers and gypsum blocks to monitor the matric potential of water in soil was evaluated in the laboratory and at 2 field sites. A set of calibration resistors that simulated a matric potential range of —20 to —2120 kPa was developed that showed close agreement with data that was originally used to develop algorithms for the loggers. Data loggers used in experiments were calibrated against the resistors so output values could be re-scaled to that of the resistor set. Close agreement was found between the matric potential of soil, which was estimated from filter paper

The upstream extent of coastal cutthroat (Oncorhynchus clarki clarki) and rainbow (Oncorhynchus mykiss) trout distribution in logged and unlogged streams of the western Cascade Mountains appears to be primarily constrained by steep channel gradient and sparse pool habitat.

The upstream extent of trout distribution appears to be resilient to the combined impacts of historic and current forest management activities, in the absence of impassable road culverts.

Abstract:
Natural disturbances in European production forests are undesired from an economic perspective but are important drivers of biodiversity. The removal of damaged timber to restore economic value is accompanied by negative effects on various species groups, particularly breeding bird communities, and can hinder natural regeneration. However, little is known about the effect of postdisturbance logging on bird assemblages in winter when temperatures are low and food resources are unpredictable. We conducted fixed-radius point counts of wintering birds in forest stands logged or unlogged after wind

Upland rice has been cultivated by intercropping patterns on the logged area of the teak forest in Java Island for a long time. However, the activities of upland rice farming are still subsistence and not profit-oriented. This study aims to determine the feasibility of upland rice farming on the logged area of teak forests based on farming productivity. Data was collected using a survey and interview to 30 farmers who cultivated upland rice on the logged area of Perhutani teak forest.

The responses of the reindeer lichens (Cladina stellaris, C. rangiferina, and C. mitis) to logging and fire were compared in lichen-rich forest stands in northwestern Ontario. In the summer of 1992, reindeer lichen cover, in total and by species, was visually estimated and detailed notes were taken on reindeer lichen conditions, modes of reproduction, and substrate use on 34 undisturbed, burned, or logged sites. While virtually no reindeer lichens survived forest fire, much of the reindeer lichen cover remained after logging. Reindeer lichen cover increased with time since fire. Total reindeer

Sminthopsis leucopus ate a wide variety of prey, including vertebrates. The observed similarity between the invertebrates in scats and pitfall traps in the preferred habitat (logged ridges) indicates that S. leucopus feeds opportunistically. Adequate food resources were available in all ridge habitats yet S. leucopus were captured predominantly in only logged ridge habitat. We conclude that food availability did not influence h

Timber production, cutting and extraction is impacting vast areas of tropical forests, highlighting the need for management strategies to promote sustainable recovery of logged forests. However, limited information is available on how logging and enrichment planting affect forest structure, commercial tree species, and timber volume recovery. In this study, we assessed the effects of timber cutting and extraction (“logging”) on forest structure, regeneration of key timber species, and volume recovery across different logging intensities.

Leaf fall was collected at 30 sampling points in each plot, and identified to species.Dipterocarpaceae, Euphorbiaceae, Lauraceae, Fagaceae and Meliaceae are important tree families in both plots with regard to their contribution to total basal area, tree density and annual leaf fall. The total number of tree species was higher in the primary forest plot (267) than in the

Abstract:
A sediment rating curve developed as a linear regression on logged values which is back-transformed must be corrected for the bias introduced by the log transformation. This article shows that the variances are identical for linear regressions based on values of logged load and logged concentration from the same data set. This means that the bias correction factoss 101.1513σ2 for the back-transformed regressions are equivalent. Therefore a back-tranoformed log regression based on loads corrected for bias gives identical sedimett discharges to a back-transformed log regression on concentrations

Abstract:
As part of a larger study to examine the operational feasibility, ecological benefits, and environmental impacts of partial-harvest logging in riparian buffers along boreal mixedwood forest streams, we determined the effects on summer stream temperatures. Three logged study reaches were compared with three reference reaches over two prelogging and two postlogging summers. Partial-harvest logging resulted in an average removal of 10%, 20%, and 28% of the basal area from riparian buffers at the three logged sites. At the two more intensively logged sites, there were small (<10%) reductions in
