Koalisi Ornop Pasca Orde Baru: Studi Tentang Jaringan Walhi Dalam Kampanye Isu Hutan, Febryandi Harsono

Masyarakat: Jurnal Sosiologi

One kind of campaign that do by lot of non-governmental organization that focus their movement on environmental issue is forestry issue campaign. Walhi as one of the biggest environmental organization in Indonesia is always powerful on doing forestry issue campaign. This campaign is held in order to show their empathy with forest problems in Indonesia nowadays. Forestry issue campaign is held to aware the government and our society that they need to save our forest is do by work alone as one organization or work together, build network with another non governmental organization in order to make some non governmental …


Accuracy And User Variation Associated With Slope Measurement Using A Laser Hypsometer, C. Hastings, R. C. Weih Jr., H. O. Liechty, R. Harris Jan 2011

Accuracy And User Variation Associated With Slope Measurement Using A Laser Hypsometer, C. Hastings, R. C. Weih Jr., H. O. Liechty, R. Harris

Journal of the Arkansas Academy of Science

Slope measurements are often necessary for assessing features and processes within the natural environment. Land managers often use handheld equipment rather than more complicated surveying equipment in order to measure slopes and to conduct field work efficiently. One type of handheld device used to measure slope is a laser clinometer. In order to determine the accuracy and user error associated with this type of clinometer, slope measurements were taken at multiple locations using two types of equipment: 1) a Haglof Sweden Vertex III Hypsometer with a laser clinometer function and 2) a Topcon GTS-603/AF electronic survey total station which can …


Modeling Loblolly Pine Aboveground Live Biomass In A Mature Pine-Hardwood Stand: A Cautionary Tale, D. C. Bragg Jan 2011

Modeling Loblolly Pine Aboveground Live Biomass In A Mature Pine-Hardwood Stand: A Cautionary Tale, D. C. Bragg

Journal of the Arkansas Academy of Science

Carbon sequestration in forests is a growing area of interest for researchers and land managers. Calculating the quantity of carbon stored in forest biomass seems to be a straightforward task, but it is highly dependent on the function(s) used to construct the stand. For instance, there are a number of possible equations to predict aboveground live biomass for loblolly pine (Pinus taeda) growing in southeastern Arkansas. Depending on stem diameter at breast height (DBH), biomass varied considerably between four different prediction systems for loblolly pine. According to the tested models, individual tree oven-dry biomass for a 50 cm DBH loblolly …
