Find and Monitor Tree Crops for Sustainability
We can monitor agricultural production around the globe using satellites. Recently, there has been an increase in the number of satellites and the frequency and resolution of images being captured. Such large amount of data on a daily and weekly basis can be used with AI to detect crops. Current Best Practices Supply chain companies use manual scouting and surveys up to three times a season ...

Intro to precision forestry
Never before has the interest in preserving natural forests and efficient management of plantations been as great as the present. Demand for wood products is increasing. On the other hand, it is also evident that the remaining forests have to be protected to maintain our quality of life—the very air we breathe depends on them. Therefore, precision management, which has been successfully ...

Sycamore (6ft dbh) with Two Large Cavities at High Elevations next to Playground - Case Study
A TRU survey was performed at Rock Creek Park in Washington, DC on a Sycamore located at a playground. The tree was scanned at six elevations – 7-ft, 6-ft, 5-ft, 4-ft, 3-ft, 2-ft. A complete 360-degree circumferential TRU radar scan was performed for each elevation. The radar waveform data were automatically digitized at 0.2-in (5-mm) increments throughout the entire circumference, which ...

Tree Root Imaging at a Historical Site: In-Depth Assessment of Tree No. 1 – the Copper Beech Tree - Case Study
Background: A mature Copper Beech tree is located in a prominent position at a historical site in the United Kingdom that is known for its archaeological significance and is a major tourist attraction. The tree is of significant amenity value in this public place. It is also very close to a proposed development and is likely to be impacted by the construction of planned new structures. Its ...

Can superfoods boost the planet’s health, too?
As demand for African and Asian tree-based superfoods grows, researchers and entrepreneurs eye ways to maximize benefits for the environment. It can seem like new health food fads pop up every week — fads that often fade as quickly as they appear. Two gaining steam lately, though, may be worth a longer look: baobab and moringa. Traditional fare in parts of Africa (and for moringa, Asia as ...

Effects of different management regimes on mangrove ecosystem services in Java, Indonesia
This new report, published by Wageningen University and Wetlands International, seeks to fill a significant gap in mangrove ecosystem service estimates. While several studies have sought to measure and value the ecosystem services provided by mangrove ecosystems in general, this new piece of research has for the first time conducted separate evaluations for zones that are characterised by ...

A generic approach in estimating vegetation density for hydrodynamic roughness parameterization using high density airborne laser scanning data
Vegetation density is among the important parameters required for determination of hydrodynamic roughness over vegetated areas. High density airborne light detection and ranging (LiDAR) data offer several potentials to improve estimation of vegetation density. Available methods in estimating vegetation density based on regression models did not take into account understorey vegetation and were ...

A methodology to estimate the future extent of dryland salinity in the southwest of western Australia
Received for publication January 27, 2009. In the southwestern agricultural region of Western Australia, the clearing of the original perennial vegetation for annual vegetation-based dryland agriculture has lead to rising saline groundwater levels. This has had effects such as reduced productivity of agricultural land, death of native vegetation, reduced stream water quality and infrastructure ...

Evaluation of a mining project using Discounted Cash Flow analysis, Decision Tree analysis, Monte Carlo Simulation and Real Options using an example
Investments in the mining and minerals industry are considered to be risky. The major challenge of project evaluation is how to deal with the uncertainty involved in capital investment. Discounted Cash Flow (DCF) methods, Decision Trees (DT), Monte Carlo Simulation (MCS) and Real Options (RO) are commonly used for evaluating mining projects. This paper briefly reviews the previous studies, ...

The epistemology of fault tree analysis: an ethical critique
Fault tree analysis (FTA) is one of the preeminent methods for testing the reliability, trustworthiness, and safety of engineered systems. Given their pervasiveness as a major tool for assessing the risks of technology, it is imperative that methodologies such as FTA are valid and sound. If a safety assessment based on an FTA is erroneous, the system may fail to work as expected. In this paper I ...

Plant phenology in Germany over the 20th century
Analysis of observational phenological data has indicated that the length of the vegetation period (VP), here defined as the time between leaf onset and leaf colouring (LC), has increased in the last decades in the northern latitudes mainly due to an advancement of bud burst. Analysing the patterns of spring phenology over the last century (1880–1999) in Southern Germany showed that the strong ...

Biomass estimation equations for tropical deciduous and evergreen forests
In this study, linear and non-linear regression equations were developed to estimate biomass of tropical forests along with estimates of goodness of fit and percentage of errors. Basal area, average height of trees and tree density data from published reports, were used to develop equations to estimate biomass of deciduous and evergreen forests. Basal area and height of trees are found to give ...

Increased inbreeding and inter-species gene flow in remnant populations of the rare Eucalyptus benthamii
Eucalyptus benthamii Maiden & Cambage is a forest tree of interest for conservation and plantation forestry. It is vulnerable to extinction, occurring on the alluvial floodplains of the Nepean River and its tributaries, south-west of Sydney, Australia. These floodplains were largely cleared of native vegetation for agriculture by the mid-1800s. Flooding of the Cox Valley for Sydneys water supply ...
