  • Comparing RGB-based vegetation indices with NDVI for agricultural drone imagery

    Abstract Agribotix conducted a post hoc test of two vegetation indices, VARI and TGI, that used only the three visible-band signals from an unmodified CMOS camera. The results were compared to NDVI, which is generally considered to be a reliable measure of field health and the underlying RGB image. While the results are somewhat encouraging in limited cases, it is clear that neither VARI nor ...

  • Climate and Economic Benefits of Agroforestry Systems

    Introduction Agriculture is well known as a significant contributor to global greenhouse gas emissions, but emerging practices in land management have the potential to curtail these emissions and reverse much of the ecological and climate harm caused by overly intensive systems. One such practice, cultivation and conservation of trees in agricultural practices, or agroforestry, is an important ...

  • Landscape trees benefit from potassium-based superabsorbent polymer-amended backfill soil

    Weiner (1975) put it aptly when he stated that “However rewarding the act of tree planting may be, watching a young tree slowly die can be spiritually defeating.” Landscape plants, noted Richard Harris (1983) in his well-known “Arboriculture” book, “probably suffer more from moisture-related problems than from any other cause.” The success of tree planting ...

  • Biomass harvesting: how forest thinning can help prevent wildfires

    Every year, wildfires plague the nation. Once there’s an ignition source, dry foliage in country areas can quickly go up in flames, spreading through woodlands or grasslands quickly. While some wildfires can be small, others can be devastating and blaze through thousands of acres. While there’s no way to predict where wildfires may start, there are ways to minimize the damage of ...

  • Technology that is making plants grow bigger and better

    This article outlines new and improved technology that is enabling growers to increase their yield and output of their crops. The technology includes carbon dioxide (CO2) monitors and controllers, soil moisture sensors, plant based sensors such as sap flow and dendrometers, and nutrient sensors such as EC and TDS sensors. All of the equipment can be automated and data sent to your smart phone or ...

  • A Moment Matching Approach for Generating Synthetic Data

    ABSTRACT Synthetic data are becoming increasingly important mechanisms for sharing data among collaborators and with the public. Multiple methods for the generation of synthetic data have been proposed, but many have short comings with respect to maintaining the statistical properties of the original data. We propose a new method for fully synthetic data ...

  • Opportunities to Generate Cash Flow for Family Forests Using Conservation Payments

    There has been significant discussion about the merits of stacking conservation payments over the past few years. A simple explanation for credit stacking is when landowners are paid for conservation practices on their property that provide multiple benefits to the environment. Examples of credits types that might be stacked include: endangered species, water quality, wetlands, and carbon. ...

  • Earth Day 2016 - How trees help to reduce flooding

    This year’s Earth Day will be held on April 22nd, and will be the 46th event of its kind. The event brings together people from all over the world to raise awareness, support and participation for environmental protection. This year’s event has a specific goal, dubbed ‘Trees for Earth’, which aims to plant 7.8 billion trees by 2020. This ambitious goal is part ...

  • The herbicide atrazine induces hyperactivity and compromises tadpole detection of predator chemical cues

    The ability to detect chemical cues is often critical for freshwater organisms to avoid predation and find food and mates. In particular, reduced activity and avoidance of chemical cues signaling predation risk are generally adaptive behaviors that reduce prey encounter rates with predators. Here, we examined the effects of the common herbicide atrazine on the ability of Cuban tree frog ...

  • Global deforestation is decreasing. Or is it?

    A new look at the complex picture of land use change suggests that when it comes to forests, we’re far from being out of the woods. It started, as many things do, with a rumor. In 2013 Matt Finer, a researcher with the Amazon Conservation Association, heard from locals that someone was cutting down rainforest deep in the Peruvian Amazon, far from prying eyes. So ...

  • Stemflow and its controlling factors in the subshrub Artemisia ordosica during two contrasting growth stages in the Mu Us sandy land of northern China

    The yield of stemflow from vegetation is mostly affected by rainfall and canopy structure, but few past studies have paid attention to the dynamics of canopy structure during the growth season. Artemisia ordosica is a typical subshrub, very different from trees and shrubs. Assessing the influence of canopy structure and rainfall on stemflow yield in A. ordosica during the ...

  • Linking in situ vegetation data to the EUNIS habitat classification: results for forest habitats

    The EUNIS habitat classification provides the context for a number of policy-related ecosystem and habitat assessments, and is a European reference to which other national or regional classifications can be cross‑referenced when sharing geospatial data. Since 1995, it has been developed and managed by the European Topic Centre on Biological Diversity (ETC/BD), formerly known as the European ...

  • A study on crown interception with four dominant tree species: a direct measurement

    An experiment was conducted to concentrate on the rainfall interception process of individual trees for four common species in Beijing, China, which included needle species (Platycladus orientalis and Pinus tabulaeformis) and broadleaf species (Quercus variabilis and Acer truncatum). Two types of interception storages, the maximum ...

  • Polybrominated diphenyl ethers and new polybrominated flame retardants in tree bark from western areas of China

    Tree bark samples were collected from 15 sites across Western China in 2013, and the polybrominated diphenyl ether (PBDE) and new polybrominated flame retardant (NBFR) concentrations in the samples were determined. The mean total PBDE concentration was 51.8 ng/g lipid weight (lw), 85.2–99.4% lower than Chinese eastern coastal areas and the E‐waste recycling areas, BDE209 was the dominant PBDE ...

  • Water-retention potential of Europe`s forests

    A European overview to support natural water-retention measures One third of European territory is covered by forests (210 million ha). Approximately 296 million European inhabitants live in — or close to — forests. European forests are also closely connected to much of the hydrological network, and serve large groundwater bodies and many river sources. Forests provide more ...

  • New study shines a light on bird loss due to illegal logging in Ghana

    The combination of legal and illegal logging in southwest Ghana’s tropical forests is having a devastating impact on bird populations in the region, according to new research published recently in the journal Biological Conservation. Between 1995 and 2010, logging in the Upper Guinea rain forest ...

  • Seeing the forest and the trees, all 3 trillion of them

    A new Yale-led study estimates that there are more than 3 trillion trees on Earth, about seven and a half times more than some previous estimates. But the total number of trees has plummeted by roughly 46% since the start of human civilization, the study estimates. Using a combination of satellite imagery, forest inventories, and supercomputer technologies, the international team of researchers ...

  • Comparative study of isotherm parameters of lead biosorption by two wastes of olive-oil production

    Batch isotherm studies were carried out on a laboratory scale: (i) to investigate the effectiveness to remove lead of two wastes (olive stone (OS) and olive tree pruning (OTP)), untreated and chemically treated; and (ii) to examine the applicability of various adsorption isotherms to fit the experimental data. Results from tests were analyzed using seven equilibrium isotherm correlations ...

  • Forest disturbance effects on snow and water yield in interior British Columbia

    Long-term studies at Mayson Lake (ML) and Upper Penticton Creek (UPC) in British Columbia's southern interior quantify snow-dominated hydrologic response to natural disturbances and logging. Following natural disturbance at ML, changes in snow accumulation related directly to mountain pine beetle attack were measurable by the fifth year following attack, when canopy transmittance had ...
