Auwahi Dryland Forest Restoration Project
The Auwahi Dryland Forest Restoration Project has produced a substantial forest on the southwestern slopes of Haleakala on the island of Maui. The mostly volunteer-based restoration focuses on the 4,000-foot elevation range. History Pre-contact dryland forest ecosystems were reduced to less than five percent of their original range by clearing, grazing and invasive species in the late 1800s. The wood went to fuel the boilers at sugarcane mills and to make charcoal. By the early 1900s, the land was almost totally bereft of `ohi`a and koa trees. Kikuyu grass was imported in the 1940s and became pervasive. Restoration was initiated in 1997 by fencing a 10-acre area of Ulupalakua Ranch, using U.S. Fish and Wildlife Service funds. It was led by retired United States Geological Survey biologist Art Medeiros. In June 2003, the Leeward Haleakala Watershed Restoration Partnership was formed and supported the project. The partnership brought eight large landowners (holding 43,715 acr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santalum
''Santalum'' is a genus of woody flowering plants in the Santalaceae family, the best known and commercially valuable of which is the Indian sandalwood tree, '' S. album''. Members of the genus are trees or shrubs. Most are root parasites which photosynthesize their own food, but tap the roots of other species for water and inorganic nutrients. Several species, most notably ''S. album'', produce highly aromatic wood, used for scents and perfumes and for herbal medicine. About 25 known species range across the Indomalayan, Australasian, and Oceanian realms, from India through Malesia to the Pacific Islands, as far as Hawaii and the Juan Fernández Islands off the coast of South America. Indian sandalwood (''S. album'') is found in the tropical dry deciduous forests of India, the Lesser Sunda Islands of Indonesia, and Arnhem Land of northern Australia. It is the only species of the genus found on the Asian mainland, and may have been introduced to India from the Less ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dodonaea Viscosa
''Dodonaea viscosa'', also known as the broadleaf hopbush, is a species of flowering plant in the ''Dodonaea'' (hopbush) genus that has a cosmopolitan distribution in Tropics, tropical, Subtropics, subtropical and warm temperate regions of Africa, the Americas, southern Asia and Australasia. ''Dodonaea'' is part of Sapindaceae, the soapberry family. This species is notable for its extremely wide distribution, which it achieved only over the last 2 million years (from its region of origin in Australia) via oceanic dispersal. Harrington and Gadek (2009) referred to ''D. viscosa'' as having "a distribution equal to some world’s greatest transoceanic dispersers". Common names The common name hopbush is used for ''D. viscosa'' specifically and also for the genus as a whole. In the south Indian state of Tamil Nadu, this plant is called ''virāli'' (விராலி). Australian common names include: broad leaf hopbush, candlewood, giant hopbush, narrow leaf hopbush, sticky hopbus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbicide
Herbicides (, ), also commonly known as weedkillers, are substances used to control undesired plants, also known as weeds.EPA. February 201Pesticides Industry. Sales and Usage 2006 and 2007: Market Estimates. Summary in press releasMain page for EPA reports on pesticide use ihere Selective herbicides control specific weed species, while leaving the desired crop relatively unharmed, while non-selective herbicides (sometimes called total weedkillers in commercial products) can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact. Apart from selective/non-selective, other important distinctions include ''persistence'' (also known as ''residual action'': how long the product stays in place and remains active), ''means of uptake'' (whether it is absorbed by above-ground foliage only, through the roots, or by other means), and ''mechanism of action'' (how it works).

Axis Deer
The chital or cheetal (''Axis axis''; ), also known as the spotted deer, chital deer, and axis deer, is a deer species native to the Indian subcontinent. It was first described and given a binomial name by German naturalist Johann Christian Polycarp Erxleben in 1777. A moderate-sized deer, male chital reach and females at the shoulder. While males weigh , females weigh around . It is sexually dimorphic; males are larger than females, and antlers are present only on males. The upper parts are golden to rufous, completely covered in white spots. The abdomen, rump, throat, insides of legs, ears, and tail are all white. The antlers, three-pronged, are nearly long. Etymology The vernacular name "chital" (pronounced ) comes from ''cītal'' ( hi, चीतल), derived from the Sanskrit word ' (चित्रल), meaning "variegated" or "spotted". The name of the cheetah has a similar origin. Variations of "chital" include "cheetal" and "cheetul". Other common names for the chit ...

Avian Malaria
Avian malaria is a parasitic disease of birds, caused by parasite species belonging to the genera ''Plasmodium'' and '' Hemoproteus'' (phylum Apicomplexa, class Haemosporidia, family Plasmoiidae). The disease is transmitted by a dipteran vector including mosquitoes in the case of ''Plasmodium'' parasites and biting midges for ''Hemoproteus.'' The range of symptoms and effects of the parasite on its bird hosts is very wide, from asymptomatic cases to drastic population declines due to the disease, as is the case of the Hawaiian honeycreepers. The diversity of parasites is large, as it is estimated that there are approximately as many parasites as there are species of hosts. Co-speciation and host switching events have contributed to the broad range of hosts that these parasites can infect, causing avian malaria to be a widespread global disease, found everywhere except Antarctica. Cause Avian malaria is most notably caused by ''Plasmodium relictum'', a protist that infects birds i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windward
Windward () and leeward () are terms used to describe the direction of the wind. Windward is ''upwind'' from the point of reference, i.e. towards the direction from which the wind is coming; leeward is ''downwind'' from the point of reference, i.e. along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side". If the vessel is heeling under the pressure of crosswind, the lee side will be the "lower side". During the Age of Sail, the term ''weather'' was used as a synonym for ''windward'' in some contexts, as in the ''weather gage''. Because it captures rain, the windward side of a mountain tends to be wet compared to the leeward it blocks. Origin The term "lee" comes from the middle-low German word // meaning "where the sea is not exposed to the wind" or "mild". The terms Luv and Lee (engl. Windward and Leeward) have been in use since the 17th century. Usage Windward and leeward directions (and the points o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silviculture
Silviculture is the practice of controlling the growth, composition/structure, and quality of forests to meet values and needs, specifically timber production. The name comes from the Latin ('forest') and ('growing'). The study of forests and woods is termed ''silvology''. Silviculture also focuses on making sure that the treatment(s) of forest stands are used to conserve and improve their productivity. Generally, silviculture is the science and art of growing and cultivating forest crops, based on a knowledge of silvics (the study of the life-history and general characteristics of forest trees and stands, with particular reference to local/regional factors). The focus of silviculture is the control, establishment and management of forest stands. The distinction between forestry and silviculture is that silviculture is applied at the stand-level, while forestry is a broader concept. Adaptive management is common in silviculture, while forestry can include natural/conserved land ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquifer
An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or ''aquifuge''), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could create a confined aquifer. The classification of aquifers is as follows: Saturated versus unsaturated; aquifers versus aquitards; confined versus unconfined; isotropic versus anisotropic; porous, karst, or fractured; transboundary aquifer. Challenges for using groundwater include: overdrafting (extracting groundwater beyond the Dynamic equilibrium, equilibrium yield of the aquifer), groundwater-related subsidence of land, gro ...

Fusarium Oxysporum
''Fusarium oxysporum'' (Schlecht as emended by Snyder and Hansen), an ascomycete fungus, comprises all the species, varieties and forms recognized by Wollenweber and Reinking within an infrageneric grouping called section Elegans. It is part of the family Nectriaceae. Although their predominant role in native soils may be as harmless or even beneficial plant endophytes or soil saprophytes, many strains within the ''F. oxysporum'' complex are soil borne pathogens of plants, especially in agricultural settings. Taxonomy While the species, as defined by Snyder and Hansen, has been widely accepted for more than 50 years, more recent work indicates this taxon is actually a genetically heterogeneous polytypic morphospecies, whose strains represent some of the most abundant and widespread microbes of the global soil microflora. Genome The ' family of transposable elements was first discovered by Daboussi ''et al.'', 1992 in several ''formae speciales'' and Davière ''et al.'', 2001 ...

Hawaiian Language
Hawaiian (', ) is a Polynesian language of the Austronesian language family that takes its name from Hawaii, the largest island in the tropical North Pacific archipelago where it developed. Hawaiian, along with English, is an official language of the US state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840. For various reasons, including territorial legislation establishing English as the official language in schools, the number of native speakers of Hawaiian gradually decreased during the period from the 1830s to the 1950s. Hawaiian was essentially displaced by English on six of seven inhabited islands. In 2001, native speakers of Hawaiian amounted to less than 0.1% of the statewide population. Linguists were unsure if Hawaiian and other endangered languages would survive. Nevertheless, from around 1949 to the present day, there has been a gradual increase in attention to and promotion of the language. Public Hawaiian-langua ...
