The Campaign to Save Native Forests (W.A.) (CSNF) was the name of a grassroots organisation which grew from a campaign started in Perth, Western Australia, in 1975, as a response to the development of a woodchipping industry in the south-west Jarrah and Karri forests of Western Australia.
 The Manjimup woodchip project aroused significant levels of protest in Perth and the South West region out of public concern that inadequate measures had been made for conservation alongside exploitation of the south west hardwood forests.
Ageratina adenophora, commonly known as crofton weed or sticky snakeroot, is a species of flowering plant in the daisy family native to Mexico and Central America.
 Originally grown as an ornamental plant, it has become invasive into farmland and bushland worldwide.
 It is toxic to horses, who develop respiratory disease after eating it.
Europe first participated in the Little League World Series in .
 Teams from Europe were given a berth in the LLWS each year between 1960 and 2000 (with the exception of the temporary ban of international teams in ).
 In 2001, the region was split into two co-terminus regions: Europe (later EMEA) Region and Transatlantic Region.
 The Europe Region comprised mostly native European teams while the Transatlantic Region comprised mostly American expatriates.
 This distinction was eliminated in 2008; from 2008 to 2012, teams made up of either native Europeans or American expatriates were eligible to qualify from the Europe Region.
Phacelia adenophora is a species of phacelia known by the common name glandular yellow phacelia.
 It is native to the northwestern United States where it can be found in Oregon, northeastern California, and northwestern Nevada.
 It grows in mountain and plateau habitat.
 This is an annual herb producing decumbent, creeping, spreading, or upright branched stems up to 40 centimeters long.
 The leaves are oblong in shape and deeply lobed, measuring up to 3 centimeters long.
 The inflorescence is a one-sided cyme of many bell-shaped flowers each under a centimeter long.
 Unlike many phacelias, which bloom in shades of blue and purple, this species has yellow to golden flowers.
 It occasionally has purple edges on the corolla.
 The fruit is a fuzzy, oblong capsule a few millimeters in length containing up to 14 seeds.
Spinney Hills is in East Quogue, New York on the eastern end of the Long Island Central Pine Barrens region.
 It is often used as a hiking, hunting, and off-roading area for dirt bikers, quadders, paintballers, and four-wheelers that includes miles of trails with near beach sand consistency.
 Spinney hills gets its name because of Spinney Road, which used to connect the East Quogue side of the hills to Sears Bellows County Park and Flanders (home of the Big Duck) to the north prior to the construction of the Sunrise Highway New York State Route 27.
 This region was created by glacial deposits of rock and sand during the last ice age.
 The sandy soil also absorbs most rainfall so there are few ponds or rivers in the area.
 There is a shallow glacial well in Spinney Hills known as an aquifer, which is where most of the rainfall in the region is stored.
 These hills are the continuation of a long east west ridge of hills known as the Ronkonkoma Moraine, which form the 'backbone' of Long Island.
 Much of this region is undeveloped other than a sand mine to the west and Southampton Pines to the east.
 There have been large scale legal battles between private real estate companies and the Town of Southampton over the future of the area, being it is one of the last expanses of wilderness left on Long Island.
 There is a very large native population of white-tailed deer in the region due to lack of natural predators.
 In the higher elevations small sections of the hills have an almost alpine-desert look, with sandy open plateaus and extremely dwarfed vegetation .
 The Dwarf Pitch Pine which dominate the region grow not much taller than twenty feet in height due to dry, nutrient-poor soil.
 There is a desert effect in the Pine Barrens, with relatively higher daytime temperatures and cooler nighttime temperatures than the coast, only a few miles away.
 There are spectacular views of the Atlantic Ocean and Peconic Bay from certain peaks in this region if one knows where to hike.
 The consistent ocean breeze at the higher elevations passing through the long brushy needles of the Dwarf Pitch Pines creates a gentle whisping sound, or white noise, adding a peaceful ambience to the big skies and expansiveness one feels in this region.
The political history of medieval Karnataka spans the 4th to the 16th centuries, when the empires that evolved in the Karnataka region of India made a lasting impact on the subcontinent.
 Before this, alien empires held sway over the region, and the nucleus of power was outside modern Karnataka.
 The medieval era can be broadly divided into several periods: The earliest native kingdoms and imperialism; the successful domination of the Gangetic plains in northern India and rivalry with the empires of Tamilakam over the Vengi region; and the domination of the southern Deccan and consolidation against Muslim invasion.
 The origins of the rise of the Karnataka region as an independent power date back to the fourth-century birth of the Kadamba Dynasty of Banavasi, the earliest of the native rulers to conduct administration in the native language of Kannada in addition to the official Sanskrit.
 This is the historical starting point in studying the development of the region as an enduring geopolitical entity and of Kannada as an important regional language.
Adenophora is a genus of flowering plants in the family Campanulaceae, the bellflowers.
 Plants of this genus are known commonly as ladybells.
 Most are native to eastern Asia, with a few in Europe.
 Many are endemic to either China or Siberia.
Pterostyrax, the epaulette tree, is a small genus of four species of deciduous large shrubs or small trees in the family Styracaceae, native to eastern Asia in China and Japan.
 They grow 4 - tall, with alternate, simple ovate leaves 6 - long and 4 - broad.
 The flowers are white, produced in dense panicles 8 - long.
 The fruit is an oblong dry drupe, with longitudinal ribs or narrow wings (the wings are absent in the related genus "Styrax", whence the name "Pterostyrax", "winged styrax").
Pterostyrax hispidus, the epaulette tree or fragrant epaulette tree, is a species of flowering plant in the family Styracaceae, native to China and Japan.
 Growing to 15 m tall by 12 m broad, it is a substantial, spreading, deciduous shrub with oval leaves up to 20 cm long, and clusters of pure white, fragrant, pendent flowers in summer.
The Texas Hill Country is a geographical region located in the Edwards Plateau at the crossroads of West Texas, Central Texas, and South Texas.
 Given its geographical location, terrain features, and native vegetation, the Hill Country could be considered the beginning or end of the American Southwest (depending on which direction one is travelling).
 The region is notable for its karst topography and tall rugged hills of limestone or granite.
 Many of the hills rise to a height of 400-500 feet above the surrounding plains and valleys, with Packsaddle Mountain rising to a height of 800 feet above the Llano River in Kingsland.
 The Hill Country also includes the Llano Uplift and the second-largest granite dome in the United States, Enchanted Rock.
 The terrain throughout the region is punctuated by a thin layer of topsoil and a large number of exposed rocks and boulders, making the region very dry and prone to flash flooding.
 Native vegetation in the region includes various yucca, prickly pear cactus, desert spoon, and wildflowers in the Llano Uplift.
 The predominant trees in the region are ashe juniper and Texas live oak.
