The Rensselaer Plateau is a small plateau located in the central portion of Rensselaer County, New York; it generally encompasses significant parts of the towns of Berlin, Stephentown, Sand Lake, Poestenkill, and Grafton, along with small sections of several other nearby towns.
 Many glacial lakes, including Big Bowman Pond, Little Bowman Pond, Round Pond and Spring Lake are located on the plateau.
 Elevations on the plateau range from 1,000 to 2,000 feet (305 to 610 meters) above sea level.
 Vegetation on the plateau is more similar to that found in the Adirondack Mountains to the northwest, with abundant Eastern White Pine, Eastern Hemlock, Red Spruce, and Balsam Fir, along with more limited occurrences of Red Pine and Tamarack.
 While most to all of the plateau was logged late in the 19th Century and early in the 20th Century, little farming was undertaken afterwards due to extremely poor and rocky soils, allowing much of the forest to regenerate.
The Central Flyway is a bird migration route that generally follows the Great Plains in the United States and Canada.
 The main endpoints of the flyway include central Canada and the region surrounding the Gulf of Mexico; the migration route tends to narrow considerably in the Platte River and Missouri River valleys of central and eastern Nebraska, which accounts for the high number of bird species found there.
 Some birds even use this flyway to migrate from the Arctic Ocean to Patagonia.
 Routes used by birds are typically established because no mountains or large hills block the flyway over its entire extent.
 Good sources of water, food, and cover exist over its entire length.
The Central Canada Hockey League Tier 2 is a Canadian Junior ice hockey league operating in Eastern Ontario.
 The league is sanctioned by Hockey Eastern Ontario and Hockey Canada.
 The 16 member team of the league compete for the Barkley Cup and acts as a second tier to the Central Canada Hockey League.
 Dating back to the 1960s, the league was known until 2015 as the Eastern Ontario Junior B Hockey League.
Erythrina abyssinica is a tree species of the genus Erythrina belonging to the plant family of the Fabaceae (or Leguminosae) described by Augustin Pyramus de Candolle in 1825.
 This leguminous tree species is native to East Africa , Eastern DRC and southern Africa.
Cornus hongkongensis (sometimes called "Benthamidia hongkongensis", "Dendrobenthamia hongkongensis", or Hong Kong dogwood) is a species of evergreen dogwood native to China, Laos, and Vietnam.
 It grows to 15 meters in height and blooms in late spring to early summer, exhibiting an abundance of fragrant flowers.
 Because this species of dogwood also exhibits a range of minor differences in morphology due largely to geographic distribution, it has been divided into a number of subspecies.
 It has been described as an excellent ornamental tree species.
Mitragyna parvifolia is a tree species found in Asia.
 It is native to India and Sri Lanka.
 Mitragyna species are used medicinally as well as for their fine timber throughout the areas they grow.
 It reaches heights of 50 feet with a branch spread of over 15 feet.
 The stem is erect and branching.
 Flowers are yellow and grow in ball-shaped clusters.
 Leaves are a dark green in color, smooth, rounded in shape, and opposite in growth pattern.
Tecomella undulata is a tree species, locally known as rohida in Urdu "روہیڑا" found in Thar Desert regions of India and Pakistan.
 It is a medium-sized tree that produces quality timber and is the main source of timber amongst the indigenous tree species of desert regions of Shekhawati and Marwar in Rajasthan.
 The trade name of the tree species is desert teak or Marwar teak.
The Mississippi Flyway is a bird migration route that generally follows the Mississippi River in the United States and the Mackenzie River in Canada.
 The main endpoints of the flyway include central Canada and the region surrounding the Gulf of Mexico.
 The migration route tends to narrow considerably in the lower Mississippi River valley in the states of Missouri, Arkansas, Mississippi, and Louisiana, which accounts for the high number of bird species found in those areas.
 Some birds use this flyway to migrate from the Arctic Ocean to Patagonia.
Abies balsamea or balsam fir is a North American fir, native to most of eastern and central Canada (Newfoundland west to central British Columbia) and the northeastern United States (Minnesota east to Maine, and south in the Appalachian Mountains to West Virginia).
Carya aquatica (bitter pecan or water hickory) is a large tree, that can grow over 30 m tall of the Juglandaceae or walnut family.
 In the American South it is a dominant plant species found on clay flats and backwater areas near streams and rivers.
 The species reproduces aggressively both by seed and sprouts from roots and from stumps of cut trees.
 Water hickory is a major component of wetland forests now in the south eastern US, because of the selective cutting of more desirable tree species for the lumber industry.
 It is considered important in cleansing drainage waters since the plants slow water flow during flooding, allowing sediments to fall out of the water column.
 This tree species is tolerant of wet soils but grows best on well draining soils near rivers and other water ways.
